AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
335 PM CDT SAT APR 7 2012

.SYNOPSIS...RELATIVELY QUIET WEATHER FOR THE NEXT WEEK...WITH
TEMPERATURES NEAR NORMAL AND ONLY SCT LGT PCPN.

FAIRLY HIGH AMPLITUDE FLOW REGIME WL CONT ACRS NOAM DURING THE
PERIOD...WITH DEEP UPR TROF FORMING OVER SERN CANADA AND THE NERN
CONUS AND RIDGING INCRG OVER THE INTERMOUNTAIN WEST BY EARLY IN
THE WK. THE PATTERN WL BE SLOWLY PROGRESSIVE AFTER THAT...WITH THE
NEXT UPSTREAM TROF EVENTUALLY REACHING THE SRN ROCKIES BY THE END
OF THE PERIOD.

DEVELOPING NWLY UPR FLOW INTO THE ERN NOAM TROF WL PROVIDE A
PERSISTENT FEED OF COOL CANADIAN AIR INTO THE AREA...AND LEAVE
TEMPS CLOSE TO SEASONAL NORMALS. AFTER SOME LGT PCPN TNGT...NOT
MUCH PROSPECT FOR SIG WIDESPREAD PCPN UNTIL NEXT UPR TROF REACHES
THE AREA...LIKELY BEYOND THE END OF THE FCST PERIOD.
&&

.SHORT TERM...TONIGHT AND SUNDAY.

NUMEROUS ISSUES WITH WHICH TO DEAL IN THE SHORT TERM. CLOUDS WERE
INCREASING AHEAD OF PRECIPITATION IN ADVANCE OF AN APPROACHING
COLD FRONT. THE 12Z GRB SOUNDING SHOWED PLENTY OF DRY AIR AT LOW
LEVELS...BUT RAIN WAS REACHING THE GROUND IN MINNESOTA AND WESTERN
WISCONSIN. SO WOULD EXPECT MEASURABLE PRECIPITATION ACROSS THE AREA...BUT
AMOUNTS WILL PROBABLY BE SMALL. WEST WINDS PICK UP BEHIND THE
FRONT LATER TONIGHT SO MIXING SHOULD KEEP TEMPERATURES FROM
DROPPING LIKE A ROCK...EVEN UNDER MOSTLY CLEAR SKIES. NORTHERN
PARTS OF THE AREA MAY FALL TO OR SLIGHTLY BELOW FREEZING...BUT
WINDS WILL KEEP FROST FROM DEVELOPING AND TEMPERATURES SHOULD NOT
BE COLD ENOUGH FOR FREEZE WARNING.

NOT SURE IF WE WILL SEE ADVISORY CRITERIA WINDS ON SUNDAY...BUT IT
IS NOT OUT OF THE QUESTION WITH DEEP MIXING AND LITTLE TO NO
DIRECTIONAL SHEAR. AM CONCERNED I MAY BE TOO WARM WITH HIGHS ON
SUNDAY SINCE IT WAS ONLY IN THE 40S AND 50S ACROSS THE DAKOTAS AT
20Z TODAY. GENERALLY KEPT CLOSE TO 12Z GFS AND NAM MOS.

.LONG TERM...SUN NGT THROUGH NEXT SAT. COOL CYCLONIC NWLY FLOW
EXPECTED FOR THE START OF THE WORK WEEK. DISTURBANCES WORKING SE
IN THE FLOW COULD GENERATE SOME LGT PCPN AT TIMES...THOUGH IT
WOULD PROBABLY END UP BEING LGT/ TRACE EVENTS. SOME POTENTIAL FOR
LAKE-EFFECT OFF LAKE SUPERIOR...THOUGH TRAJECTORIES WL BE MORE WLY
THAN IDEAL MOST OF THE TIME.

ONCE THE SFC HIGH NEARS THE RGN BY THE MIDDLE OF NEXT WK...WL
PROBABLY SEE DAYS WITH FAIRLY LARGE DIURNAL TEMPERTURE SWINGS DUE
TO MAINLY CLR SKIES...DRY AIR...AND LGT WINDS ACRS THE AREA.
&&

.AVIATION...CIGS...VSBYS AND PCPN AHEAD OF AN APPROACHING COLD
FRONT ARE THE MAIN CONCERNS TODAY INTO THIS EVENING. THE N-S FRONT
WAS THROUGH CENTRAL MN AT TAF ISSUANCE TIME WITH MVFR CIGS EAST
FROM THE FRONT TO EXTREME WESTERN WI. MID CLOUDS SHOULD SPREAD
ACROSS CENTRAL AND EASTERN WISCONSIN DURING THE EARLY AFTERNOON.
THEN MVFR CIGS CAN BE EXPECTED LATER IN THE AFTERNOON WITH SOME
MVFR VSBYS AND IFR CIGS ASSOCIATED WITH SHOWERS DURING THE LATE
AFTERNOON/EVENING AS THE FRONT PUSHES THROUGH THE STATE. STRONG
AND GUSTY WEST WINDS WILL BLOW BEHIND THE FRONT AND VFR CIGS AND
VSBYS ARE EXPECTED THROUGH THE END OF THE TAF PERIOD. MIGHT BE
SOME SPEED SHEAR ISSUES...BUT AM THINKING THERE WILL BE MORE GUSTS
IN SUBSIDENCE BEHIND THE FRONT. SOME VFR CATEGORY CIGS MAY DEVELOP
DURING THE MORNING ON SUNDAY AS THEY DID IN THE DAKOTAS TODAY.
SOME SPRINKLES OR LIGHT SHOWERS CANNOT BE RULED OUT EITHER.

.FIRE WEATHER...MUCH MORE CHALLENGING THAN EXPECTED. TEMPERATURE
CRITERIA FOR RED FLAG WILL NOT BE MET ON SUNDAY BUT WINDS SHOULD
BE A SLAM DUNK. RH VALUES ARE QUESTIONABLE. PLENTY OF CU
DEVELOPED OVER THE NORTHERN PLAINS TODAY SO THE AIR MASS WAS NOT
BONE DRY THERE. GOT GO-AHEAD TO ISSUE A WATCH FOR SUNDAY AFTERNOON
INTO EARLY EVENING AND DECIDED TO GET ON BOARD ALONG WITH THE
SURROUNDING OFFICES AND ISSUE ONE. THIS SHOULD MAKE LIFE A LITTLE
EASIER ON THE MIDNIGHT SHIFT. THEY CAN DROP IT IF THEY FEEL IT IS
NOT NEEDED...OR UPGRADE IF THEY THINK IT IS.
