ISSUED EARLIER THAN USUAL IN ANTICIPATION FOR TODAY/S SEVERE WEATHER
EVENT.

THE LAST DAY OF SEVERE WEATHER IS EXPECTED THIS AFTERNOON AND
EVENING BEFORE QUIETER WEATHER RETURNS TO THE CWA TOMORROW AND THE
WEEKEND. WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL TROUGH ACROSS
CENTRAL MONTANA MOVING EASTWARD. SURFACE ANALYSIS PLACES A SURFACE
LOW NEAR THE SE WY/NE CO BORDER WITH A TROUGH EXTENDING NORTHWARD
INTO EASTERN MONTANA. SOUTHEASTERLY WINDS CONTINUE TO BRING MOISTURE
RICH AIR INTO THE CWA WITH DEWPOINTS IN THE UPPER 50S TO MID 60S.

CONTINUING TO WARM INTO THE MID 80S TO LOWER 90S. INSTABILITY WILL
ALSO INCREASE THIS AFTERNOON WITH MODELS SHOWING ANYWHERE FROM 1500
TO 4000 K/JG. PLENTY OF SHEAR AVAILABLE FOR SUPERCELLS TO DEVELOP
TODAY. REGIONAL RADAR/SATELLITE SHOW SEVERE STORMS QUICKLY
DEVELOPING ACROSS NORTHEAST MONTANA EARLY THIS AFTERNOON ALONG THE

BRINGING STORMS ACROSS NORTHEAST WYOMING...THE BLACK HILLS...AND
NORTHWEST SOUTH DAKOTA. ACTIVITY SHOULD BE IN FULL SWING BY MID
AFTERNOON AS TOWERING CU ARE ALREADY DEVELOPING OVER THE NORTHERN
BLACK HILLS. THE CONVECTION WILL CONTINUE SOUTHEAST FOR THE EVENING
AFFECTING THE CENTRAL/SOUTHERN HILLS THROUGH SOUTH CENTRAL SOUTH
DAKOTA. WITH THE LARGE AMOUNTS OF INSTABILITY...THE MAIN THREATS
WILL BE VERY LARGE HAIL. DAMAGING WINDS AND ISOLATED TORNADOES WILL
ALSO BE A THREAT TONIGHT...THOUGH TO A LESSER DEGREE THAN THE HAIL.
EITHER WAY...IT LOOKS TO BE BUSY AFTERNOON AND EVENING. THE ACTUAL
COLD FRONT WILL BE DELAYED...CROSSING THE AREA FROM AROUND 06Z TO
12Z.

A SHORTWAVE WILL MOVE ACROSS SOUTH CENTRAL CANADA TOMORROW AND INTO
NORTHERN PORTIONS OF THE NORTHERN PLAINS. COOLER AIR WILL CONTINUE

SOUTHERN SD. WILL KEEP SOME LOW CHANCES FOR SHOWERS AND STORMS
DURING THE DAY WITH STEEP LAPSE RATES AND COLD AIR ALOFT. DRY LOW
LEVELS SHOULD KEEP ACTIVITY ISOLATED AND ON THE LIGHT SIDE. DRY AND
SEASONABLY MILD WEATHER IS EXPECTED FOR SATURDAY WITH HIGHS IN THE
70S AND LOWER 80S.

EXTENDED...UPPER RIDGE WILL REMAIN OVER THE WESTERN CONUS ON SUNDAY
BRINGING VERY WARM AND DRY CONDITIONS TO THE AREA. THE RIDGE AXIS
WILL REMAIN OVER THE ROCKIES FOR THE BEGINNING OF THE WORK WEEK WITH
WEAK DISTURBANCES MOVING THROUGH...BRINGING A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS TO PARTS OF THE AREA. RIDGE STARTS
FLATTENING OUT TOWARDS MID-WEEK...BRINGING A BETTER CHANCE OF
PRECIPITATION.
