Broomes Island, 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
A warm front moving through central virginia and southern
maryland this afternoon will continue moving northward into
this evening. At the same time, low pressure will press eastward
from the eastern great lakes. A cold front associated with this
low will drop southward on Sunday, passing through region
Sunday night. Canadian high pressure will return through Tuesday
before migrating offshore during the middle portion of next
week.

Near term through tonight
A warm front snakes across central virginia, finally making
progress northward as earlier forecast. However, clouds have
stubbornly stuck around much of the day east of the blue ridge,
keeping conditions cooler and limiting the instability to this
point. As the warm front lifts northward, we are starting to see
breaks in the clouds that have remained cloud covered much of
the day. Low pressure over the lower eastern great lakes is
making its track eastward, with a midlevel trough nearing our
region from the west. This has helped nudge the aforementioned
warm front northward through the cwa. Support aloft in the form
of shortwave energy and jet dynamics will aid in providing lift
across the area this afternoon and early evening for shower and
thunderstorm development.

Areas to the south and east of the i-95 corridor, and likely dc
southward will have the most favorable environment for any
severe storms as the best moisture, instability, and lift will
reside here. MUCAPE values of 1000-1500 j kg and SBCAPE nearing
2000 j kg, as well as 0-6km shear values of 30-40kts will be
supportive of strong to severe storms, mainly along and east of
the i-95 corridor. Can't rule out the occurrence of large hail
and or a brief tornado, particularly over the areas that see
the greatest destabilization and storms are able to interact
with the warm front moving northward. A slight risk of severe
storms covers areas along and east of the blue ridge, extending
over to the bay.

Activity should wane this evening as the trough pivots off to
the northeastward away from the region and flow aloft turns more
zonal, with even some weak ridging building overhead towards
morning. Lows tonight will range in the middle 60s to near 70
degrees. Could see some scattered occurrences of fog early
Sunday morning with ground moisture where precipitation occurs
today, but coverage isn't expected to be widespread.

Short term Sunday through Monday night
As the low moves eastward from the great lakes on Sunday, a cold
front will drop southward in to our region, but not likely
passing through the area until Sunday night. There will be a
weak shortwave trough passing to our north, and the best lift
looks to remain north of the mason dixon as well. Still think we
could see some shower and thunderstorm activity Sunday afternoon
as a result, triggered by diurnal heating. Highs on Sunday will
be quite warmer than today, extending in to the upper 80s to
near 90 degrees, and ample humidity in the air. Activity will
wane Sunday evening and that front will push through overnight
with little fan fare, just a subtle shift in the wind direction
towards Monday morning. Lows Sunday night again in the middle
60s to near 70 degrees in the cities.

Canadian high pressure will emerge on Monday, filtering in
cooler and drier conditions area wide. This will promote much
more comfortable temperature and humidity levels, with near
normal highs lows Monday and Monday night. Dewpoints will be on
the decline falling through the 60s during the day on Monday,
reaching the 50s overnight Monday. No threat of precipitation
Monday and Monday night.

Long term Tuesday through Friday
Canadian high pressure continues to build into the region on
Tuesday, resulting in sunny skies and no rain. Northerly wind should
keep temperatures below average, with highs expected to be in the
low 80s. The humidity will also be much lower Tuesday.

High pressure shifts off the east coast on Wednesday, starting a
gradual warming trend for the rest of the week. With the flow
turning more southerly on Wednesday, more moisture will be advected
into the region, which should allow for some afternoon
thunderstorms. Additionally, a cold front associated with a canadian
low pressure system will move across the region Wednesday night into
Thursday morning. This will bring yet another chance for some
showers and thunderstorms in that period. High temperatures should
be back into the mid 80s.

Some lingering showers and storms will be possible on Thursday, as
the front continues to move out of the region. High temperatures
will approach 90, as this front doesn't appear to bring a large
temperature drop along with it.

The front appears to stall somewhere near the region on Friday, but
appears to be relatively weak. This could provide a focal point for
some thunderstorm development Friday afternoon as well, but
otherwise expecting a dry day. High temperatures will be into the
lower 90s.

Aviation 19z Saturday through Thursday
MVFR conditions prevailing this afternoon at all terminals as a
warm front this northward through the area. Scattered showers
and thunderstorms developing to the west will continue moving
eastward, impacting the terminals into early evening. Some
storms could be strong to severe, with gusty winds being the
primary threat. Outside of convective activity, southwest
breezes at 10 knots or less are forecast through this evening,
before turning more westerly overnight.

Areas that experience showers storms today will see possible vis
restrictions early Sunday morning due to fog. Not expecting
it to be widespread, and given low predictability of areas that
will see precipitation today, have left out of the tafs for now.

Later shifts can reassess this potential as things evolve
overnight. PredominateVFR conditions forecast on Sunday, but
there will be the potential for more isolated showers storms in
the afternoon which could bring brief restrictions to the
terminals. A cold front will move through the terminals Sunday
night, ushering in a subtle wind shift to the west northwest.

High pressure takes hold on Monday, promotingVFR vis CIGS and
drier conditions.

With high pressure moving into the region Tuesday, expecting
vfr conditions to prevail. High pressure shifts off the east
coast Wednesday, bringing more moisture into the region and a
chance for thunderstorms. This could lead to sub-vfr conditions
for some terminals.

Marine
Currently, no SCA headlines in place due to light southerly
winds at less than 10 knots. That being said, scattered showers
and thunderstorms will impact the waters this afternoon and
early evening, bringing the likelihood of special marine
warnings for strong gusty winds in thunderstorms.

A cold front will move through the waters late Sunday, however
winds are expected to remain below SCA criteria into early next
week as high pressure resides overhead through Tuesday. However,
as winds turn more southwesterly on Wednesday, SCA criteria
gusts will be possible.

Hydrology
With the respite in rainfall over the last 12 hrs or so, the reports
of flooded roads has dropped. Only isolated road closures remain and
flood warnings have been discontinued.

Excess water is currently draining into the mainstem rivers, with
five forecast points remain in flood. Please monitor these warnings
for particular details.

Precipitable water values over the area have fallen off below what
was here on Friday... 1.5 to 1.75 inches with approaching 2.0 inches
over southern maryland.

Note: data for the USGS remington (renv2) river gage is now coming
in as of 1115 am. Relying on manual reports for the city dock in
fredericksburg va as data has be intermittent this morning.

Tides coastal flooding
A coastal flood advisory is in effect for the dc southwest
waterfront, arlington county and the city of alexandria through
9am on Sunday. Tidal departures are running 1 to 2 feet above
normal, which will result in tidal flooding during the times of
high tide late this afternoon and early Sunday morning. Tidal
departures have been on the decline today as winds shift to the
south and southwest, but they have been slower than expected.

Minor tidal flooding is also possible early Sunday morning at
annapolis and baltimore, but confidence in this occurrence is
not high enough at this point for an advisory due to the
declining departures. Will allow the following shift to monitor
trends and issue if warranted. Tidal anomalies will continue to
further decrease through Sunday in the wake of a cold front.

Onshore flow will return towards the middle of next week,
increasing anomalies once again.

Lwx watches warnings advisories
Dc... Coastal flood advisory until 9 am edt Sunday for dcz001.

Md... None.

Va... Coastal flood advisory until 9 am edt Sunday for vaz054.

Wv... None.
