Area Forecast Discussion
National Weather Service Sacramento CA
213 PM PDT Mon Apr 6 2020


.Synopsis...
Cool and unsettled weather continues with scattered showers and a
few thunderstorms through this evening. Dry weather and warming
temperatures expected through mid-week. Normal than average
temperatures expected by late week.

&&

.Discussion...
The deep low that brought significant precipitation to NorCal this
weekend continues to move southward off the coast today. Showers and
isolated storms are already noted in the northern San Joaquin Valley
early this afternoon making their way back into the area. This rain
will move into the southern Sacramento Valley bringing additional
showers and storms through this evening, mainly south of I-80.
Models indicate up to roughly 300 J/kg of CAPE this afternoon, and
any thunderstorms that develop may produce small accumulating hail
and heavy rain.

Some light wrap around precipitation is possible in the northern
mountains and Sierra overnight into tomorrow with only a few inches
of additional snow expected with this activity. The upper low makes
its way towards the Central Great Basin Wednesday into Thursday, and
a brief period of breezy north winds may be seen Wednesday. As EPac
high pressure builds in behind the departing low, above normal
temperatures and dry weather is expected the rest of the week.

&&

.EXTENDED DISCUSSION (Friday THROUGH Monday)...
Eastern Pacific high pressure builds in across NorCal late week
and into the weekend. The strengthening ridge should easily
bolster temperatures well into the 70s over the Valley with even
some lows 80s squeezing into the northern Sacramento Valley.
Overall, expect daily highs to run around 5 to 10 degrees above
average accompanied by mostly sunny skies and relatively light
winds. BRO/eh
