AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
339 AM CDT SAT MAY 16 2009

.SYNOPSIS...NEGATIVE HEIGHT ANOMALY WL PERSIST ACRS CENTRAL
CANADA...KEEPING A SEASONABLY STG BAND OF WESTERLIES ACRS SRN
CANADA AND THE NRN UNITED STATES. LNGWV TROF POSN WAS IN THE
PROCESS OF SHIFTG INTO ERN NOAM...WITH RIDGE NR THE WEST COAST.
PATTERN INITIALLY HAD MODEST AMPLITUDE. IT WL SLOWLY LOSE
AMPLITUDE DURING THE FIRST PART OF THE FCST PERIOD...BUT WITH TROF
REMAINING IN THE E AND RIDGE IN THE W. PATTERN WL BECOME
PROGRESSIVE DURING THE SECOND HALF OF THE FCST PERIOD...WITH
SHRTWV AND ASSOC SFC SYSTEM CROSSING SRN CANADA DURING THE LATTER
PART OF THE UPCOMING WORK WEEK.

TEMPS ARE HEADED FOR WELL BLO NORMAL LEVELS AS STG CAA FLOODS SWD
BEHIND SFC SYSTEM EXITING THE RGN. TEMPS WL LIKELY GET INTO A
ROLLERCOASTER PATTERN NEXT WK AS SFC FRONT MOVES BACK AND FORTH ACRS
THE AREA. PROSPECTS FOR PCPN NOT REAL CLR. THERE WL BE CHCS
WHENEVER THE FRONT IS IN THE AREA ...BUT FAST WLY NATURE OF THE
UPR FLOW MAY SOMEWHAT LIMIT THE MOISTURE THAT/S AVBL NEAR THE
FRONT.
&&

.SHORT TERM...TDA/TNGT/SUN. LOTS OF DETAILS TO SORT OUT. FIRST IS
THE WIND TDA. STG PRESSURE GRADIENT...CAA...AND LOW-LEVEL SUBSIDENCE
SHOULD LEAD TO A WINDY DAY. EXPECT TO FLIRT WITH WIND ADVISORY
CRITERIA...BUT SITN NOT CLEAR-CUT ENOUGH TO GO WITH AN ADVISORY AT
THIS POINT. FAIRLY SOLID SC DECK TO THE WEST...BUT THAT SHOULD BREAK
UP SOME DUE TO STG SUBSIDENCE. ON THE OTHER HAND...INCOMING AIR MASS
IS QUITE COLD...SO SHOULD GET DAYTIME CONVECTIVE CLOUDINESS.
SECONDARY SHRTWV BRUSHING THE N COULD LEAD TO SOME SHOWERS THROUGH
MID-DAY. IT WILL EVEN BE COLD ENOUGH THIS MORNING TO GET SOME SNOW
MIXED IN ACRS THE FAR N.

SECOND MAIN ISSUE IS FROST/FREEZE HEADLINE FOR TNGT. COLD AIR WILL
BE AT LEAST SOMEWHAT OFFSET BY WINDS STAYING UP MOST OF THE NGT. BUT
RIDGE WL GET CLOSE ENOUGH LATE TO ALLOW TEMPS IN THE WEST TO DROP
OFF. CONFIDENCE IN GETTING FZG TEMPS HIGH ENOUGH TO UPGRADE ALL OF
THE WATCH PLUS WAUSHARA AND WAUPACA TO FREEZE WARNINGS. QUESTION
IS E-C WI...WHERE WIND MAY NEVER DIE OFF. THOUGHT ABOUT POSTING A
FROST ADVISORY...BUT NOT SURE WE/D GET FROST WITH THE WIND. BETTER
APPROACH SEEMED TO BE TO POST A WATCH FOR ALL REMAINING COUNTIES
BUT DOOR...TO ALLOW THE DAY SHIFT TO SEE HOW TEMPS RESPOND TDA AND
HOW MUCH WINDS WL DROP OFF LATE TNGT. BOTTOM LINE IS TO GET
GARDENERS TO PROTECT THEIR PLANTS...AND THINK WATCH HEADLINE WL DO
THAT.

