2. Weak low pressure passes through the region Friday night.
A stronger area of low pressure passes south and east of the coast on Saturday.

DISCUSSION
KEY MESSAGE 1...Patchy frost expected in the Poconos this evening.

The combination of light winds, mostly clear skies and temperatures dropping into the low 30s will create the potential for frost formation. Dew points based on soundings at MPO suggest that we'll achieve 100% relative humidity at or just above freezing so I dont anticipate widespread frost but in some of the colder valley locations I anticipate there to be sufficient moisture for light icing on sensitive vegetation and or some patchy ground fog.

KEY MESSAGE 2...Weak low pressure passes through the region Friday night. A stronger area of low pressure passes south and east of the coast on Saturday.

Weak low pressure passes through the region Friday night, bringing a quick shot of light precipitation.

A deep upper trough digs through the Midwest and Gulf Coast states. Surface low pressure then develops over the Southeast United States, and then lifts north towards the Mid-Atlantic during the day Saturday. The low then tracks east Sunday night.
Wraparound rain will spread back towards the coast, but the trend is for the heaviest rain to remain offshore. The highest PoPs will be over Delaware and extreme southeast New Jersey.
Even with higher chances for rainfall, the storm total rainfall is expected to remain less than a quarter of an inch. Cloudy skies and onshore flow will keep temperatures in the 50s to low 60s.
