TODAY’S WEATHER DISCUSSION AND FORECAST:
..Good Morning. HAPPY BIRTHDAY TO MY WONDERFUL WIFE ROBIN!
..Today we begin a cooling trend. Temperatures will be coming down along with lower elevation humidity levels will be going up. However, the higher elevations will not see an increase in Humidity levels due to a dry thermal layer in place above the ~6300′ level. This will and is currently affecting the fire behavior this morning along with increasing gusty winds. I’ll have an update on that a little later today.
..A Trough of low pressure will be moving onshore to our North today. This will bring an increase in the winds locally, as well as a wind direction change. Temperatures will be cooler today, and continue to cool over the next couple of days. Humidity levels will still be pretty low mid day, for the mid slope foothill areas, so the Fire Danger levels will continue to be VERY HIGH for the afternoon hours each day along the front country. Please be careful!!
..As the Trough strengthens locally, the marine layer will deepen coupled with a Catalina Eddy, to help push morning fog and clouds further Inland through Friday morning. This will also further the cooling trend.
..Saturday the Trough will weaken but temperatures will still remain at about average for this time of year through mid week next week as weak troughing remains offshore.
..Gusty winds, especially in the passes during the afternoon and evening hours will continue. This morning at Lake Arrowhead the winds were from the SW @ 10-15 mph, at my location SW @ 8-12mph, and the Cajon pass has winds from the WSW @ 17-25mph . Across the mountain the humidity levels are up from yesterday below the ~6500′ elevation by almost 20%. Above 6500′ they are still in the low teens.
..Looking out into the future, an area of low pressure will continue to remain in place offshore from Nor-Cal helping to keep our temperatures in check through mid week next week. This will also keep the Monsoon away from the SoCal region.
..Today’s FIRE DANGER LEVELS will continue to be VERY HIGH during the afternoon as humidity levels drop and temperatures reach peak heating.
..Please be careful out doors during this period of High Fire danger. Welding, BBQ’s, or any type of outdoor fire should be accompanied by a fire extinguisher and a shovel.
..Don’t forget to leave extra water and shade for your pets as this heat wave continues.
..Have a good Day! Enjoy the nice mountain weather!!
