Good Morning.
Today’s forecast will be much the same as yesterday. A few high clouds, light and variable winds and warm temperatures. But, change is on it’s way. For today and Saturday, we will continue to be under a slowly weakening Ridge of High pressure. Gusty winds will develop mostly in the late afternoon and evening hours, increasing through Monday.
Along the Coastal areas, Fog and low clouds will increase as well over the next couple days eventually making it to the IE and along the Rim by Sunday. This morning, the Fog is being held close to the Coast. The IE is clear.
Saturday a slow cooling trend will begin. Temperatures across the mountain will fall by around 3-6*, and for Sunday, a couple more degrees of cooling is expected. High clouds will thicken on Sunday as a Cold Core Cut Off Low approaches SoCal.
By late Sunday afternoon, we will see a slight chance for a sprinkle or two. This is when things get tricky, Sunday night and Monday, we will be in the opportunity spot for Thunderstorms and or rain showers. We will be located in the Left front quadrant, or NE corner of the Cut Off Low at that time. CAPE, LI, and K index levels will be in the weak to moderate levels for Thunderstorm activity across the local area.
Monday, we will have a thick cloud cover with a saturated air mass overhead. So Nancy, you should see the showers you have been asking for. Rainfall totals will be variable but I would expect at least .25″ to .50″. Due to the unstable air mass these estimates will vary by area. Big Bear as always will have the best chances for T-Storms. Snow levels will be around 9000′, but due to the unstable air mass, Hail could fall to the 6000′ level during Thunderstorm activity. Also, outflow winds from any T-Storms that do develop could gust from 20-40mph in localized areas.
Cold air aloft and warm air at the surface makes for a good match for T-Storms or convection on Monday. Then for Tuesday, a trailing Trough will move through helping to keep temperatures in check.
After that Trough passes, we will begin another warm up through the weekend as High pressure returns to the West. Enjoy!
Have a great day and week ahead. That’s it for today. Thank you for joining me @ lakegregoryweather.com
