TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Overnight Thunderstorms most likely woke you up from Running Springs to Crestline around 1:00am. Lots of Lightning and Thunder roared along with anywhere from light rain to a downpour, depending on your location. Today we should have more storms around the area as Monsoonal Moisture continues to flow into the Mountains of SoCal. Precipital Water levels will be close to 1.4″ at times over the next couple of days so the likelihood of rain will be good. As for Flash Flooding, this is always a possibility with Thunderstorms, so be careful if you are out in the back country or in an area where heavy runoff is likely to occur. Due to the increased cloud cover that is expected today, high Temperatures will be a little cooler than what we have had for the last several days. Highs today will be from 85-95* in the Crestline and Lake Arrowhead areas. Running Springs and Big Bear should have a good chance for T/Storms today through Friday night with rain accompanying these storms. Temperatures will be cooler there as well with high in the mid to upper 70s and maybe a few 80* readings in some nearby areas. Here’s some trivia, Petrichor, is the name for the smell when the rain first arrives. It is caused from the cool rain hitting the warm asphalt. Rainfall overnight varied considerable across the area, Crest Park had .20″ reported while most other areas had just a few hundredths. As it looks this morning, later this afternoon through Friday we should have a good chance for T/Storms most anywhere across the local area. Use caution during these events while driving or whatever you may be doing. Go inside your house if possible to be safe from Lightning strikes. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Yesterday in Big Bear, Thunderstorms developed bringing rain and cooler temperatures during the afternoon to the area. Rainfall amounts varied quite a bit. Shay Meadows reported .11″ while Big Bear city reported .52″. Today, more T/Storms will be likely for the Big Bear area and possibly spreading to the West to include the Arrowhead and Crestline areas as well by late afternoon. High pressure will remain stationary across the West continuing the current heat wave through the weekend and into next week. This will also continue to feed Monsoonal Moisture into the area through the same time frame. The possibility of a Thunderstorm at any time will be possible over the next five days. Thursday and Thursday night, nocturnal Thunderstorms will be likely as well running into Friday and throughout the day. The only cooling locally will be from clouds and any T/Storms that develop locally. Highs today an for the next several days will remain in the mid to upper 90s for the Crestline and Arrowhead areas. Overnight lows will be in the mid 60s as well. Big Bear and Running Springs will be a little cooler with Thunderstorms likely there. This will help to keep the daytime highs in the mid 80s there. Mid level moisture from the 10k’ level to around the 25k’ level will be good over the next few days to aid in storm development. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
This morning, a band of Tropical Moisture is moving West across Southeastern California toward our area. This will bring more clouds and a chance for a T/Storm later today for the mountains and especially Big Bear and the Yucca Valley. Yesterday, a couple of T/Storms popped up in those same areas with some Lightning reported near Big Bear. Temperatures will again be very warm for all of the Mountain areas as well as the Valley. Highs for Crestline and Arrowhead will in the mid to upper 90s with afternoon clouds. Overnight lows will be in the upper 60s to low 70s. Big Bear and Running Springs will be in the mid to upper 80s with overnight lows in the mid 50s to mid 60s for R/S. San Bernardino will see highs today in the 105-111* range with overnight lows in the mid to upper 70s. High pressure over the Great Basin will continue to give SoCal very warm temperatures through the Holiday weekend. The only break will come from whatever cloud cover we get locally. Thursday and Thursday night we will have a fairly good chance at some thunderstorm activity with nocturnal storms possible as well. Gusty winds will accompany any storms that do develop, other that that, winds locally will be light and variable. We will continue to be under a HEAT ADVISORY through Sunday for hot temperatures and Very High Fire Danger levels.
Harvey is still wreaking havoc along the Texas coastal areas and the Houston area. More rain is expected today and tomorrow before he starts to move North East. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
High pressure over the Great Basin and Hot temperatures will be the forecast for the next five days, or more. As parts of Texas see unprecedented rainfall amounts continuing through the week, the West Coast will remain dry and hot. The area of High pressure centered over the Great Basin will remain strong and in place for the next several days. We will see an increase in Monsoonal Moisture filtering into the mid levels of the atmosphere over the next few days. This will give us afternoon clouds and a weak chance for Thunderstorms development over and near the mountains through the week ahead. Currently, a MCS is moving toward SoCal from the East but is slowly dissipating over the Eastern Deserts and most likely will only bring mid to high clouds to our area later this morning. Temperatures today will again be from 90-96* for the Crestline and Lake Arrowhead areas. Overnight lows will be quite warm as well with temperatures in the upper 60s to low 70s. The Big Bear, Running Springs and surrounding areas will be a little cooler with highs in the low to mid 80s and overnight lows in the upper 50s to mid 60s. These areas will have a better chance to see thunderstorm activity today and in the coming days. Winds will be light and variable through the period with gusty winds around any storms that may develop. This will be the forecast for the next several days with very little change expected. Be sure to have plenty of water available for you and your pets. A HEAT ADVISORY will remain in effect through Thursday, at least. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Yesterday, temperatures across the area ranged from 83* in Big Bear and Running Springs, to 94* at Valley of the Moon, and 104* in San Bernardino. Today will be pretty close to the same as far as temperatures go. Earlier this morning, mid level clouds moved through the area, mostly across the Mountain area but have gone now as of 9:00am. High pressure continues to build in the Great Basin area of the West. This will bring more hot weather to all of California through mid week. To our North in the Sacramento and San Joaquin Valley a trough of low pressure will bring a nice break from the heat there beginning around mid week. As the ridge of high pressure builds across the Southland, Monsoonal Moisture will get caught up in the circulation at the mid levels of the atmosphere. This will give us afternoon clouds and an increasing chance for a Thunderstorm as we head into next week. We will continue to have hot weather through Thursday with some cooling from whatever clouds do develop. The area of high pressure should begin to slowly break down late in the week with a slow cooling trend beginning at that time for SoCal. Afternoon clouds and possible T-Storms will be with us through the Holiday weekend as it looks at this time. Tuesday and Wednesday look like our best chance for a shower and or T-Storm, and then again later in the week. A Tropical system is beginning to develop off of the Southern tip of Baja California. It is possible that some of the spin off moisture from Harvey will be entrained in this system as it moves North along Baja. As it looks this morning, this Tropical system will move North paralleling the coast of Baja. So we may see some effects from this by the middle to late in the work week ahead.
On another note, once Hurricane Harvey continues to sit over the Gulf Coast of Texas this morning and will continue to do so for the next several days. Major Flooding will be a big problem as up to 30″ of rain will fall in some areas there. Harvey will weaken slightly today as a low pressure system, then move slightly offshore, strengthen again and move back onshore again around Tuesday continuing to bring moderate to heavy rain to the rain soaked areas of the Gulf Coast of Texas.

