232 pm est Thu nov 14 2019

Synopsis
A low pressure center is expected to develop off of the
southeast u.S. Coast Friday and meander off the carolinas
through Sunday. Meanwhile, a cold front is expected to push
through the area Saturday. The low will slowly lift
northeastward offshore through early next week as high pressure
gradually retreats into the canadian maritimes.

Near term through tonight
Bkn-ovc dense cirrus layer tonight as jet streak passes
overhead. There will also be an increase in low clouds across
southern zones due to ssw flow. Light rain is possible across
southern st. Mary's county tonight into early fri. Not as cold
as the past two nights with lows in the mid to upper 20s except
mid 30s downtown areas.

Short term Friday through Saturday night
Warmer on Fri with temps rising AOA 50f. Continued high level
overcast as area remains in the vicinity of jet streak. Low-mid
cloud shield associated with coastal low pressure will also be
located in the vicinity of akq lwx CWA border. Tightening
pressure gradient between coastal low pressure and high pressure
to the north will result in strengthening winds Fri night and
especially Saturday. At this time, no precipitation is expected.

Long term Sunday through Thursday
The long term presents some uncertainty, especially going into early
next week. Low pressure developing off the carolina coast will track
northeastward as strong high pressure centered over new england
departs into the canadian maritimes. The majority of the model
guidance keeps this low offshore and should keep most of the region
dry. However, if the low tracks slightly closer to the coast, a few
spotty showers can occur early Sunday morning for areas mainly
inside the i-95 corridor. In any case, breezy conditions are likely
to occur, potentially extending into Monday.

The middle of next week presents even greater uncertainty as an
upper level trough is expected to dive southeastward across the
region. The risk becomes another coastal low developing off the
carolina coast which could bring wind rain to the region overnight
Tuesday into Wednesday. However, the timing of the trough moving
through the region and its interaction with the parent
shortwave is still to be determined. For now, the latest model
guidance has trended slower weaker with any coastal low
development which would keep the region mostly dry. Temperatures
look to slowly moderate through the long term. However,
depending on the exact placement of the low, temperatures may
remain below normal for a longer period of time thanks to clouds
and rain.

Aviation 19z Thursday through Tuesday
Vfr conditions expected through Saturday. Winds expected to
strengthen Fri night into Saturday with gusts up to 25 kt
expected especially on Saturday.

Conditions most likely remainVFR Sunday and Monday as a low
pressure system passes to the southeast and east, though a gusty
northeast to north wind is likely. There is a small risk that some
rain may overspread the region if this low tracks further west,
which could result in sub-vfr conditions.

Marine
Winds are expected to strengthen Fri night into Saturday with
gusts up to 30 kt possible especially on Saturday as pressure
gradient tightens between strong high pressure to the north and
low pressure off of the southeast coast.

Small craft advisory conditions are expected Sunday into Monday
morning, before tapering off later in the day on Monday. This is due
to a strong area of low pressure that will be tracking well
offshore.

Climate
No record lows were set at any of the three main airports this
morning.

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 L-36.com 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.
