327 PM CDT MON APR 25 2011

...BIG CHANGE IN WEATHER NEXT 24 HOURS...

...ACCUMULATING SNOW POTENTIAL FOR PARTS OF NORTHLAND...

.DISCUSSION...MSAS THIS AFTN INDICATES WEAK FRTL BDRY HAS SLIPPED
SOUTH INTO RANGE. WITH LARGE T/TD SPREADS IN LOW LVLS...CLOUD
BASES ARE RELATIVELY HIGH. WITH 85/70H LAPSE RATES BETWEEN 7C/KM
TO 8C/KM...MAY YET SEE SOME HIGHER BASED RW LATE THIS AFTN/EARLY
EVENING NEAR LL THETAE AXIS FROM NEAR TWIN PORTS WEST AND NORTH.

NRN BRANCH OF WESTERLIES IS RETREATING AS PATTERN SHIFT DEVELOPS
THE REMAINDER OF THE WEEK. COMPLEX UPPER FLOW AS INITIAL SHORTWAVE
TROF OVER SRN PLAINS IS EJECTED NNE TOWARDS IA. SECONDARY...FAST
MOVING... SHORTWAVE TROF WILL MOVE INTO WRN HIGH PLAINS BY TUES
EVE. ALL MDLS ARE DEVELOPING CLOSED MID LVL LOW OVER SERN MN/WRN
WISC TUES NIGHT AND LIFTING NORTH BY WED. AT THE SFC...SHOULD SEE
A SFC LOW MOVE FROM SRN PLAINS INTO WRN WIS BY TUES EVE...AND THEN
DRIFT SLOWLY TOWARDS NRN WISC EARLY WED. BY THAT TIME STRONG UPPER
JET CORE WILL STRENGTHEN OVER SRN PLAINS AND INDUCE CYCLOGENESIS
FROM LOWER MS VALLEY INTO ERN GT LAKES. THIS SHOULD BECOME THE
MAIN AREA OF MSTR TRANSPORT/LIFT WED NIGHT/THUR. MDLS ARE IN
CONSIDERABLY GOOD AGREEMENT WITH OVERALL SYNOPTIC SCALE PATTERN
AND INHERENT CHANGES.

AS FAR AS SENSIBLE WEATHER...THEREIN LIES THE QUANDARY. THE TREND
OVER THE PAST FEW DAYS HAS BEEN TO INCREASE THE LIKELIHOOD OF AN
AREA OF POTENTIALLY SIGNIFICANT SNOW ON THE NORTHWEST PERIPHERY OF
THE DEEP LAYER CIRCULATION. EC/GEM/GFS/NAM/SREF ALL MAINTAIN AN
AXIS OF MDT/HVY SNOW ACCUMULATIONS. HOWEVER DUE TO DIFFERENCES IN
THERMODYNAMICS THE LOCATION IS STILL EXHIBITING A FAIR AMOUNT OF
VARIANCE. LATEST HPC WWD GUIDANCE HAS RETREATED SIGNIFICANTLY FROM
EARLIER MDT/HVY TOTALS ACROSS NCTRL WISC ZONES. WILL NOT HOIST ANY
WSW GIVEN LACK OF CONFIDENCE IN BOTH AREA AND AMOUNTS. SPRING
SYSTEMS ARE QUITE COMPLICATED BY CRITICAL NATURE OF BDRY LYR TEMP
AND ANTECEDENT SFC CONDITIONS. WE DO KNOW THAT TEMPS WILL PLUMMET
ALONG LAKEFRONT WITH STRONG WIND OFF COLD LAKE. RAIN WILL SPREAD
NORTH SLOWLY TUESDAY...POSSIBLY MIXING WITH SNOW AS EARLY AS LATE
AFTN ACROSS NORTHWEST WISC/TWIN PORTS/NSHORE. TOMORROW NIGHT WITH
THICKNESS COLLAPSING UNDER APPROACHING UPPER LOW....DENDRITES
WILL BE FALLING BUT NEAR SFC LAYER WILL NEED TO DROP A FEW DEGREES
TO MAINTAIN SNOW AS PRIMARY PTYPE. AT THIS TIME...USING MDL SNDGS
AND HPC SUPER ENSEMBLE SNOW ACC PROBABILITIES...A CORRIDOR FROM
THE BAYFIELD PENINSULA INTO ERN ARROWHEAD MAY BE IN THE LOCATIONS
OF HIGHER SNOW TOTALS. BUT...EMPHASIZING THAT MORE SIGNIFICANT
TOTALS ARE POSSIBLE GIVEN THE ANOMALOUS NATURE OF THE SYSTEM AND
ITS SLOW MOVEMENT. A SLOW MOVING DEFORMATION ZONE WILL KEEP THE
AREA UNDER CLOUDS AND PRECIP INTO THURSDAY BEFORE DEEP LAYER
DRYING ADVECTS INTO THE CWA  THUR NIGHT.

THU NITE THRU MON...
THU NITE/FRI SHUD BE DRY WITH TEMPORARY RIDGING BTWN SYSTEMS. FRI
NITE THRU MON LOOKS WET AS A LARGE VERT STACKED SLOW MOVING LOW
PRESS SYSTEM MAKES ITS WAY EWD ACRS SRN CN. TEMPS COULD DROP ENUF
FOR A RA/SN MIX SAT NITE AND SUN NITE AS NWLY WINDS BRING IN LWR
THKNS VALUES ALONG WITH LOWER SFC TEMPS.

.AVIATION...UPDATE FOR 18Z TAFS
