SLIGHT CHANCES FOR SHOWERS AND ISOLATED THUNDERSTORMS WILL PERSIST
INTO TUESDAY MORNING AS THE WEAK UPPER LEVEL WAVE PASSES OVER THE

AND RAISING TEMPERATURES ACROSS THE REGION. A SERIES OF UPPER
LEVEL DISTURBANCES AND FRONTAL PASSAGE WILL CREATE BETTER CHANCES
FOR SHOWERS AND POSSIBLE STRONG TO SEVERE STORMS TO DEVELOP ON
WEDNESDAY...AND PERSIST THROUGH THE END OF THE WEEK. MODELS DEPICT
A STRONG LOW PRESSURE SYSTEM ADVECTING OUT OF THE SOUTHWEST INTO THE
CENTRAL PLAINS LATE FRIDAY INTO SATURDAY. ALL MODES OF SEVERE
WEATHER WILL BE POSSIBLE DURING THIS ACTIVE PERIOD. OVERALL SEVERE
RISKS AND PROBABILITIES WILL CONTINUE TO BE REFINED WITH LATER
