Forecast

June 17, 2021/report

June 17, 2021

Strong upper level high pressure over the Four Corners region has expanded westward over California and well off shore.  Temperatures this morning on the valley floor are ranging from 4 to 6 degrees warmer than 24 hours ago.  The air above the valley floor is down right hot.  Grapevine Peak at around 4,500 feet is reporting 81 degrees as of 6:00am, Sandberg at 4,100 feet was reporting 84, and even way up at Bear Peak at 8,200 feet the temperature was 71 degrees…warmer than most valley locations.

 

The marine layer, as you might imagine, has been crushed and stands at 500 feet.  Very hot weather will begin today, peaking Friday and Saturday as the high reaches its pinnacle.  Bands of mid and high level clouds based at above 15,000 feet are rotating  northward due to the clockwise flow around the high.  Models indicate that intense daytime heating will result in short lived isolated thunderstorms over the high Sierra.  One model actually shows a cell or two over the Kern County mountains.

 

The pattern will finally begin to change Sunday night and Monday, although triple digits will likely last through Tuesday.  A weak low center will develop off the northern California coast, turning the winds aloft to west/southwest.  At the surface, the marine layer will rapidly deepen, spilling initially through the Delta then other gaps and passes through the Coast Range.  For now, it appears mid to upper 90s are likely for Wednesday with possible low to mid 90s Thursday.

 

Forecast: Mostly clear and extremely hot through Sunday. Mostly clear and hot Monday.  Mostly clear Tuesday through Thursday with a cooling trend.

Two Week Outlook:  June 21 through June 29:  this model shows a wide ranging high pressure system over the western US, resulting in above average temperatures and dry conditions.

 

June:  This model is indicating a ridge of upper level high pressure will be more dominant over the Desert Southwest and, to a lesser extent, California, resulting in above average temperatures for the month with the usual dry conditions prevailing.

 

June, July, August: This model mimics the pattern of recent years, indicating high pressure over the Desert Southwest being the most dominant feature, resulting  in above average temperatures.  Theoretically, this pattern blocks monsoonal moisture from moving northward.  Typically, there’s little to no precipitation anyway, and that will be the case this summer.

 

Winds Discussion:  Winds during the afternoons and evenings will be generally out of the northwest at around 8 to 15 MPH.  Winds during the night and morning hours will be generally at or less than 8 MPH with local gusts to 20 MPH afternoons and evenings along with periods of near calm conditions through Sunday.

 

Afternoon Dew Points Today:  Low to mid 50s. Kern:  Mid to upper 40s.
