Slowly weakening low pressure centered just east of Ocean 
City Maryland early today will continue to spiral some bands
of very light rain or drizzle into the Susquehanna Valley and 
points east this morning. This storm system will move toward
the Southeast New England coast this afternoon and tonight,
gradually bringing drier air into the region this afternoon 
into Thursday.

Temperatures to start today will be fairly uniform statewide, 
and mainly in the low to mid 50s.

Clearing skies are expected for later today and tonight as a 
weak ridge of high pressure slides east across Pennsylvania. 

A significant warm up is expected to start today. High 
temperatures this afternoon will range from the mid and upper 
60s over the Delaware Valley, to the mid and upper 70s across
the lowlands of western PA. 

A disturbance aloft and warm frontal boundary at the surface 
will lift northeast across the commonwealth Thursday, bringing 
a good chance for showers and scattered thunderstorms across
the western half of the state Thursday afternoon and evening. 
A few of the thunderstorms could contain gusty winds and hail.

through Saturday.

Historical Weather And Climate Facts For Today

Killer frosts were reported in the Deep South. The frost was quite severe
around Huntsville AL, and highlighted a backward spring in the South that
year. (David Ludlum)
An unusually strong occluded front swept out of the Gulf of Alaska and
produced the first April thunderstorm of record at Fairbanks. Pea size hail
fell northeast of Fairbanks from thunderstorms whose tops were less than
8000 feet. (The Weather Channel)
Severe thunderstorms associated with an intense cyclone spawned a total of
forty-seven tornadoes in two days from Louisiana to Upper Michigan. The
tornadoes killed 16 persons and injured 259 others. (Storm Data)
