Synopsis
High pressure will provide dry weather and a warming trend
towards seasonable temperatures into early next week.

Near term through today
High pressure centered over the southern great lakes will keep
our quiet weather pattern going. Today will not be as crystal
clear as Friday though, as cirrus and eventually mid cloud will
spill over the flattening mississippi valley ridge, aided in
development by shallow northeast u.S. Troughing and rrq jet
dynamics. The low levels remain much drier, and in fact lowered
dewpoints this afternoon on the expectation of decent mixing.

Temperatures will warm as compared to yesterday, but remain
several degrees below climatological norms.

Short term tonight through Monday
The clouds will linger through tonight, keeping radiational
cooling in check somewhat, and then get shunted south Sunday as
the surface high drifts into our area. Meanwhile, the
aforementioned upper ridge will only slowly push northeastward,
finally working into our area by Monday. As this occurs, a
plains low will drift into the deep south by Monday morning, and
then turn north towards the tennessee valley during the day.

Northward progression of moisture is a bit slower than in
previous runs, and elected to remove pops for Monday, although
clouds will be on the increase. Temperatures will complete their
quest to reach seasonal levels during this period.

Long term Monday night through Friday
Models generally agree in lifting the upper low into the ohio
valley on Tuesday and degenerating it into an open wave as it
crosses the appalachians on Wednesday. Increasing moisture and
isentropic lift will allow for rain through this period.

Pops QPF are higher in the ridges than in areas to the west
given the track of the shortwave.

The models no longer phase this first wave with a followup
northern stream disturbance, but there remains disagreement on
the handling of the next couple of shortwaves rotating through
yet another developing longwave trough. Kept some fairly general
pops in the forecast through the week. Temperatures will
generally remain near or several degrees below climatology.

Aviation 06z Saturday through Wednesday
Sfc high pressure should maintainVFR conditions through the taf
period, through mid high clouds should increase under weak upper
troughing.

Outlook...

restriction potential returns with Tue Wed low pressure.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

GOES Local Image of Mid-Atlantic    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
