THE FORECAST PERIOD BEGINS WITH SURFACE HIGH PRESSURE OVER
MINNESOTA, MANITOBA AND ONTARIO. A MID-LEVEL RIDGE SITS OVER THE
MIDWEST INTO CANADA AND LOW PRESSURE IS CURRENTLY CENTERED OVER
CENTRAL CALIFORNIA. A MID-LEVEL SHORTWAVE TROUGH OVER NORTHERN TEXAS
AND SOUTHERN OKLAHOMA WILL LIFT NORTH INTO SOUTH CENTRAL KANSAS AND
NORTHERN OKLAHOMA THROUGH THE DAY FRIDAY. WARM, MOIST GULF AIR WILL
MOVE INTO THE REGION AS WELL. SHOWERS AND MAYBE A FEW THUNDERSTORMS
WILL BE POSSIBLE FOR AREAS MAINLY SOUTH OF INTERSTATE 80. SEVERE
WEATHER IS NOT EXPECTED AT THIS TIME.
AFTERNOON HIGH TEMPERATURES WILL REACH THE MID-80S NEAR THE KS/NE
BORDER TO THE UPPER 80S AND LOW 90S FOR AREAS ALONG AND NORTH OF I-
80. LOWS HEADING INTO THURSDAY NIGHT/FRIDAY MORNING WILL BE IN THE
UPPER 50S TO MID-60S.
FRIDAY, THE RIDGE PUSHES EASTWARD, EXTENDING NORTH OVER MANITOBA,
ONTARIO AND MINNESOTA, WHILE THE WESTWARD EXTENT OF IT SHIFTS INTO
WESTERN IOWA AND THE EASTERN PORTION OF THE DAKOTAS. THE CONTINUED
PRESENCE OF THE MID-LEVEL SHORTWAVE TROUGH OVER NORTH CENTRAL KANSAS
AND SOUTHEASTERN NEBRASKA WILL BRING ADDITIONAL SHOWER/THUNDERSTORM
CHANCES (20-40%) TO THE REGION ON FRIDAY. AREAS LUCKY ENOUGH TO
RECEIVE ANY RAINFALL MAY PICK UP A TENTH OR TWO, WITH SOME LOCALIZED
HIGHER AMOUNTS WITH ANY THUNDERSTORMS.
SATURDAY INTO THE EXTENDED FORECAST PERIOD: WE WILL SEE A PATTERN
SHIFT AS THE CLOSED MID-LEVEL LOW OVER CALIFORNIA WILL BEGIN PUSHING
TO THE EAST. AS THE LOW PUSHES EAST TOWARD THE FOUR CORNERS REGION,
IT IS EXPECTED TO OPEN INTO A BROAD TROUGH. SEVERAL SHORTWAVES
MOVING AROUND THE MAIN TROUGH WILL LIFT INTO NEBRASKA AND IOWA OVER
THE WEEKEND AND INTO NEXT WEEK. WITH MOISTURE ADVECTING INTO THE
REGION AND THE SHORTWAVES MOVING THROUGH, THERE WILL BE DAILY
CHANCES FOR SHOWERS/STORMS ACROSS AT LEAST A PORTION OF THE CWA
THROUGH EARLY NEXT WEEK. EXPECTED HIGH TEMPERATURES WILL BE IN THE
LOW TO MID-80S WHILE LOWS WILL RANGE FROM THE MID-50S TO MID-60S.
