It's been a wet Wednesday, as our campus has seen an excessive amount of rain throughout the day. As the low moves through our region and off to the east, we will be seeing a period of calmer weather over the next few days. With this calmer weather, we will be seeing cooler weather the next couple of days. We used the GFS model to formulate this forecast because the GFS had most accurately forecast the observed current conditions at the time of forecasting.
The surface low that brought our rain today was caused by a short wave trough that is visible at 300mb. As the short wave trough moves off to our east, it will be followed by a long period of zonal wind flow aloft, which is evident at 300mb, 500mb, and 700mb heights.
Wednesday night and Thursday look to be calm. The surface low that passes Wednesday night will also bring a cold front through, ushering in colder temperatures for Thursday. After the passage of that cold front, the conditions will clear up, and we will be seeing a clear sky. The clear conditions will continue until mid level moisture moves in later Thursday night.
Friday will have colder temperatures and cloudiness. 700mb analysis shows ample moisture move over the CWA late Thursday night. This moisture will remain over the area through all of Friday, and will exit the region early Saturday morning. 850mb analysis shows a brief pocket of moisture that slides over mid Missouri Friday night, and dissipates not soon after. The moisture will lead to overcast conditions for all of Friday. Overcast conditions are supported by model soundings showing mid level saturation throughout the day Friday. The colder temperatures will be due to a surface level high pressure system located over North Dakota and Minnesota. This system will feed Missouri with cold arctic air out of the Canadian north. The cloud cover will dissipate later Friday night, as the moisture exits the region.
