THE FORECAST PERIOD STARTS OUT WITH A SHORTWAVE TROUGH SLIDING
SOUTHEAST ACROSS THE REGION AND AN UPPER RIDGE IN PLACE OVER THE
ROCKIES. RADAR SHOWS A FEW SHOWERS SCATTERED SHOWERS BETWEEN NORFOLK
AND FAIRBURY. THERE IS A 15-20% CHANCE OF A FEW ISOLATED SHOWERS AND
THUNDERSTORMS FOR THE REST OF THE AFTERNOON INTO THIS EVENING. LATE
THIS EVENING INTO TONIGHT, THUNDERSTORM CHANCES INCREASE (40-60%),
PARTICULARLY FOR AREAS ALONG AND SOUTH OF I-80. A FEW OF THESE
STORMS MAY BECOME STRONG WITH HAIL AND GUSTY WINDS POSSIBLE.
PRECIPITABLE WATER (PWAT) VALUES CURRENTLY RANGE FROM AROUND 1-1.4
INCHES. EXPECT (PWAT) VALUES TO INCREASE TO AROUND 1.5 INCHES THIS
EVENING INTO TONIGHT AS A MOISTURE PLUME BRINGS ADDITIONAL MOISTURE
TO THE AREA. WITH THUNDERSTORM POTENTIAL AND HIGHER PWAT VALUES,
THERE IS A POTENTIAL FOR SOME LOCALIZED FLOODING BETWEEN LATE
TONIGHT AND TUESDAY MORNING.
TUESDAY MORNING, SHOWERS AND STORMS WILL GRADUALLY END WEST TO EAST.
THE RIDGE WILL SHIFT EAST TUESDAY AND WEDNESDAY. DRY CONDITIONS ARE
EXPECTED TUESDAY AFTERNOON THROUGH WEDNESDAY. AFTERNOON HIGH
TEMPERATURES WILL RETURN TO THE 80S BOTH DAYS. LOWS WILL BE IN THE
50S AND 60S.
CHANCES (15-30%) FOR A FEW STORMS RETURN WEDNESDAY EVENING THROUGH
THURSDAY MORNING FOR PORTIONS OF THE AREA AS A WEAK SHORTWAVE
ARRIVES. RAIN CHANCES CLEAR OUT AGAIN IN THE AFTERNOON. THURSDAY
THROUGH THE WEEKEND, THE RIDGE WILL REMAIN OVER THE REGION WITH A
FEW SHORTWAVES MOVING THROUGH IT. HIGHS WILL GENERALLY BE IN THE 80S
WITH LOWS IN THE 60S. FRIDAY EVENING THROUGH THE END OF THE WEEKEND,
THERE WILL BE PERIODIC CHANCES FOR SHOWERS AND STORMS.
