AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
349 AM CDT SUN MAR 10 2013

.TODAY AND TONIGHT...FORECAST CONFIDENCE IS MEDIUM TO HIGH.

EXPECT ONGOING RAIN TO DIMINISH FOR A TIME THIS MRNG AS ENHANCED
SYNOPTIC SCALE FORCING ASSOCIATED WITH RIGHT ENTRANCE REGION OF
UPPER JET PUSHES OFF TO THE NORTHEAST. EXPECT UPSTREAM SURFACE
TROUGH OVER WESTERN WISCONSIN TO CONTINUE SLIDING EAST AND FURTHER
WEAKENING THIS MRNG. LIGHTENING BOUNDARY LAYER WINDS AND VERY
MOIST LOW LEVELS WILL RESULT IN PATCHY TO AREAS OF DENSE FOG.

GOOD BET FOR MORE WIDESPREAD DENSE FOG IN SUSCEPTIBLE WESTERN
AREAS THIS MRNG AS LIGHT RAIN DIMINISHES FOR A TIME. A NUMBER OF
UPSTREAM OBSERVATIONS ALREADY REPORTING DENSE FOG IN CENTRAL WI
INTO NORTHEAST IA. HENCE WL POST DENSE FOG ADVY FOR FAR WEST AND
NORTHWEST THIS MRNG UNTIL WINDS SHIFT TO THE NORTH AND INCREASE
LATE THIS MRNG. LIKELY TO BE DENSE FOG FARTHER EAST THIS MRNG BUT
WILL BE MORE PATCHY DUE TO MORNING RAINFALL. MIGHT BE ENOUGH TIME
TO WARRANT DENSE FOG ADVY IN CENTRAL SECTIONS THIS MRNG. WL WATCH
OBS CLOSELY.

LULL IN RAINFALL WILL BE SHORT-LIVED AS STRONG Q-VECTOR
CONVERGENCE ASSOCIATED WITH LOW PRESSURE STRENGTHENING ALONG
BAROCLINIC BOUNDARY TO THE SOUTH WILL SPREAD BACK INTO SOUTHERN WI
THIS AFTERNOON. LEANING TOWARD MORE CONSISTENT GFS SOLUTION WITH
THE TRACK AND TIMING OF THIS NEXT WEATHER SYSTEM. ECMWF NOW
SHOWING BACK TO BACK MODEL RUNS SIMILAR TO GFS SOLUTION AS WELL.
UPPER LEVEL COUPLED JET DEVELOPS THIS AFTERNOON AND EVENING AND
RESULTS IN CYCLOGENESIS OF LOW PRESSURE ALONG BAROCLINIC ZONE TO
THE SOUTH OF WI. STRONG MID-LEVEL SHORT WAVE PASSES ACROSS
SOUTHERN WI DURING THIS TIME RESULTING IN WIDESPREAD RAINFALL
RETURNING.

700H LOW PRESSURE PASSES ACROSS WESTERN CWA TONIGHT...RESULTING IN
LINGERING PERIOD OF DEFORMATION FORCING ACROSS THE FAR NORTHWEST.
DURING THE EVENING...COLDER AIR WRAPS INTO THE LOW PRESSURE
CIRCULATION CHANGING THE RAIN OVER TO SNOW OVER THE FAR WEST.
SLOPING FRONTOGENETICAL FORCING IN THE DENDRITE ZONE WL RESULT IN
A 4-6 HOUR PERIOD OF MODERATE TO HEAVY SNOW IN THE FAR NORTHWEST.

EXPECT LOW SNOW LIQUID RATIOS AVERAGING 10 TO 1 DURING THIS
PERIOD. HENCE LOOKING FOR SNOW AMOUNTS AROUND 6 INCHES IN WESTERN
PARTS OF SAUK AND MARQUETTE COUNTIES...WITH LOWER AMOUNTS JUST TO
THE EAST AND SOUTH. WL UPGRADE WINTER STORM WATCH TO WARNING FOR
THESE COUNTIES...WITH AN ADVISORY JUST TO THE EAST AND SOUTH...NOT
INCLUDING DANE COUNTY.

