...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 1220 AM PDT Mon May 6 2024

Despite the chilly start to the day, a warming trend will lead to
above normal temperatures by Thursday. Once the warm weather
arrives, it should be pretty persistent through mid month.

&&

.SHORT TERM...
(Today and tonight)
Issued at 1220 AM PDT Mon May 6 2024

The satellite image is pretty clear tonight, with just a few
pockets of orographic clouds in the mountains. These clear skies
will allow enhanced radiational cooling before the sun comes up.
Expect inland temperatures to drop into the low 40s with a few
pockets of upper 30s. Mostly clear skies will prevail through the
morning, allowing temperatures to recover quickly after sunrise.
A weak disturbance will bring some cloud cover and moderate NW
winds back this afternoon and evening.

.LONG TERM...
(Tuesday through Sunday)
Issued at 1220 AM PDT Mon May 6 2024

A upper level ridge will set up camp this week, keeping warm and
dry weather in the forecast for the foreseeable future. Thursday
and Friday look like the warmest days of the week, with coastal
highs in the upper 60s and inland highs in the mid-80s. There is
a minor HeatRisk for inland areas beginning Wednesday and
persisting through the forecast period. This will cause concern
for individuals who are extremely sensitive to heat, especially
when outdoors without effective means of cooling or adequate
hydration. With the sharp change from the cool temperatures this
weekend, this week may catch some folks offguard.

An inland ridge will cause offshore flow to develop mid week,
decreasing the relative humidity into the 20-40% range. The
strongest winds will be in the Vaca Range of Napa County, with
gusts up to gale force Wed night-Thu morning. With fuel moisture
still above average, this shouldn`t be a major fire weather
concern, but will act to dry things out as the fire season
approaches.

The Climate Prediction Center forecast shows above normal
temperatures are likely for the next 2 weeks which will likely
trigger the typical summer pattern of coastal stratus after the
offshore wind event ends this weekend.