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
Harvey, has gone from a Tropical Depression to a CAT4 Hurricane, and back to a Tropical Depression in just three days. Today the people of Texas and the surrounding counties and States will conduct a search and rescue as well as an assessment of what has happened to the area. Thoughts and prayers to that area and all affected in that region. Harvey, will continue to remain over the same area of Texas for the next couple of days bringing more rain and gusty winds to that area. Rainfall estimates are for some places to receive up to 25″s of moisture before the remnants of Harvey have moved on. By Tuesday of next week, the remnants of Harvey’s moisture will likely move to the West being caught up in the circulation of High pressure over the Western U.S. There will be a chance for the SoCal area to see some of that moisture toward the middle of next week as a Tropical system develops to our south, and may entrain leftover Tropical moisture from once Hurricane Harvey, as it moves North along the Baja Coast. For today, HOT, the same for the next five days as a stagnant air mass will remain stationary over the South West. Highs in the low to mid 90s can be expected for Crestline and Lake Arrowhead, especially along the Northern parts of Arrowhead. Running Springs, Arrowbear, Green Valley Lake, and Big Bear will all be a little cooler with highs expected to be from the mid to upper 80s, through the period. Slight cooling will begin Thursday, as the High starts to break down toward the end of next week. Mid level clouds will be around this afternoon and increase in coverage over the next few days as mid level moisture flows in from South, possibly moderating the temperatures to some degree. Tomorrow, and Tuesday we will have a fairly good chance for Pop Up Thunderstorms to develop in the San Bernardino Mountain areas, again as mid level moisture flows in to the area. Early next week a Tropical system will develop off of the Southern tip of Baja. This system will likely become a Hurricane around mid week, and move North, paralleling the Baja Peninsula. Around the 3rd of September, we may see some effects from this system as it gets close to SoCal as a Tropical Depression. The models are not in agreement as to the exact path of this system at this time, but this is one scenario. The winds over the next few days will be light and variable as daytime heating and nighttime cooling will control the air flow across the Mountain. Enjoy the nice late Summer weather as Fall is rapidly approaching. Drink plenty of water and don’t forget about your pets, they need water and shade too. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:



