Mostly Cloudy, Slightly Cooler

Skies remained clear for most of the night, but a stratus deck has moved into the area from the north. It appears that these low clouds will hang out for most of the day in some capacity. We could see some peeks of sun this afternoon, but the clouds will certainly dominate. The front that moved through yesterday will provide a temporary cool down from the last couple of days. Highs should top out around 60 this afternoon. Our weather pattern will quickly change again tonight as our next storm system takes shape over the western High Plains. Leeside cyclogenesis will allow southeasterly winds to return overnight, and a few cirrus clouds in advance of the storm system will approach the area before midnight. This should prevent ideal radiational cooling, but temperatures tomorrow morning will be near 45.

Our recent thaw will come to an end by the time the weekend is over. The big storm system out West will allow for two more warm days with highs in the 60s Saturday and Sunday. A chance of rain and possibly some thunderstorms will arrive late Saturday night and early Sunday morning. I was initially concerned about the chance for severe weather, but the occlusion of and the timing of this system should prevent those concerns. Strong dynamics but weak thermodynamics should allow for a forced line of storms to develop. These storms may produce some strong winds early Sunday morning. A cold front should pass through Sunday afternoon, and a much cooler and drier air mass will engulf the state. Cooler than normal temperatures will dominate early in the week followed by near normal temperatures late next week. The pattern for the next couple of weeks doesn't suggest any prolonged periods of anomalously warm weather.
