area forecast discussion
national weather service san francisco bay area
1032 pm pdt Thu sep 20 2018

Synopsis Cooler temperatures are expected near the coast and
in some valleys on Friday, but most inland areas will remain very
warm and dry. Cooling is expected region-wide over the weekend as
onshore flow increases, but temperatures are forecast to remain
near or slightly above seasonal averages. A renewed warming trend
is then likely during the first half of next week as high pressure
builds near the west coast and offshore flow potentially
develops.

Discussion As of 9:00 pm pdt Thursday... Dry northerly flow and
high pressure aloft combined to produce a very warm and dry day
across inland areas today. Afternoon highs were in the low to mid
90s across most inland areas. Brief light offshore flow near the
surface managed to bring some of that warm air locally to the
coast. Downtown san francisco briefly warmed above 80 and
downslope winds warmed santa cruz and big sur to 93 and 89
respectively. Gusty north winds in the hills late last night and
this morning increased fire danger, but winds have since decreased
and are expected to remain light through Friday. The red flag
warning for bay area hills was allowed to expire at 5 pm this
afternoon (see fire weather discussion below for more details).

Skies remain clear this evening across our entire region.

Temperatures near the coast and in the valleys will cool off
nicely overnight due to clear skies, very dry air, and nearly 12
hours of darkness as we approach the autumnal equinox. But
temperatures in the hills will remain warm overnight and very dry
conditions will prevail there as well. Fortunately, winds are
forecast to remain light overnight.

The NAM wrf models continue to forecast a southerly surge late
tonight and Friday, although the onset of the surge has been
delayed from what these models had forecast yesterday. A later
onset of a southerly surge appears reasonable given that satellite
currently shows all marine low clouds fog remains south of point
conception. Based on latest model data, fog and low clouds will
begin to develop northward along the monterey county coast late
tonight and then surge northward up along the sf bay area
coastline on Friday. This does not look like a classic southerly
surge event and so confidence is not all that high that it will
develop as forecast. A forecast update early this evening included
delaying the development of fog and low clouds on the coast from
santa cruz county northward from late tonight until tomorrow.

With low level flow forecast to turn southerly along the coast on
Friday, expect cooling in most coastal areas. Santa cruz could be
as much as 20 degrees cooler tomorrow compared to today if
southerly winds develop as expected. Some coastal valleys will
also experience cooling on Friday, such as the northern salinas
valley, and north bay valleys. However, the inland valleys and
hills will remain very warm and dry on Friday.

An upper trough is forecast to move inland across the pacific
northwest and far northern california over the weekend. This will
result in at least modest cooling across our entire region on
Saturday and Sunday as onshore flow increases. Locally gusty
westerly winds are forecast to develop, especially by Sunday
afternoon. Compared to yesterday, the models have increased the
magnitude of cooling over the weekend and most model guidance now
indicates temperatures cooling back to near seasonal averages by
Sunday.

Confidence is growing that our region will see another robust
warming trend early next week as an upper ridge amplifies off the
west coast. Latest models indicate we could see a brief period of
gusty northerly winds in the hills at the onset of the warmup,
primarily on Sunday night and Monday morning. Will need to monitor
this closely for potential fire weather concerns. Otherwise,
generally light offshore flow is forecast from Monday afternoon
through midweek. Widespread 90s are forecast for inland areas by
Tuesday and Wednesday and 80s look to be common near the coast on
those two days. The forecast update early this evening included an
increase in high temperatures across our region for the first half
of next week.

Aviation As of 10:30 pm pdt Thursday... The offshore flow has
diminished but has left a dry airmass over the area that will keep
clearVFR conditions through at least Friday morning. Southerly
flow develops along the coast Friday which may start to push
stratus up the coast from southern california Friday night.

This is becoming more likely as satellite image shows increasing
low clouds along the coast from sba south. Low CIGS could reach
the mry bay area Friday evening.

Fire weather As of 8:50 pm pdt Thursday... North winds in the
hills decreased this afternoon and remain relatively light this
evening. The red flag warning for the north bay mountains, east
bay hills, and santa cruz mountains was allowed to expire at 5 pm
this afternoon. A warm and very dry airmass will remain over
inland areas through Friday and relative humidity recoveries in
the hills tonight are expected to be very poor once again.

However, winds are forecast to remain light overnight and through
the day on Friday.

Gradual inland cooling is forecast over the weekend as onshore
flow increases. Locally gusty westerly winds are expected by
Sunday afternoon. A renewed warming trend is then likely during
the first half of next week with inland temperatures forecast to
warm back into the 90s by Tuesday and Wednesday. Models indicate
the potential for moderate northerly (offshore) winds in the hills
on Sunday night and Monday morning and then light offshore flow
from Monday afternoon through midweek. Will need to monitor the
forecast for early next week closely for the potential for
stronger offshore winds.

Marine As of 10:28 pm pdt Thursday... Winds will decrease
overnight and become light southerly along the coast as a thermal
trough shifts offshore. High pressure will rebuild over the
eastern pacific Sunday resulting in the return of northwest winds.
