A weak wave of low pressure passed well south of the area last night. Some light wintry precipitation fell across southwestern Pennsylvania, but it remained dry across our area.
High pressure will briefly build across the area today, with skies becoming partly cloudy this afternoon. High temperatures today will rise to the mid 30s.
An Alberta clipper will dive southeastward into the Great Lakes tonight and across northwestern Pennsylvania on Thursday. Skies will become mostly cloudy tonight as the system approaches. Scattered snow showers are possible after midnight. Snow showers will continue through the day on Thursday as the clipper drags a cold front eastward across the area. Lows tonight will fall to the low 20s with highs on Thursday in the mid to upper 20s with brisk northwesterly winds.
Lake effect snow showers will persist Thursday night, then gradually taper off Friday. Lows Thursday night will fall to the teens. Friday will be another chilly day with highs in the mid to upper 20s.
Snow fall accumulations tonight through Friday should be relatively minor.
High pressure will move across the area Friday night, and this will set up a milder southwesterly flow on Saturday. Under partly cloudy skies, lows Friday night will dip to the mid 20s with highs on Saturday rebounding to the mid to upper 30s.
An arctic cold front will sweep across the area Saturday night ushering in much colder temperatures. The lake effect snow machine will ramp up as well with snow showers possible from Saturday night, right through the beginning of next week.
