Synopsis
High pressure builds over the gulf coast region through Monday
night, as low pressure moves through the northern tier of the
nation. A more prominent low pressure system will move from the
great lakes into new england Tuesday through Tuesday night,
pushing a strong cold front through the local area. Expect markedly
colder temperatures for Tuesday night and Wednesday.

Near term through Monday
The current surface analysis indicates a large area of sfc high
pressure (~1030 mb)centered from south texas to the gulf coast
states. Low pressure genly prevails north of the eastern great
lakes. A westerly flow in place over the local area with mostly
sunny skies. Temperatures in snow covered areas are genly
holding in the upper 30s to around 40 f, while snow-free
sections of SE va and NE nc are into the lower-mid 40s.

Next shortwave aloft looks to dive ese from the midwest later
tonight and bring more mainly mid level clouds to the northern
1 2 of the CWA overnight. These clouds and some low level mixing
(albeit weak) will tend to keep tonight's lows from being as
cold as they otherwise would be if sfc high pressure were
centered over the area. Partly-mostly cloudy north and partly
cloudy to mostly clear south. Still did undercut MOS by a few
degrees in snow covered areas, with lows mainly ranging from
the mid 20s to lower 30s. Skies again turn mainly sunny behind
the departing shortwave for Mon and it will become a little
milder with highs into the mid- upper 40s most areas (lower 50s
se).

Short term Monday night through Wednesday
Partly to mostly cloudy Mon night and with a southerly flow,
should be a little warmer with lows 30-35 f. Enough SW flow on
tue for highs into the mid-upper 50s SE to the upper 40s nw.

Turning blustery and dry late in the day from NW to se.

Front pushes SE of the local area Tuesday evening into
Wednesday morning. Temperatures tumble into the 20s 30s Tuesday
night, with early morning lows in the teens NW to 20s elsewhere
Wednesday morning. Brisk NW winds will quickly knock wind chills
down into the 10-20 f range Wed morning. Even with mainly sunny
skies wed, highs will struggle to get above the lower 30s N and
mid 30s s... With wind chills remaining in the 20s or colder.

Long term Wednesday night through Sunday
A progressive wnw flow pattern is expected late this
week through next weekend featuring a series of NRN stream moisture-
starved clipper systems. The first wave pushes through during the
Wednesday night Thursday timeframe. The 10 12z ECMWF is about 12hrs
quicker than the gfs, but regardless pops are less than 15% with
limited moisture and downslope flow. Another wave quickly follows
Friday. The GFS is more NRN stream dominated while the ECMWF pushes
a SRN stream wave off the southeast coast. Again, there is little
support for pcpn locally, so forecast pops are less than 15%.

Shortwave ridging prevails Saturday with another quick moving trough
pushing through the region Sunday. High temperatures Thursday-
Saturday will generally be in the 40s to around 50f se, then low mid
50s by Sunday as the aforementioned trough will provide mixing with
limited caa. Low temperatures will primarily be in the 20s for much
of the area to low 30s SE later this week, and then rise to the
upper 20s mid 30s (upper 30s around 40f far se) by the weekend.

Aviation 21z Sunday through Friday
A mainly quiet period with mostly clear conditions this evening
followed by mid high clouds and CIGS of 10-20k ft (mainly north)
from 03-09z. Light SW winds tonight, shift to the west at around
10 kt on mon.

ExpectVFR conditions to prevail for the most part through the
week, though winds are expected to become strong and gusty later
tue and Tue night into Wed with the passage of a strong cold
front.

Marine
Ended the SCA hazards over the ocean with this forecast package as
seas have dropped below 5 ft. Sfc high pressure builds over the se
states tonight, and with a slight increase in the pressure gradient,
have hoisted a marginal SCA for the bay for a short period of 15-20
kt winds. Sub-sca conditions then into the day Mon as a clipper
system approaches the oh valley. This system will drag a strong cold
front through the waters on tue, with SCA conditions expected over
much of the marine area lasting from Tue through wed. Low-end gales
are psbl by Tue night, esply over the coastal wtrs.

Akq watches warnings advisories
Md... None.

Nc... None.

Va... None.

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.
