NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 3, 2:08 PM CST, 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 308 PM CDT SUN JUN 3 2007 .SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT MAIN FORECAST CONCERNS REMAIN ON HANDLING OF THE SLOW MOVING LOW SYSTEM THAT HAS BEEN INFLUENCING OUR WEATHER OVER THE PAST SEVERAL DAYS AND ITS IMPACT ON CLOUDS...TEMPERATURES AND PRECIPITATION CHANCES. 18Z DATA ANALYSIS SHOWS VERTICALLY STACKED SYSTEM ACROSS SOUTHWEST WISCONSIN. CONVECTION HAS FIRED ACROSS THE ENTIRE FORECAST AREA WITH CELL MOVEMENT COUNTERCLOCKWISE AROUND THE LOW. WITH THE CLOUDS...INSTABILITIES HAVE BEEN QUITE LOW WITH AROUND 500 J/KG OF SURFACED BASED CAPE...WITH SOME 1000 J/KG ACROSS THE FAR EASTERN COUNTIES. 12Z 03JUN07 MODELS ONCE AGAIN IN GOOD AGREEMENT IN TAKING THE LOW INTO SOUTH CENTRAL WISCONSIN EARLY THIS EVENING AND THEN INTO LOWER MICHIGAN BY MONDAY AFTERNOON. NORTHWEST FLOW IN ITS WAKE THEN PERSISTS THROUGH THE REMAINDER OF THE PERIOD WITH WEAK IMPULSES ROTATING SOUTHWARD ACROSS THE AREA. SOME MODEL DIFFERENCES WITH THE STRENGTH OF THESE WAVES AND NO CLEAR PREFERENCE THUS WILL TAKE A COMPROMISE APPROACH. AS SYSTEM ROTATES EAST OF THE AREA THIS EVENING...SCATTERED TO NUMEROUS CONVECTION WILL CONTINUE INTO THE EVENING HOURS BEFORE WANING AS INSTABILITY DECREASES. WITH WEAK INSTABILITIES AND THE STRONGER SHEAR TO OUR EAST ONLY EXPECT SOME PEA SIZED HAIL ALONG WITH HEAVY DOWNPOURS OF RAIN. POPS TO BE HIGHEST THIS EVENING...BUT REMAINING IN THE CHANCE CATEGORY THROUGH THE OVERNIGHT HOURS IN THE CYCLONIC FLOW. AS SYSTEM MOVES INTO LOWER MICHIGAN ON MONDAY ANOTHER IMPULSE DROPS SOUTHEAST OUT OF CANADA TOWARD THE AREA. AS MENTIONED BEFORE MODELS DIFFER ON STRENGTH WITH THE GFS THE STRONGEST. BOTH SHOWING SOME POTENTIAL VORTICITY ADVECTION BY LATER MONDAY INTO MONDAY NIGHT...WITH THE GFS LINGERING IT INTO TUESDAY. THIS AND REMAINING IN THE CYCLONIC FLOW WILL CONTINUE TO MENTION CHANCE CATEGORY POPS FOR BOTH MONDAY AND MONDAY NIGHT. WEAK HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION TUESDAY AND TUESDAY NIGHT AS THE PRECIPITATION CHANCES GETS PUSHED EASTWARD. THE BREAK WILL BE SHORT LIVED AS YET ANOTHER TROUGH PUSHES INTO THE NORTHERN PLAINS ON WEDNESDAY. WITH CYCLOGENESIS OCCURRING AND STRENGTHENING WARM FRONT ACROSS THE PLAINS WILL BEGIN TO LIFT NORTHWARD TOWARD THE AREA. WARM ADVECTION ALONG WITH STRONG MOISTURE TRANSPORT INTO THE AREA WILL LEAD TO RAIN CHANCES ONCE AGAIN. BEST CHANCES LOOK TO BE WEDNESDAY NIGHT JUST AHEAD OF COLD FRONT. GIVEN