.SYNOPSIS...
Deep layer ridging will bring warm and dry conditions into next week
with record highs in jeopardy most days through Tuesday. A cold
front will cross the region Tuesday night into Wednesday bringing a
period rain to the region. High pressure builds in from the west
behind the front with cooler and drier air moving in for the second
half of the week.
&&
.NEAR TERM /THROUGH TODAY/...
Warm, mostly sunny skies and near record high temperatures are
expected today in a regime of deep layer ridging.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM MONDAY/...
Aside from some valley fog tonight, we are looking at another
relatively warm night along with near record highs in the 80s on
Monday.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Well above average temperatures will persist one
more day on Tuesday with near record high temperatures possible once
again. A strong cold front and trough of low pressure will then
cross from north to south Tuesday night into Wednesday morning,
bringing our best chance for widespread measurable rainfall. Rain
looks to end quickly on Wednesday morning but some lingering showers
will be possible, especially across the north and mountains. Sharply
colder temperatures can be expected with daytime highs around 15-20
degrees cooler than those of Tuesday. Even colder air arrives for
Thursday with highs only into the 50s to lower 60s from north to
south. Widespread frost/freeze conditions are then likely Thursday
night with lows near or below freezing in many locations, especially
away from the immediate coastline and urban centers. A slight
moderating trend is then likely through the remainder of the week
and weekend but daytime highs will only warm to around seasonable
averages.
&&
.AVIATION /04Z SUNDAY THROUGH THURSDAY/...
Short Term...Similar VFR conditions will continue through
Monday. VFR during the day with fog possible late tonight into
early Sunday morning and again Sunday night at LEB and HIE. RKD
may see marine fog Sunday night, but confidence is low on this
at the moment.
Long Term...Other than perhaps some valley FG at mainly KLEB/KHIE
on Monday night, VFR will be common through the day on Tuesday with
S-SW flow. A cold front will bring RA to all sites Tuesday night-
Wednesday morning along with lower ceilings and restrictions.
Conditions improve later Wednesday with NW flow, although MVFR
restrictions may linger at KHIE with upslope flow. Mainly VFR
conditions are then likely through the remainder of the week.
&&
.MARINE...
Short Term...SCA conditions are not expected through Sunday night.
Southerly flow this afternoon will become more light and variable
tonight and early Sunday. Prevailing south to southwest flow then
takes over Sunday afternoon through Sunday night with high pressure
centered to the south and east of the waters. Gusts may approach
SCA levels Mon afternoon.
Long Term...Southwesterly wind gusts may approach 30 kts Monday
night and Tuesday ahead of a cold front before becoming
northwesterly on Wednesday behind the front with gusts remaining
around 25-30 kts. Seas of 1-3 ft can be expected in the bays
with 4-6 ft across the outer waters. Winds and seas then will
likely lower through the remainder of the week as high pressure
builds over the waters.
&&
.CLIMATE...
Temperatures will be high enough to possibly challenge records
the next few days as an anomalously strong 580+dam ridge builds
over the area by Monday. Here are some of the records to watch.
