Heavy lake effect snow possible across northwestern Pennsylvania today (Video)

Winter Weather headlines are now in effect for much of northwestern Pennsylvania as lake effect snow continues.

Cold air will continue to spill southward across the lake today. A weak cold front will move across western Pennsylvania this morning. This front has caused the snow shower activity to become somewhat disorganized. Later this morning, winds will turn to the west-northwest and snow showers will begin to reorganize and intensify.

Snow showers and squalls are likely this afternoon with heavy accumulations possible, especially across Erie and Crawford counties. The snowfall amounts will vary greatly from place to place.

Temperatures will only rise a few degrees today, reaching the low 20s around mid day. Temperatures will hold steady of fall slightly this afternoon.

The steady west-northwesterly flow will continue tonight with snow showers and squalls likely. Again, heavy accumulations are possible in areas where squalls persist. Lows tonight will fall to the single digits. Wind chills will dip to -10 to -20 overnight. A Wind Chill Advisory has been issued for tonight and Tuesday morning for all of northwestern Pennsylvania

Tuesday will be quite cold with lake effect snow showers and squalls persisting with additional accumulation likely. High temperatures on Tuesday will only rise to the low teens.

Lake effect snow will continue to be in the forecast Tuesday night and Wednesday as a favorable flow across the lake remains in place. Lows Tuesday night will be in the single digits with highs rising to the mid teens on Wednesday.
