Issued Zones:  LA Deserts … Kern Desert … Kern Mountains Lake Isabella but NOT Tehachapi … High Desert … Las Vegas Metro … Hemet Valley …

Site:  Southern California Weather Force has issued a Thunderstorm Watch effective now through the evening …

Date:  8/19/20 at 8:20am PT

Forecast: An area of vorticity coming through the Morongo Basin this morning will pull northward over the day as the ridge migrates.  This should allow dry air advection behind it and now my thoughts are it will lessen the debris clouds and push up instability in the watch area.  Outflow from the Metro High Desert storms will surge northwestward and affect the AV to Ridgecrest areas. 

This watch includes the drive on I-15 between Barstow and Las Vegas and does also include near the Las Vegas Metro, but mostly state-line/jean …

I did highlight the Hemet Valley areas just in-case the storms in the Riverside Mountains push off.  It will not be anywhere near as severe as yesterday though, but you are close enough to warrant a watch highlight …

NOTE: I am NOT allowing new sign-ups paying for the SCWF alert system at this time. I am redoing the system over the Summer and offering free service till October 1st. This is because this Summer is either close… or keep open come the next storm season due to a post COVID-19 economy.
