THE HEAVY RAINFALL THREAT FOR THE SOUTHERN PLAINS ALONG WITH
KANSAS AND MISSOURI WILL CONTINUE AS THE UPPER LEVEL LOW REMAINS
QUASI-STATIONARY OVER SOUTHERN OKLAHOMA. BEHIND THIS SYSTEM...A
LARGE UPPER RIDGE IS FORECAST TO DEVELOP WHICH SHOULD ALLOW THIS
SYSTEM TO REMAIN STATIONARY FOR THE NEXT FEW DAYS. WITH THE
CONTINUAL SUPPLY OF LOW-LEVEL MOISTURE FROM THE GULF OF MEXICO IN
COMBINATION WITH THE STRONG FORCING FROM THE LOW CENTER...AREAS
EXTENDING FROM SOUTH CENTRAL TEXAS NORTHEASTWARD TO WESTERN
ILLINOIS ARE EXPECTED TO RECEIVE 1 TO 3 INCHES OF RAINFALL OVER
THE NEXT 24 HOURS WITH HEAVIER AMOUNTS WITHIN THE EMBEDDED
THUNDERSTORMS. RAINFALL AMOUNTS SHOULD BE ENHANCED WITHIN THE
THUNDERSTORMS GIVEN THE SLOW MOVEMENT OF MANY OF THESE CELLS.

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 1000 PM CDT. PLEASE REFER TO YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS
EVENT.