FARTHER EAST...MID-LEVEL DRY SLOT ROTATING AROUND LOW CIRCULATION
SURGES INTO EASTERN CWA DURING THE OVERNIGHT AS COLDER AIR ONLY
SLOWLY SLIDES EAST. HENCE LIGHTER PRECIPITATION EXPECTED IN THE
CENTRAL AND EAST AFTER MAIN RAIN AREA DIMINISHES LATER IN THE
EVENING.

.MONDAY THROUGH TUESDAY NIGHT...FORECAST CONFIDENCE IS MEDIUM TO
HIGH.

SHORT TERM MODELS TAKE THE SURFACE LOW FROM CENTRAL LAKE MICHIGAN
TO NORTHERN LOWER MICHIGAN ON THE NAM/GFS MONDAY...THEN SLOWLY
NORTHEAST MONDAY NIGHT. CANADIAN MODEL IS SOMEWHAT SLOWER THAN THE
NAM/GFS/ECMWF WITH MOVING THE LOW OUT OF THE REGION. LIKE THE
QUICKER MOVEMENT OF THE NAM/GFS/ECMWF. 500MB SHORTWAVE TROUGH
SLIDES NORTHEAST THROUGH THE AREA MONDAY MORNING...THEN NORTHEAST
OF THE AREA MONDAY AFTERNOON. CANADIAN DOES LINGER THE SHORTWAVE
IN THE AREA DURING THE AFTERNOON...BUT IS LIKELY TOO SLOW.

MAIN ISSUE MONDAY WILL BE PRECIPITATION TYPE. AREA FORECAST
SOUNDINGS FROM THE NAM/GFS SHOW NO ICE CRYSTALS IN AIR COLUMN FOR
THE MORNING...BEFORE SOME DO FORM AT TIMES DURING THE AFTERNOON.
THIS LIKELY A RESULT OF DRY SLOT WORKING INTO THE AREA. USING TOP
DOWN METHOD...PERIOD OF FREEZING DRIZZLE WOULD BE POSSIBLE WITH
ANY LINGERING LIGHT SNOW DURING THE MORNING...UNTIL TEMPERATURES
WARMED ABOVE FREEZING. WOULD SEE MORE OF A LIGHT RAIN/SNOW MIX
DURING THE AFTERNOON...WITH TEMPERATURES AROUND OR SLIGHTLY ABOVE
FREEZING.

CONTINUED TREND OF HIGH POPS IN THE MORNING IN THE NORTHWEST
PORTIONS OF THE AREA...AS SHORTWAVE MOVES THROUGH AND REMNANTS OF
MID LEVEL FRONTOGENESIS RESPONSE MOVES OUT. LOWER POPS WERE KEPT
TO THE SOUTHEAST...WITH LOWER END POPS FOR THE AFTERNOON.

AIRMASS DRIES OUT MONDAY NIGHT...WITH COLD AIR ADVECTION MOVING
THROUGH THE AREA. TEMPERATURES WILL FALL SLIGHTLY BELOW NORMAL.
NAM/GFS THEN BRING IN AN AREA OF LIGHT QPF FOR TUESDAY...AS A
500MB VORTICITY MAXIMUM MOVES THROUGH THE REGION. CANADIAN IS DRY
TUESDAY...WITH THE ECMWF BRINGING IN QPF DURING THE AFTERNOON.
AREA FORECAST SOUNDINGS FROM NAM/GFS SHOW SATURATED LOW LEVELS
WITH STEEP LAPSE RATES AND EVEN SOME WEAK CAPE AS THE DAY GOES ON.

KEPT LOW POPS FOR TUESDAY...BUT MAY HAVE TO RAISE IN LATER
FORECASTS IF STEEP LAPSE RATES PERSIST WITH PASSING UPWARD MOTION.
CONTINUED THE TRANSITION FROM LIGHT SNOW SHOWERS IN THE
MORNING...TO A MIX OR ALL LIGHT RAIN SHOWERS IN THE AFTERNOON AS
TEMPERATURES WARM.

NAM KEEPS LIGHT QPF GOING THROUGH TUESDAY NIGHT...AS LOW LEVELS
REMAIN MOIST AND SOMEWHAT UNSTABLE WITH SHEARED VORTICITY AXIS
MOVING THROUGH. GFS DRIES AIR COLUMN OUT DURING THIS TIME...AND IS
DRY. ECMWF/CANADIAN MODELS ALSO DRY THINGS OUT LIKE THE GFS...SO
WILL SIDE WITH THEM AND KEEP DRY FORECAST. TEMPERATURES WILL BE
NEAR OR SLIGHTLY BELOW SEASONAL NORMALS.

