area forecast discussion

842 am pdt Sun jun 16 2019

Synopsis A few degrees of warming is expected for mainly inland
areas on Sunday as high pressure begins to build near the west
coast. More widespread and significant warming is forecast for
Monday and Tuesday as high pressure strengthens and onshore flow
weakens. However, warming at coastal areas will be limited due to
persistent onshore winds. Seasonable temperatures, along with
areas of night and morning low clouds, are forecast through the
end of next week.

Discussion As of 08:42 am pdt Sunday... June gloom is in full
effect the morning. Morning visible satellite shows a very deep
marine layer across much of the bay area, including into the
sacramento valley. The marine layer is so deep and moist that
widespread drizzle is being reported. Over the last 12 hours
automated gauges show the drizzle was heavy enough to accumulate
a few hundredths in the hills. Did a quick update early this
morning to include more drizzle for the morning hours and extend
cloud coverage. Given the deep nature marine layer, burn off will
be slow going this morning. Do some expect some afternoon sunshine
across the interior, but lingering clouds will remain at the
coast. No other updates were made to the near term forecast.

Next weather item of focus will be the warming trend and building
high pressure. The work week will be warmer than the current
weekend, but do want to emphasize this warm up will not even come
close to the heat wave from a week ago.

Prev discussion As of 2:22 am pdt Sunday... The fort ord profiler
indicates a marine layer depth of around 2000 feet, and ir
satellite imagery shows coastal stratus has extended well inland
filling inland valleys. Ceilings at area airports range from a few
hundred feet to 1400 feet. Current temperatures are generally
similar to those from yesterday at this time with readings in the
lower 50s to around 60. Highs today are forecast to be a little
warmer than yesterday's as high pressure aloft begins to build
over the eastern pacific and onshore flow weakens. Highs today are
forecast to range from the 60s at the coast to the 70s and 80s
inland.

The warming trend will continue early in the week as the upper
ridge over the eastern pacific builds eastward over california.

The building high will compress the marine layer, resulting in
less inland development of low clouds and fog by Monday morning,
and especially Tuesday morning. The most significant warming on
Monday and Tuesday will be across inland areas where some
locations could warm to the lower 90s. As a light onshore flow
and marine layer will continue, coastal areas shouldn't see too
much warming.

Tuesday and Wednesday will likely be the warmest days this week.

Medium range models indicate an upper trough dropping inland to
our east during the second half of the week, pushing the ridge
back offshore. This would bring cooler temperatures back to inland
areas, but remaining slightly above seasonal normals.

Aviation As of 5:05 am pdt Sunday... Onshore flow and extensive
marine layer stratus has reached well inland. Morning mixing out
of stratus will be slow going, stratus then extending back inland
tonight and Monday morning.

Vicinity of ksfo... Ifr-MVFR cig, clearing by 21z today. West wind
increasing to 15-20 knots by 22z. MVFR cig returning mid to late
evening.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Ifr CIGS through late morning, partial
clearing in the afternoon. Ifr CIGS returning in the evening.

Marine As of 10:39 pm pdt Sunday... High pressure off the
northern california coast will keep strong northwest winds
confined to the northern waters through Monday. Light winds can be
expected over the central and southern waters.
