AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
358 AM CDT WED APR 13 2011

.SYNOPSIS...TURNING COLDER. WET WX LIKELY RETURNING FOR THIS
WEEKEND...AND POSSIBLY AGAIN DURING THE MIDDLE OF NEXT WK.

CONSIDERABLE CHGS EXPECTED TO THE UPPER PATTERN ACRS NOAM DURING
THE FIRST HALF OF THE FCST PERIOD. STG AMPLIFICATION WL CONT OVER
THE ERN PAC THE NEXT FEW DAYS...WITH FLOW EVENTUALLY EVOLVING INTO
FULL BLOWN REX BLOCK. THE BRANCH OF THE JET FLOWING ARND THE SRN
SIDE OF THE BLOCK WL EDGE OVER FLAT RIDGING NR THE WEST COAST...
THEN TURN ESE AND CARVE OUT UPR TROF OVER THE CENTRAL CONUS.
MEANWHILE...THE BRANCH OF THE WESTERLIES FLOWING ARND NRN PORTION
OF THE BLOCK WL HEAD SE ACRS CANADA...GENERATING A STG CONFLUENT
ZONE WHERE IT REJOINS THE SRN STREAM OVER ERN CANADA. DURING THE
LATTER HALF OF THE FCST PERIOD...PATTERN ACRS NOAM EXPECTED TO
GRADUALLY EVOLVE TOWARD HAVING BROAD/FAIRLY DEEP TROF OVER MOST
OF THE CONTINENT...WITH RIDGES NEAR THE COASTS.

EARLY ON...EXPANSIVE AREA OF HIGH PRESSURE WL GET STRUNG OUT FM
THE YUKON TO THE THE HUDSON BAY AREA...AND FEED THE COLD AND VERY
DRY AIR SWD INTO THE NRN CONUS. THAT WL HAVE IMPLICATIONS ON JUST
HOW FAST PCPN WITH SLOWLY EVOLOVING SRN STREAM CYCLONE WORKS INTO
THE FCST AREA...AND POSSIBLY ON PCPN TYPE.

TEMPS WL TURN COLDER TDA/TNGT...THEN AS FCST AREA REMAINS NR BASE
OF FAIRLY DEEP UPR TROF THE REST OF THE PERIOD...READINGS SHOULD
REMAIN AOB NORMAL. EXPECT A SIG PCPN EVENT THIS WEEKEND AS SLOW
MOVG SRN STREAM CYCLONE CROSSES THE RGN. A SECOND EVENT POSSIBLE
DURING THE MIDDLE OF NEXT WK...THOUGH MORE UNCERTAINTY WITH THAT.
PCPN AMNTS WL PROBABLY END UP AOA NORMAL FOR THE PERIOD.
&&

.SHORT TERM...TDA/TNGT/THU. PCPN OUT THERE RIGHT NOW NOT VERY
IMPRESSIVE. LOW-LEVELS QUITE DRY AND STILL PRIMARILY JUST MID-
CLDS WITH THE PCPN. WL MAINTAIN CHC POPS ACRS THE N...BUT MAY JUST
END UP WITH SPRINKLES AT MOST LOCATIONS. TRIMMED/DLAD PCPN ACRS
THE SE. THE AIR AHEAD OF THE FRONT WL BE RATHER MILD...BUT
SUNSHINE WL BE LIMITED BY EXTENSIVE AREA OF HIGH AC THAT WL STREAM
ACRS FM THE SW. STAYED CLOSE TO PREV FCST FOR MAX TEMPS.

LOOKS LIKE A LITTLE BETTER FORCING TO ARRIVE LATE TDA/OVERNIGHT.
NOTHING REAL STG BY ITSELF...BUT COMBO OF DIV BTWN BRANCHES OF UPR
JET...TAIL OF NRN STREAM SHRTWV...WEAK QG...AND WK FRONTOGENETIC
FORCING LIKELY TO RESULT IN SOME UPTICK IN THE LIFT/PCPN. SHIFTED
MAX POPS...THOUGH STILL IN CHC CATEGORY...SWD SOME AS BY THEN THE
N SHOULD BE STARTING TO DRY OUT. COULD STILL BE SOME SHSN OR
FLURRIES ALONG THE NRN EDGE OF THE PCPN AS COLDER AIR ARRIVES SWD.

LINGERING PCPN SHOULD SHIFT SW AND OUT OF THE AREA THU. WENT MORE
AGGRESSIVE WITH CLEARING FM THE N DURING THE DAY. COULD BE SOME
HIGH CLDS LINGERING...BUT LOW AND MIDDLE LEVELS SHOULD CLEAR OUT
OVER AT LEAST THE NRN 1/3 OF THE FCST AREA

