As an arctic front approaches, some snow showers, even a heavier squall, will move into the area by Tuesday morning. Accumulation will be an inch or less in the valley spots with 1-3” likely across the Laurel Highlands and near and north of I-80. What’s more of a problem than the accumulation of the snow is a quick drop in temperatures that will come with and just behind the snow. This can make roads slippery and the kind of situation that can spark many accidents, even pile ups on some major roadways. You may want to leave earlier than usual Tuesday morning.
The rest of Tuesday will be windy and it will turn even colder with only scattered flurries and a snow shower. Do watch for some blowing snow. Temperatures will drop through the 20s and into the teens in places. Wind chills will drop below zero. A second arctic front will move through early Wednesday with another round of snow showers and a heavier squall. Behind the front, temperatures will likely drop into the single digits with a bitter wind. Once we get below 10° early Wednesday we will likely not rise out of the single digits until sometime Friday afternoon. We’ll have some sunshine Wednesday afternoon and Thursday, but that sun will only be out for moral support. It will turn dangerously cold at night with wind chills well below zero. Temperatures Wednesday night and Thursday night will drop well below zero.
A disturbance may bring a period of light snow Friday, especially the farther south you are in the region. It will still be cold Friday night and we will likely be in the single digits when Phil comes out of his burrow Saturday morning. Saturday afternoon will not be quite as cold with some sunshine and highs in the 20s. We’ll turn even milder on Sunday despite an increase in cloudiness. Some drizzle and a bit of rain is likely later Sunday into Sunday night and some of that may freeze on untreated surfaces. We’ll have an even milder day on Monday despite some rain showers. Temperatures will stay above average for the middle of next week.
