AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
856 PM CDT WED APR 4 2012

.UPDATE...
INCREASED WINDS OVER AND ADJACENT TO LAKE SUPERIOR TONIGHT. KDYT
IS REPORTING A NE WIND SUSTAINED AT 16 KT. THE 18Z NAM/DLHWRF BOTH
HAVE PICKED UP ON THE INCREASED NE FLOW OVER LK SUP TONIGHT AND
SUGGEST IT PERSISTS OVERNIGHT AND THROUGH THE DAY THURSDAY. IN
RESPONSES TO THE ELEVATED ONSHORE FLOW OVERNIGHT...HAVE INCREASED
TEMPERATURES FOR LOCATIONS ALONG THE LAKESHORE.

&&

.PREV DISCUSSION... /ISSUED 632 PM CDT WED APR 4 2012/

AVIATION.../0Z TAF ISSUANCE/

VFR CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD. WINDS WILL BE
LIGHT TONIGHT AND BECOME SOUTHEASTERLY BY 15Z OVER THE WESTERN
AERODROMES. THE TERMINALS AT DLH AND HYR WILL HAVE EASTERLY WINDS
BY LATE THURSDAY MORNING.

PREV DISCUSSION... /ISSUED 314 PM CDT WED APR 4 2012/

SHORT TERM...THIS EVENING THROUGH THURSDAY NIGHT...
SHARP RIDGING ALOFT WILL CONTINUE AS STRONG SURFACE HIGH PRESSURE
BUILDS DOWN FROM HUDSON BAY INTO THE LAKE SUPERIOR BASIN. SO FAR
THE GRADIENT AND ONSHORE WINDS ARE WEAK SINCE THE HIGH HAS NOT HAD
A CHANCE TO BUILD UP STRONGLY OVER LAKE SUPERIOR. AIR ASSOCIATED
WITH THE HUDSON BAY IS ARCTIC...TEMPERATURES HAVE BEEN MODIFIED
BUT MOISTURE HAS NOT BEEN ADDED. SO...THE PERIOD WILL HAVE CLEAR
SKIES AND LARGE DAY TO NIGHT TEMPERATURE DIFFERENCES...ESPECIALLY
INLAND. DURING THURSDAY AFTERNOON AND EVENING...HIGH PRESSURE WILL
BECOME MORE ESTABLISHED AND DEEPER...AS SURFACE PRESSURES BEGIN TO
FALL TO OUR WEST. THIS WILL ACCELERATE ONSHORE WINDS BEGINNING
THURSDAY AFTERNOON AND CHILL AREAS NEAR LAKE SUPERIOR. EVEN DRIER
AIR WILL RESULT IN COLDER TEMPERATURES THURSDAY NIGHT AS COMPARED
TO TONIGHT.

LONG TERM...FRIDAY THROUGH NEXT THURSDAY...
THE NORTHLAND SHOULD END THE WORK WEEK WITH A RELATIVELY WARM AND
SUNNY DAY AS HIGH PRESSURE DOMINATES THE GREAT LAKES REGION. A
COLD FRONT IS PROJECTED TO MOVE THROUGH THE REGION EARLY THIS
WEEKEND...AND IT COULD BRING SHOWERS TO THE NORTHLAND LATE FRIDAY
NIGHT AND INTO SATURDAY NIGHT. THERE COULD BE ISOLATED THUNDER ON
SATURDAY. SHOWERS COULD LINGER SUNDAY INTO MONDAY AS THE UPPER
LEVEL LOW MOVES THROUGH THE REGION. THERE COULD BE PERIODS OF A
MIX OF RAIN AND SNOW AS THE COLDER AIR WRAPS IN BEHIND THE SYSTEM.

AVIATION...04/04/18Z ISSUANCE...
HIGH PRESSURE WILL CONTINUE TO PROVIDE SUNNY SKIES AND VFR
CONDITIONS ACROSS NE MN AND NW WI THROUGH TOMORROW AFTERNOON.
LIGHT NORTHEASTERLY WINDS WILL BECOME EASTERLY TONIGHT.
