The raging blast of cold air is expected to hit Jefferson County on Tuesday night.

The winter weather will begin with snow on Monday night and continue through Tuesday.

According to the National Weather Service of Pittsburgh, Jefferson County is expected to get one to three inches of snow through Monday night, and a strong cold front will push through the region beginning Monday night into Tuesday morning.

Monday’s temperature will range from a high of 31 during the day to a low of 24 through the night.

Initially, there will be a mix of rain and snow that will transition to all snow on Tuesday. There could be up to an additional three inches of snow. Forecasters say there is a greater chance of increased snow north of Interstate 80.

The greatest danger will be the temperature drop on Tuesday.

On Tuesday morning, the temperature is expected to drop below freezing. By the afternoon, the temperature may fall to around 21 degrees and then continue downward.

Individuals who are traveling or plan to be outdoors are advised that wet surfaces will be quick to freeze.

A low of 0 degrees is anticipated for Tuesday night. The wind chill values could be as low as -8.

The cold temperatures and wind will make for very cold wind chill values on Wednesday and Thursday. Wind chills during the day on Wednesday will – in general – be between -5 and -20, dropping to -15 to -30 by Thursday morning.

Wednesday’s temperature ranges from a high of 2 degrees during the day and may reach -13 during the night.

Looking ahead, Thursday’s temperature is expected to have a high of near 2 degrees, moving into even colder temperatures of around -8 degrees during the night.

There is a chance of snow on Friday with a high near 17 and a low of around 3 degrees on Friday night.

The good news is the Arctic air won’t stay long, as it is expected to be partly sunny on Saturday with a high near 27 during the day and a low of around 18 degrees on Saturday night.

Be ready for a chance of rain turning into freezing rain and sleet on Sunday.
