.PREV DISCUSSION... /ISSUED 1224 AM CDT THU MAY 31 2012/

AVIATION...06Z TAF ISSUANCE...

OUTSIDE OF SOME PATCHY FOG BEFORE DAYBREAK...VFR CONDITIONS ARE EXPECTED
THROUGH THE NEXT 24 HOURS AS HIGH PRESSURE DOMINATES THE REGION.
HIGH CLOUDS ACROSS THE SRN TERMINALS WILL CONTINUE TO SPREAD
FURTHER SOUTH THROUGH THE OVERNIGHT. EXPECT A MID LEVEL CU FIELD
TO DEVELOP BY MID MORNING THURSDAY WITH SCT-BKN040 CIGS POSSIBLE.
CLOUDS SHOULD DISSIPATE BY LATE AFTERNOON/EARLY EVENING AND REMAIN
CLEAR INTO THE LATE EVENING THUR. WINDS WILL CONTINUE TO BE LIGHT
AND VARIABLE.

PREV DISCUSSION... /ISSUED 221 PM CDT WED MAY 30 2012/

SHORT TERM...MASSIVE CU FIELD COVERED THE FA AT 19Z...BUT SOME
EROSION WAS OCCURRING IN THE NW CORNER OF THE FA AS SFC HIGH WAS
WORKING ITS WAY ACROSS THE WESTERN GREAT LAKES AND NORTHERN
PLAINS. ADDITIONAL CLOUDS WERE ARRIVING FROM THE W FROM AN AREA OF
CONVECTION THAT WAS MOVING OVER THE DAKOTAS. EXPECT THIS CLOUD
COVER TO ERODE WITH THE LOSS OF DAYTIME HEATING. HOWEVER...UPPER
LEVEL TROF IS PROGGED TO DROP THROUGH THE FA TONIGHT. ALL MODELS
AGREE ON THIS AND CLOUDS MAY HANG ON A BIT LONGER OVER THE
SOUTHERN THIRD OF THE FA WHERE MODEL RH PROFILES SUGGEST MORE
MOISTURE/CLOUDS. AS SUCH...MIN TEMPS HAVE BEEN BUMPED UP. COLDEST
AIR IS PROGGED TO BE OVER NW WI BY 12Z THURSDAY WITH WEAK WAA OVER
THE REST OF THE FA. HAVE REMOVED THE MENTION OF WIDESPREAD FROST
AND HAVE PATCHY FROST WORDING MAINLY N OF HIGHWAY 2 IN MN AND E OF
HIGHWAY 63 IN NW WI AND AWAY FROM LAKE SUPERIOR FROM 09Z TO 12Z.

BAGGY UPPER LEVEL TROF WILL BE IN THE VCNY OF THE FA ON THURSDAY
WITH HIGH PRESSURE AT THE SFC. PCPN WILL BE WELL S OF THE AREA...BUT
CLOUDS WILL HANG AROUND THE SOUTHERN TIER OF THE FA.
REGARDLESS...MAX TEMPS WERE BUMPED UP WITH CONTINUING WAA.

THE AFOREMENTIONED BAGGY TROF MORPHS INTO A CLOSED LOW ALONG THE
LOWER GREAT LAKES WHILE ANOTHER UPPER TROF DROPS S OUT OF CANADA
TOWARDS THE NORTHERN PLAINS THURSDAY NIGHT. THIS WILL LEAVE THE FA
IN A COL PATTERN AND ONE MORE PERIOD OF QUIET WEATHER.

LONG TERM...[FRIDAY - TUESDAY]

FRIDAY SHOULD BEGIN WITH A LOW PRESSURE SYSTEM NEAR OHIO...HIGH
PRESSURE OVER THE UPPER MIDWEST...AND A TROUGH MOVING THROUGH THE
NORTHERN PLAINS. SUNNY SKIES MAY GREET THE NORTHLAND FRIDAY
MORNING...BUT THERE WILL LIKELY BE INCREASING CLOUD COVER FROM THE
WEST AS THE TROUGH MOVES THROUGH THE NORTHERN PLAINS TOWARDS THE FA.
CHANGED THE FRIDAY FORECAST TO DRY SINCE THE GFS/ECMWF/GEM/NAM
GENERALLY KEEP PCPN ASSOCIATED WITH THE TROUGH WEST OF THE FA.
FRIDAY NIGHT THROUGH THE WEEKEND COULD SEE SHOWERS AND STORMS ACROSS
THE NORTHLAND AS THAT TROUGH MOVES THROUGH THE NORTHLAND...AND THEN
NORTHWEST FLOW DEVELOPS AS A LOW EAST OF LAKE SUPERIOR HOVERS FOR A
COUPLE DAYS. THERE COULD BE MORE SHOWERS AND STORMS EARLY NEXT WEEK
WHEN A MID/UPPER LEVEL RIDGE BUILDS INTO THE CENTRAL US...BUT IT
WILL DEPEND ON HOW FAR EAST A SURFACE LOW MOVES INTO THE NORTHERN
PLAINS. TEMPERATURES THROUGH THE PERIOD SHOULD BE NEAR OR SLIGHTLY
ABOVE NORMAL.
