AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
321 PM CST SUN DEC 30 2012
.SHORT TERM...SPLIT FLOW OVER CONUS WITH WELL DEFINED CYCLONICALLY
CURVED NRN BRANCH FROM ERN MT INTO CTRL MN. SRN BRANCH REMAINS
WELL SOUTH OF CWA FROM SWRN CONUS TO SRN IA. SFC LOW OVER WRN ONT
WITH A TRAILING COLD FRONT EXTENDING SOUTHWEST FROM LOW INTO NWRN
CORNER OF MN AND WEST ACROSS NODAK. TEMPS BEHIND THE FRONT DROP TO
BELOW ZERO ACROSS SASK/MANITOBA. AN AREA OF SNOW...MODERATE
INTENSITY AT TIMES...IS OCCURRING NEAR THE SFC FRONTAL SYSTEM OVER
NWRN CWA. SLOPING FRONTOGENESIS IN THE LOW TO MID LAYERS COMBINED
WITH OMEGA/DGZ IS MAINTAINING ORGANIZATION TO THE PRECIP.
TONIGHT...ARCTIC FRONT WILL SLIDE ACROSS REGION OVERNIGHT. GUSTY NW
WINDS AND SNOW FLURRIES SHOULD ACCOMPANY THE FROPA IN MOST LOCATIONS
EXCEPT PERHAPS THE SWRN CWA. MOST LIKELY AREA FOR ANY ADDITIONAL
ACCUMULATION WOULD TEND TO BE NEAR NRN MN ZONES WHERE BETTER DEEP
LAYER RH IS AVAILABLE. HAVE ISSUED A WIND CHILL ADVISORY FROM 6Z-15Z
FOR A LARGE PART OF THE MN CWA. ALTHOUGH WE MAY NOT SEE THE CRITERIA
UNTIL 9Z IN SOME LOCATIONS...WINDS MAY BE STRONGER THAN CURRENTLY
FCST. FCST 925MB TEMPS OF -16C TO -24C BY MORNING SUPPORT LOWS BELOW
ZERO IN THE ADVISORY AREA. SFC PRESS GRADIENT BEHIND FRONT IS
SIGNIFICANT ENOUGH TO KEEP WINDS BRISK THROUGH THE NIGHT. FCST
ISALLOBARIC RISE OF 4MB/3HR ACROSS ARROWHEAD MAY KEEP WINDS STRONG
WELL INTO THE MORNING.
TOMORROW/TOMORROW NIGHT...LOW LVL THERMAL TROUGH WILL RESIDE OVER CWA
MONDAY SO EXPECT A COLD DAY WITH MAX TEMPS WELL BELOW NORMAL IN
MOST AREAS. LES POTENTIAL APPEARS TO BE LIMITED BY SIGNIFICANT
DRYING IN SYNOPTIC SCALE AND LESS THAN FAVORABLE TRAJECTORY ACROSS
LAKE SFC. THIS WOULD TEND TO KEEP MAJORITY OF ACTIVITY EAST OF
CWA. A WEAK SHORTWAVE TROF IS SUGGESTED BY SOME NWP TO CROSS NRN
CWA LATE DAY/EVENING. CLOUDS MAY INCREASE BUT WILL KEEP ANY POPS
OUT OF FCST FOR NOW. MAY NEED TO LOWER MIN TEMPS FOR TUESDAY
MORNING AS LATEST SREF PLUMES FOR SEVERAL SITES SHOW MIN TEMPS
OVER -20F OVER NRN MN CWA.
LONG RANGE....TUESDAY THROUGH SUNDAY.
MAIN FOCUS IN LONG RANGE IS ON POPS WED/WED NIGHT. LONG RANGE
MODELS CONTINUES TO SHOW A STRENGTHENING SHORT WAVE DROPPING QUICKLY
SE OVER THE CANADIAN ROCKIES/SW MANITOBA TUESDAY NIGHT. THE LATEST
ECM SUGGESTS THE WAVE BRIEFLY BECOMES A CLOSED MID LEVEL LOW OVER
NORTHERN MN WEDNESDAY AS IT TRANSLATES ACROSS THE NORTHLAND AND
EXITS OVER THE GREAT LAKES/SRN ONTARIO THURSDAY. HAVE INCREASED TO
BROADBRUSH CHC POPS OVER THE DLH CWA WEDNESDAY...WITH SMALL POPS
LINGERING WEDNESDAY NIGHT...BUT SUSPECT THESE MAY NEED TO BE
INCREASED AS WELL AS TREND IS FOR A SLOWER TIMING. AT THIS TIME SNOW
AMOUNTS ARE EXPECTED TO BE LIGHT...ON THE ORDER OF AN INCH OR TWO.
THERE WILL BE A PERIOD OF LAKE AND TERRAIN ENHANCEMENT ALONG THE
SHORES OF LAKE SUPERIOR. LATEST NAM/GFS/ECM ARE IN AGREEMENT THAT BL
WINDS TURN OUT OF THE E/SE AS THE WAVE APPROACHES
WEDNESDAY...RESULTING IN A FAVORABLE TRAJECTORY FOR THE NORTH SHORE
ZONES. THEN WINDS TURN N/NW FAVORING THE SOUTH SHORE ZONES AS THE
LOW DEPARTS WED NIGHT/THURS. HOWEVER...THE FAVORED REGION FOR ANY
LAKE EFFECT SNOW WILL BE DEPENDENT ON TIMING AND TRACK OF THE SFC
LOW WHICH MODELS HAVE NOT SHOWN GOOD CONSISTENCY WITH AND CONFIDENCE
IN CURRENT TRACK IS LOW.
.AVIATION.../18Z TAF ISSUANCE/
THE REGION WILL BE SITUATED IN A SOUTHERLY FLOW AHEAD OF A COLD
FRONT TODAY. VFR CONDITIONS WILL PREVAIL THROUGH 00Z. THE
EXCEPTION WILL BE AT KINL WHERE MVFR CIGS AND LIGHT SNOW WILL BE
FOUND. THE COLD FRONT WILL SWEEP SOUTHEAST ACROSS THE REGION
OVERNIGHT...BRINGING INCREASING CLOUDS AND WINDS SHIFTING OUT OF
THE NORTHWEST. EXPECT GUSTS AROUND 20 KT TOP BE FOUND ALONG AND
JUST BEHIND THE FRONTAL PASSAGE TONIGHT. THE STRONGEST GUSTS WILL
BE IN THE KINL AREA. SKIES WILL CLEAR FROM THE NORTHWEST THROUGH
MONDAY MORNING WITH BUILDING HIGH PRESSURE.
