Zonal flow aloft and a warm front north of the Ozarks will keep warm air in place across the region today. This will help allow temperatures to be unseasonably warm again today across the whole area with mid 70s to around 80. A southwesterly low level jet will develop and move over the Ozarks tonight with southerly winds at the surface. Surface winds mainly west of Highway 65 may gust from 20 to 30mph at times overnight as well. Temperatures will be warm again with lows in the lower 60s.
Warm air advection will continue into Wednesday in advance of an approaching cold front. Temperatures during the day support afternoon temperatures in the upper 70s to lower 80s which may approach or exceed record highs. A cold front is then expected to move through the region Wednesday night into Thursday. Models have been consistent in brining rain to the region, have been inconstant with timing and amounts. These conditions have changed little, though overall rainfall with the latest models runs have shown diminishing amounts. Rain will continue through the day Thursday, though the best chances (40-55%) will remain along and south of I-44 Thursday afternoon into the evening.
Temperatures will cool and become more seasonable behind the cold front Thursday and continue into early next week. For Friday into Monday, conditions will be dry with highs around 60 and lows in the mid to upper 30s.
