Area forecast discussion, Apr 25, 3:00 PM CDT, 1 hour 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
300 PM CDT FRI APR 25 2008

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT

IN THE IMMEDIATE TERM...CONVECTION CONTINUES TO FIRE ALONG AND AHEAD
OF A COLD FRONT...WHICH HAS RESULTED IN A TOR WATCH TO ACCOUNT FOR
INCREASING INSTABILITY AND GOOD WIND SHEAR. THESE SHOWERS/STORMS
SHOULD BE NEARLY ALL EAST OF THE LOCAL AREA BY 7 PM...AND ONLY
AFFECT AREAS EAST OF THE MISSISSIPPI RIVER.

CLOSED 500 MB LOW AND SHORTWAVE ENERGY WILL CONTINUE TO LIFT
NORTHEAST TONIGHT...PUSHING THE SFC LOW AND FRONT EAST/NORTHEAST AS
IT DOES. GOOD WRAP AROUND OF MOISTURE INTO THE DEFORMATION AREA WEST
OF THE LOW THOUGH WILL CONTINUE PCPN CHANCES POST THE LOW. CURRENT
TRACK OF THE SYSTEM WOULD KEEP THE BETTER CHANCES ACROSS MN
THOUGH...MOSTLY WEST AND NORTH OF THE LOCAL AREA. MUCH OF THIS PCPN
WILL LIKELY FALL AS SNOW...AS CONSIDERABLE INFLUX OF COLD AIR IS
FOLLOWING IN THE WAKE OF THIS SYSTEM. WILL CONTINUE SOME SMALL PCPN
CHANCES FOR PORTIONS OF THE AREA TONIGHT...BUT DON/T EXPECT MUCH/IF
ANY SNOW ACCUMULATION.

BY SAT NIGHT...A COUPLE SHORTWAVE TROUGHS WILL TRACK SOUTHEAST
THROUGH THE NORTHERN PLAINS...PUSHING ACROSS THE UPPER/MID
MISSISSIPPI RIVER VALLEY ON SUNDAY. THERE WILL BE SOME SFC
CYCLOGENESIS WITH THE SOUTHERN WAVE...AS A LOW IS PROGGED TO DEVELOP
OUT AHEAD OF THE UPPER LEVEL FORCING...MOVING ACROSS THE OH RIVER
VALLEY/EASTERN GREAT LAKES BY 00Z MON. DECENT QG CONVERGENCE THROUGH
300-850 MB WITH THE UPPER LEVEL ENERGY...AND A SLUG OF ISENTROPIC
UPGLIDE ON THE 290-315 K SFCS FROM 06Z-18Z SUN. MEANWHILE AT THE
SFC...AN INVERTED TROUGH LOOKS TO EXTEND NORTHWEST OF THE SFC
LOW...AND BACK INTO THE LOCAL AREA. ALL THIS SHOULD RESULT IN SOME
AREAS OF PCPN DEVELOPING ACROSS THE CENTRAL PLAINS...MOVING EAST
ACROSS IOWA...INTO NORTHERN ILL/SOUTHEAST WI. JUST HOW FAR NORTH THE
NORTHERN EXTENT OF THESE CHANCES WILL LIE IS HAZY...BUT THE BEST
LOCAL CHANCES SHOULD BE CONFINED TO NORTHEAST IA/SOUTHWEST WI. AS
MENTIONED...A GOOD AMOUNT OF COLD AIR WILL BE FUNNELING ACROSS THE
REGION BEHIND THE DEPARTING SYSTEM TONIGHT...WITH 850 MB TEMPS BELOW
ZERO INTO NEXT WEEK. LOOKING AT A NORTH-SOUTH RUNNING X-SECTION FROM
SAT NIGHT THROUGH SUN SHOWS A GOOD AMOUNT OF COLD AIR FOR THE LIFT
TO WORK WITH...ALTHOUGH SOME SHALLOW WARMER AIR NEAR/AT THE SFC.
CURRENT HIGHS FOR SUN SHOULD BE IN THE 40S. SO...IF THE SYSTEM KEEPS
ITS CURRENT PACE...SOME SNOW CHANCES WOULD MOVE IN OVERNIGHT
SAT...CHANGING OVER TO RAIN LATER THAT MORNING. WITH GROUNDS VERY
WET AND WARM...DON/T EXPECT MUCH IF ANY SNOW ACCUMULATION.

