gusting above 20 kts at ksuu, but the increase in cloud cover is
resulting in milder temperatures across most of the area.
Satellite imagery shows the short-wave presently off the norcal

norcal will be under the influence of a longwave trough axis
overhead through the weekend. This will continue below normal
temperatures. No precipitation expected. By the end of the weekend
into early next week, the trough axis pushes east into the Great

in temperatures and more northerly flow. Jclapp/ceo
