Winter weather will continue for much of the weekend with only small reprieves here and there. This afternoon's snow will end later this evening leaving behind it cloudy skies. The clouds will linger throughout much of the forecast period. Another round of winter weather will move in late Saturday night and persist through Sunday. Temperatures will remain fairly steady throughout the weekend remaining right at or just below freezing.

Technical Discussion (The nerdy stuff we are discussing in class!)
We are in store for a very active weather pattern over the forecast period. Snow will linger throughout this evening due to an increase in atmospheric moisture. We see that moisture begin to dry out briefly in the mid and upper level, but the moisture will return Saturday afternoon. The mid-levels from Saturday through the rest of the weekend will remain relatively saturated, providing the moisture needed for our next wintry event. Saturday winds shift to out of the southwest and will provide some warm air advection helping to warm our temperatures slightly.
 Overnight Saturday and into Sunday is when we can expect the next round of winter weather. A low pressure system makes its way into Missouri early Sunday morning. Winds will shift from southwesterly to northwesterly, this will aid in some slight cold air advection, however this will not have a major impact on our temperatures. Models are in disagreement as to the type of precipitation we can expect and how long it will last. GFS has mid-Missouri right on the line between a wintry mix and snow. North of I70 receiving the snow while south could see some wintry mix. GFS also has the lifespan of the event ending Sunday afternoon. While the NAM is showing snow for central Missouri, and has the precipitation lasting into Monday morning, with wrap around precipitation from the low that moves through. The models due agree that we will likely receive another 2 inches of snow. At this time Monday looks to dry out with temperatures remaining similar to the rest of this weekend.