.WEDNESDAY THROUGH SATURDAY...FORECAST CONFIDENCE IS MEDIUM.

ECMWF/GFS IN FAIR AGREEMENT WITH OVERALL TRENDS DURING THIS
PERIOD. THEY SHOW 500MB FLOW REMAINING NORTHWEST ACROSS THE
REGION. VORTICITY MAXIMUM EXITS THE REGION WEDNESDAY...AS SURFACE
HIGH PRESSURE MOVES INTO THE REGION. THE HIGH LINGERS ACROSS THE
REGION WEDNESDAY NIGHT AS WELL. AIRMASS IS FAIRLY DRY...SO WENT
WITH DRY FORECAST ACROSS MOST OF THE AREA. NEAR NORMAL
TEMPERATURES ARE EXPECTED.

MODELS THEN SHOW SOME DIFFERENCES THURSDAY INTO SATURDAY. THE GFS
BRINGS A POTENT 500MB VORTICITY MAXIMUM SOUTHEAST THROUGH THE AREA
LATER THURSDAY INTO THURSDAY EVENING...WITH THE ECMWF SHOWING A
WEAKER VORTICITY MAXIMUM. GFS BRINGS FOCUSED WARM AIR ADVECTION
AND A SATURATED AIRMASS THROUGH THE AREA...AND RESULTANT LIGHT TO
MODERATE QPF. THE ECMWF IS DRY DURING THIS TIME. KEPT LOW END POPS
FOR THURSDAY INTO THURSDAY NIGHT FOR NOW.

ECMWF IS QUICKER THAN GFS WITH NEXT SYSTEM FOR FRIDAY
NIGHT/SATURDAY. 500MB VORTICITY MAXIMA SLIDE SOUTHEAST THROUGH
MAINLY NORTHERN WISCONSIN. GFS FORECAST SOUNDINGS DO SHOW A FAIR
AMOUNT OF MOISTURE TO WORK WITH. FOR NOW...USED CONSENSUS POPS AND
TEMPERATURES FOR THIS PERIOD.

&&

.AVIATION/12Z TAFS/...

EXPECT CIGS/VSBYS TO LOWER THIS MRNG AS BOUNDARY LAYER WINDS
LIGHTEN AND LIGHT RAIN ENDS AS SFC TROUGH APPROACHES. LIKELY TO
LOWER TO LIFR FOR A PERIOD THIS MRNG...AND THEN INCREASE BACK TO
IFR OR EVEN MVFR THIS AFTN AS WINDS INCREASE. MORE RAIN AND
DRIZZLE TONIGHT WITH A MIXTURE CHANGING TO LIGHT SNOW IN KMSN.

&&

.MARINE...

WEAKENING PRESSURE GRADIENT HAS ALLOWED WINDS TO SUBSIDE
OVERNIGHT. WAVE HEIGHTS CONTINUE TO DIMINISH AS WELL AND SHOULD
DROP BELOW 4 FEET EARLY THIS MORNING. HENCE WL SHORTEN END TIME OF
ONGOING SMALL CRAFT ADVY TO EXPIRE AT 12Z THIS MRNG.

LOW PRESSURE REFORMING ALONG BOUNDARY TO THE SOUTH WILL MOVE
ACROSS SOUTHERN LAKE MICHIGAN TONIGHT. PRESSURE GRADIENT WILL
RAPIDLY TIGHTEN OVER SOUTHERN LAKE MICHIGAN LATE THIS AFTERNOON
AND EVENING. WINDS AND WAVES WILL LIKELY RETURN TO SMALL CRAFT
ADVISORY LEVELS FOR A TIME...ESPECIALLY NORTH OF WIND POINT.
DIMINISHING LOW LEVEL WINDS AS SURFACE TROUGH APPROACHES WILL
LIKELY RESULT IN PATCHY DENSE FOG LATER THIS MRNG INTO THE EARLY
AFTERNOON...BUT OCCASIONAL RAIN WILL CONTRIBUTE TO MINIMIZING
DURATION.
