Synopsis
Pattern change will lead to significantly cooler temperatures and
a chance of showers and thunderstorms late this evening into
Monday. Another system could bring additional showers by midweek.

Dry weather and warm temperatures return late this week.

Discussion
An upper level low pressure system is approaching the west coast
this afternoon, bringing cooler temperatures to interior norcal.

High temperatures today will peak around 5 to 10 degrees cooler
than yesterday with valley temperatures in the mid to upper 80s
and mountain temperatures in the 60s and 70s. Winds have begun to
increase this afternoon with gusts up to 20 to 25 mph, locally
higher over the delta region, observed across the valley and
sierra.

Southwesterly winds will increase in advance of the trough. Gusts
up to 30-40 mph will be possible near the sierra crest this
afternoon and Monday. This could result in a brief period of
enhanced fire weather conditions across the sierra today, though
the expected precipitation should help mitigate fire weather
concerns.

Deterministic and ensemble guidance indicate rain showers
spreading into shasta county and the coastal range late this
evening, then reaching the i-80 corridor around mid morning Monday
into the early afternoon hours. Forecast soundings indicate the
potential for isolated thunderstorms on Monday, generally from
sacramento northward including the valley and higher terrain. At
this point, the most likely timeframe for convection appears to be
late morning into early evening. Forecast rainfall totals are
around one tenth to half an inch, and up to one inch over the
mountains. Locally higher amounts are possible if storms develop.

Snow levels should remain relatively high as bulk of precipitation
moves in, but could briefly lower to around 6500 ft in
convection. Coolest temperature readings of the week are expected
to occur on Monday, with daytime highs as much as 10 to 25 below
average.

The upper-level trough is forecast to shift east of the state by
early Tuesday, ending precipitation threat across interior norcal.

However, this dry period should be short-lived as another system
takes aim at the west coast by midweek. At this point, it appears
that precipitation will approach the northwestern portions of the
forecast area by late Tuesday night early Wednesday, with best
chances over the foothills mountains. In addition, guidance
suggests the potential for thunderstorm development at least over
higher terrain Wednesday afternoon. Below normal temperatures
will continue on Wednesday, with valley highs in the mid 70s to
low 80s.

Extended discussion (Thursday through Sunday)
On Thursday morning, an upper trough will be in the process of
exiting the region while it reaches the desert southwest by the
evening hours. Some lingering mountain showers are possible
although these should become more scattered in nature by later in
the day. Deep-layered northerly flow will follow the trough
passage with such conditions continuing throughout Friday. A brief
period of height rises are likely for Saturday although some
ensemble members show a trough nearing the west coast late next
weekend. Ensemble means remain at odds so will maintain a warming
trend in the forecast. From Thursday to Sunday, highs will likely
rise by around 10 degrees which takes valley temperatures to near
90 degrees. ~bro
