Synopsis:
The exiting of the low pressure system up the Atlantic coast takes with it the precipitation we have been seeing. Cold temperatures return along with high pressure until Thursday evening, when the next system moves quickly across the state. Effects from this system will linger in the form of bitterly cold temperatures throughout the state and a tendency toward snow showers in the high elevations and southeast of Lake Erie.
Short-term:
Mixed precipitation and rain are the norm for much of the state this afternoon and evening, with a tendency toward mixed precipitation as the evening progresses. Precipitation in the eastern half of the state could be minimal, as current radar imagery shows that it is beginning to dissipate over eastern portions of Ohio. After the passage of this cold front, high pressure builds in to bring a few days of clear skies and colder temperatures. We expect some orographic snow showers in the Laurel Highlands and lake effect snow showers in the Northwest regions of the state.
Long-term:
The next system to affect us moves in Thursday night. GFS and WRF are in agreement that this system will quickly pass through Pennsylvania to develop into a Type B coastal storm. Amounts of precipitation from this system are uncertain, but the ensemble forecast keeps most of the heavy precipitation around the Pennsylvania/New Jersey border. Once this low develops GFS expects it to quickly move up the coast. Later shifts will have to keep an! eye on this system for exact timing and movement away from the current predicted path, as this could affect precipitation totals for the eastern portion of the Commonwealth. Behind this system we expect temperatures to drop across the entire state to some of the lowest values we have seen this season.
