AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
627 AM CDT TUE APR 10 2012

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT
351 AM CDT TUE APR 10 2012

AT 3 AM...CURRENTLY WATCHING THE CLOUDS ACROSS NORTHERN
MINNESOTA...AND NORTHERN AND EASTERN WISCONSIN. OVERALL THE
NAM/WRF AND RUC ARE HANDLING THESE CLOUDS THE BEST...AND THEY ARE
IN GOOD AGREEMENT THAT THESE CLOUDS WILL DRIFT EAST OF THE AREA BY
THE AFTERNOON. THIS IS IN RESPONSE TO THE SURFACE HIGH BUILDING
PUSHING EAST INTO THE FORECAST AREA.

WITH 850 MB TEMPERATURES ABOUT 4C COLDER /AROUND -8C/...HIGH
TEMPERATURES THIS AFTERNOON WILL ONLY CLIMB INTO THE 40S. THIS IS
VERY GOOD AGREEMENT WITH THE CONSALL DATA SET AND ABOUT 5 DEGREE
COOLER THAN THE MOS TEMPERATURES.

FOR TONIGHT...IT LOOKS WE WILL HAVE IDEAL RADIATIVE CONDITIONS
/CLEAR SKIES...LOW DEW POINTS...AND LIGHT WINDS/ FOR TEMPERATURES
TO FALL INTO THE 20S. THERE MAY BE EVEN A FEW TEENS IN THE
CRANBERRY BOGS OF CENTRAL WISCONSIN. AS A RESULT...WE WILL HAVE TO
ISSUE ANOTHER A FREEZE WARNING. TO AVOID ANY CONFUSION...WE PLAN
ON ISSUING THE NEW WARNING AT THE SAME TIME THAT THE OTHER ONE
WILL BE EXPIRING.

ON THURSDAY...THE 10.00Z MODELS ARE MUCH SLOWER AT MOVING THE
UPPER LEVEL RIDGE EAST OF THE AREA. AS A RESULT...THE BEST 925 AND
850 MB MOISTURE TRANSPORT REMAINS WEST OF THE FORECAST AREA. IN
ADDITION...MODEL SOUNDINGS SHOW THAT THERE WILL BE QUITE A BIT OF
DRY AIR ACROSS THE REGION. DUE TO THIS...TOOK OUT THE
PRECIPITATION CHANCES THAT WERE IN THERE FORECAST GRIDS DURING THE
AFTERNOON.

ON THURSDAY NIGHT...THE MODELS ARE CONTINUING TO STRUGGLE ON THE
EASTWARD PROGRESSION OF THE UPPER LEVEL RIDGE THROUGH THE REGION.
AS A RESULT...THERE CONTINUES TO BE TIMING DIFFERENCES OF WHEN THE
PRECIPITATION WILL MOVE INTO THE AREA. THE GFS IS THE FASTEST AND
HAS THE RAIN MOVING INTO THE AREA DURING THE EVENING. BOTH THE GEM
AND NAM/WRF MOVE THE PRECIPITATION INTO THE AREA AFTER MIDNIGHT.
FINALLY...THE ECMWF CONTINUES TO KEEP THE ENTIRE AREA DRY. SINCE
THERE IS STILL A LOT OF UNCERTAINTY...KEPT THE PRECIPITATION
CHANCES MAINLY IN THE 30 TO 50 PERCENT RANGE.

.LONG TERM...FRIDAY THROUGH MONDAY
351 AM CDT TUE APR 10 2012

LIKE THEIR PREDECESSORS...THE 10.00Z MODELS CONTINUE TO SHOW VERY
LITTLE RUN TO RUN CONSISTENCY...SO FORECAST CONFIDENCE IS MUCH
LOWER THAN USUAL.

OVERALL...THE MODELS ARE STILL IN GENERAL AGREEMENT THAT THE
UPPER LEVEL RIDGE WILL MOVE RAPIDLY EAST ACROSS THE AREA BY FRIDAY...
BUT THIS OCCURS A BIT SLOWER THAN WHAT WAS INDICATED EARLIER IN
THE WEEK. AS THIS RIDGE MOVES EAST...A SERIES OF SHORT WAVES EJECT
OUT OF THE WESTERN LONG WAVE TROUGH. THE TIMING OF THESE SYSTEMS
HAVE BEEN SO INCONSISTENT THAT THE PRECIPITATION WAS BROAD
BRUSHED. HOWEVER THIS SET OF MODELS INDICATE THAT THE HIGHER RAIN
CHANCES LOOK TO BE ON FRIDAY NIGHT AND SATURDAY NIGHT. WITH MOST
UNSTABLE CAPES OF 500 TO 1000 J/KG...THERE WILL ENOUGH INSTABILITY
FOR THE DEVELOPMENT OF SOME THUNDERSTORMS TO GO ALONG WITH THE
SHOWERS.

