Synopsis
Dry conditions will continue before rain chances return with
weekend low pressure. Strong winds expected on Sunday.

Near term through tonight
High pressure will maintain dry conditions while winds lessen
this evening as the gradient weakens and winds decouple.

Short term Friday through Saturday night
Dry weather will continue as the aforementioned sfc high
continues east across the region. A disturbance passing south of
the forecast area early Friday should result in increased cloud
coverage across southern zones... But precipitation chances are
too low for mention in the forecast.

An upper low currently over the desert southwest will deepen as
it tracks ene across the central CONUS and near the great lakes
by Saturday night. Increasing moisture and shortwave support in
sw flow aloft ahead of this feature will begin to increase
rain chances early Saturday... Expanding north over the course
of the day. Garrett county md could see a brief period of
freezing rain Saturday morning until sfc temperatures rise.

Rain should overspread the area Saturday and Saturday night with
the increasing moisture and shortwave support and as sfc low
pressure develops and quickly tracks from the plains to the
great lakes upper midwest region, pulling a warm front N across
our area. Model progs indicate the best potential for heavy rain
should stay just S of the area. Above seasonal average
temperatures are expected with strong warm air advection in
place.

Long term Sunday through Thursday
Models remain in fairly good agreement with overall pattern on
Sunday... Which looks to be an ideal setup for a significant wind
even across the forecast area. Location orientation of upper
level features and surface low, u and v component anomalies, top
analogs, and 99th percentile ensemble wind forecasts (relative
to model climatology) all support a strong wind event as well.

(for all locations... Not just the higher elevations - based off
a local studies) maintained mention of this in the hwo being
still 3 days out... But if models remain consistent... Warning
level winds would definitely be possible.

Weak ridging in zonal flow aloft should return dry weather for
Monday and Tuesday before the pattern amplifies and another
trough tracks SE across the region by midweek, returning precip
chances to the forecast.

Aviation 19z Thursday through Tuesday
PredominantVFR conditions expected under building high
pressure, with westerly winds gusting to 20 knots through the
afternoon, becoming light by sunset as daytime mixing ceases.

High pressure should maintainVFR conditions tonight into
Friday.

Outlook
Restrictions are likely in rain late Saturday as low digs
toward the great lakes and invokes strong southerly flow across
the upper oh region. Dangerously windy conditions are expected
for Sunday.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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.
