Warm and fairly dry weather will continue early this week. Weak
systems may bring a few intermittent showers to the mountains
today into Wednesday. Another chance of precipitation possible
next weekend.


Temperatures today continue to warm and should top out in the low
to mid 80s for the valley and 60s to lower 70s in the mountains.
Some temperatures will come close while others will reach record
levels today. Below are some of the record temperatures for today
with the current forecasted highs.

A weak ridge is over the area today with a very weak shortwave
moving through central California today. The shortwave has moved
far enough inland with no signs of any showers popping up along the
crest so have removed any mention of them. 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 and up valley flow.

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 transition to a cooler and unsettled pattern next
weekend. The GFS and GEM are a bit more bullish with the initial
wave of precipitation than the ECMWF for next weekend. All are
suggesting a colder and wetter system setting up for the following
week. We`ll be paying close attention to model trends.




VFR conditions will continue the next 24 hours. Generally light
north winds will become south Monday afternoon.
