Over the next few days we will experience a gradual increase in temperatures. Clouds should move into the area on Wednesday, and will hang around through the end of the week. High pressure will dominate the weather pattern leading to low chances for rain at the end of the week. By Friday night, rain chances return to the forecast.

Technical Discussion (The nerdy stuff we are discussing in class!)
Cold temperatures overnight will continue across our local area tonight due to little cloud coverage and accumulated snow leftover from Sunday's winter storm. On Wednesday upper level flow will shift to zonal across the Middle Mississippi Valley. Along with this zonal flow, low level winds will switch to a more southerly direction aiding in warmer temperatures. Expect Wednesday's max temperature to exceed well above freezing which will melt any remaining accumulated snowfall. Cloud cover for Mid-Missouri will gradually increase throughout Wednesday and cloudy conditions will persist for the remainder of the forecasting period.

For Thursday, 12UTC GFS/NAM soundings support early morning advection fog as a decently sized dry layer traps significant levels of moisture near the surface. This is further reinforced by moderate shear and a shifting wind profile present near the top of the moist layer. Upcoming forecasting periods will need to track and monitor the potential precipitation chance occurring late Friday night/Saturday morning.
