AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DULUTH MN
837 AM CDT SAT OCT 15 2011

.UPDATE...
RECEIVED REPORT OF FLURRIES UP ON THE GUNFLINT TRAIL AND KCKC WAS
ALSO REPORTING SOME LIGHT SNOW SHOWERS. ALSO NOTED ON WEBCAM. THESE
WERE COMING FROM LOW CLOUD DECK.

&&

.PREV DISCUSSION... /ISSUED 621 AM CDT SAT OCT 15 2011/

AVIATION...12Z TAF ISSUANCE...

VFR CONDITIONS THROUGH TODAY AND EARLY THIS EVENING AS AN UPPER
TROUGH OVER THE CNTRL/ERN GREAT LAKES CONTINUES TO SLIDE TO THE
EAST...AND WEAK HIGH PRESSURE BUILDS IN. MAIN CONCERNS WILL BE ON
THE GUSTY NW WINDS THROUGH THIS AFTERNOON...LLWS THIS MORNING...AND
A CHC FOR MVFR CIGS/VSBYS LATE TONIGHT. AFTER 03Z TONIGHT...A WEAK
UPPER S/W SLIDES INTO NW MN ALONG WITH A DEEPER MOIST LAYER AND A
LOW/MID CLOUD DECK. IF ENOUGH COOLING OCCURS BEFORE THE MID DECK
ROLLS IN AND WINDS DIMINISH SUBSTANTIALLY...THEN THERE IS ALSO THE
CHC FOR SOME LIGHT FOG FROM BRD TO HIB TO HYR AFTER MIDNIGHT
TONIGHT.

PREV DISCUSSION... /ISSUED 244 AM CDT SAT OCT 15 2011/

SHORT TERM...TODAY THROUGH SATURDAY...
CURRENT WV SAY IMAGERY SHOWS ELONGATED TROUGH EXTENDING FROM
MANITOBA/OVER THE GREAT LAKES. A DEEPENING LOW AT THE BASE OF THE
TROUGH WILL LIFT NORTH OVER ONTARIO THROUGH THE DAY. MODELS IN
AGREEMENT THAT THE LOW BECOMES VERTICALLY STACKED OVER SOUTHERN
HUDSON BAY SAT NIGHT/SUNDAY WHILE PHASING WITH A SECONDARY LOW/H50
VORT MAX THAT IS CURRENTLY RESIDING IN NRN MANITOBA. THE NEARLY
STATIONARY LOW WILL KEEP A TIGHT PRESSURE GRADIENT AND PERSISTENT
GUSTY WEST TO NORTHWEST FLOW OVER THE WESTERN GREAT LAKES REGION
THROUGH THE WEEKEND. COOL H85-H70 TEMPS WILL ALLOW FOR GOOD
AFTERNOON MIXING AND 30-35 KT WINDS FOUND AT H92 TO HAVE NO PROBLEM
MAKING IT TO THE SFC TODAY AND AGAIN ON SUNDAY.

A VORT MAX WILL DROP QUICKLY SE OVER THE FA SUNDAY IN THE 70 KT H50
CYCLONIC FLOW. LATEST NAM BUFR SOUNDINGS SHOWING GOOD LAPSE RATES
AND UNSTABLE PROFILES WITH 200-300 J/KG OF CAPE ACROSS CWA.
HOWEVER...LIMITING FACTOR FOR SHRA WILL BE AVAILABLE MOISTURE
WITH MODELS SUGGESTING MOST AREAS REMAIN DRY. ATTM...BEST SHOT WILL
BE OVER THE WIS AREAS SUNDAY WHERE INTRODUCED A SMALL POP.

EXTENDED DISCUSSION...SUNDAY NIGHT THROUGH FRIDAY...

ACTIVE WEATHER PATTERN EARLY THIS WEEK WITH A DOMINANT COLD NWLY FLOW
PRODUCING PERIODS OF RAIN SHOWERS DURING THE DAY...AND EITHER
RAIN/SNOW MIX OR ALL SNOW DURING THE OVERNIGHT HOURS. ALL MEDIUM AND
LONG RANGE MODELS ARE IN FAIRLY GOOD AGREEMENT WRAPPING UP A STRONG
UPPER LOW OVER ONTARIO FROM SUNDAY TO TUESDAY THIS WEEK. THIS SYSTEM
WILL ALLOW COLD CANADIAN AIR TO BE USHERED IN FROM THE N DURING THIS
TIME ALONG WITH CHANCES FOR PRECIP OVER MUCH OF THE NORTHLAND MON
AND TUE. AN UPPER S/W AND ASSOCIATED 500MB VORT MAX WILL ROTATE
AROUND THE BACKSIDE OF THE MAIN UPPER LOW AND DROP INTO THE REGION
AND BRING A CHANCE FOR SOME RAIN AND OR RAIN/SNOW MIX DURING THE DAY
MONDAY. A COLD AIR MASS ALOFT WILL ACCOMPANY THIS WEAK DISTURBANCE
AND ALLOW FOR A CHC/SLGT CHC OF ALL SNOW MON NIGHT. LITTLE IF ANY
ACCUMULATION IS EXPECTED AT THIS TIME. THE COLD CONVECTIVE
CONDITIONS CONTINUE INTO TUE...BUT SLIGHT DAYTIME HEATING SHOULD
CHANGE OVER THE MORNING PRECIP TO A RAIN/SNOW MIX...AND ALL RAIN BY
THE AFTERNOON. THE FOCUS THEN SHIFTS TO THE GOGEBIC RANGE IN NW WI
WHERE A PERIOD OF LAKE EFFECT RAIN/SNOW SHOWERS WILL DEVELOP TUE
NIGHT THROUGH WED AFTERNOON. THE COLD AIR ALOFT OVER THE WARM LAKE
SURFACE...WITH A FAVORABLE NNWLY FETCH WILL PRODUCE MAINLY RAIN NEAR
THE SHORE...WITH RAIN/SNOW MIX INLAND THROUGH WED AFTERNOON. HIGH
PRESSURE BUILDS IN BY THURSDAY AND ALLOWS DRY CONDITIONS AND
SLIGHTLY WARMER TEMPS TO BE THE MAIN STORY THROUGH THE LATTER PART
OF THE WEEK. HIGHS IN THE 40S AND 50S...WITH OVERNIGHT LOWS IN THE
20S AND 30S ARE EXPECTED THROUGH THE EXTENDED PERIOD.
