.SHORT TERM...(TODAY THROUGH WEDNESDAY AFTERNOON)
ISSUED AT 313 AM CDT MON AUG 31 2015

A FEW WEAK RETURNS ON RADAR THIS AM AS A SHORTWAVE LIFTS OUT OF
NORTH DAKOTA. HAVING PASSED OVER KMBG WITHOUT A
CEILING...EXPECTATION IS MOST OF THESE RETURNS WILL END UP AS
NOTHING MORE THEN SPRINKLES...SO WILL MAINTAIN A 20 POP THROUGH THE
DAY AS THE WAVE/FRONT CONTINUE EAST. GUSTY WINDS AHEAD AND BEHIND
THE FRONT WILL CONTINUE THIS AM...BUT AS THE GRADIENT IS EXPECTED TO
WEAKEN...ANTICIPATE WINDS BY MID DAY WILL BE SIGNIFICANTLY LESS
INTENSE. FOR THE REST OF THE PERIOD...FLOW ALOFT IS
SOUTHWESTERLY...SO WE MAY CONTINUE TO SEE MID AND HIGH CLOUDS...BUT
A DEEP ELEVATED MIXED LAYER WILL KEEP US CAPPED. AS FOR
TEMPERATURES...WILL SEE GOOD MIXING TODAY SO HIGHS CAN STILL REACH
INTO THE 80S WITH MUCH LOWER HUMIDITY. SURFACE HIGH MOVES
OVERHEAD TONIGHT...WITH RETURN FLOW BRINGING BACK WARMER
TEMPERATURES AND INCREASING HUMIDITY LATE TUESDAY/WEDNESDAY.

.LONG TERM...(WEDNESDAY EVENING THROUGH SUNDAY)
ISSUED AT 313 AM CDT MON AUG 31 2015

THE EARLY PART OF THE EXTENDED PERIOD LOOKS DRY AS THE REGION WILL
BE SITUATED BETWEEN HIGH PRESSURE TO THE EAST AND APPROACHING LOW
PRESSURE TO THE WEST. THE LOW AND ASSOCIATED FRONTAL BOUNDARY REACH
THE CWA LATE THURSDAY NIGHT INTO FRIDAY...THEN STALLS OUT OVER THE
AREA. FAIRLY WARM TEMPERATURES IN THE MID LEVELS WILL LIKELY HINDER
PRECIPITATION DEVELOPMENT WHEN THE FRONT FIRST SETTLES IN...BUT WILL
THEN SEE BETTER CHANCES FRIDAY NIGHT INTO THE WEEKEND AS COOLER AIR
MOVES IN.

ABOVE NORMAL TEMPERATURES WILL START OFF THE PERIOD...WITH HIGHS IN
THE 80S AND 90S THURSDAY AND FRIDAY. THE COOLER AIR THEN MOVES WITH
HIGHS IN THE LOWER TO MID 80S SATURDAY AND IN THE 70S SATURDAY.
OVERNIGHT LOWS IN THE 60S WEDNESDAY NIGHT...THURSDAY NIGHT AND
FRIDAY NIGHT WILL GIVE WAY TO LOWS IN THE UPPER 40S AND 50S SATURDAY
NIGHT AND SUNDAY NIGHT.
