Quick Wednesday Evening Update:
A dry cold front is draped across Southern California. As of 3:30pm, the front was located along a line from near Las Vegas and to the southwest through northern Orange County andand continuing off the coast. High cirrus clouds are found along and to the east of the front, with mostly clear skies behind the front, except for some low clouds banking up along the Southern San Joaquin Valley near Bakersfield.
The cold front is dry, but is accompanied by a wind shift and a cooler airmass will filter into our area tonight, and remain here for several days.
As of 3:30pm, gusty WNW winds were still isolated to along I-10 from Whitewater and east into the Sky Valley area, with gusts from 30-45 mph. The winds have not yet spread further south and east into Palm Springs, Cathedral City, Rancho Mirage, Palm Desert or Indio. This should change over the next several hours, with winds becoming more widespread and possibly being accompanied by blowing dust. Some lesser gusts to near 30 mph have also spread into the Yucca Valley and Joshua Tree areas.
WNW winds will likely remain strong in the normally windy locations closer to I-10, with occasional gusts possible in the more populated areas through at least midnight.
Winds will likely shift to the north later tonight, with some areas remaining calm, and others experiencing even stronger gusts, possibly hitting 55 mph in some localized areas at times.
Thursday will likely continue to display occasional strong winds from the north or northeast, and high temperatures will likely only reach the low-mid 70's.
Winds should drop Thursday night, and temperatures will drop into the 40's. The high deserts will likely see the coldest night of the autumn season, with many areas below freezing near Yucca Valley Thursday night.
Gradual warming Friday and Saturday for stunning fall weather, before another weak system approaches late Sunday or Monday. A slight chance of rain may even accompany this system, with clearing weather expected again Tuesday and Wednesday.
