.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 315 AM CDT SUN SEP 21 2014

AT 3 AM...NUMEROUS SHOWERS CONTINUED ACROSS MUCH OF THE CWA. THE
RAIN WAS GRADUALLY ENDING ACROSS THE INTERNATIONAL BORDER REGION
AND IT WAS DRY IN AND AROUND BRAINERD. OTHERWISE MUCH OF THE REST
OF THE AREA WAS SEEING RAIN. TEMPERATURES RANGED FROM THE MID 40S
IN THE ARROWHEAD TO THE 50S ELSEWHERE.

THE MAIN FOCUS FOR TODAY WILL BE TIMING AND COVERAGE OF RAINFALL
THIS MORNING...AND CLOUD COVER AND HIGH TEMPS FOR THIS AFTERNOON.
THE H5 UPPER LEVEL LOW WILL CONTINUE TO PULL OFF TO THE SOUTH AND
EAST AS THE DAY WEARS ON...AND THE ELONGATED TROUGH EXTENDING TO
THE NORTH AND WEST OF THE LOW WILL GRADUALLY SAG SOUTHWARD AS
WELL. WILL TREND TOWARD A DRY FORECAST BY MIDDAY...ALTHOUGH A FEW
OF THE HIGH RESOLUTION MODELS INDICATE THE POTENTIAL FOR AN
ISOLATED SHOWER TO LINGER INTO EARLY AFTERNOON. CLOUDS WILL
GRADUALLY DECREASE FROM NORTH TO SOUTH AS WELL...BUT MAY BE A BIT
STUBBORN IN SPOTS...ESPECIALLY IN THE WESTERN AND SOUTHERN CWA. HIGH
TEMPERATURES WILL GENERALLY BE IN THE 60S.

CLOUDS WILL CONTINUE TO BREAK UP TONIGHT...WITH LOWS GENERALLY IN
THE 40S UNDER MOSTLY CLEAR TO PARTLY CLOUDY SKIES.

MONDAY WILL BE WARMER THAN NORMAL WITH A WESTERLY WIND. HIGHS WILL
GENERALLY BE IN THE LOWER 70S WITH PLENTY OF SUNSHINE. H85 TEMPS
ON MONDAY AFTERNOON WILL REACH AS HIGH AS 12C.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 315 AM CDT SUN SEP 21 2014

THE NORTHLAND CAN EXPECT WARM WEATHER THIS WEEK DUE TO SOUTHERLY
FLOW AND UPPER LEVEL RIDGING OVER THE NORTHLAND THROUGH MUCH OF THE
PERIOD. HIGH PRESSURE OVER THE NE UNITED SATES WILL HELP MAINTAIN
DRY WEATHER. THE EXCEPTION IS WEDNESDAY AND WEDNESDAY NIGHT WHEN AN
UPPER LEVEL TROUGH IN THE NORTHERN PLAINS COULD HELP DEVELOP SOME
SHOWERS AND STORMS OVER THE NORTHERN PLAINS AND THE NORTHLAND.

TEMPERATURES WILL LIKELY BE ABOUT 5 TO 10 DEGREES ABOVE NORMAL. THE
WARMEST STRETCH OF WEATHER WILL LIKELY BE LATE THIS WEEK AND OVER
THE WEEKEND. HIGHS ON FRIDAY AND SATURDAY SHOULD BE IN THE LOWER 70S.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1220 PM CDT SUN SEP 21 2014

WEAK TRAILING UPPER WAVE WILL EXIT THE REGION TO THE SE TODAY BUT
ALLOW THE MID LEVEL VFR/MVFR CLOUD COVER TO PERSIST THROUGH THE
AFTERNOON. HIGH PRESSURE WILL BUILD IN TONIGHT AND ALLOW DRIER AIR
TO MIX IN...ALONG WITH LIGHT WINDS. CONDITIONS WILL BECOME
FAVORABLE FOR FOG TONIGHT AND EARLY MON MORNING. STILL SOME
UNCERTAINTY REGARDING THE TIMING AND AREAL EXTENT OF THE FOG...SO
JUST WENT WITH TEMPO GRPS AT ALL TERMINALS. VFR CONDITIONS WILL
RETURN BY LATE MON MORNING.
