Area forecast discussion, Dec 10, 3:15 PM CST, 5 hours 7 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
315 PM CST MON DEC 10 2007
.DISCUSSION...SHORT TERM FORECAST FOCUSES ON WINTER WEATHER EVENT
EXPECTED TO DEVELOP LATE TONIGHT CONTINUING INTO TUESDAY WITH
SMALLER THREAT RETURNING LATER WEDNESDAY/WEDNESDAY NIGHT.
WATER VAPOR IMAGERY SHOWS DEEP MOISTURE SURGING NORTHWARD AHEAD OF A
CUTOFF UPPER LOW OVER THE BAJA AREA INTO THE SOUTHERN AND CENTRAL
PLAINS. PRECIPITABLE WATER VALUES OVER 200 PERCENT OF NORMAL IN THE
SOUTHERN PLAINS. UPPER LOW EXPECTED TO WEAKEN AND TRACK RAPIDLY
NORTHEAST INTO UPPER LEVEL CONFLUENT FLOW. INCREASING SOUTHERLY
WINDS WILL PULL DEEP MOISTURE QUICKLY NORTHWARD WITH RAPID INCREASE
OF PRECIP WATER VALUES OF ONE HALF INCH OVERNIGHT. PRECIPITATION
EFFICIENCY INCREASES TO NEAR 1.0 IN SOUTHERN WISCONSIN BY LATE TNGT.
IMPRESSIVE AREA OF 2-D FULL WIND FRONTOGENESIS DEVELOPS OVER
SOUTHERN WISCONSIN BY 18Z/TUE TIED TO WEAK SYNOPTIC SCALE FORCING
ASSOCIATED WITH RIGHT ENTRANCE REGION OF 300MB JET. STRONGEST LOW
LEVEL CONVERGENCE ACROSS TIGHT BAROCLINIC ZONE GRAZES SOUTHERN
WISCONSIN 09Z-15Z AND THEN QUICKLY SHIFTS OFF TO THE EAST. 295
THETA SURFACE HAS PUSH OF 30 KNOTS OF UPGLIDE AFTER 09Z AS
CONDENSATION PRESSURE DEFICITS DECREASE TO LESS THAN 10MB. MIXING
RATIOS INCREASE TO AROUND 4-5 G/KG. PRECIPITATION TYPE IS THE MAIN
QUESTION. SHORT TERM GUIDANCE CRITICAL THICKNESSES CONTINUE TO
FAVOR MIX ACROSS MOST OF SOUTHERN WISCONSIN FOR THE DURATION OF THE
EVENT...CHANGING OVER TO ALL SNOW IN THE AFTERNOON AND EVENING OR
ENDING. SURFACE COLD AIR EXTENDS WELL SOUTH INTO THE SOUTHERN PLAINS
WHERE TEMPS BLO FREEZING IN OK WHICH IS WELL SOUTH OF 1300 THICKNESS
LINE FOR 1000-850 LAYER. 1300 THICKNESS REMAINS SOUTH OF WISCONSIN
THROUGH EVENT WITH WARMER MID LAYERS. BEST OMEGA REMAINS IN LOWER
LEVELS...BELOW SNOW GROWTH AREA SO ATMOSPHERE WILL NOT BE AS
CONDUCIVE TO GOOD CRYSTAL DEVELOPMENT. FORECAST SOUNDINGS HOWEVER
IN NORTHWEST PORTION OF CWA FAVOR SNOW AND SLEET WITH ABOUT A 70
PERCENT CHANCE OF ICE FALLING INTO THE CLOUD LAYER. FARTHER
SOUTHEAST...APPEARS BETTER CHANCE FOR SLEET AND FREEZING RAIN
CUTTING BACK ON SNOW AMOUNTS. WITH CRITICAL THICKNESSES AND 2-D
FWF...CAN NOT RULE OUT HEAVIER THAN EXPECTED SNOWFALL AMOUNTS WITH
POTENTIAL FOR GLAZING IN EXCESS OF ONE QUARTER INCH IN SOUTHEAST.
HENCE ALREADY ISSUED WINTER STORM WATCH FOR AREAS OF SOUTHEAST WHERE
SIGNIFICANT ICING COULD BE A PROBLEM...WITH BUFFER ZONE TO THE
NORTHWEST FOR MIX OF ACCUMULATING SNOW...SLEET AND LIGHTER GLAZE.
EVENING SHIFT MAY WANT TO JUMP ON UPGRADING TO WARNING OR ADVISORY
IN WATCH AREA AS NEW DATA BECOMES AVAILABLE.
SHORT RANGE ENSEMBLE POPS NOW SHOWING GREATER THAN 75 PERCENT CHANCE
FOR OVER ONE QUARTER INCH OF PRECIPITATION OCCURRING TUE MRNG IN SRN
PTN OF COUNTY WARNING AREA.
APPEARS SYSTEM WILL REMAIN WELL SOUTH OF AREA FOR WEDNESDAY NIGHT
INTO EARLY THURSDAY...SO DROPPED POPS TO SCHC WORDING.
FOR THE EXTENDED PERIOD FROM THURSDAY NIGHT THROUGH MONDAY.
EXTENDED GUIDANCE INCLUDING CANADIAN...GFS AND ECMWF IN REASONABLE
AGREEMENT ON MID LEVEL TROUGH ROTATING THROUGH WESTERN GTLAKES EARLY
IN PERIOD...HOWEVER AMPLITUDE OF TROF IN QUESTION. GFS HAS BEEN
CONSISTENT IN SHARPENING TROF BLASTING THRU THU NGT/EARLY FRI WHILE
CANADIAN AND ECMWF NOT SHOWING AS MUCH AMPLITUDE. AMOUNT OF
MOISTURE APPEARS MEAGER AND ENSEMBLE PERCENT OF MEASUREABLE
PRECIPITATION REMAINS NEAR ZERO. HENCE WILL CONTINUE WITH DRY
FORECAST WORDING EARLY IN PERIOD FOR NOW BUT WOULD NOT BE SURPRISED
AT A FEW FLURRIES OCCURRING.
GFS ENSEMBLE MEMBERS IN FAIR AGREEMENT THROUGH SATURDAY BUT THEN
RAPIDLY DIVERGE AND BECOME UNRELIABLE BY SUNDAY AS GFS AMPLIFIES
TROFFING ACROSS NORTH CENTRAL CONUS WHILE ECMWF SHOWS MORE
BROADSCALE TROFFING. CONFIDENCE REMAINS LOW FOR LATE WEEKEND
OUTLOOK INTO MONDAY BUT WITH WEAK TROFFING IN AREA AND INCREASING
SLY WINDS...WOULD EXPECT THREAT FOR AT LEAST LIGHT PRECIP TO
INCREASE. GFS 500MB 5 DAY MEANS SHOWING MORE ZONAL FLOW AND NEAR
NORMAL HEIGHTS SETTING UP OVER NORTH CENTRAL CONUS NEXT WEEK. THIS
SHOULD ALLOW TEMPERATURES TO CLOSE IN ON MORE NORMAL LEVELS.
