Sharp, MD

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure remains offshore overnight as a cold front
approaches from the west through Tuesday morning. The front
will cross the region Tuesday evening, with high pressure
building in for Wednesday and Thursday. A little more unsettled
for the weekend with an upper trough lingering just west of the
region.

Near term until 6 am Tuesday morning
As of 900 pm edt Monday...

early evening analysis showing a weak pre-frontal trough just
west of the local area. Numerous showers and thunderstorms
fired up along this boundary just to the w-nw of the local area,
resulting in iso to widely sct t-storms sliding across the area
earlier this evening, mainly across the western half of the
local area. Storms have greatly diminished with loss of heating
over the past couple of hours, and a few lingering showers
mainly over the va piedmont through the next few hours.

Otherwise, mild and humid overnight with partly cloudy skies.

Lows generally in the 70s.

Short term 6 am Tuesday morning through Thursday
As of 300 pm edt Monday...

the cold front over the ohio valley great lakes will move
through the middle atlantic late Tue aftn into Tuesday night.

There is a suggestion from both the NAM and GFS that there will
be a split of precipitation over the area with an area of
showers storms across the north associated with a weak low
developing along the front, with another area further se
associated with the better instability. This may leave the far
southern piedmont without much in the way of precip tomorrow.

Cannot remove pops from this area, but will lower to chance
pops. Despite MLCAPE values close to 1000 j kg, the deep layer
winds are generally 30 kt or less, so severe weather is not
expected. Again, could be locally heavy rainfall given the high
precipitable water values, but not excessive as the frontal
speed will be allowing the storms to move along to the se.

Drying quickly moves in from the NW Tue night into Wed behind
the front as broad high pressure extends from the great lakes
into new england and the middle atlantic. Wed Thu should be
pleasant days with mostly sunny skies and lower humidity. Highs
in the mid-upr 80s during the day, with lows dropping back into
the 60s at night. Would not be shocked to see upper 50s in the
piedmont Wed night.

Long term Thursday night through Monday
As of 300 pm edt Monday...

the weekend into early next week looks somewhat unsettled as a
strong upper trough over the northern plains dives into the ohio
valley for the weekend and closes off. This allows for the weak
short wave ridge over the area Friday to move off the coast
leading to south- southwest flow across the area. Although
showers storms cannot be ruled out on Saturday, it seems like if
there would be a dry day it would be Saturday with the low
still well to the NW leading to somewhat downslope flow.

However, Sunday into Monday will be unsettled as the upper low
slowly moves east yielding periods of showers storms. No major
tropical connection so rainfall is not expected to be excessive.

Temps generally close to normal for this time of year -
generally in the upper 80s lower 90s during the day and upper
60s- mid 70s at night.

Aviation 02z Tuesday through Saturday
As of 730 pm edt Monday...

have keptVFR conditions in place through the 00z TAF period.

Basically not expecting anything more then sct-bkn mid high
clouds through early afternoon Tuesday. A cold front approaches
from the west by Tuesday afternoon leading to widespread shwr tstm
development into Tuesday night. While severe wx is not
expected, localized MVFR or ifr conditions will be possible in
the heaviest shwrs tstms late tues aftn eve. Due to the late
arrival of said pcpn, have generally kept dry conditions in all
but kric thru the period. SW winds will become gusty (~20kt)
ahead of the cold front tues afternoon.

Outlook:
the cold front passes through Tuesday night, leading to high
pressure andVFR conditions Wed into thu.

Marine
As of 1000 pm edt Monday...

high pressure off the SE us coast will continue to slowly edge
away from the coast overnight. This should keep southerly winds
going across the waters at 10-15 kt, and possibly up to 20 kt
across the northern coastal waters. Expect waves to kick up to
around 2 ft on the bay and 3-4 ft on the coastal waters. Conditions
should remain just below SCA levels.

The cold front will move across the waters later Tuesday into
Tuesday evening. The southwest flow will continue, but the wind
should not be as strong as tonight. Behind the front should see
a good surge of northerly to northeasterly flow late Tuesday
night into Wednesday morning. Again winds will be borderline for
sca conditions. By Wed afternoon, the surface high should have
built into the region and winds will begin to diminish. This
area of high pressure will remain in control of the weather into
the day on Friday, before another system arrives for the weekend
with unsettled conditions.

Kdox radar is inoperable due to a failure of the motor. Earliest
return to service is Wednesday.