A 500 MB CLOSED LOW WILL DEVELOP AS THE MEAN TROUGH MOVES THROUGH
SUN NIGHT...WHILE A SFC HIGH STARTS TO BUILD IN FROM THE NORTHERN
PLAINS. THE AREA WILL BATTLE THE CYCLONIC FLOW ALOFT AND THE
SUBSIDENCE FROM THE HIGH ON SUN NIGHT/MON...WITH AREAS EAST OF THE
MISSISSIPPI RIVER DEALING WITH MORE CLOUDS...WHILE TO THE WEST THOSE
AREAS WILL HAVE TO BEST SHOT FOR MORE SUNSHINE.

.LONG TERM...TUESDAY THROUGH FRIDAY

VERY INTERESTING UPPER LEVEL PATTERN SETTING UP FOR NEXT WEEK...AND
THE MEDIUM RANGE GFS AND EC LOOKING VERY SIMILAR IN THEIR HANDLING
FOR THE MOST PART. THE WEEKEND TROUGH CONTINUES TO SWING EAST OVER
THE NEW ENGLAND STATES...STRENGTHENING AND DEEPENING AS IT GOES. THE
CLOSED 500 MB STALLS...AND THEN RETROGRADES BACK WEST AS A 300 MB
JET MAX WRAPS AROUND IT...SHOOTING NORTHWEST. MEANWHILE...OUT WEST A
TROUGH WILL DRIVE INTO THE NORTHERN ROCKIES...WITH JUST A WEAK RIDGE
ACROSS THE LOCAL AREA FOR TUES/WED. THE EC HAS BEEN FAIRLY
CONSISTENT WITH THIS PATTERN OVER ITS LAST FEW RUNS...WITH THE GFS
NOW TRENDING TOWARD THE EC. TOWARD THE END OF THE NEW WORK WEEK THE
MODELS STRAY A BIT...WITH THE GFS BRINGING THAT WEST COAST TROUGH
MORE ACROSS THE LOCAL AREA...WHILE THE EC TRACKS IT MORE SOUTH...BUT
BRINGS ENERGY FROM THE EAST BACK ACROSS THE UPPER MISSISSIPPI RIVER
VALLEY. THE GFS WOULD BRING WET WEATHER BACK FOR THU/FRI...WHILE THE
EC WOULD KEEP IT MOSTLY DRY. AGAIN...A MESSY PATTERN AND CONFIDENCE
ISN/T PARTICULARLY HIGH WITH THIS SCENARIO...BUT WILL CONTINUE
SMALL PCPN CHANCES FOR THU/FRI...VIA THE GFS SOLUTION.
OVERALL...THERE SHOULD BE AT LEAST A SHORT BREAK FROM THE RECENT WET
WEATHER EARLY NEXT WEEK...WITH TEMPERATURES AT OR BELOW THE
SEASONABLE NORMALS.

&&

.AVIATION...

A COLD FRONT WILL PRODUCE SHOWERS AND THUNDERSTORMS AS IT MOVES EAST
THROUGH WESTERN WISCONSIN THIS AFTERNOON. IT IS STILL UNCLEAR
WHETHER KLSE WILL SEE ANY THUNDERSTORMS...SO I LEFT THE MENTION OUT
OF THE TAF. I WILL MONITOR THIS THROUGH THE REMAINDER OF THIS
AFTERNOON AND I WILL ADD IT TO THE TAF IF NEEDED.

MVFR TO IFR CEILINGS ARE BEING OBSERVED ON THE BACK SIDE OF THIS
SYSTEM...AND THIS HAS ALREADY MOVED INTO KRST AND IT WILL MOVE INTO
KLSE AFTER 23Z FRIDAY. THESE LOW CLOUDS WILL PERSIST THROUGH AT LEAST
18Z SATURDAY.

BOYNE

&&

.HYDROLOGY...
ONE MORE SHOT OF SHOWERS/STORMS WITH HEAVY RAIN POTENTIAL EARLY THIS
EVENING...AS CONVECTION CONTINUES TO FIRE ALONG AND AHEAD OF THE
COLD FRONT. ANOTHER QUICK 1/2 INCH IS ENTIRELY POSSIBLE WITH ANY
THUNDERSTORM...WITH A LOCAL INCH NOT OUT OF THE QUESTION. WILL BE
ABLE TO DROP SOME WESTERN COUNTIES FROM THE CURRENT FLOOD
WATCH...BUT WILL CONTINUE THE REST THROUGH 6 PM. BY THIS TIME...THE
STORMS SHOULD HAVE EXITED EAST OF THE AREA...LESSENING THE FLOODING
THREAT FROM ADDITIONAL RAIN. MANY RIVERS THAT WERE EXPERIENCING
FLOODING HAVE CRESTED...OR ARE NEARING CREST. THE FLOODING SHOULD
START TO...OR CONTINUE TO...IMPROVE THIS EVENING ACROSS PORTIONS OF
NORTHEAST IA/SOUTHWEST WI.
