SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
352 AM EDT SAT AUG 27 2016

VALID 12Z SAT AUG 27 2016 - 12Z MON AUG 29 2016

...SHOWERS AND THUNDERSTORMS EXPECTED ACROSS THE CENTRAL PLAINS
AND MIDWEST...

...HOT AND HUMID CONDITIONS CONTINUE ACROSS MUCH OF THE SOUTHERN
AND EASTERN STATES...

...WARM AND DRY FOR THE WEST COAST STATES...

THE SHORT-RANGE FORECAST PERIOD WILL BE FEATURED WITH A
PROGRESSIVE FLOW PATTERN ACROSS THE NORTHERN TIER OF THE U.S. AND
ACROSS SOUTHERN CANADA, AND A SLOWLY WEAKENING UPPER LEVEL RIDGE
OVER THE CENTRAL AND EASTERN U.S. THAT REMAINS ANCHORED IN PLACE
THROUGH THE WEEKEND.  ON SATURDAY, A SHORTWAVE DISTURBANCE ALOFT
IS FORECAST TO TRACK EASTWARD FROM MONTANA TO MINNESOTA BEFORE
LIFTING NORTHWARD OVER CANADA, AND THIS WILL BE THE MAIN WEATHER
MAKER ACROSS THE NATION`S MID-SECTION OVER THE WEEKEND.

MULTIPLE ROUNDS OF SHOWER AND THUNDERSTORM ACTIVITY ARE LIKELY
FROM OKLAHOMA TO THE NORTHERN GREAT LAKES THROUGH SATURDAY NIGHT
AS A WARM FRONT LIFTS NORTHWARD AHEAD OF THE SHORTWAVE
DISTURBANCE.  THE POTENTIAL EXISTS FOR 1 TO 2 INCHES OF RAINFALL,
WITH THE GREATEST AMOUNTS LIKELY ACROSS NORTHERN OKLAHOMA AND
EASTERN KANSAS.  A FEW SEVERE STORMS WILL ALSO BE POSSIBLE.
ADDITIONAL STORMINESS IS EXPECTED ACROSS THE CENTRAL GULF COAST
AND THE FLORIDA, ESPECIALLY DURING THE AFTERNOONS AND EVENINGS.
TOWARDS THE END OF THE SHORT-RANGE PERIOD ON MONDAY MORNING, A
COLD FRONT IS EXPECTED TO SINK SOUTHWARD OVER THE NORTHERN PLAINS
AND BRING COOLER WEATHER TO THE REGION.

IN THE TEMPERATURE DEPARTMENT, EXPECT THE LATE-SUMMER HEAT AND
HUMIDITY TO CONTINUE ACROSS MUCH OF THE CENTRAL AND EASTERN U.S.
THROUGH THE WEEKEND, WITH WIDESPREAD HIGHS IN THE UPPER 80S TO MID
90S, AND LOWS IN THE 70S.  SOME LOCATIONS MAY GET CLOSE TO HEAT
ADVISORY CRITERIA AT TIMES, BUT NOT AS INTENSE AS THE HEAT WAS
EARLIER THIS MONTH.  OUT WEST, IT SHOULD REMAIN DRY AND WARM, WITH
NO APPRECIABLE CHANCE OF RAINFALL FOR WASHINGTON, OREGON, AND
CALIFORNIA.  SOME DIURNAL SHOWERS AND THUNDERSTORMS WILL CONTINUE
TO BE POSSIBLE ACROSS THE FOUR-CORNERS REGION.
