A weak ridge is over the area today with a very weak shortwave
moving through central California today. The models are trying to
indicate some showers near the crest from around Alpine County
southward as a result of this shortwave. The shortwave moves to
the east by Monday and an approaching low pressure system off the
Pacific Northwest coast will gradually break down the ridge and
replace it with cyclonic flow aloft.
On Tuesday that weak system will pass by to the north and may
bring a few showers over the far north end of the valley and
mountain areas north of I-80. Areas to the south will be
remaining dry but much cooler by 5 to 15 degrees with the greatest
cooling occurring in the mountains.
Another shortwave will move through the area on Wednesday but the
greatest impact looks to be keeping temperatures cool over the
region. Some showers look possible over the northern areas.
.Extended Discussion (Thursday through Sunday)
High pressure will return Thursday into Friday and could result
in another period of breezy northerly winds. Longer range models
are hinting at a potentially stronger and colder system moving
through Northern California next weekend. There is still plenty of
model uncertainty with regards to timing and intensity of that
system, but we`ll pay close attention to model trends.
VFR conditions will continue the next 24 hours. Mostly northerly
winds below 10 kts.
