We get a mix of winter weather as we head into the holiday weekend. Today will be one of the more quiet days with a few morning flurries and a quick burst of snow, but we won't see any accumulations. The morning clouds will decrease as a strong Canadian high builds in. This will bring in dry but cold Canadian air. Temperatures today will still climb into the lower 20's but tonight you will really feel the chill. As that air filters in, temperatures tonight will drop to the single digits below zero. Along with the cold temperatures, winds will pick up behind our departing cold front and low pressure system. This happens because of a tight pressure gradient (or difference in pressure) between the departing low and incoming high pressure. Winds will gust from the north-northwest up to 35 mph.
With gusty winds and subzero temperatures, wind chills will fall as low as about -25°. This is cold enough for advisory criteria, and a Wind Chill Advisory has been issued for the entire Stateline area in effect tonight through tomorrow morning at 9am. If you have to be outside wear layers and cover your hands and head with mittens, coat, and a hat! Frost bite and hypothermia can occur in a short period of time with chills that low.
It will still be cold on Saturday, blustery conditions but we have a lot of sunshine. Northwest winds will stay gusty into the afternoon. Highs will make it to about 12 degrees Saturday afternoon. Clouds will increase going into Saturday evening, but it will still be very cold with temperatures close to 2°. You'll still need to bundle up if you're planning to head out to celebrate Valentine's Day.
A warm front gets closer to us on Valentine's Day Sunday, temperatures will warm into the lower 20's. However, with the front inching closer, we will bring in just enough lift to squeeze out some snow. There isn't much moisture to work with but we will have enough lift to allow snow to accumulate. The snow will be light and fluffy because of the dry nature, which will allow it to accumulate quickly. We could see a few inches of snow accumulate for your Sunday, so it's the perfect day to stay in and spend time with loved ones!
