ROCKFORD (WREX) – The warmth from earlier this week has came to a crashing end.
With a cold Canadian high pressure located over the Stateline, temperatures this afternoon will only climb into the 40’s. Clouds moved in overnight, which kept temperatures from falling to freezing across most of the region, and will linger through the day today. The sun will not be much help today in allowing those temperatures to rise very far. In fact, there is a chance for some light rain especially south of Rockford. Since the precipitation is moving in earlier in the day, there is an outside chance of a few flakes of snow mixing in, but certainly no accumulation is expected. Before any precipitation can fall, the atmosphere above the region has to moisten up. The low-levels of the atmosphere are very dry, so precipitation may fall through that layer, but it does evaporate as it falls through that dry layer. This is called “virga” in the meteorology world.
Aside from the very small chance of precipitation today, it will remain chilly and cloudy. With high temperatures forecast to be in the mid-40’s, now is an excellent time to remind everyone that average highs are in the mid-60’s this time of year. On Monday, the high temperature in Rockford rose to 84-degrees, nearly twenty-degrees warmer than average. The weather has certainly shifted in the span of four days. If Friday Night Football is in your plans for this evening, bring a coat or at the very least a blanket. If the concession stand sells hot cocoa, spring for it. All the help you can get to hopefully stay warm. Temperatures will fall into the upper-30’s by the time the games wrap up, with a light breeze making it feel like it’s closer to the freezing mark of 32.
