Hail and Lightning Strikes in Wisconsin, March 6, 2016

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
320 PM CST SUN MAR 6 2016

.TONIGHT AND MONDAY...FORECAST CONFIDENCE - MEDIUM.

MAY STILL SEE A FEW SHOWERS THIS EVENING AS MOISTURE/TEMPS CONTINUE
TO INCREASE ACROSS THE AREA. LOOKS LIKE MAINLY ISOLATED COVERAGE
...SO KEPT POPS LOW.

WITH LOW LEVEL JET OVERHEAD TONIGHT...WINDS WILL NOT GET VERY LIGHT.
ADDITIONALLY...EXPECTING A FAIR AMOUNT OF CLOUDS. THESE FACTORS
ALONG WITH CONTINUED WARMING ALOFT WILL RESULT IN MILD LOW TEMPS
TONIGHT. WENT A TOUCH ABOVE A CONSENSUS MODEL BLEND.

A BIG SURGE OF LOWER LEVEL MOISTURE WILL RESULT IN INCREASING CLOUDS
AND A CHANCE FOR SHOWERS MONDAY...MAINLY LATE MORNING INTO THE
AFTERNOON. SHOULD BE A PRETTY MILD DAY TOMORROW...WITH HIGHS IN THE
MID TO UPPER 50S MOST PLACES. IT WILL BE COOLER ALONG THE LAKE
MICHIGAN SHORE...PARTICULARLY IN PLACES THAT ARE MORE EXPOSED TO THE
LAKE AIRMASS UNDER A SOUTHERLY FLOW. WINDS WILL HAVE A BIT OF AN
EASTERLY COMPONENT NORTH OF MILWAUKEE...SO COOLEST TEMPS EXPECTED
THERE ALONG THE SHORE.

.MONDAY NIGHT THROUGH WEDNESDAY...FORECAST CONFIDENCE - MEDIUM
TRENDING LOW.

PERSISTENT SOUTH WINDS WILL CONTINUE TO USHER MILD...MORE HUMID AIR
INTO SRN WI FOR BULK OF THIS PERIOD. COLUMN PWAT IN THE PROCESS OF
INCREASING TO AROUND THREE QUARTERS INCH BY THIS EVENING...WITH
ANOTHER SURGE OF DEEPER MOISTURE ELEVATING PWAT TO OVER AN INCH BY
MON EVE.  WATER VAPOR IMAGERY SHOWS PLENTY OF MID LEVEL MOISTURE
SPREADING INTO THE UPPER MIDWEST FROM THE SOUTHWEST AHEAD OF
VIGOROUS SHORT WAVE OVER CENTRAL CA. THIS WAVE ALONG WITH A SECOND
EVEN STRONGER UPSTREAM WAVE OVER THE EASTERN PACIFIC WILL RESULT IN
AMPLIFYING TROFFING OVER WESTERN CONUS NEXT 24 HOURS.  THE END
RESULT WILL BE STRONGER SOUTHERLY STEERING CURRENTS INTO THE WESTERN
GTLAKES.  SEVERAL PERIODS OF SHRA POSSIBLE THROUGH THIS PERIOD AS
PIECES OF SHORT WAVE ENERGY GET EJECTED NORTHEAST FROM UPSTREAM
DIGGERING TROF.  STRENGTHENING LOW LEVEL JET OVER STATES TO THE WEST
MONDAY NIGHT WILL PIVOT NORTHEAST AND WEAKEN INTO TUESDAY MORNING.
THIS WILL BRING A HIGHER CHANCE FOR SHRA ACROSS THE AREA DURING THIS
PERIOD.  LITTLE ELEVATED INSTABILITY WITH STRONG CAPPING INVERSION
SO WL REMOVE THUNDER THREAT.

LOW LEVEL JET REDEVELOPS TUESDAY NIGHT AS SLOW MOVING...WEAKENING
COLD FRONT MOVES INTO SRN WI.  CONSISTENT ECMWF CARRIES WEAK FRONT
OUT OF SOUTHEAST WI ON AS DOES GEM-NH WHILE GFS AND NOW 18Z NAM
WEAKEN FRONT RIGHT OVER CENTRAL/ERN WI.  SLIGHTLY BETTER ELEVATED
INSTABILITY TUESDAY NIGHT SO WL CONTINUE SMALL CHANCE FOR THUNDER
AND CARRY SLIGHTLY HIGHER POPS ACROSS AREA INTO WED DUE TO LINGERING
BOUNDARY.

.EXTENDED PERIOD...

WEDNESDAY NIGHT THROUGH SUNDAY...FORECAST CONFIDENCE - LOW.