Good Morning.
This morning, all eyes will be on Hurricane Harvey. Currently expected to make landfall as a CAT3 or maybe a weak CAT4, near Corpus Christy Texas, later today or early this evening. Atmospheric conditions across the Continental U.S will most likely hold Harvey in place once landfall is made for at least two days. Major flooding is expected with as much as 24+ inches of rain possible in some areas to the North and East of Harvey’s center. The WEATHER CHANNEL is, and will be live with all info related to Harvey.
Today, we will begin a warming trends as High pressure builds over the Great Basin. Temperatures will be from the mid to upper 80s today, and the upper 80s to mid 90s for the next several days for the Crestline and Lake Arrowhead areas. For the upper elevations of Running Springs and Big Bear, temperatures will be in the upper 70s to low 80s through the period. A greater chance of Thunderstorms will be in the Big Bear area over the next few days as Tropical Moisture will get caught up in the circulation of the area of High pressure, and move over that area. As the high expands across the South West Region, temperatures will increase across all of SoCal. The Desert areas and the Valleys will have high temperatures in the upper 90s to 110* over the next five days. High temperatures are expected to peak Tuesday, beyond that only slight cooling can be expected through next weekend. Mid level moisture will feed into the local area on and off over the next week. This will keep a chance for clouds, and or Thunderstorms, around the area for the next week as well. This morning, Fog has moved into the Valley this morning, and is burning off as we speak. For the next four days, the Valley should remain clear of fog as temperatures soar. As the High develops over the Great Basin, we will have variable light winds across the area. Humidity levels will lower making for increased fire Danger Levels, but no big wind event is likely. VERY HIGH FIRE DANGER will continue through next week, please be careful with any outdoor fires or BBQ’s. The Weather pattern will remain stagnant for the next several days. Don’t forget about Fido, and all other outdoor animals as the heat affects them too. If you are planning any outdoor activities, make sure you have plenty of liquids available at all times. RC

Good Morning.
This morning, fog has moved into the Valley below. As of 5am, the marine layer is running from around the 1000′-3000′ level. This will move out by 11am leaving mostly clear skies today for the Valley. Along the Rim and the mountain communities, mostly clear skies this morning will be the forecast. Later today, mid level moisture will drift into the Mountain and Desert areas of SoCal. Some clouds will develop across the area with a slight chance again for a T-Storm along the Mountains and Deserts. Late in the day yesterday, as the Sun set, towering cumulus clouds could be seen in the distance to our North making for a nice Sunset. Temperatures today will be only slightly warmer than Wednesday’s with highs in the mid 80s for Arrowhead and Crestline. Temperatures will be a little cooler for the communities above that elevation. Tomorrow, the heat will begin. An area of high pressure will begin to expand and center itself in the Great Basin area. The High is expected to peak at 595dm over the Great Basin so the heat will be on. This will bring in very warm temperatures to the IE and the local Mountain communities. This will also bring a stagnant air mass over SoCal through next Wednesday with temperatures in the 90s locally and in the 105-112* range through the period in the Valley and Desert areas. Any winds will be light and variable for the next few days. The Fire Danger levels will be elevated locally, but I don’t see any strong winds at this time to bring the FD level to Critical. We have had a nice break from the excessive heat, but it will return for the next several days. The Monsoonal Moisture will move East for a few days toward AZ and New Mexico for now. So hopefully the humidity levels will be lower for this heat wave. Don’t forget about your pets they get hot too. RC

Good Morning.
Today we will have the last day of somewhat cool weather as low pressure now over SoCal will move out by Tomorrow. High pressure from the south will build over from SoCal beginning late Thursday bringing in much warmer temperatures through next week. Locally, the daytime high temps will be from the upper 80s to low 90s by the weekend for the Arrowhead and Crestline areas. Overnight lows will be warmer as well with overnight lows in the mid to upper 60s locally. Big Bear and Running Springs will also be much warmer for the weekend ahead with highs in the low 80s expected there. Today, we may see some towering cumulus develop in some areas as a weak wave of energy passes through later today. There will be a 25% chance that a Thunderstorm could develop most anywhere across the mountain region. The Valley is clear this morning and is preparing for HOT temperatures in the coming days. High temperatures in the San Bernardino Valley will be warming to 100-110* over the next few days. Overnight lows are not expected to have good recovery with nighttime lows in the 70s. RC

Good Morning.
Well, the Eclipse was a little disappointing yesterday locally, if you didn’t know what was happening, you most likely would have never known. At least the weather was good for viewing for what there was to see. Ok, enough of that. Today we will have mostly clear skies with only some afternoon clouds at the mid levels. It doesn’t look like there’s enough moisture for thunderstorm development locally, or over the Big Bear area today. Temperatures for the Crestline and Arrowhead areas will be in the upper 70s to low 80s today. Overnight lows will run in the mid to upper 50s to low 60s. Big Bear and Running Springs will be a little cooler as usual with highs today in the mid to upper 70s and overnight lows in the upper 40s to low 50s. Tomorrow, we will have a better chance for clouds and or an isolated Thunderstorm to develop over the local area as the low pressure will begin to move East bringing the center of the low over SoCal. There is not a lot of moisture associated with this low so the chances of a T/Storm will be around 25% during the afternoon hours. Temperatures across the area tomorrow will be a little cooler before High pressure moves in from the South and a warming trend begins. Temperatures will be on the rise through the early part of next week. The weekend should bring the warmest temperatures to the local mountain region with highs expected to reach into the upper 80s to low 90s for Arrowhead and Crestline. No monsoonal moisture is expected at this time for the next five days.RC
