TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
First off, on the EL NINO page, (website) I have posted the latest update as to the status of EL NINO from the CPC and IRI as of December 13th along with a few graphics.
This morning we have a slight offshore pressure gradient across SoCal. Daggett is at 1021.3mbs, and San Diego is at 1018.4mbs, so that is about a 3mb offshore flow. Very weak. For today and Sunday, we will have clear skies for most of SoCal as a Ridge of High pressure moves across the area. Temperatures will warm up a few degrees along with light and variable winds will make for a very nice weekend. Monday, a quick moving Trough will move through California. SoCal will be at the bottom of this Trough as it moves through the West. Increasing clouds with Ridge Fog will be likely Monday through Tuesday morning. We will also have a chance for a few showers locally, but the Subtropical moisture that has fed the last few systems will be nowhere to be found. So rainfall totals will be light. After that system moves out to the East, High Pressure will move in from the South bringing in much warmer temperatures along with a SW flow through Christmas. So as it looks this morning, after Monday’s system we will be clear of any storms until after the 25th. A Zonal flow will last for the next week or so. Then we will probably see a change back to more winter like weather with systems coming through the flow with regularity again. Currently on EL NINO, the SST’s continue to be warmer than normal in the 3.4 ENSO region.( This is the area that is used to measure the strength of El NINO) However, the atmosphere has yet to show any signs of coupling with the warmer than normal SST’s.(Sea Surface Temperatures, SST’s) So even though we have had several storms with a Tropical moisture feed, so far, the presence of El NINO has yet to show up.

That’s it for now. Thank you for joining me @ lakegregoryweather.com

Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning Weather Watchers.
For today. High clouds will move across the SoCal region thickening as the day wears on. Late this afternoon or evening as a weak wave moves across the area, there will be a very slight chance for a sprinkle from the tail end of this Trough, as it moves Inland. Tomorrow, we will have mostly clear skies as High pressure builds into the West briefly. Sunday will be mostly clear as well but another weak Trough will move Inland to our North again bringing a chance for light showers to the local Mountains on Monday. Tuesday, we will return to building High Pressure over the Great Basin that will bring clear weather through the work week.
That’s it for now. Thank you for joining me @ lakegregoryweather.com

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning, Weather Watchers.
This morning we have clear skies across most all of SoCal. A Ridge of High pressure will cover the West today bringing sunny skies and a little warming with it. Offshore flow will continue through the day today, with some gusty winds along the Ridges and Canyons through this afternoon. Friday, A flow of Sub-Tropical clouds from the South West @ 15-30K’ coupled with a Trough passing through the PAC-NW, will keep temperatures a little cooler than today. Saturday and Sunday, we should have mostly clear skies with very nice weather for the mountains with daytime temperatures in the 55-65* range. Then another change for late Sunday night and Monday. A weak Trough will pass through the West. This will bring a chance for light precipitation early Monday morning locally. There are a few variables with this system. The Sub-Tropical flow may get picked up if the area of Low pressure splits off to become a Cut-Off Low over SoCal Monday. This will determine whether we do, or do not, get any rain, and if so, how much moisture we do get from this system. Currently, the models are at odds whether or not the Cut-Off Low will actually develop. So I will be watching this over the next couple of days as the models hash this out. On the long range Crystal Ball outlook, there doesn’t seem to be any changes in the Global pattern through Christmas, other than a couple weak systems in the flow for us. Everything appears to stay to our North for the time being. After Christmas, we may see a return to more potent systems dropping further South in to SoCal, one in particular around the 28th, as it looks this morning. That’s it for now. Thank you for joining me @ lakegregoryweather.com

Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning Weather Watchers.
It looks like we have a pretty nice week ahead. Today High clouds will continue to pass through the area making for a partly cloudy day. Temps will run in the low to mid 50s across the area for the daytime highs. Overnight lows will run from the low 20s in Big Bear to the low to mid 30s elsewhere. Currently, we are under an upper level Ridge of High pressure, this will move East later today. A weak long wave Trough will make its way South on Tuesday. We may see a few sprinkles Tuesday but nothing measureable is expected. Wednesday through Friday, we will have clearing skies locally as High pressure will set up in the Great Basin. NE winds will develop across the area again Wednesday and Thursday. Friday and Saturday we should have nice weather then late Next weekend we will have another chance for some precipitation locally, but that isn’t looking very promising at this time. Overall, we will have several days ahead to dry out from the recent rains. Temperatures in the Mountain areas will remain pretty cool while the Valley warms up nicely. RC

Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning, Weather Watchers.
Today a weak wave will pass through from the bottom of a cold front to our North, giving us a few high clouds and mild temperatures. Patchy fog and low clouds can be found at the Coast and in some of the inland Valleys this morning. Behind the Trough, High pressure will set up in the Great Basin late today or early Thursday. This will bring a return of an offshore flow at the lower elevations tomorrow below ~6000′ level. The upper level flow (above the ~6500-7000′ level) will remain onshore from the West. Gusty winds can be expected along the Ridges and in the Canyons on the local HWYs Thursday. Friday, things will settle down as another weak Trough passes through the area. More High clouds can be expected Friday. The SW Sub Tropical flow will bring in a thicker cloud cover Friday with a very slight chance for a shower. Saturday and Sunday will be nice weather but Monday there is another chance for a shower as another Trough moves through the flow. As it looks this morning, there are no significant systems in our immediate future as the Jet Stream is to our North and doesn’t show any signs of dropping for the next five days. Overall, we will continue to have the same weather pattern through the next five days with little variations. Enjoy! RC

Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning Weather Watchers.
The stream of High clouds that has been over SoCal for the last several days will finally move South and East today. This will open up clear skies later today continuing through Friday. Along with the clearing skies, a North East flow will set up across SoCal bringing in warmer temperatures to the Valley and drier weather for the Mountains. The surface pressure gradient from The Great Basin to the Coast will peak Thursday, this is when we will have the strongest winds across the area. Friday, a Trough will arrive in the Pac-NW, this will change the winds from the NE to the SW in SoCal. Temperatures will cool a little at that time. So really not to much going on with the weather over the next few days. Clear skies with typical December temperatures. The next chance for precipitation will be around the 17th as it looks this morning. RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning Weather Watchers.
This morning we had fog lying on Lake Gregory. made for a beautiful morning view.
Today, we will see increasing high clouds from the SW. The fog that has been hanging on the Rim should clear out today. The Valley is clear this morning as a NE flow aloft is scouring out the moisture from the recent rains. Surface pressure this morning at Tonopah is at 1031.5, Daggett is 1027.3, and San Diego is at 1024.2mbs. So overall, we will have a weak offshore flow across most of the area. Currently at Paivika Ridge the winds are 10-20mph from the NE with clear skies. Today we are under a transitory ridge of High pressure that will move East by tomorrow. The winds locally will turn to the SW as a Long Wave Trough passes through the West Monday and Tuesday. As the Trough arrives, we will see increasing SW winds and clouds, with a slight chance for a shower, mostly Monday night into Tuesday morning. As the Trough departs Wednesday, the winds will turn to the NE behind the departing Trough becoming gusty from 10-30mph. Along with the gusty winds, cold air advection from the Great Basin will keep temperatures on the cool side locally for Wednesday, and Thursday. Humidity and PWAT levels will be very low but due to the recent rains, the Fire Danger levels will be very low as well. On the longer range outlook, another weak looking system with a Sub Tropical moisture feed will arrive over the weekend. Rain or showers will be possible from this system late Saturday and Sunday aws it looks this morning. As always in the mountainous areas, Weather can change rapidly, so be sure to carry your tire chains, a warm blanket and a sheet of plastic to lay on while installing tire chains in your vehicle. Black Ice can hide around every corner so use extra caution while driving. Yesterday there were several accidents on our local roads due to ice on the roadways. Please be careful out there! RC

TODAY’S WEATHER DISCUSSION AND FORECAST:


Today’s Outlook for Crestline, Twin Peaks, Lake Arrowhead and the San Bernardino Mountains.

Good Morning.
Today and Sunday, we will see mostly clear skies as a Ridge of High pressure builds across the West. Temperatures will be a little warmer for the next two days during the day, but the nights will still drop down to the lower 30s with some areas in the upper 20s, so Black Ice will still be a problem in some areas due to moisture on the roads that can freeze. A Trough of Low pressure will move into the Pac-NW late Sunday, bringing more rain and snow to the North. Here we will see a strengthening onshore flow and increasing clouds. Tuesday we may have a few sprinkles and or snow showers to the upper elevations as the Trough passes through the area. Currently the Models are in complete disagreement as to what this next Trough will do for SoCal. On tomorrow’s outlook, I will have a much better vision on this. Wednesday and Thursday will be mostly clear but another chance for a storm will arrive over the weekend of DEC-15,16. One interesting item, there is a continuous feed of Sub Tropical moisture coming from the Hawaiian Islands feeding into the South West. This has been ongoing for a couple weeks now. There doesn’t seem to be much talk of El Nino, but you have to wonder if this is related? Hmmm? This is also why our storms have had good rainfall amounts. Otherwise they would have been dry or not at all. Anyway, more on that later. RC
