.DISCUSSION...
KEY MESSAGE 1...Temperatures will moderate through this weekend
with a couple weak systems bringing chances of light
precipitation, mainly rain, before a cool-down early next week.

Low pressure moving through eastern Canada will push a warm
front through the area today. This will lead to temperatures
returning to more seasonable values with highs generally in the
upper 40s to low 50s. A stronger low will then lift by to our
north on Friday as it moves from the lower Great Lakes towards New
England. The increasing southerly flow associated with this
system will help continue the warming trend with highs generally
getting into the upper 50s to low 60s for most areas. The system
will also drag a weakening cold front through the area Friday
night with some associated rain/showers. Some showers could arrive
in our N/W zones from Berks County northward through the Lehigh
Valley into the southern Poconos as early as late Friday but most
of the precip should occur during the evening and overnight period
Friday night. All rain is expected as lows Friday night will be
generally in the 40s (upper 30s over the southern Poconos).
Precipitation amounts should be generally in the tenth to quarter
inch range or less.

The warm advection pattern will continue into Saturday as yet
another system develops to our west. Expect a partly to mostly
sunny day with highs generally in the low to mid 60s with the
exception of the higher elevation areas in our N/W zones where
highs should be mainly in the 50s. As the SW flow associated
with this approaching system increases into Sunday, it will be
even warmer with highs generally in the 65 to 70 range. The
exception will again be for higher elevations in the southern
Poconos and NW NJ as well as right near the coast where highs
will generally top out in the upper 50s to low 60s.

The cold front with the aformentioned system will move through
late Sunday into Sunday night with another round of some
rain/showers. Colder Canadian high pressure will then move in in
its wake with a return to more seasonable but fair weather for
the early to middle part of next week.
