little more expansion of cloud cover for today/this evening as
vorticity maximum wraps through our forecast area. Radar and satellite data
look a bit more convective than anticipated. Taking a look
outsite...lots of virga present just to our southwest which is
right where the small convergence area depicted on radar is. All-
tilts show base of cloud are about 8-10kft. Kept any chance of
accumulating precipitation to the Sierra foothills and higher but did add
mention of sprinkles to the central and southern San Joaquin
few clouds and above normal temperatures are expected through
Monday. Afternoons will be warmest Sunday and Monday and will
approach record levels in the San Joaquin Valley and nearby
foothills. A weak low pressure system will approach Tuesday pushing
temperatures back down but still remaining above normal.
winds will be decreasing across the region this afternoon and by 03z
will be primarily terrain driven. Non impactful winds expected
Thursday all areas. Few to scattered clouds near 10kft and localized MVFR
