Mostly Cloudy, Cool

A powerful upper air system that moved through over the weekend has exited to our east this morning. In its wake, wrap around clouds, light rain and snow, and cold air advection will keep temperatures on the chilly side today. Some light rain will be possible through 11 a.m., but I think we'll likely remain dry. Forecasting the dissipation of the cloud cover will be the key to today's temperatures. As the upper air system moves into eastern Texas we should see clouds slowly break up around lunchtime, but I am worried that a weak upslope component to the wind could allow clouds to hang tough through the afternoon. I'll be optimistic and forecast some breaks in the clouds after noon, but it will still remain mostly cloudy. Highs should top out around 44 this afternoon, which will be 14 degrees below normal. Winds will be breezy this morning, but should subside throughout the day as high pressure begins to build into the region. Fog will likely be a concern tonight, particularly after 10 p.m. Lows tomorrow morning will dip down to 29. We should get into a warmer pattern by mid week as a trough moves into California and amplifies a ridge across the High Plains. Highs should be back into the 60s by Wednesday. Thursday may be an exception as cool upslope flow develops, but highs should rebound nicely in time for the weekend.
