AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 648 AM CDT SAT JUN 1 2013 .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 321 AM CDT SAT JUN 1 2013 WHAT REMAINS OF THE CONVECTION IS DIMINISHING SLOWLY ACROSS THE CENTRAL PART OF THE FORECAST AREA. EXPECT THIS TREND TO CONTINUE THROUGH THE REMAINDER OF THE NIGHT. THE 01.05Z HRRR EVEN SUGGESTS THE AREA WILL BE CLEAR OF ANY RAIN BY 12Z AND MAY NEED TO START THE MORNING THAT WAY. AS THE DAY PROGRESSES...THE SURFACE LOW OVER SOUTH DAKOTA MOVES ACROSS MINNESOTA INTO NORTHERN WISCONSIN AS THE UPPER LEVEL LOW BECOMES AN OPEN WAVE. THE SHORT WAVE TROUGH SEEN ON WATER VAPOR SATELLITE OVER SOUTH DAKOTA AND NEBRASKA WILL MOVE ACROSS THE AREA. THE 01.00Z NAM INDICATES THIS WAVE WILL PRODUCE UP TO 12 PVU/S OF VORTICITY ADVECTION IN THE 500-300 MB LAYER DURING THE AFTERNOON. THE AREA WILL GET INTO THE DEFORMATION ON THE BACK SIDE OF THE SURFACE LOW WITH SOME WEAK FRONTOGENESIS DEVELOPING IN THE 1000-850 MB LAYER ALONG WITH SOME WEAK UP GLIDE ON THE 295K SURFACE. THIS IS EXPECTED TO BE ENOUGH TO GENERATE SOME SCATTERED SHOWERS DURING THE AFTERNOON AND WITH BETWEEN 200 AND 400 J/KG OF ML CAPE SOME ISOLATED THUNDERSTORMS SHOULD ALSO DEVELOP. AS TEMPERATURES ALOFT COOL WITH THE PASSAGE OF THE UPPER LEVEL TROUGH...THE FREEZING LEVEL WILL ALSO COME DOWN AND IF ANY OF THE THUNDERSTORMS CAN DEVELOP A GOOD CORE ALOFT...SOME HAIL WILL BE POSSIBLE. AS THE SYSTEM THEN MOVES AWAY FROM THE AREA TONIGHT AND WITH THE LOSS OF THE CAPE...EXPECT THE ACTIVITY TO DIE DOWN DURING THE EVENING WITH THE SHOWERS ENDING COMPLETELY AFTER MIDNIGHT. .LONG TERM...(SUNDAY THROUGH FRIDAY) ISSUED AT 321 AM CDT SAT JUN 1 2013 RIDGING ALOFT WILL BRIEFLY BUILD OVER THE UPPER MIDWEST FOR SUNDAY AND MONDAY AND WITH HIGH PRESSURE AT THE SURFACE...A COUPLE OF DRY DAYS ARE ANTICIPATED. THIS RIDGING THEN MOVES OFF AS ANOTHER CLOSED UPPER LEVEL LOW APPROACHES FROM THE NORTHWEST. THIS SYSTEM LOOKS TO BE ANOTHER SLOW MOVING SYSTEM AND WILL KEEP RAIN CHANCES IN FOR AN EXTENDED TIME FROM MONDAY NIGHT THROUGH FRIDAY. UNLIKE THE PAST SYSTEM...THIS ONE IS NOT EXPECTED TO PRODUCE NEARLY AS MUCH HEAVY RAIN. THE 01.00Z GFS INDICATES PRECIPITABLE WATERS WITH THIS SYSTEM WILL PRIMARILY BE IN THE 1 TO 1.25 INCH RANGE INSTEAD OF 1.5 INCHES OR HIGHER AS WITH THE RECENT SYSTEM. ALSO...THE 01.00Z ECMWF SUGGESTS THAT AS THE SHORT WAVE TROUGHS ROTATE AROUND THE UPPER LEVEL LOW...THE BULK OF THE FORCING WILL ACTUALLY BE NORTH OF THE AREA FROM CENTRAL MINNESOTA AND NORTHWEST WISCONSIN ON TO THE NORTH. ALSO NOT EXPECTING A LOT OF THUNDER FROM THIS SYSTEM. NEITHER THE ECMWF OR GFS SHOW HARDLY ANY CAPE OVER THE AREA FROM THIS SYSTEM AND THUS CUT THE THUNDER PROBABILITIES BACK TO JUST HAVE ISOLATED AT BEST. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY MORNING) ISSUED AT 647 AM CDT SAT JUN 1 2013 AN UPPER LEVEL LOW WILL MOVE EAST THROUGH THE AREA THIS AFTERNOON AND TONIGHT. AS THIS OCCURS...A BROKEN DECK OF 3-5K DECK OF CLOUDS WILL DEVELOP BY LATE THIS MORNING AND CONTINUE INTO THE AFTERNOON AT BOTH TAF SITES. IN ADDITION TO THE LOWER CEILINGS...THERE WILL BE ENOUGH INSTABILITY FOR SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS. AS THE LOW MOVES EAST OF THE AREA TONIGHT... CEILINGS WILL BECOME MVFR AND THE WINDS WILL JUST OUT OF THE NORTHWEST AT 20 TO 30 MPH. && .HYDROLOGY... ISSUED AT 321 AM CDT SAT JUN 1 2013 THE RAINS FROM FRIDAY EVENING HAVE CAUSED SOME RESPONSE ON SOME AREA RIVERS. RISES HAVE BEEN OCCURRING ON THE WHITEWATER RIVER...CEDAR RIVER IN OSAGE AND THE ROOT RIVER. ENOUGH RAIN FELL ACROSS PARTS OF SOUTHEAST MINNESOTA AND NORTHEAST IOWA FOR ADDITIONAL WITHIN BANK RISES TO OCCUR. EARLIER RAINS ARE STILL EXPECTED TO PUSH PARTS OF THE MISSISSIPPI...BLACK...TREMPEALEAU AND UPPER IOWA RIVERS NEAR OR OVER FLOOD STAGE.
