Synopsis
High pressure will bring dry weather for Thursday before rain
chances return Friday.

Near term until 6 am Thursday morning
Changes for the late eve update included further downward
adjustments to precip. Probability as showers have rapidly faded
with the advance of the cold front. Low clouds over e.C. Ohio
zones have also been suppressed, and that trend will continue
into Thursday although stratocu may linger over areas north of
pittsburgh for awhile.

No changes were made to the overnight low forecast - 3 degrees
under the averages in the changing airmass.

Short term 6 am Thursday morning through Saturday night
Short wave ridging and a brief spell of high pressure at the
surface will keep the area dry Thursday. A slow moving southern
stream system is projected across the mid-atlantic region Thursday
night. Models differ slightly on the exact track as it turns
the corner and begins to phase with the broader trough. This
track will play a vital role in just how far west the
precipitation shield will come. Will carry a blend, but will
favor the easternmost models (nam, ec). Regardless, rain chances
will increase later in the day Friday and Friday night as the
broader trough axis crosses the area. This will also usher in
cooler than average temperatures for the early part of the
weekend.

Long term Sunday through Wednesday
High confidence through the extended period as the rainy and
cool end of the week gives way to a warm and dry trend. High
pressure will begin to build at the surface late Saturday night
into Sunday. This will bring an end to precipitation chances and
establish clearing sky. Temperatures will temporarily be held
in check Sunday with lingering northwest flow aloft, but this
will quickly change heading into the middle of next week. A
building ridge will pass to our east by Tuesday evening
enhancing warming with southwest flow. Highs will soar into at
least the mid and upper 70s by Wednesday. The next appreciable
chance of precipitation will come by late next week.

Aviation 01z Thursday through Monday
Restrictions via low-MVFR and ifr stratus are expected to further
ease as high pressure builds and dry advection continues tonight.

GeneralVFR can be expected for Thursday with light wind.

Outlook...

the next chance for general restrictions is expected with the
crossing of weak low pressure on Friday.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... 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.
