AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
424 AM CDT SAT APR 2 2011

.SHORT TERM...TODAY TONIGHT AND SUNDAY. WIDELY SCATTERED RAIN AND
SNOW SHOWERS WILL END TODAY AS NORTHWEST FLOW BRINGS IN DRIER AIR.
THE DRYING WILL NOT LAST LONG...AS STRONG WARM ADVECTION WILL
ARRIVE LATE TONIGHT AND SUNDAY AND BRING PRECIPITATION TO THE
AREA AS STRONG SYSTEM APPROACHES FROM THE NORTHERN PLAINS.

PRECIPITATION TYPE IS A CHALLENGE LATE TONIGHT AND EARLY SUNDAY AS
INITIALLY COLD AND DRY AIR SHOULD ALLOW FOR A PERIOD OF SNOW IN
MOST PLACES. THERE IS AT LEAST A SMALL POSSIBILITY OF SNOW
ADVISORY CRITERIA SNOW (3 INCHES OF MORE) IN THE FAR NORTH BUT
WILL NOT ISSUE AN ADVISORY RIGHT NOW. WILL GO WITH 1 TO 3 INCHES
IN THE FAR NORTH WITH AN INCH OR LESS FURTHER SOUTH. THE SNOW
SHOULD CHANGE TO RAIN ACROSS ALL OF THE AREA SUNDAY AFTERNOON AS
925MB AND 850MB TEMPERATURES RISE ABOVE FREEZING. IN ADDITION TO
THE SNOW AND RAIN THERE MAY BE SOME THUNDER AS MID LEVEL LAPSE
RATES OF 7 TO 8 C/KM EXPECTED OVER ALL BUT THE FAR NORTH.

HIGHS TODAY SHOULD BE PRETTY CLOSE TO NORMAL BUT HIGHS ON SUNDAY
SHOULD BE HELD INTO THE 30S OVER THE NORTH AND ALSO NEAR THE BAY
AND LAKE...WITH LOW 40S ELSEWHERE.

.LONG TERM...SUNDAY NGT THRU NXT FRI. MAIN FCST FOCUS TO BE ON THE
EARLY SPRING STORM STILL TO BE IMPACTING NE WI EARLY IN THE WEEK.
THERE IS ALSO A SECOND WEAKER SYSTEM DUE TO ARRIVE BY MID-WEEK
BRINGING ANOTHER CHC OF PCPN. TEMPS FOR THE MOST PART SHOULD AVG
AT OR SLIGHTLY BLO NORMAL NXT WEEK.

SFC LOW IS EXPECTED TO MOVE ACROSS SRN WI SUNDAY EVENING AND TURN
MORE NE TOWARD NRN SECTIONS OF LWR MI SUNDAY NGT. INITIAL E-SE
WINDS WL BECOME MORE WESTERLY AS THE SFC LOW PUSHES BY AND THE
ASSOCIATED CDFNT SWINGS THRU THE RGN. PCPN TRENDS ARE FCST TO
DIMINISH SUNDAY NGT AS THE MAIN BAND ASSOCIATED WITH ISEN LIFT TO
HAVE ALREADY EXITED NE WI AND BETTER FORCING/LIFT ALONG THE CDFNT
TO BE LOCATED TOWARD THE MID MS VALLEY. PCPN TYPE SHOULD MAINLY BE
IN THE FORM OF RAIN SUNDAY EVENING AND AS COOLER AIR STARTS TO
WRAP INTO THE SYSTEM OVERNIGHT...WE SHOULD SEE MORE SNOW MIX WITH
THE RAIN OVR N-CNTRL/CNTRL WI. PERHAPS UP TO AN INCH OF SLUSHY
ACCUMULATION FOR THE NORTHWOODS.

EVEN AS THE SFC LOW LIFTS NE INTO SE ONTARIO ON MON...THE MAIN UPR
TROF WL BE IN THE PROCESS OF MOVING THRU WI. SUSPECT A DEFORMATION
BAND OF PCPN TO PUSH THRU THE AREA...THUS CHC POPS ARE NEEDED
ACROSS THE ENTIRE FCST AREA. HIGHEST POPS MAY BE OVER N-CNTRL WI
AS WINDS VEER NW LEADING TO THE POSSIBILITY OF SOME LAKE
ENHANCEMENT. 8H TEMPS DROP TO AROUND -6C OVER NRN WI MON
AFTERNOON...THUS FAVOR MORE SNOW THAN RAIN. HOWEVER...ACCUMULATIONS
WL BE MINIMAL SINCE BULK OF MSTR TO HAVE EXITED (MAYBE AN ADDL INCH
AT MOST N-CNTRL). OTHER FEATURE TO WATCH ON MON WL BE THE INCREASE
IN WINDS AS THE SFC LOW DEEPENS TO OUR NE AND HI PRES MOVES INTO
THE PLAINS. POTENTIAL GALE CONDITIONS FOR THE NEARSHORE WATERS
WITH BLUSTERY TO WINDY CONDITIONS INLAND. KEPT MAX TEMPS DOWN BLO
GUID AD CAA TO HAVE TAKEN OVER AND PLENTY OF CLDS TO CONTEND WITH.

