735 pm edt Sat aug 24 2019

A cool wedge of high pressure will linger across the region into
Monday. Warmer air and increased shower chances are on tap ahead of
an approaching cold front Tuesday and Wednesday. Drier weather is
possible behind the front to end the work week.

Near term through Sunday
As of 700 pm edt Saturday: widespread low clouds have kept
temperatures down through the evening, so have made several
adjustments to hourly t td, but for now no changes to overnight
lows. Precip has really stayed mainly in the mountains, so have
lowered pops elsewhere through the evening and overnight hours.

Seeing some anchoring of showers over the terrain, so will continue
to monitor that through the night. Other updates are all for
aviation parameters.

Otherwise, the broad sfc high presently centered just north of the
great lakes will continue to build over the NE CONUS thru the
period, aided by confluence downstream of an upper ridge.

Unseasonably robust cool-air damming will persist over our area as a
result. As such, any thunder lightning should be relegated to our
southern fringe zones and maybe our western-most mountains. As is
typical in a wedge pattern, temps will be tricky to fcst. I lowered
high temps for today to better reflect the current values and an
overall lack of sfc heating seen so far. Low-level flow will veer
slightly tonight, making upslope forcing over the blue ridge a bit
more of a factor for wnc, and implying a bit better isentropic lift
throughout the area. This should be enough to maintain abundant
stratus across most of the fcst area. Low temps will be near normal
overnight as the cool airmass will be offset by good cloud cover.

Short term Sunday night through Tuesday
As of 240 pm edt Saturday: blocking pattern over eastern north
america weakens on Monday as the upper low off the new england coast
moves north and upper ridge along the east coast weakens. This
allows a dampening upper trough to move east into the area through
the period. At the surface, the cold air damming wedge remains in
place but slowly weakens Monday as the potential tropical system
moves north off the carolina coast. Expect continued cool conditions
but with a slow warming trend. Upslope flow will help generate
showers over the western cwfa but precip will be light. Better
chances of precip develop Tuesday as forcing increases with the
trough. Even then, the better chances will be across the western
cwfa. The cad wedge continues to weaken Tuesday but doesn't
completely erode. Highs will only be slightly warmer.

Long term Tuesday night through Saturday
As of 100 pm edt Saturday: temperatures are slated to rebound back
to values closer to climo on Wednesday as return flow increases
ahead of encroaching S WV and attendant sfc bndry. The latest
medium range blended solutions continue to advertise greatest cvrg
of showers acrs the mountains. In the wake of Wednesday's frontal
passage, we are expecting an influx of deep layer dry air on
Thursday which will probably warrant the removal lowering of the
inherited token slight chance pop. Temperatures are expected to be
close to the late august climo, although blyr dwpts should take a
downward tumble. Regionally, by the end of the work week, greatest
shower coverage should be closer the coast near the stalled
baroclinic zone. A very weak llvl ridge axis and weak mean flow
regime is progged atop cwfa on Friday, as mean rh marginally
increases. At this point, senisble weather should be limited to
small and or slight increase in showers, especially in the piedmont,
nearer to the better moisture.

Aviation 00z Sunday through Thursday
At kclt and elsewhere: widespread MVFR at TAF time, with some
pockets of ifr as well as some lowVFR, and this will continue
overnight with only some minor fluctuations as the cad remains in
place. Should see some slow improvement during the day tomorrow, and
kand and kclt could see lowVFR through the afternoon. Some
indications of lowering again tomorrow night but will reevaluate
that with later tafs. Steady NE winds 5-10kt with low-end gusts
possible off and on through the period.

Outlook: expect improving conditions going into Monday as drier air
moves in, however moisture and another frontal system move back in
by midweek with associated restrictions possible again.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
