AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
658 PM CDT THU MAY 24 2012

.UPDATE...HAVE JUST UPDATED TO CANCEL THE SEVERE THUNDERSTORM
WATCH FOR NW WI...AS THE THREAT HAS NOW MOVED OUT OF THE AREA.
THAT LEAVES SOME URBAN AND SMALL STREAM FLOOD ADVISORIES AND THE
RIVER FLOOD PRODUCTS. SHOWERS AND THUNDERSTORMS SHOULD CONTINUE TO
GRADUALLY WIND DOWN OVERNIGHT.

&&

.PREV DISCUSSION... /ISSUED 648 PM CDT THU MAY 24 2012/

AVIATION.../0Z TAF ISSUANCE/

BAND OF SHOWERS AND THUNDERSTORMS HAVE MOVED EAST OF THE
TERMINALS. ANY LINGERING SHOWERS WILL BE LIGHT AND END EARLY.
CEILINGS WILL DROP TO MVFR RANGE AROUND 06Z. HAVE INCLUDED SOME
PATCHY FOG AT BRD AND DLH. VISIBILITIES MAY OCCASIONALLY DROP TO
IFR RANGE. MIGHT NEED TO ADD OTHER TAF LOCATIONS FOR THE NEXT
FORECAST PERIOD. EXPECT VFR CONDITIONS AFTER 14Z ACROSS ALL THE
AERODROMES.

PREV DISCUSSION... /ISSUED 636 PM CDT THU MAY 24 2012/

HAVE JUST UPDATED TO REMOVE THE WIND ADVISORY THAT WAS
IN EFFECT FOR IRON AND PRICE COUNTIES THROUGH 6 PM. HAVE ALSO
OPTED TO REMOVE THE FLOOD WATCH THAT WAS IN EFFECT FOR MUCH OF
EC AND NE MN THROUGH 7 PM. WE WILL CONTINUE TO HAVE SOME ISSUES
WITH ROAD CLOSURES DUE TO WASHOUTS AND WATER COVERED ROADS UNTIL
THE WATER SUBSIDES...BUT THE THREAT OF WHOLESALE AREAL FLOODING
HAS DIMINISHED. AS A RESULT...WE DID CANCEL THE FLOOD WATCH. URBAN
AND SMALL STREAM FLOOD ADVISORIES REMAIN IN EFFECT AT THIS TIME
AND WE HAVE JUST RECEIVED NEW REPORTS OF SOME ROAD CLOSURES IN
DOUGLAS COUNTY. TRIED TO STRESS THE IMPORTANCE OF DRIVING WITH
CAUTION AS NIGHT APPROACHES...AS SOME LESSER TRAVELED ROADS AND
DRIVEWAYS MAY NOT HAVE BEEN DISCOVERED OR REPORTED YET. DRIVING AT
NIGHT AFTER FLOODING WILL BE A THREAT OVERNIGHT FOR THIS REASON.
THE SEVERE THREAT WAS GRADUALLY DIMINISHING ACROSS NW WI...AND
HAVE PULLED FOUR COUNTIES OUT OF THE WATCH. THAT LEAVES IRON AND
PRICE COUNTIES IN THE WATCH.

PREV DISCUSSION... /ISSUED 417 PM CDT THU MAY 24 2012/

SHORT TERM...TWO MAJOR CONCERNS FOR THE SHORT TERM...FLOODING AND
SEVERE WEATHER.

AT 4 PM...NUMEROUS SHOWERS AND THUNDERSTORMS CONTINUED TO MOVE
THROUGH THE AREA. WE HAD SEEN SOME LOCALIZED FLOODING ACROSS THE
INTERSTATE 35 CORRIDOR UP TO DULUTH. IT LOOKS LIKE THE HEAVIEST
RAINFALL REPORT SO FAR WAS 4 INCHES NEAR HINCKLEY. COULD STILL SEE
SOME RISES THROUGH THE EVENING...AND WE HAVE ISSUED AN URBAN AND
SMALL STREAM FLOOD ADVISORY THROUGH 9 PM. WE ALSO HAVE THE FLOOD
WATCH CONTINUING THROUGH 7 PM. OF OTHER CONCERN IS THE POTENTIAL
FOR SEVERE THUNDERSTORMS IN NORTHERN WISCONSIN. THE STORMS WERE
GENERALLY NOT SEVERE AS OF 4 PM...BUT AS THE STORMS MOVE INTO THE
EASTERN COUNTIES...WE MAY SEE AN INCREASE IN SEVERE ACTIVITY YET
THIS EVENING. TEMPERATURES IN KPBH WERE IN THE MID 80S...WITH WIND
GUSTS INTO THE 45 MPH RANGE MIXING DOWN DUE TO PARTIAL SUNSHINE.
WILL ALSO CONTINUE THE WIND ADVISORY IN THE EASTERN TWO ZONES
THROUGH 6 PM.

AGAIN FOR TONIGHT...THE NEXT SEVERAL HOURS WILL BE MOST
DICEY...MONITORING THE SEVERE THREAT IN NORTHERN WISCONSIN AND THE
FLOODING POTENTIAL ELSEWHERE.

THE SHOWERS AND THUNDERSTORMS WILL PULL OFF TO THE NORTH AND EAST
OVERNIGHT...WITH JUST SOME LINGERING SHOWERS ACROSS THE NORTH ON
FRIDAY.

RETURN FLOW ALREADY BEGINS BY FRIDAY NIGHT...WITH SHOWERS AND
THUNDERSTORMS DEVELOPING ACROSS SOUTHERN MINNESOTA AND WISCONSIN
NORTH OF A WARM FRONT NEAR THE IOWA BORDER.

LONG TERM...[SATURDAY - WEDNESDAY]

THIS WEEKEND IS LOOKING WET AS LOW PRESSURE MOVES INTO THE NORTHERN
PLAINS AND A WARM FRONT LIFTS INTO THE UPPER MIDWEST. THE NORTHLAND
WILL LIKELY GET RAIN SHOWERS SATURDAY NIGHT...MAYBE SOME THUNDER
ACROSS THE SOUTHERN FA. SUNDAY AND SUNDAY NIGHT LOOK MUCH MORE
ACTIVE...WITH POTENTIAL SEVERE WEATHER...AS A WARM FRONT LIFTS INTO
THE NORTHLAND. THERE SHOULD THEN BE A COOLING TREND MONDAY AND
TUESDAY ALONG WITH POTENTIAL LIGHT RAIN SHOWERS AS COOL WESTERLY
FLOW DEVELOPS IN THE WAKE OF A PASSING LOW PRESSURE SYSTEM. THE
MODELS LOSE AGREEMENT FOR WEDNESDAY...BUT HIGH PRESSURE MAY PROVIDE
DRY WEATHER FOR THE NORTHLAND.
