SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
242 AM EDT TUE JUL 25 2017

VALID 12Z TUE JUL 25 2017 - 12Z THU JUL 27 2017

...SEVERE WEATHER AND FLASH FLOODING POSSIBLE ACROSS THE NORTHERN
PLAINS TO THE UPPER MIDWEST ON TUESDAY AND WEDNESDAY...

...LOCALIZED FLOODING WILL BE A CONCERN FOR THE SOUTHWEST AND
SOUTHERN AND CENTRAL ROCKIES FOR THE NEXT FEW DAYS...

A COLD FRONT MOVING ACROSS THE NORTHERN TIER WILL BE THE FOCUS FOR
SHOWERS AND THUNDERSTORM FOR TUESDAY AND WEDNESDAY. HEAT AND
HUMIDITY BUILDING ACROSS THE NORTHERN PLAINS WILL INTERACT WITH
THE COLD FRONT TO GENERATE STRONG TO SEVERE STORMS FROM SOUTH
DAKOTA TO NORTHWEST WISCONSIN ON TUESDAY. LOCALLY HEAVY RAINFALL
FROM THESE STORMS COULD CAUSE SOME CONCERN FOR FLASH FLOODING
ACROSS THE REGION. MOISTURE WILL CONTINUE TO BUILD AHEAD OF THE
FRONTAL BOUNDARY AS IT PUSHES SOUTH AND EAST ACROSS THE CENTRAL
U.S. ON WEDNESDAY. THIS SHOULD FUEL ANOTHER ROUND OF STRONG TO
SEVERE STORMS THAT COULD BE MORE WIDESPREAD ACROSS THE UPPER
MIDWEST. HEAVY RAINFALL WILL ACCOMPANY THESE STORMS WITH FLASH
FLOOD POTENTIAL ACROSS IOWA AND ADJACENT STATES TO THE EAST.

WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE
ACROSS THE SOUTHWEST AND ROCKIES ON TUESDAY. LOCALLY HEAVY
RAINFALL COULD CAUSE FLASH FLOODING FROM THE CENTRAL ROCKIES TO
PARTS OF THE GREAT BASIN ON TUESDAY. THE ACTIVITY SHOULD BEGIN TO
SHIFT TO THE NORTH AND EAST AS THE UPPER LEVEL PATTERN LIFTS
TOWARD THE NORTHERN PLAINS. THE THREAT FOR FLASH FLOODING WILL BE
MORE FOCUSED OVER THE CENTRAL AND SOUTHERN ROCKIES FOR WEDNESDAY.

A DAY OF COOLER TEMPERATURES IS EXPECTED ACROSS THE NORTHEAST AND
NORTHERN MID ATLANTIC ON TUESDAY. THIS SHOULD BE ESPECIALLY
REFRESHING AFTER THE RECENT STRING OF HOT WEATHER. HIGH
TEMPERATURES COULD STRUGGLE TO BREAK 70 DEGREES ACROSS NEW
ENGLAND. HOT WEATHER IS EXPECTED ACROSS THE CENTRAL U.S. WITH
TEMPERATURES EXPECTED TO PEAK NEAR 100 DEGREES ACROSS SOME OF THE
CENTRAL AND NORTHERN PLAINS.