CYCLONIC FLOW TO LINGER OVER NE WI MON NGT WITH THE MDLS BRINGING
ONE MORE SHRTWV THRU WI. MSTR BY THIS TIME IS ALL BUT GONE...THUS
AM SKEPTICAL ABOUT PCPN CHCS EVEN WITH WEAK DYNAMICS PROVIDED BY
THE SHRTWV. 'BEST' CHC WOULD APR TO BE VILAS CNTY WHERE WEAK LK
EHNANCEMENT TO PERSIST THRU THE NGT. A WEAK RDG OF HI PRES IS FCST
TO MOVE INTO THE WRN GREAT LKS ON TUE AND BACK THE WINDS ENUF SUCH
THAT ANY LK EFFECT/ENHANCEMENT WOULD COME TO AN END OVER VILAS
CNTY. WINDS WL ALSO GRADUALLY DIMINISH ON TUE AND WITH SOME MIXED
SUNSHINE...MAX TEMPS SHOULD BE ABLE TO REACH THE LWR TO MID 40S.

AS THIS HI PRES DEPARTS TUE NGT...WINDS WL BACK SE WITH A GRADUAL
INCREASE IN LOW-LVL MSTR. MEANWHILE...A CLIPPER TYPE SYSTEM IS
PROGGED TO MOVE ALONG THE U.S.-CANADIAN BORDER (VCNTY NRN ND/NW
MN) WITH A SWD EXTENDED FNTL BNDRY THRU CNTRL MN. HAVE INCREASED
CLDS THRU THE NGT WITH A SLGT CHC THAT THE LEADING EDGE OF LGT
RAIN OR SNOW COULD REACH CNTRL WI BY DAYBREAK. THIS CLIPPER
REACHES THE WRN GREAT LKS ON WED WITH INCREASING ISEN LIFT
COMBINED WITH LIFT FROM THE FNTL BNDRY. CHC POPS APR NECESSARY
WITIH PERHAPS A MIX NORTH IN THE MORNING AND RAIN EVERYWHERE IN
THE AFTERNOON.

ANOTHER AREA OF HI PRES TO THEN MOVE INTO NRN SECTIONS OF THE
GREAT LKS AND BRING QUIET/COOL CONDITIONS TO NE WI WED NGT. BY
THU...A NEW UPR TROF TO BE AFFECTING THE WRN CONUS AND THE MDLS
ARE SHOWING A LEAD IMPULSE RACING WELL AHEAD ACROSS THE CNTRL
PLAINS. THE TIMING AND MOVEMENT OF THIS IMPULSE VARY AMONG THE
MODELS RANGING FROM THE OHIO RIVER VALLEY TO THE UPR MS VALLEY.
PREFER TO HOLD THU DRY FOR NOW UNTIL THESE DIFFERENCES ARE
RESOLVED. THE UPR TROF CONTS TO DIG OVER THE WRN CONUS BY FRI WITH
MDLS DISAGREEING ON WHEN IT WL BE EJECTED EWD. A FASTER EJECTION
(GFS) WOULD BRING PCPN BACK TO NE WI BY NXT WEEKEND...WHILE A
SLOWER EJECTION WOULD KEEP NE WI ESSENTIALLY DRY. PLENTY OF TIME
TO DISCERN THESE DIFFERENCES IN THE COMING DAYS.
&&

.AVIATION...CIGS AND VSBYS SHOULD IMPROVE TO VFR RANGE THIS
AFTERNOON AND CONTINUE THROUGH THE EVENING HOURS. IFR/LIFR WEATHER
EXPECTED TO ARRIVE FROM SOUTHWEST TO NORTHEAST LATE TONIGHT AND
SUNDAY ALONG WITH SNOW CHANGING TO RAIN. SOME THUNDERSTORMS POSSIBLE
AS WELL.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
