MOVE OVER THE REGION LATER TONIGHT. SHOWERS AND THUNDERSTORMS WILL
DEVELOP OVER THE PLAINS BY EARLY TO MID EVENING AND INCREASE IN
INTENSITY AND COVERAGE INTO THE EARLY MORNING HOURS OF THURSDAY. THE
MAIN CONCERN WITH THIS ACTIVITY WILL BE LOCALLY HEAVY RAIN,
ESPECIALLY OVER THE FAR EASTERN PLAINS WHERE DEEPER MOISTURE IS
NOTED IN THE DATA. SOME LOCAL FLASH FLOODING CAN NOT BE RULED OUT
AND WE ARE UNDER A SLIGHT RISK FOR FLASH FLOODING OVER THE PLAINS

THE PLAINS TOMORROW MORNING, AND SOME SHOWERS MAY STILL BE ONGOING
OVER THE FAR EASTERN PLAINS EARLY TOMORROW MORNING. SKIES WILL CLEAR

ONLY IN THE LOWER TO MID 80S PLAINS AND MID 80S VALLEYS. SOME
ISOLATED LATE AFTERNOON THUNDER MAY OCCUR ALONG THE MTN/PLAINS

80S ACROSS THE VALLEYS AND PLAINS.
SUNDAY...TEMPERATURES ARE FORECAST TO SHOOT UP AGAIN, WITH VALUES IN
THE MID TO UPPER 90S ACROSS THE PLAINS AND MID 80S VALLEYS. SHOWERS
WILL BE ISOLATED ACROSS THE PLAINS.
ANOTHER COLD FRONT MOVES ACROSS THE REGION LATE SUNDAY INTO EARLY
MONDAY AND AND MAX TEMPS AT THE BEGINNING OF THE WEEK FALL BACK DOWN
IN THE 80S MONDAY, WITH EVEN COOLER WEATHER MOVING INTO FOR TUESDAY.
WE SHOULD SEE A BETTER CHANCE OF SHOWERS AND STORMS ON THESE TWO
DAYS AS WE WILL SEE THE MONSOON PLUME GET REINVIGORATED OVER THE
REGION AND A DISTURBANCE COMES ACROSS THE REGION.
IT APPEARS AN UNSETTLED PATTERN WILL REMAIN ACROSS THE REGION
THROUGH THE REST OF THE WEEK BRINGING IN SOME COOLER WEATHER AND
BETTER CHANCES OF PRECIP. \/HODANISH