SUN LOOKS LIKE A MUCH NICER DAY. NEW ECMWF ACTUALLY SPIT OUT A
LITTLE PCPN. LOOKING AT SOUNDINGS...THAT MUST BE COMING OUT OF VERY
HIGH BASED CU. DID NOT ADD ANY PCPN...BUT WENT A BIT CLOUDIER DURING
THE MID-DAY/AFTN...AND ADDED SOME TIMING TO SKYCON GRIDS TO TRY AND
SHOW DIURNAL CONVECTIVE CLOUDINESS FORMING.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY
HIGH PRESSURE WILL SLIDE EAST INTO THE EASTERN GREAT LAKES REGION
SUNDAY NIGHT. RETURN FLOW SETS UP WITH MOST MODELS DEPICTING MID LEVEL
BAND OF CLOUDINESS THAT SHOULD MOVE ACROSS THE REGION SOMETIME
SUNDAY NIGHT. MODELS DIFFER ON HOW QUICK THIS MID DECK WILL MOVE
ACROSS THE REGION. PAST EXPERIENCE ALSO SUGGEST THAT THEY MAY BE TOO
SLOW AS WELL. WILL HAVE BECOMING MOSTLY CLOUDY WORDING TO HANDLE
THIS SCENARIO. COLD FRONT WILL APPROACH WISCONSIN FROM THE NORTHWEST
ON MONDAY AND SHOULD BE NEAR IRON MOUNTAIN TO MINNEAPOLIS LINE BY
00Z TUESDAY. FAIRLY DECENT PRESSURE GRADIENT NOTED ON THE MODELS...
THEREFORE EXPECT WINDY CONDITIONS TO DEVELOP WITH SUSTAINED WINDS
OF 20 TO 30 MPH WITH GUSTS TO 40 MPH ARE POSSIBLE BASED ON THE
MODEL RUNS TONIGHT.

THE COLD FRONT WILL THEN SLIDE ACROSS THE AREA MONDAY NIGHT...
BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS TO THE FORECAST AREA.
MODELS SHOW LITTLE CAPE AND WE ARE NOT IN THE FAVORED REGION OF THE
JET TO SUPPORT SEVERE THUNDERSTORMS. MID LEVEL LAPSE RATES ARE
AROUND 6.5 C/KM TO SUPPORT THUNDERSTORM ACTIVITY. CONTINUED TO KEEP
A SMALL CHANCE OF SHOWERS ON TUESDAY OVER THE SOUTH. IT IS POSSIBLE
A FEW SHOWERS COULD LINGER PAST 12Z TUESDAY.

MODELS DIVERGE ON HOW SOUTH THE FRONT WILL GET ON TUESDAY AND TUESDAY
NIGHT WHICH LEADS TO THE QUESTION OF PRECIPITATION CHANCES. HAVE
TRENDED TOWARD THE GFS FOR PRECIPITATION CHANCES ON TUESDAY NIGHT.
THE 00Z ECMWF TONIGHT WOULD SUGGEST WE WOULD NEED HIGH RAIN
CHANCES AND CHANCES FOR RAIN MUCH FURTHER NORTH. THE ECMWF HAS
PUSHED THE NORTHWARD ADVANCE OF THE WARM FRONT UP TO 12 HOURS
QUICKER THAN THE GFS. DESPITE THE DIFFERENCES...INCLUDED A 30
PERCENT CHANCE OF SHOWERS AND THUNDERSTORMS ON WEDNESDAY. TEMPERATURES
WILL BE TRICKY DEPENDING ON WHERE WARM FRONT SETS UP. GFS WOULD
SUGGEST COOLER CONDITIONS WHILE THE ECMWF INDICATED OUR SOUTHWEST
PORTION OF THE FORECAST AREA COULD GET INTO THE WARM SECTOR .

THE WARM FRONT IS EXPECTED TO MOVE NORTH OF THE AREA BY THURSDAY
MORNING WITH THE FORECAST AREA EXPECTED TO BE IN THE WARM SECTOR
DURING THE MORNING HOURS. COLD FRONT WILL GRADUALLY PUSH THROUGH
THE REGION DURING THE DAY. LATER SHIFTS WILL NEED TO MONITOR FOR
THE POTENTIAL FOR SEVERE WEATHER. COOLER WEATHER WILL RETURN FOR
FRIDAY.
&&

.AVIATION...EXPECT RAPIDLY IMPROVING CONDITIONS TDA...AND VFR
CONDITIONS TNGT.
&&

.MARINE...BUFKIT MOMENTUM TRANSFER TOOL SUGGESTS WE WL GET GALE
FORCE GUSTS. MAX IS ACTUALLY LATE TDA/EARLY TNGT. WL UPGRADE SC.Y
TO GL.W AND EXTEND A LITTLE LONGER INTO THE NGT.
