DRY AIR IS EXPECTED TO QUICKLY SWEEP INTO WESTERN MISSOURI BY SATURDAY EVENING. AS UPPER SHORT WAVE MOVES INTO AREA. LOW LEVEL JET TONIGHT AND ON DAY SATURDAY SHOULD SUPPORT THUNDERSTORM DEVELOPMENT. CAPPING THIS AFTERNOON SLOWING DEVELOPMENT...BUT ALREADY SEEING THAT BREAKING DOWN IN CENTRAL OKLAHOMA...AND WITH LOW LEVEL JET...SHOULD SEE STORMS INTO FORECAST AREA TONIGHT.

TEMPERATURES WILL BE TRICKY GIVEN FRONT AND CLOUD COVER.
