FORECAST DISCUSSION FOR ROUTINE MORNING FORECAST ISSUANCE

.SHORT TERM...TODAY...TONIGHT...AND THURSDAY
ISSUED AT 433 AM CDT WED APR 10 2013

BUSY NIGHT...WILL LET CURRENT ADVISORY RUN THROUGH EARLY MORNING
HOURS...WITH MIX CONTINUING. DRY AIR FLOWING IN OFF HIGH DROPPED
DEW POINTS INTO THE TEENS AND LOWER 20S...MUCH LOWER THAN EARLIER
FORECAST. THAT ALONG WITH LOSS OF LOW CLOUDS ALLOWED TEMPS TO DROP
TO FREEZING OR BELOW...ESPECIALLY ONCE PCPN STARTED. MIX OF
RAIN...FREEZING RAIN...SLEET AND SNOW FELL OVERNIGHT...WITH WAUSAU
PICKING UP AT LEAST AN INCH OF SNOW THROUGH 230AM. LAST BAND OF PCPN
WITH THIS WAVE NOW MOVING OUT OF CENTRAL WI...WITH MOSTLY SNOW
SEEN IN OBS AT WESTERN SITES. DRY AIR KEPT PCPN SOUTH OF AN IMT
TO TKV LINE.

MAIN CHANGES THIS PERIOD WAS TO BRING TIMING INTO FCST...WITH LULL
IN PCPN FOR LATE MORNING AND EARLY AFTN TODAY AND TO CUT BACK ON
POPS/QPF FAR NORTH...AS MODELS AGAIN INDICATE LACK OF SATURATION
THROUGH TONIGHT. WILL BRING BACK THUNDER IN THE SOUTH GIVEN STEEP
LAPSE RATES WITH NEXT WAVE THIS EVENING. SOUNDINGS INDICATE ANOTHER
MESSY NIGHT WITH FREEZING RAIN/SLEET MAIN PCPN FORM OVER CENTRAL
AND EAST CENTRAL WI LATE THIS EVENING INTO THU MORNING. WARRANTS
ANOTHER HEADLINE...THOUGH WITH CURRENT ONE IN EFFECT WILL NOT
ISSUE WITH THIS PACKAGE.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY
ISSUED AT 433 AM CDT WED APR 10 2013

A PERSISTENT UPR RDG OVER THE ERN PACIFIC WL CONT TO
PRODUCE DOWNSTREAM UPR TROFFING OVER THE WRN/CNTRL CONUS AND ALLOW
SYSTEMS TO DIVE SE THRU THE ROCKIES BEFORE EJECTING E-NE TOWARD
THE GREAT LAKES. THE FIRST OF THESE SYSTEMS TO CONT IMPACTING NE
WI WEATHER THRU FRI WITH THE SECOND SYSTEM SET TO ARRIVE SUNDAY
INTO MON AND THE THIRD SYSTEM TOWARD THE MIDDLE OF NEXT WEEK.
OBVIOUSLY...ABOVE NORMAL PCPN IS EXPECTED WITH TEMPS REMAINING
BELOW NORMAL.

LAST OF THE SFC WAVES TO MOVE ALONG THE QUASI-STATIONARY FNT
DRAPED ACROSS SRN WI THU NGT. IN ADDITION...THE CLOSED UPR LOW
FINALLY REACHES THE WRN GREAT LAKES AND WL HELP TO COOL THE
ATMOSPHERIC COLUMN ALOFT. ANY LINGERING MIXED PCPN OVER E-CNTRL WI
EARLY THU EVENING SHOULD COMPLETELY CHANGEOVER TO ALL SNOW WITH
THE ENTIRE FCST AREA SEEING LIGHT TO OCCASIONALLY MODERATE SNOW
OVRNGT. NRN WI STILL LOOKS TO RECEIVE THE HIGHER SNOW AMOUNTS DUE
TO A HIGHER SNOW-TO-WATER RATIO. LOOK FOR ADDITIONAL ACCUMULATIONS
TO RANGE FROM AROUND AN INCH OVER E-CNTRL WI...TO 2 TO 4 INCHES
NEAR THE MICHIGAN BORDER.

THE UPR LOW MOVES NEWD TOWARD THE NE SECTION OF THE GREAT LAKES ON
FRI LEAVING A COLD/CYCLONIC FLOW OVER WI. EXPECT TO SEE SNOW SHWRS
PREVAIL ACROSS THE FCST AREA THRU MUCH OF THE DAY WITH MOST
ACCUMULATION NUMBERS REMAINING AT LESS THAN AN INCH. COLDER AIR
GETTING WRAPPED AROUND THE UPR LOW WL SEND 8H TEMPS DOWN TO NEAR
-10C OVER NE WI...THUS DO NOT LOOK FOR TEMPS TO MOVE TOO MUCH ON
FRI. MAX TEMPS IN THE MID TO UPR 30S APPEARS THE BEST WE WL BE
ABLE TO DO WHICH WOULD ALMOST BE 20 DEGS BELOW NORMAL.

