Synopsis
Cold and dry high pressure moving into the forecast area from
the west will remain in place through Saturday. The high will
be off the southeast coast Sunday. Moisture will increase ahead
of a cold front Monday. A warming trend will occur over the
weekend and early next week.

Near term until 7 am Friday morning
Overnight forecast remains on track.

Dry surface high pressure building over the region with with h5
confluent heights should maintain clear skies. Expect
temperatures to remain well below normal. Temperatures are on
track for low in the low to mid 20s most locations. Given snow
cover over northern lancaster county, kept lows in the teens.

Short term 7 am Friday morning through Sunday night
Dry conditions will prevail through Sunday night. There will be
a weak mid-level shortwave moving through the region Saturday
night, but there will be very little moisture, and only expect
increased cloudiness. Surface high pressure will continue to
dominate, though it will shift slowly offshore. This will cause
increasing southwesterly flow and a warming trend. By Sunday,
highs will be in the 60s. However, overnight lows will remain
cool throughout the period due to mostly clear skies and
radiational cooling.

Long term Monday through Thursday
More significant upper troughing will begin to affect the
region Monday and moisture will increase. The models display
the associated cold front approaching Monday and moving through
the area Monday night or early Tuesday morning. Rain will be
likely Monday night. A dry air mass will then dominate behind
the front during much of Tuesday and Wednesday. Temperatures
will remain above normal during this period.

Aviation 03z Friday through Tuesday
Vfr conditions through the period.

High pressure will continue to build into the area from the west
for Friday promoting clear skies. Winds will be light and
variable or calm at times overnight. The dry airmass will
preclude any fog formation Friday morning. Surface winds will be
light and generally out of the wsw on Friday with the center of
the surface high still to our west.

Extended aviation outlook... No
significant impacts to aviation expected through Monday.

Cae watches warnings advisories
Ga... None.

Sc... 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.
