Sunny, Pleasant

A few clouds moved through the area this morning and kept temperatures in the low to mid 40s. We remain under the influence of northwest flow aloft due to the cut-off low to our east. The models overestimated the strength of the cold air advection yesterday, which lead to highs topping out a little warmer than I expected. Once again, I think models may be a tad too cool today as a warm air advection regime will commence. Nonetheless, a cooler surface air mass did filter into the area overnight, and this should keep highs slightly cooler than yesterday. With sunny skies highs should top out near 67 this afternoon. A good radiational cooling setup will support some chilly temperatures tonight. However, I don't like going to aggressive with temperatures when warm air advection is occurring. Still, lows should be able to drop to near 39 tomorrow morning.
