AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GREEN BAY WI
626 AM CDT TUE SEP 29 2009

.UPDATE...WL BE REPLACING THE HW.W FOR DOOR COUNTY WITH A WI.Y AT
12Z. STILL MEETING WARNING CRITERIA RIGHT NOW...BUT RUC SHOWS
WINDS SHOULD BE STARTING DOWN WITHIN THE NEXT HOUR OR TWO. ALSO...
SFC PRESSURE RISE CENTER NOW WAY OFF TO THE NE. SO...DON/T FEEL
THERE IS A NEED TO EXTEND THE WARNING. UPDATED PRODUCTS WL BE
SHIPPED ARND 7 AM...WHEN THE WARNING EXPIRES.

SKOWRONSKI
&&

.PREV DISCUSSION...ISSUED AT 347 AM CDT TUE SEP 29 2009...

SYNOPSIS...HIGHLY AMPLIFIED BUT PROGRESSIVE UPR PATTERN IN PLACE
ACRS NOAM. PATTERN WL EVOLVE TOWARD A SPLIT FLOW REGIME DURING THE
FIRST HALF OF THE FCST PERIOD AS STG UPR RIDGE BECOMES ESTABLISHED
OVER NRN HUDSON BAY. FCST AREA EXPECTED TO REMAIN PRIMARILY UNDER
THE INFLUENCE OF THE DEVELOPING SRN STREAM.

TEMPS WL START OUT SIG BLO NORMAL...THEN MODERATE BACK TO SLIGHTLY
BLO NORMAL FOR THE BULK OF THE PERIOD. SRN STREAM STORM SYSTEM WL
PROBABLY BRING PCPN TO AT LEAST THE SRN PART OF THE FCST AREA. IT WL
SLOW AS IT REACHES THE AREA...SO SIG PCPN POSSIBLE...ESP ACRS THE
SRN PART OF THE FCST AREA. NEXT SRN STREAM SYSTEM COULD BRING PCPN
TO THE AREA TOWARD THE END OF THE FCST PERIOD.

SHORT TERM...TDA/TNGT/WED. CHILLY AIR NOW IN PLACE ACRS THE RGN.
WINDS HAVE TEMPORARILY DIED DOWN AS BOUNDARY LAYER HAS STABILIZED A
BIT...BUT WINDS SHOULD PICK UP AGAIN LATER TDA AS BOUNDARY LAYER
DESTABILIZES AGAIN. BUT DON/T EXPECT WINDS TO BE AS STG AS YDA...SO
NO HEADLINES NEEDED FOR OTHER THAN THE DOOR. STILL REACHING HW.W
CRITERIA OVER THE NORTHERN DOOR AS COLDER AIR FLOWING ACRS WARMER
BAY HAS MAINTAINED DEEPER MIXING. WINDS ALOFT SHOULD ALREADY BE
STARTING TO DECREASE. ANTICIPATE HOLDING ON TO HW.W UNTIL SCHEDULED
EXPIRATION AT 12Z...THEN REPLACING WITH A WIND ADVISORY. NOT SURE
HOW LONG THAT WL BE NEEDED. THINKING 21Z RIGHT NOW...BUT WL DECIDE
THAT LATER THIS MORNING.

SKIES SHOULD START TO CLEAR THIS AFTN...AND BECOME CLEAR BY EARLY
TNGT AS SFC RIDGE BUILDS IN FM THE N. TEMPS ACRS THE N SHOULD GO
WELL BLO FZG...SO WL POST FZ.W THERE. TEMPS ACRS MOST OF THE REST OF
THE AREA WL BE COLD ENOUGH FOR WIDESPREAD FROST...SO WL POST FR.Y
FOR ALL BUT THE LAKESHORE. WOULD NOT BE SURPRISED TO SEE SOME UPR
20S IN PORTIONS OF CENTRAL WI AS WELL...BUT SINCE WE ARE
BASICALLY LOOKING FOR THE SAME ACTION BY THE PUBLIC IN EITHER CASE
/COVER YOUR PLANTS IF YOU WANT TO SAVE THEM FOR ANOTHER WEEK OR
TWO/ WILL NOT GET TOO TANGLED UP TRYING TO DIFFERENTIATE THE TWO.

850 MB TEMPS START TO RECOVER A BIT ON WED...AND THERE WL BE PLENTY
OF SUN. BUT DON/T REALLY GET INTO A TRUE RETURN FLOW...AND DAY
SHOULD BE OFF TO A COOL START. SO SIDED WITH COOLER GUID TEMPS.

LONG TERM...WEDNESDAY NIGHT THROUGH NEXT MONDAY. THE GFS AND
ECMWF ARE NOW IN GOOD AGREEMENT WITH THE 500MB PATTERN FOR THIS
PERIOD. BOTH FORECAST WEAK UPPER RIDGING WEDNESDAY NIGHT THROUGH
THURSDAY. THE UPPER RIDGE SHOULD PROVIDE SUITABLE CONDITIONS FOR
ANOTHER FROSTY NIGHT WEDNESDAY NIGHT. A FROST OR FREEZE APPEARS
LIKELY AGAIN INLAND FROM THE LAKE AND BAY.

THEN THE MODELS DEEPEN AN UPPER LOW OVER EASTERN NEBRASKA AND
WESTERN IOWA THURSDAY NIGHT. THERE IS A SMALL DIFFERENCE IN TIMING
AND STRENGTH OF THIS UPPER SYSTEM AS IT SLOWLY WEAKENS AND MOVES
ACROSS NORTHERN ILLINOIS FRIDAY AND LOWER MICHIGAN SATURDAY...BUT
IT SHOULD NOT MAKE THAT MUCH DIFFERENCE. GULF MOISTURE STREAMS UP
TOWARDS THE WESTERN GREAT LAKES...SO THERE COULD BE DECENT
OVERUNNING RAINS FRIDAY THROUGH SATURDAY ESPECIALLY OVER THE
SOUTHER HALF OF THE FORECAST AREA. DID NOT INCLUDE THUNDER AT
PRESENT THOUGH A FEW ELEVATED THUNDERSTORMS ARE POSSIBLE. ZONAL
FLOW WITH DRIER CONDITIONS EXPECTED SUNDAY AND MONDAY.

AVIATION...PRIMARILY MVFR CIGS ACRS THE AREA EARLY THIS MORNING.
WOULD ANTICIPATE CLD BASES GRADUALLY LIFTING AND THEN CLOUDS
DISSIPATING FM W-E. SHOULD HAVE MAINLY VFR CONDITIONS BY MID-LATE
AFTN.
