AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
351 PM CDT THU OCT 22 2009

.SHORT TERM...TONIGHT AND FRIDAY. PRECIPITATION AREA DID NOT GET
TOO FAR SOUTH TODAY...BEFORE BEGINNING TO LIFT BACK TO THE NORTH
LATE THIS AFTERNOON. CLOUDS HUNG IN TIGHT TODAY...WITH MID/HIGH
LEVEL CLOUDS QUICKLY OVER TAKING THE STATE. TEMPERATURES NEVER
GOT OUT OF THE UPPER 30S NORTH CENTRAL. FORECAST CONCERNS
TONIGHT ARE THE EFFECTS THESE TEMPERATURES WILL HAVE ON PCPN TYPE FORECAST.

UPPER LOW OVER CENTRAL PLAINS TO LIFT NORTH THROUGH THE STATE THIS
PERIOD AS SHORT WAVE TROF SHIFTS EAST ALONG CANADIAN BORDER.
MODELS SUGGEST SOME PHASING BETWEEN SYSTEMS...WITH MAJORITY OF
MODELS PRODUCING DEEPER LOW THAN PREVIOUSLY FORECAST. STRONG
ISENTROPIC FORCING EXPECTED OVERNIGHT AND FRIDAY...WITH
WIDESPREAD PCPN TO OVERSPREAD REGION TONIGHT. BUFKIT SOUNDINGS OFF
BOTH GFS AND NAM INDICATE DRY AIR IN PLACE OVER THE NORTH. WITH
CURRENT SURFACE TEMPERATURE TRENDS AND EVAPORATE
COOLING...EXPECT WILL SEE SOME SNOW MIXING IN AT START LATE
TONIGHT/FRI MORN OVER THE NORTH...THOUGH IT IS EXPECTED TO QUICKLY
CHANGE TO RAIN FRI MORNING AS LOW LEVELS WARM. TEMPERATURE
PROFILES BEGIN TO COLAPSE LATE IN THE DAY OVER THE
NORTHWEST/WEST...FOR SOME SNOW MIXING BACK IN. HAVE LIMITED ANY
ACCUMULATIONS TO LESS THAN AN INCH THROUGHOUT THIS TIME FRAME.

.LONG TERM...FRIDAY NIGHT THROUGH NEXT THURSDAY.

MODEL SOLUTIONS WERE IN CLOSER AGREEMENT ON THE TRACK OF THE
SURFACE LOW THAT WAS EXITING THE SOUTHERN PLAINS THIS
AFTERNOON. AND WITH THEIR PHASING OF THE 500MB CLOSED LOW OVER
KANSAS WITH A LOW AMPLITUDE TROUGH ACROSS THE NORTHERN CONUS.

SNOW AMOUNTS ACROSS NORTHERN WISCONSIN ARE STILL A MAJOR SOURCE OF
CONCERN ON FRIDAY NIGHT AS COLD AIR WRAPS AROUND THE SURFACE LOW
AND THE LONG WAVE UPPER TROUGH AXIS REACHES WISCONSIN.
TEMPERATURES AND AMOUNT OF QPF REMAIN A CHALLENGE. HPC
COLLABORATION GRAPHICS HAD AT LEAST ONE INCH OF SNOW ACROSS THE
CWA...AND 2 TO LESS THAN 4 INCHES OVER THE NORTHWEST HALF...DURING
THE 00Z SAT-00Z SUN PERIOD. COBB SNOWFALL ALGORITHM OUTPUT FOR
RHINELANDER SHOWED AN INCREASE FOR THAT PERIOD OVER THE PAST THREE
RUNS OF THE NAM AND GFS. BASED ON THESE FACTORS AND SURROUNDING
SNOWFALL GRIDS...HAVE 1 TO 2 INCHES FRIDAY NIGHT FOR NORTH-CENTRAL
WISCONSIN. WENT FOR LESS THAN AN INCH IN LOCATIONS TO THE EAST AND
SOUTH...AND NO SNOW IN THE LAKESHORE ZONES WHERE TEMPERATURES
SHOULD REMAIN WARM ENOUGH TO KEEP PRECIPITATION IN THE FORM OF
RAIN. THINK MOST OF THE PRECIPITATION WILL BE PRIOR TO 06Z
SATURDAY BUT GRADUALLY HAVE IT WINDING DOWN TO CHANCE POPS IN THE
12Z-18Z SATURDAY PERIOD AS THE UPPER TROUGH AXIS PASSES EAST OF
THE AREA.

WEAK SURFACE RIDGE AND UPPER LEVEL RIDGE SHOULD ACT TO KEEP THE
AREA DRY FOR SATURDAY NIGHT...BEFORE THE NEXT SYSTEM APPROACHES
THE AREA FROM THE WEST. HAVE CONFINED POPS TO CENTRAL AND NORTH CENTRAL
WISCONSIN SUNDAY BEFORE EXPANDING TO INCLUDE THE REST OF THE CWA.
WARM AIR AHEAD OF THE SYSTEM SHOULD KEEP PRECIPITATION IN LIQUID
FORM ON SUNDAY...BUT HAVE RAIN AND SNOW IN THE NORTH SUNDAY NIGHT
AS COLD AIR MOVES INTO THAT PART OF THE STATE.
IN. LITTLE CHANGES MADE TO THE REMAINDER OF THE FORECAST.
&&

.AVIATION...MVFR CIGS THIS EVENING WILL LOWER INTO IFR/LIFR CAT
WITH LARGE AREA OF RAIN LIFTING NORTH INTO THE STATE AS LOW PRESSURE
APPROACHES THE STATE. STRONG PRESSURE GRADIENT AHEAD OF LOW TO
PRODUCE STRONG EAST WINDS MUCH OF FRI.
&&

.MARINE...

A DEEPENING LOW PRESSURE SYSTEM WILL LIFT TO THE NORTHEAST INTO
LOWER LAKE MI BY FRI AFTN. STRONG EAST WINDS ARE EXPECTED AHEAD OF THE
LOW...PRODUCING GALE CONDITIONS OVER THE LAKE ON FRI.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