WEAKENING CYCLONIC FLOW TO LINGER OVER THE WRN GREAT LAKES INTO
FRI NGT...BUT AS THE SYSTEM CONTS TO PULL FARTHER AWAY...EXPECT
ANY SNOW SHWR ACTIVITY TO BECOME MORE ISOLATED WITH TIME. BEST
POTENTIAL TO SEE SNOW SHWRS MAY BE N-CNTRL WI DUE TO PREVAILING
N-NW WINDS AND COLD AIR MOVING OVE LAKE SUPERIOR. OTHERWISE...
PLENTY OF CLOUDS TO REMAIN THRU THE NGT WITH TEMPS LOOKING MORE
FEBRUARY-LIKE THAN APRIL WITH READINGS IN THE TEENS TO LWR 20S.
OTHER THAN THE GFS WHICH REMAINS MORE PESSIMISTIC WITH THE CLOUDS
(ALONG WITH SOME SNOW SHWRS)...THE REST OF THE MDLS SHOW A WEAK
RDG OF HI PRES PUSHING INTO THE REGION FOR SAT. HAVE FOLLOWED THE
MAJORITY HERE AND WL TRY TO BRING AT LEAST SOME MIXED SUNSHINE TO
NE WI ALTHO TEMPS WL NOT RESPOND AND REMAIN WELL BELOW NORMAL.
LOOK FOR MAX TEMPS TO ONLY REACH THE UPR 30S TO LWR 40S.

AFTER A QUIET SAT NGT...ATTENTION TURNS TO THE NRN PLAINS WHERE
THE SECOND SYSTEM TO ALREADY BE SITUATED. SOUTHERLY WINDS IN
ADVANCE OF THIS SYSTEM WL REACH WI ON SUNDAY WITH INCREASING ISEN
LIFT HELPING TO GENERATE THE NEXT ROUND OF PCPN INTO THE FCST AREA.
NOT SURE WHAT THE GFS IS TRYING TO DO BY WEAKENING THE ACCOMPANYING
SFC LOW OVER THE NRN PLAINS...THUS HAVE DISCOUNTED THIS MDL FOR
SUNDAY. DEPENDING ON EXACTLY WHEN THE PCPN BEGINS...THE AIR MASS
MAY STILL BE COLD ENUF TO START AS A RAIN/SNOW MIX BEFORE CHANGING
MORE TO RAIN BY SUNDAY AFTERNOON. WINDS TURNING TO THE SOUTH ALOFT
SHOULD BE ABLE TO ADD A FEW DEGS TO THE TEMPS WITH MOST LOCATIONS
REACHING THE LWR TO MID 40S.

THIS NEXT SYSTEM IS PROGGED TO MOVE FROM NRN MN INTO EXTREME SRN
ONTARIO DURING THE SUNDAY NGT/MON TIME FRAME. THE ASSOCIATED CDFNT
WL SWEEP ACROSS WI LATE SUNDAY NGT OR EARLY MON MORNING AND BRING
ENUF LIFT TO THE AREA TO KEEP AT LEAST A CHC OF EITHER A RAIN/SNOW
MIX OR RAIN IN THE FCST THRU MON. AS THIS SYSTEM PASSES TO OUR
NORTH...IT WL DRAW MILDER AIR INTO WI WITH MAX TEMPS ON MON RANGING
FROM THE LWR 40S NORTH TO NEAR 50 DEGS OVER E-CNTRL WI.

EVEN AS SYSTEM NUMBER 2 BEGINS TO PULL AWAY MON NGT...SYSTEM NUMBER
3 TO ALREADY BE IN THE PROCESS OF MOVING THRU THE CNTRL/SRN ROCKIES
IN THIS BUSY/ACTIVE WEATHER PATTERN. PIECES OF SHORTWAVE ENERGY ARE
FCST TO EJECT NEWD FROM THE MAIN UPR TROF AND BRING THE NEXT CHC OF
PCPN TO NE WI BY TUE. ONCE AGAIN...PCPN TYPE WL BE DETERMINED BY
WHEN THE PCPN ACTUALLY BEGINS. SINCE WE ARE THIS FAR OUT...PREFER A
SIMPLE RAIN/SNOW MIX CHANGING MORE TO RAIN IN THE AFTERNOON.