EXPECT COLD FRONT AT THE LEADING EDGE OF THE CANADIAN AIR TO SURGE
SSWWD OVER THE BAY/LAKE...AND ERN WI...STARTING LATE THIS AFTN
AND FINALLY CLEARING THE AREA THIS EVENING. THIS COULD COME
THROUGH AS A PNEUMONIA FRONT...WITH A SHARP DROP IN TEMPS AND
SUDDEN WIND SHIFT TO THE NE WITH STG GUSTS. WL ISSUE SC.Y
STARTING AT 22Z TO ATTEMPT TO CAPTURE THE STG WIND GUSTS RIGHT
BEHIND THE FRONT. WINDS WL PROBABLY SETTLE BACK FOR A WHILE...BUT
WILL INCR AGAIN AS THE HIGH CONTS TO BUILDS SEWD ACRS SRN CANADA
AND CYCLONE DEVELOPS OVER THE PLAINS. WAVES WL ALSO EVENTUALLY
INCREASE TO SC.Y LEVELS. SO WL JUST RUN THE SC.Y THROUGH END OF
THE NSH PERIOD.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY
ONE TRANQUIL NIGHT IS IN STORE BEFORE FORECAST BECOMES COMPLICATED
THROUGH MUCH OF THE FORECAST PERIOD. ON THURSDAY NIGHT...DRY
EASTERLY FLOW FROM CANADIAN HIGH AND 500MB RIDGE AXIS WILL KEEP
THE AREA DRY. WITH SYSTEM WELL TO THE SOUTH AND RIDGING
OVERHEAD...HAVE LOWERED CLOUD COVER AND LOWERED MIN TEMPERATURES A
FEW DEGREES THINKING THERE WILL BE LESS CLOUD COVER. ON
FRIDAY...SYSTEM ACROSS THE SOUTHERN PLAINS WILL WORK TOWARDS
WISCONSIN. PRECIPITATION AHEAD OF IT WILL HAVE TO FIGHT DRY
EASTERLY FLOW WHICH WOULD SUPPORT A SLOWER ARRIVAL TO THE AREA.
THE NEW WRF/ECMWF HAVE FOLLOWED THIS TREND AND HAVE DECIDED TO
DELAY THE ONSET OF THE PRECIPITATION. WILL KEEP FRIDAY MORNING
DRY...THEN ADDED A CHANCE OF RAIN FRIDAY AFTERNOON. STRONG
EASTERLY WINDS ARE EXPECTED AHEAD OF APPROACHING SYSTEM WITH WINDY
CONDITIONS EXPECTED WITH GUSTS AROUND 35 MPH. HIGHS WILL REMAINS
IN THE 30S ALONG THE LAKE AND BAY WITH READINGS INLAND IN THE 40S.
WARMEST READINGS WILL BE FOUND ACROSS NORTH CENTRAL WISCONSIN WITH
MORE SUNSHINE EXPECTED.

THE STORM AND ITS ASSOCIATED PRECIPITATION WILL CONTINUE TO WORK
NORTHWARD INTO THE AREA DURING THE EVENING. WILL HAVE CHANCE POPS
ACROSS THE NORTH WITH CATEGORICAL OVER THE SOUTH...THEN CATEGORICAL
POPS EVERYWHERE AFTER MIDNIGHT. 12Z APR 12 AND 00 APR 13 MODELS
RUNS SHIFTED SYSTEM A LITTLE FURTHER NORTH AND ARE CONSIDERABLY
WARMER THAN LAST NIGHT. STILL MANY QUESTIONS LINGER DUE TO
EVAPORATIVE COOLING ISSUES AND AMOUNT OF A WARM AIR WORKING INTO
THE REGION DURING THE NIGHT. LATEST 00Z GFS ENSEMBLE MEMBERS
INDICATED THAT PRECIPITATION ON THIS RUN SHOULD BE MAINLY RAIN
ACROSS GREEN BAY...THE FOX CITIES EAST TO THE LAKE. PRECIPITATION
TYPES BECOME MURKY AS GFS ENSEMBLE MEMBERS PROBABILITIES NOT AS
HIGH FOR ANY ONE TYPE OF PRECIPITATION AS SOME MEMBERS WOULD FAVOR
MORE RAIN THAN SNOW WHILE OTHER FAVORED MORE SNOW. LOOKING AT THE
SREF ENSEMBLE MEMBERS...THERE ARE SOME MEMBERS HANGING ONTO THE
COLDER BIAS...THEREFORE LATER MODEL RUNS MAY SHOW SOME SHIFTING
OF THE RAIN SNOW LINE. THE OPERATIONAL WRF MODEL WAS THE MOST
BULLISH WITH WARM AIR AROUND 850MB WORKING INTO CENTRAL AND NORTH
CENTRAL WISCONSIN. WILL HAVE MAINLY RAIN/SNOW MIX NORTH AND WEST
OF GREEN BAY AND THE FOX CITIES. AT THIS TIME...THE BEST CHANCE
FOR AN ACCUMULATING SNOWFALL WILL BE NORTH AND WEST OF A WISCONSIN
RAPIDS TO IRON MOUNTAIN LINE... HOWEVER IT IS EXPECTED TO CHANGE
SOME OVER THE NEXT FEW MODEL RUNS.

