It will be windy today as well with gusts in excess of 40 mph possible.
A surge of even colder air will spill southward across Lake Erie and northwestern Pennsylvania tonight. As the colder air arrives, instability over the lake will increase. Snow showers across the area will intensify with heavy squalls possible, especially after midnight. Lows tonight will be in the low teens.
It will be breezy and cold on Monday with occasional snow showers and squalls likely. There will also be areas of blowing and drifting snow. Highs will only rise to the mid to upper teens.
It will remain breezy with snow showers and squalls continuing through Monday night and Tuesday as the cold west-northwesterly flow across the lake continues. Temperatures will fall to the single digits Monday night, then only rise to the low teens on Tuesday.
Snow fall accumulations in excess of a foot are likely across the area through Tuesday. Some locally higher amounts in excess of 2 feet are possible where squalls persist.
The cold, snowy weather will last into the middle of the week with additional accumulations likely.