STRENGTH OF SYSTEM SEVERE WEATHER THREAT WILL EXIST. THE ONE NEGATIVE IS THE TIME OF DAY WHICH MODELS PROG STRONGEST FORCING DURING THE OVERNIGHT HOURS. WILL HAVE TO WAIT AND SEE WITH LATER MODEL RUNS FOR MORE SPECIFICS. WITH THE UNSETTLED WEATHER OVER THE NEXT SEVERAL DAYS EXPECT TEMPERATURES TO BE NEAR OR SLIGHTLY BELOW NORMALS. HAVE IN GENERAL GONE SLIGHTLY UNDER GUIDANCE THROUGH MUCH OF THE PERIOD. .LONG TERM...THURSDAY THROUGH SUNDAY THE PATTERN IN THIS TIME FRAME WILL BE DOMINATED BY A MEAN WEST COAST TROUGH...WITH NEARLY A ZONAL FLOW ACROSS THE GREAT LAKES. EMBEDDED SHORTWAVES WITHIN THE MEAN WESTERN TROUGH WILL GET EJECTED NORTHEASTWARD THROUGH THE PERIOD. INITIALLY A RATHER POTENT SYSTEM WILL LIFT FROM THE NORTHERN PLAINS INTO SOUTHERN ONTARIO ON THURSDAY. ASSOCIATED FRONTAL BOUNDARY LOOKS TO SWEEP THROUGH THE FORECAST AREA VERY EARLY IN THE PERIOD. QUESTION WILL BE HOW FAR SOUTH FRONT SETTLES FOR THE REMAINDER OF THE PERIOD...AS THESE SHORTWAVES INTERACT WITH THE BOUNDARY TO PRODUCE PRECIPITATION CHANCES. LATEST MODEL GUIDANCE SUGGESTS IT MAY MOVE FAR ENOUGH SOUTH TO ALLOW FOR HIGH PRESSURE TO BUILD IN FOR THE END OF THE WEEK. THIS WOULD KEEP THE RAIN CHANCES FARTHER SOUTH. FOR NOW WILL KEEP CHANCE POPS ON THURSDAY AND THEN CONFINE TO THE POPS TO THE SOUTHERN AREAS FRIDAY THROUGH SATURDAY AND DRY ON SUNDAY. AGAIN DETAILS OF FRONTAL POSITION WILL BE KEY TO OUR CHANCES AND ANY WAFFLING BACK NORTH WOULD RESULT IN HIGHER PROBABILITIES FARTHER NORTH. RABERDING && .AVIATION... SCATTERED TO NUMEROUS CONVECTION IS EXPECTED TO CONTINUE TO BE FOUND ACROSS SOUTHEAST MINNESOTA...NORTHEAST IOWA...AND WESTERN WISCONSIN THROUGH 00Z MONDAY. WITH THE LOSS OF DIURNAL HEATING...THE AREAL COVERAGE OF THE CONVECTION WILL GRADUALLY DECREASE BETWEEN 00Z AND 06Z MONDAY. THE GREATEST CONCENTRATION OF PRECIPITATION WILL BE FOUND ACROSS WISCONSIN DURING THIS TIME PERIOD. THE CONVECTION WILL LIKELY CONTINUE TO CAUSE QUITE VARIABLE CEILINGS ACROSS THE UPPER MISSISSIPPI RIVER VALLEY LATE THIS AFTERNOON AND EARLY EVENING. CEILINGS BETWEEN 03Z AND 15Z MONDAY WILL LIKELY RANGE FROM 1500 TO 3000 FEET. DUE TO THE INCREASING SURFACE PRESSURE GRADIENT ON THE WESTERN PERIPHERY OF THE UPPER LEVEL LOW...THERE IS QUITE A BIT OF UNCERTAINTY ON WHETHER FOG WILL DEVELOP AND IF IT DEVELOPS...HOW LOW WILL THE VISIBILITIES DROP. FOR THE TIME BEING...I LEFT VISIBILITIES ABOVE 6 STATUE MILES...BUT THIS WILL HAVE TO BE WATCHED CLOSELY THIS EVENING. BOYNE && .ARX WATCHES/WARNINGS/ADVISORIES... WI...NONE. MN...NONE. IA...NONE. &&
