Synopsis
Rain and freezing rain expected today before changing to all
rain by tonight for most locations. Dry weather should return
Thursday and Friday under building high pressure.

Near term until 6 am Thursday morning
Patchy drizzle and freezing drizzle (where temps remain at or
below freezing) will continue until precipitation picks up
again late this afternoon and into the evening with increased
lift ahead of a front progged to cross the region overnight.

Surface temperatures will continue to rise and by the time
precipitation picks up again the risk of freezing rain should
be largely along and north of i-80 and in the
ridges... Diminishing through the evening as surface temperatures
continue to rise. The ridges and jefferson county will be the
last to changeover... With garrett county the final holdout until
around midnight when winds veer to the southwest... Allowing for
a relatively rapid increase in temperatures. Thus have allowed
the advisory to expire for southern non-ridge zones... While the
remaining warnings and advisories continue with the threat of
freezing rain.

With the saturated ground, and streams already running high,
will maintain the flood watch.

Short term 6 am Thursday morning through Friday night
Additional precipitation will be most intense during the early
part of the evening before shortwave support and deep layer
moisture exit. Any lingering freezing rain ne- SE of pit should
end this evening as winds veer to the s, ending the cooling
upslope flow. The sfc low is progged to track to ontario
tonight, dragging a cold front across the region. Not much rain
is expected with FROPA itself with upper support already
departed. Dry weather is then expected Thursday and Friday under
building high pressure.

Long term Saturday through Wednesday
Rain chances should continue through the weekend as the central
conus trough approaches and crosses the region. Dry weather
should return Monday under a ridge before a fast moving trough
in zonal flow aloft crosses the region Tuesday. Above average
weekend temperatures should return to seasonal levels by Monday.

Aviation 20z Wednesday through Monday
Ifr MVFR conditions prevail for most terminals as snow showers
have either left the area or transitioned to rain. Fkl duj may
see a combination of fzra or sn for just a few more hours before
turning to all rain. Otherwise, a general break in precipitation
is expected for a few more hours before rain overspreads the
region again late this afternoon. Ceilings will remain low the
entire time with heights on either side of 1000 feet.

Precipitation will once again exit the region around or shortly
after midnight for all terminals, though low ceilings and
perhaps some drizzle will linger for a few hours later. Much
improvement will be noted after dawn tomorrow as ceilings lift
and break up.

Outlook
Restrictions and gusty wind are expected until Thursday with
the passage of a cold front. Restriction potential returns with
weekend low pressure.

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.
