NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1036 PM CDT WED MAY 15 2013

.UPDATE...

UPDATED FOR THE 06Z AVIATION DISCUSSION BELOW.

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 157 PM CDT WED MAY 15 2013

LAST BANDS OF -SHRA/SPRINKLES HAVE MOVED ALONG THE IA/MN BORDER
THIS AFTN...WITH SOME LIGHT SHOWER ACTIVITY ALONG THE SD/ND
BORDER. THIS ACTIVITY ACROSS ND/SD MAY AFFECT PORTIONS OF WC/SW MN
DURING THE LATE AFTN/EARLY EVENING HRS WITH -SHRA...BUT DUE TO THE
RELATIVELY DRY AIR MASS IN PLACE...AND LIMITED INSTABILITY...WILL
LEFT OUT FOR NOW. WILL SEE HOW REGIONAL RADAR INDICATES IF WE NEED
TO ADD TO CURRENT GRIDS. OTHERWISE...DRY WX WILL PREVAIL THRU
THURSDAY AFTN WITH A BACKDOOR COLD FRONT MOVING IN FROM THE NE
OVERNIGHT. THIS WILL LEAD TO COOLER TEMPS IN THE NE FA...WITH NEAR
80 OR ABV IN THE SW. LATE AFTN/THURSDAY EVENING SHRA ACTIVITY WILL
BE DEPEND ON HOW FAR THE DRIER NE/E FLOW DEVELOPS BEHIND THIS COLD
FRONT LATE TONIGHT. ONCE THE FLOW BECOMES MORE SE...A MUCH BETTER
CHC OF SHRA/TSRA WILL DEVELOP.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 255 PM CDT WED MAY 15 2013

THE OVERALL WEATHER PATTERN STILL LOOKS TO BECOME AMPLIFIED
THURSDAY NIGHT THROUGH THE WEEKEND WITH AN ACTIVE PATTERN SETTING
UP ACROSS THE MIDWEST AS A SURFACE CYCLONE DEVELOPS ON THE LEE OF
THE ROCKIES WHILE THE UPPER TROUGH DIGS SOUTH ACROSS THE ROCKY
MOUNTAINS THROUGH SUNDAY. ACROSS OUR FA...THE UPPER RIDGE WILL
BUILD ON SATURDAY AND THE BEST PRECIPITATION CHANCES LOOK TO BE
ALONG AND NORTH OF CENTRAL MN THROUGH NORTHWESTERN WI. FROM SUNDAY
INTO MONDAY...THE SURFACE LOW WILL MOVE NORTH FROM KANSAS INTO
SOUTH DAKOTA...DRAGGING A WARM FRONT THROUGH SOUTHERN MN SETTING
THE STAGE FOR A WET FINISH TO THE WEEKEND. THERE IS POTENTIAL TO
HAVE SEVERE THUNDERSTORMS...ESPECIALLY ACROSS SOUTHERN MN...BUT
THE BEST SEVERE POTENTIAL LOOKS TO REMAINS SOUTH OF OUR AREA AS
THE BEST CAPE AND SHEAR REMAINS THERE. FROM MONDAY THROUGH
WEDNESDAY...THE UPPER TROUGH BECOMES A CUT OFF LOW THAT STALLS OUT
ACROSS THE UPPER MIDWEST WHICH WILL LIKELY CONTINUE TO PRODUCE
SHOWERS ACROSS THE AREA. AT THE END OF THE TIME PERIOD...A POLAR
HIGH LOOKS TO MOVE IN AND PROVIDE DRY CONDITIONS.
