A strong high pressure system will govern our weather for much of the period. In its wake, we will see tranquil, albeit much cooler than normal weather during this period. As a storm system passes to our south tonight into tomorrow, we will a thick layer of high clouds, but now precipitation is forecast. Another system will move west of our area Sunday night into Monday, producing more high-level cloudiness. Overall, daytime highs will vary only slightly from day to day.

Technical Discussion (The nerdy stuff we are discussing in class!) 
A seemingly quiet weekend ensues over mid-Missouri for much of the forecast period. A big anticyclone is parked over much of the Midwest. Mid-Missouri will remain in the center of the air mass until early next week. Sky conditions and temperatures will remain relatively constant for the forecast period. GFS 700 hPa RH predicts drying out Friday night and remaining very dry for the rest of the weekend. This does not mean clear skies, however, as GFS Skew-T's show persisent saturation with respect to ice in between 500-300 hPa. Over the course of the forecast period, high clouds will thin out during the day letting some sunshine in. Skew-T's for Sunday indicate enough clouds clearning to let our temperatures rise just a few degrees. GFS 500 hPa vorticity shows a clipper coming down from Alberta late Sunday into early Monday. This system will knock temperatures back to the persistent highs seen thus far.
