Columbia is the home of the University of Missouri, and like most of the population of Missouri, isn’t terribly far from St. Louis.

At 154PM, CT, Columbia was reporting a temperature of 83 degrees with fair skies. Low pressure moving through the northern Plains was inducing brisk southerly winds that were bringing temperatures up to unusually high levels, and introducing a little bit of moisture to the atmosphere. Columbia was on the cusp of drought, but is not presently under a red flag warning, even with the gusty winds.
The strong feature in the Plains is going to gain a tighter circulation and start moving north toward the Dakotas and Minnesota. The cold front, owing to the primarily northerly vector of the system, will be slow moving. The boundary will flare in Kansas and Oklahoma tomorrow morning, and slowly traipse across Missouri before arriving in Columbia in the evening on Monday. The base of the trough will be fertile ground for more cyclonic development, and a wave will develop in the Red River Valley and move north, ensuring that after the rain and thunder start on Monday, it will persist, though likely with less thunder, through the early part of Tuesday, with colder temperatures following.

It is non-standard temperature season! What a rainy forecast for eastern Missouri. I wouldn’t be surprised to see several inches of rain in some parts of the state. The low is easily apparent up in Montana even this afternoon.
