NWS Duluth, MN wrote its last area forecast discussion before this flash flood warning went out at Jun 27, 2:45 PM CDT, 5 hours 34 minutes earlier.

Area forecast discussion, Jun 27, 2:45 PM CDT, 5 hours 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
245 PM CDT MON JUN 27 2011

.DISCUSSION...THIS EVENING THROUGH THURSDAY...
SURFACE LOW PRESSURE IS NOW OVER THE TIP OF BAYFIELD PENINSULA AND
ITS COLD FRONT EXTENDS SOUTH...THROUGH THE HAYWARD AREA. SHOWERS
AND THUNDERSTORMS ASSOCIATED WITH THE LOW ARE LEAVING THE EASTERN
ARROWHEAD AND MOVING THROUGH NORTHWEST WISCONSIN. EARLIER VERY
HEAVY RAIN...ASSOCIATED WITH THIS SYSTEM...HAS MOVED INTO ONTARIO.
VERY RAPID COOLING ALOFT...ASSOCIATED WITH AN UPPER LOW...HAS
BROUGHT THE FREEZING LEVEL DOWN TO ABOUT 6500 FEET OVER THE RED
RIVER VALLEY. THIS RAPID MID-LEVEL COOLING HAS ALLOWED LIGHT
SHOWERS TO FORM...ALL THE WAY BACK TO CENTRAL NORTH DAKOTA. THE
COLD COLUMN HAS GREATLY LIMITED THE POTENTIAL FOR EITHER THUNDER
OR SUBSTANTIAL RAIN. IN LIGHT OF THE COOLING...WE LEFT SHOWERS IN
ACROSS OUR AREA THIS EVENING AND PUT ISOLATED LIGHT SHOWERS EAST
OF THE IRON RANGE LATE TONIGHT. WITH THE ONSET OF AN UPPER RIDGE
AND ITS ASSOCIATED HIGH-LEVEL WARMING...ALONG WITH LOW LEVEL COLD
ADVECTION...SKIES WILL CLEAR QUICKLY TUESDAY MORNING. THE RETURN
FLOW BEHING A SURFACE HIGH WILL BRING WARMING LATE WEDNESDAY AND
THURSDAY. WITH MID AND UPPER LEVEL OF A WARM MOIST AIR MASS...WE
ANTICIPATE ISOLATED SHOWERS WEDNESDAY NIGHT AND THURSDAY. AN
IMPORTANT WARMING TREND SHOULD BEGIN HERE THURSDAY.

.EXTENDED...THURSDAY NIGHT THROUGH NEXT MONDAY...
WARM TEMPERATURES AND DRY CONDITIONS WILL BE PRESENT ACROSS THE
NORTHLAND FOR THE EARLY PART OF THE EXTENDED AS A RIDGE OF HIGH
PRESSURE DOMINATES THE REGION. AFTERNOON HIGH TEMPERATURES WILL SOAR
INTO THE 80S...WITH A FEW PLACES IN NW WI APPROACHING 90 ON FRIDAY.
CONDITIONS WILL BE RELATIVELY HUMID AS WELL FOR THIS REGION...AND
ALLOW TEMPS TO FEEL MUCH WARMER THAN THE ACTUAL AIR TEMP. THERE IS A
CHANCE OF SOME CONVECTIVE SHOWERS AND STORMS ACROSS THE NRN TIER
COUNTIES ON FRI AFTERNOON AS AN UPPER LEVEL WAVE RIDES N OF THE
RIDGE AND ALLOWS FOR ENOUGH FORCING TO TRIGGER SOME CONVECTION. A
SFC HIGH PRESSURE BUILDS IN OVER THE UPPER MIDWEST ON SAT AND
SUN...WITH HIGHS IN THE UPPER 70S AND LOWER 80S AND MOSTLY SUNNY
SKIES. ANOTHER WEAK SYSTEM PUSHES IN FROM THE WEST LATE SUN/EARLY
MON AND BRINGS WITH IT ANOTHER CHANCE FOR A FEW SHOWERS AND T-STORMS.

.AVIATION...06/27/18Z ISSUANCE...
AREA OF LOW PRESSURE AND SFC FRONT CURRENTLY MOVING THROUGH THE
NORTHLAND AND PRODUCING MAINLY MVFR CIGS/VSBYS...WITH SCT RAIN
SHOWERS AND A FEW ISOLATED THUNDERSTORMS. THE MORNING ROUND OF SHRA
AND TSRA IS STILL MOVING THROUGH THE TIP OF THE ARROWHEAD AND THERE
ARE A FEW STORM CELLS REGENERATING OVER NW WI. THESE WILL MAINTAIN
THEIR INTENSITY OR WEAKEN SLIGHTLY THROUGH 00Z. ADDITIONAL LIGHT
RAIN SHOWERS WITH A FEW ISOLATED T-STORMS WILL REDEVELOP FURTHER TO
THE WEST LATE THIS AFTERNOON AND EARLY EVENING AND IMPACT TERMINALS
IN THE AREA THROUGH 02-04Z. A FEW GUSTS UP TO 20 KT FROM THE NNW ARE
POSSIBLE THIS AFTERNOON...OTHERWISE WINDS WILL REMAIN AROUND 5-10KTS
FROM THE NW THROUGH TONIGHT. CLOUDS WILL SCATTER OUT BY LATE TONIGHT
WITH SKC EXPECTED FOR ALL TERMINALS BY TOMORROW MORNING.