SIGNIFICANT DIFFERENCES SHOW UP IMMEDIATELY BETWEEN ECMWF AND GFS
SOLUTIONS.  MORE CONSISTENT ECMWF SHOWING STRONGER SPLIT FLOW ACROSS
MIDWEST.  MORE PROGRESSIVE ZONAL TO SW STEERING FLOW WOULD CARRY
STRONG SFC FRONT EWD ACROSS WESTERN GTLAKES WED NGT AND EARLY THU.
GEM-NH INITIALLY MORE PROGRESSIVE AS WELL WHILE LATEST DETERMINISTIC
GFS SHOWING MUCH SLOWER EWD PROGRESSION AND MORE SOUTHWEST UPPER
LEVEL STEERING FLOW.  GFS AND GEM ALSO CARRY LOW PRESSURE ALONG
FRONT TO THE SOUTHEAST OF WI...WHICH WOULD RESULT IN MORE RAIN
ACROSS SE WI WED NGT INTO THU MRNG.  THINKING GFS MAY BE PREMATURE
IN BRINGING CUTOFF LOW NWD OUT OF OLD MEXICO ON WED SO LEANING
TOWARD DRIER...MORE PROGRESSIVE ECMWF.  LATEST DGEX ALSO IN THIS
DRIER CAMP FOR WED NGT AND THU.  WPC FAVORING A BLEND OF ECMWF AND
GEFS BLEND.  DUE TO UNCERTAINTY...WL CONTINUE TO CARRY CHANCE POPS
FOR -SHRA ACROSS SRN WI INTO THU.

CUTOFF UPPER LOW OVER OLD MEXICO WL EVENTUALLY GET NUDGED NEWD DUE
TO PIECE OF SHORT WAVE ENERGY PUSHING ASHORE IN CA FRI NGT.  WHILE
ZONAL FLOW WEAKENS ACROSS THE MIDWEST ON SATURDAY...SHORT WAVE
RIDGING AHEAD OF SRN PLAINS LOW WL RESULT IN DRY AND MILD CONDITIONS
FOR THE START OF THE WEEKEND.  SORRY LAKESHORE AREAS BUT MILD WILL
NOT APPLY DUE TO ONSHORE FLOW KEEPING DAYTIME TEMPS MOSTLY IN THE
40S.  GFS AND ECMWF ALSO DIVERGE ON TRACK AND STRENGTH OF NORTHEAST
DRIFTING LOW OVER THE WEEKEND. GFS FASTER AND FARTHER TO THE
SOUTHEAST WILE EMWCF USHERS GRADUALLY DEEPER MOISTURE BACK INTO THE
REGION ALONG WITH A CHANCE FOR -SHRA ON SUNDAY.  ALL IN ALL
CONFIDENCE LOW ON SHOWER THREAT AND WL LIKELY HAVE WISHY-WASHY LOWER
POPS FOR MUCH OF THE EXTENDED PERIOD.  BETTER CONFIDENCE IN
TEMPERATURES HOLDING NEAR OR SLIGHTLY ABOVE NORMAL FOR THIS PERIOD
WITH THE COOLEST DAYTIME TEMPS BY LAKE MI DUE TO EXPECTED ONSHORE
FOR MUCH OF THE PERIOD.

.AVIATION/00Z TAFS/...

VFR CONDITIONS ARE EXPECTED INTO TONIGHT. MAY SEE A FEW SHOWERS
DEVELOP IN THE WEST BY LATE THIS AFTERNOON...WITH SMALL CHANCES
LINGERING ACROSS THE FORECAST AREA INTO TONIGHT.

EXPECTING A BIGGER PUSH OF LOW LEVEL MOISTURE MONDAY...WHICH WILL
RESULT IN SOMEWHAT HIGHER RAIN CHANCES. ALSO...HIGHER DEWPOINTS
ADVECTING ACROSS LINGERING SNOW COVER AND A COLD GROUND WILL MAY
RESULT IN SOME REDUCED VISIBILITIES. AT THE VERY LEAST...IT LOOKS
LIKE CIGS WILL GO BACK DOWN TO AT LEAST MVFR TOMORROW.

CURRENT WIND SHEAR IN TAFS SEEMS REASONABLE PER LATEST GUIDANCE.

.MARINE...

TIMING OF SMALL CRAFT ADVISORY THROUGH LATER TONIGHT STILL LOOKS
GOOD AS GUSTY SOUTH WINDS CONTINUE.

WINDS WILL BE A BIT LIGHTER MONDAY...WITH SMALL CRAFT CONDITIONS
POSSIBLE AGAIN TUESDAY.

RESULT IN FOG AT TIMES THE NEXT COUPLE DAYS.