PRECIPITATION TYPE ISSUES LINGER INTO SATURDAY MORNING DEPENDING
ON THE MODEL OF CHOICE DUE TO AMOUNT OF WARM AIR PULLED INTO THE
SYSTEM. WENT WITH A RAIN SNOW MIX MOST PLACES EXCEPT FAR NORTH
WHERE I WENT ALL SNOW. AS FAR AS ACCUMULATIONS ARE CONCERNED
BETWEEN FRIDAY NIGHT AND SATURDAY...IT IS STILL UP IN THE AIR
DEPENDING ON WHICH PRECIPITATION TYPE DOMINATES. IF MORE SNOW
FALL...COULD BE 3 TO 6 INCHES OVER THE FAR NORTH IF EVERYTHING
WORKS OUT. PRECIPITATION SHOULD BEGIN TO DIMINISH OR END DURING
THE LATER SATURDAY AFTERNOON AND EVENING AS SYSTEM PULLS AWAY. DRY
CONDITIONS ARE EXPECTED ON MONDAY.

MODELS NOW SHOWING WEAK WARM ADVECTION AS SYSTEM MOVES SOUTH OF
THE AREA SUNDAY NIGHT. ADDED A SMALL CHANCE OF RAIN GENERALLY
SOUTH OF HIGHWAY 29. ON TUESDAY...GFS MODEL WAS INDICATING LOW
PRESSURE NEAR CHICAGO WITH COPIOUS AMOUNTS OF PRECIPITATION.
PERUSAL OF THE GFS ENSEMBLE MEMBERS...THERE WAS NO SUPPORT BY THE
GFS ENSEMBLE SURFACE LOW MODEL POSITIONS OR GFS ENSEMBLE QPF TO
SUPPORT THE OPERATION GFS MODEL. AFTER LOOKING AT THE
CANADIAN/ECMWF...IT APPEARS THE GFS IS TOO FAST AS THE
CANADIAN/ECMWF HAVE THIS SYSTEM MOVING IN THE SAME GENERAL
LOCATION ON WEDNESDAY.
&&

.AVIATION...THUS FAR...CIGS ASSOC WITH AREA OF SHRA OVER MN HAVE
HELD UP WELL...WITH VFR CONDITIONS PREVAILING. THAT WL PROBABLY
STILL BE THE CASE EARLY TDA AS THE CLOUD BAND MOVES INTO NRN WI.
BUT EXPECT CIGS TO EDGE DOWNWARD TNGT AS PCPN INCREASES A BIT
ALONG THE FRONT.
&&

.MARINE...SMALL CRAFT ADVISORY IN EFFECT FROM 5 PM THIS AFTERNOON
THROUGH THURSDAY NIGHT FOR PERSISTENT NORTHEAST FLOW. EASTERLY
FLOW EXPECTED TO INCREASE ON FRIDAY. GALE FORCE GUSTS ARE POSSIBLE
FRIDAY INTO SATURDAY. ADDITIONAL MARINE HEADLINES ARE EXPECTED
DURING THIS PERIOD.
&&

.HYDROLOGY...MOST RIVERS HAVE CRESTED OR ARE CRESTING...AND
STARTING TO HEAD BACK DOWN. THAT SHOULD GIVE US SOME ROOM TO
HANDLE THE WATER THAT WL END UP IN THE RIVERS FM PCPN BROUGHT BY
THE WEEKEND STORM. DELAY IN ARRIVAL OF THE PCPN WL ALSO HELP. IN
ADDITION...THE GROUND IS THAWED OR CLOSE TO BEING THAWED...AND THE
SNOW MELT IS PRETTY MUCH OVER. SO ALTHOUGH RIVERS MAY HEAD BACK UP
THIS WEEKEND...AT THIS POINT IT APPEARS THAT ANY CRESTS WL BE BLO
WHAT WE/VE SEEN THE PAST FEW DAYS.

FINAL CONCERN IS THE LINGERING ICE ON THE BAY AND LAKE WINNEBAGO.
STLT IMAGERY FM TUE INDICATED ICE COVERING ABOUT 1/3 OF LAKE
WINNEBAGO...AND LOCATED ALONG THE NERN SHORE. MOST OF THE BAY WAS
ICE FREE...BUT 2 SIG PATCHES OF ICE REMAINED. ONE WAS FM
DYCKESVILLE TO NAMUR...WITH ANOTHER FM STURGEON BAY TO EGG HARBOR.
IT/S NOT CLEAR WHETHER THE ICE ON THE BAY AND LAKE WINNEBAGO WAS
ATTACHED TO SHORE OR JUST DRIFTING AROUND WITH THE WIND. IF IT IS
DRIFTING...OR GETS DETACHED AND STARTS DRIFTING...THERE IS SOME
POTENTIAL FOR ICE SHOVES INTO THE FAR SRN PART OF THE BAY OF GREEN
BAY...AND THE WEST SHORE OF LAKE WINNEBAGO FM OSH SWD...WHEN NE
WINDS PICK UP STARTING TNGT AND CONTINUING FOR SEVERAL DAYS. WINDS
MAY NOT BE STG ENOUGH TO GUARANTEE SIG ICE SHOVES...BUT SITN WL
NEED TO BE WATCHED. WL ISSUE SPS ON THIS POSSIBILITY.

.GRB WATCHES/WARNINGS/ADVISORIES...
