AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
414 AM CDT TUE SEP 18 2007

.SHORT TERM...UPPER TROUGH OVER THE WESTERN DAKOTAS WILL LIFT
NORTHEAST AND WEAKEN OVER THE NEXT 24 HOURS. THIS WILL PROPEL COLD
FRONT OVER WESTERN MINNESOTA INTO WESTERN WISCONSIN LATE THIS
AFTERNOON AND INTO LAKE MICHIGAN LATE TONIGHT. AIR IS INITIALLY
QUITE DRY AND UPSTREAM WVSS-II (MOISTURE SENSOR) AIRCRAFT
SOUNDINGS FROM ROCKFORD AROUND 07Z SHOW THE AIR IS QUITE DRY DOWN
THERE TOO. WITH FRONT EXPECTED TO MOVE ONLY SLOWLY EASTWARD AND A
MOISTURE CHALLENGED ATMOSPHERE...THINK SHOWERS AND THUNDERSTORMS
AHEAD OF FRONT WILL NOT REACH EASTERN COUNTIES BEFORE DUSK. THIS
SHOULD ALLOW TEMPERATURES TO RISE INTO THE LOW 80S IN EASTERN
WISCONSIN UNDER SUNSHINE FILTERED BY HIGH CLOUDS. FRONT SHOULD
MOVE ACROSS THE AREA OVERNIGHT WITH AT LEAST A CHANCE OF
THUNDERSTORMS EVERYWHERE. BEST DYNAMICS STAY NORTH OF THE FORECAST
AREA...SO BEST CHANCE OF RAIN IN THE NORTH. DRIER AIR RETURNS
WEDNESDAY...THOUGH TEMPERATURES WILL REMAIN ABOVE NORMAL.

.LONG TERM...WEDNESDAY NIGHT THROUGH SATURDAY NIGHT.

PRECIPITATION IS THE MAIN CONCERN DURING THIS PART OF THE
FORECAST. A SURFACE HIGH PRESSURE SYSTEM AND LOW AMPLITUDE UPPER LEVEL
RIDGE ARE EXPECTED TO BE THE DOMINANT FEATURES ACROSS THE REGION
WEDNESDAY NIGHT AND THURSDAY. MEAN 850-700 MB RH PROGS INDICATE
DRY AIR OVER THE AREA SO THESE PERIODS SHOULD REMAIN FREE OF PCPN.
HAVE POPS FOR THURSDAY NIGHT...HIGHEST OVER THE NORTH...AS LOW PRESSURE
OVER CANADA TREKS EAST AND A SIGNIFICANT 500 MB SHORT WAVE MOVES
FROM THE ROCKIES TO THE NORTHERN PLAINS. CHANCE OF THUNDERSTORMS
CONTINUES FRIDAY AS THE SHORT WAVE PASSES THROUGH THE REGION AND
THE LOW DRAGS A FRONT THROUGH WI. HAVE ADDED SLIGHT CHANCE POPS TO
THE GRIDS FOR FRIDAY NIGHT IN THE SOUTHEAST PART OF THE FORECAST
AREA TO DEAL WITH POSSIBLE LINGERING PCPN. SATURDAY AND SATURDAY
NIGHT SHOULD DRY AS HIGH PRESSURE AND A STRONGER UPPER RIDGE BUILD
OVER THE REGION.

MADE SOME ADJUSTMENTS TO TEMPERATURES TOWARD GUIDANCE AND/OR TO
KEEP GRIDS LOOKING PRETTY.
&&

.AVIATION...LLWS IN MOST PLACES UNTIL ABOUT 14Z TODAY WITH LOW
LEVEL JET AROUND 40 TO 50 KNOTS AT 1000 TO 1500 FT AGL. VFR
EXPECTED IN GRB/ATW/SUE THROUGH 00Z WITH MIDDLE AND HIGH CLOUDS.
VFR CONDITIONS AT RHI/EGV/ISW/AUW/CWA WILL GRADUALLY BECOME MVFR
WITH INCREASING CHANCE OF SHOWERS AND THUNDERSTORMS AS THE DAY
GOES BY.
&&

.MARINE...SMALL CRAFT ADVISORIES ARE IN EFFECT THROUGH 12Z
WEDNESDAY MORNING. SOUTH WINDS COULD GUST TO 35 KNOTS AT TIMES
OVER THE NORTHERN PORTION OF THE MARINE AREA THROUGH THIS EVENING.