AS WE HEAD INTO EARLY NEXT WEEK...THE MODELS QUICKLY DEVELOP A
SPLIT FLOW. THE SOUTHERN STREAM KEEPS A TROUGH FROM THE CENTRAL
PLAINS INTO THE SOUTHWEST UNITED STATES. MEANWHILE THE NORTHERN
STREAM SYSTEM DIPS DOWN INTO THE NORTHERN GREAT LAKES. THIS WOULD
POTENTIALLY ALLOW ANOTHER COOL CANADIAN HIGH TO MOVE SOUTHWARD
INTO THE UPPER MISSISSIPPI RIVER VALLEY. IT IS THIS TIME PERIOD
WHERE THE CONFIDENCE IS EXTREMELY LOW. MUCH OF THIS HAS TO DEAL
WITH HOW THE MODELS ARE NOT HANDLING A MODERATE TO STRONG MADDEN
JULIAN OSCILLATION /CURRENTLY LOCATED OVER SOUTH AMERICA AND
ATLANTIC/. WITH THE EXCEPTION OF THE JAPANESE METEOROLOGY AGENCY
ENSEMBLE SYSTEM /JMAN/...MOST OF THE GLOBAL MODELS WIPE OUT THIS
MJO RAPIDLY BY EARLY NEXT WEEK. HOWEVER CONSIDERING ITS
STRENGTH...THIS SEEMS RATHER UNLIKELY. AS A RESULT...EXPECT A
BRIEF WARM UP AS WE ENTER PHASE 1 /OVER AFRICA/ BY THIS
WEEKEND...FOLLOWED BY YET ANOTHER COOL DOWN AS THE MJO STARTS INTO
THE WESTERN INDIAN OCEAN /PHASE 2/ BY THE MIDDLE OF NEXT WEEK.

&&

.AVIATION...TODAY AND TONIGHT
627 AM CDT TUE APR 10 2012

A WEAK CYCLONIC FLOW IS STILL IN PLACE OVER THE GREAT LAKES AND
SOME MOISTURE TRAPPED IN THIS FLOW IS RESULTING IN A LAYER OF VFR
CLOUDS ACROSS NORTHERN WISCONSIN INTO EASTERN MINNESOTA. SOME OF
THESE CLOUDS HAVE PRODUCED A CEILING AT BOTH KRGK AND KMSP AND
COULD POSSIBLY ROTATE INTO KLSE BY MID MORNING. HOWEVER...IR
SATELLITE IS SHOWING A SLOW DIMINISHING TREND SO THE CLOUDS COULD
BE NOTHING MORE THAN A SCATTERED DECK BY THE TIME THEY ARRIVE AT
KLSE. DECIDED TO CARRY THE SCATTERED CLOUDS WITH A TEMPO FOR A
BROKEN CEILING FOR A COUPLE OF HOURS DURING THE MID AND LATE
MORNING. ONCE THE INVERSION BREAKS THIS MORNING...BUFKIT FORECAST
SOUNDINGS SHOW ANOTHER DAY WITH DEEP MIXING AT BOTH SITES. THIS
WILL PRODUCE A THIRD STRAIGHT DAY WITH GUSTY NORTHWEST WINDS...BUT
THE WINDS ARE NOT EXPECTED TO BE QUITE AS STRONG AS THE PREVIOUS
TWO DAYS. EXPECTING SUSTAINED SPEEDS TO BE BETWEEN 15 AND 20 KNOTS
WITH GUSTS INTO THE MID 20 KNOT RANGE. THE WINDS WILL DIMINISH
THIS EVENING WITH SUNSET AND AS THE SURFACE RIDGE AXIS GETS CLOSER
TO THE REGION.

&&

.FIRE WEATHER...THROUGH WEDNESDAY
351 AM CDT TUE APR 10 2012

TEMPERATURES WILL BE ANOTHER 5 TO 10 DEGREES COLDER THAN THEY WERE
ON MONDAY AFTERNOON. MEANWHILE THE DEW POINTS WILL BE SIMILAR. AS
A RESULT...THE RELATIVE HUMIDITIES /25 TO 30 PERCENT/ WILL BE A
BIT HIGHER THIS AFTERNOON. THE SUSTAINED WIND SPEEDS WILL BE
SLIGHTLY LOWER /AROUND 20 MPH/ THAN THEY WERE ON MONDAY AFTERNOON
TOO. ALL OF THESE ALONG WITH VERY HIGH TO EXTREME FIRE WEATHER
CONDITIONS WILL LEAD TO ANOTHER CRITICAL FIRE WEATHER DAY /JUST
UNDER RED FLAG WARNING CRITERIA/ FOR TODAY. ANY PLANS FOR OUTDOOR
BURNING SHOULD BE AVOIDED.

ON WEDNESDAY...WE DO NOT MIX QUITE AS DEEP /UP TO 875 MB/ AND THE
DEW POINTS WILL BE SLIGHTLY HIGHER...SO RELATIVE HUMIDITIES WILL
BE CLOSER TO 30 PERCENT. IN ADDITION...THERE WILL BE MUCH LIGHTER
WINDS AS THE HIGH PRESSURE SYSTEM DRIFTS OVERHEAD. WITH LESS WIND
AND SLIGHTLY HIGHER RELATIVE HUMIDITIES...NOT EXPECTING THE RAPID
SPREAD OF ANY FIRES THAT HAPPEN TO DEVELOP.
