The polar jet stream is paying North Carolina a visit, dipping farther down into the country than we normally see it. With it comes frontal systems like the rainy one that is passing through today, and truly frigid temperatures.
After the rain ends tonight, the clouds will clear quickly, allowing the temperature to plummet into the upper twenties by early morning. Any surface that still has water on it will likely freeze. Those puddles will turn to icy patches and could cause some problems on the roads tomorrow. Be aware when you travel tomorrow that ice is possible if the temperature is below freezing, and take a warm coat while youre at it. The expected high tomorrow is about 35 degrees for Raleigh and surrounding areas with winds gusting as high as 30 miles per hour. The wind chill will be brutal by our southern standards.
The highs will climb back into the normal range, which is lower 50s, by Sunday with another polar front expected to bring rain on Monday and below freezing temperatures Monday night into Tuesday. Again, even though we probably wont see snow, sleet, or freezing rain, road conditions could be slick Tuesday morning.
Taking a look farther into next week, it does look like the polar jet stream will retreat back up to the northern latitudes and give us a bit of a break from the cold temperatures.
