AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 248 PM CDT WED JUN 23 2010 .SHORT TERM...THROUGH FRIDAY NIGHT MAIN FORECAST CONCERN IS WITH THE RAIN CHANCES TONIGHT AND AGAIN FOR FRIDAY AND FRIDAY NIGHT. SURFACE ANALYSIS THIS AFTERNOON SHOWS THE COLD FRONT WAS OVER FAR SOUTHERN WISCONSIN AND THEN SOUTHWEST ACROSS EASTERN IOWA INTO KANSAS. A SECONDARY FRONT EXTENDS FROM NORTH CENTRAL WISCONSIN INTO SOUTHERN MINNESOTA. THE UPPER LEVEL LOW AND TROUGH OVER MINNESOTA IS MAKING STEADY EASTWARD PROGRESS TODAY. THE SHORT WAVE TROUGH ASSOCIATED WITH THIS SYSTEM IS HELPING TO SPAWN SOME SHOWERS BEHIND THE SECONDARY FRONT ACROSS NORTHERN WISCONSIN INTO CENTRAL MINNESOTA. AS THE UPPER LEVEL SYSTEM AND THE FRONT PROGRESS EAST ACROSS THE REGION THIS EVENING THERE WILL BE A CHANCE FOR SOME OF THESE SHOWERS TO HIT PORTIONS OF THE AREA THIS EVENING. THE INSTABILITY BEHIND THE FRONT IS EXTREMELY LIMITED AND ONLY ABOUT 500 J/KG OF MU CAPE. OUT AHEAD OF THE FRONT THERE IS ABOUT 1000 J/KG OF MU CAPE AND IF THE SHOWERS CAN TAP INTO THIS THEY MAY BECOME A LITTLE MORE WIDESPREAD AND DEVELOP SOME THUNDER. THE 23.12Z NAM SUGGESTS THERE IS THE POTENTIAL ACROSS MUCH OF WISCONSIN DURING THE EVENING HOURS FOR SOME SHOWERS WHILE THE 23.16Z RAPID UPDATE RUC TAKES THE CURRENT ACTIVITY AND MOVES IT EAST INTO CENTRAL WISCONSIN ACROSS THE NORTHERN SECTIONS. THE 23.12Z SPCWRF IS A HYBRID OF THESE TWO SOLUTIONS IN ALSO TAKING THE CURRENT ACTIVITY EAST INTO WISCONSIN WHILE ALSO DEVELOPING A LITTLE MORE FARTHER SOUTH. HAVE OPTED TO ADD IN SOME 20 TO 30 PERCENT RAIN CHANCES FOR AREAS ALONG AND EAST OF THE MISSISSIPPI RIVER FOR THE EVENING. HIGH PRESSURE WILL BUILD IN OVER THE AREA LATE TONIGHT AND REMAIN THROUGH THURSDAY NIGHT. AS THE HIGH PULLS OFF TO THE EAST A WARM FRONT IS EXPECTED TO DEVELOP ACROSS CENTRAL MINNESOTA INTO NORTHERN WISCONSIN AND THEN SINK SOUTH INTO THE AREA FRIDAY NIGHT. A COUPLE OF SHORT WAVE TROUGHS COMING OUT OF AN UPPER LEVEL SYSTEM OVER THE PACIFIC NORTHWEST COAST WILL INTERACT WITH THE FRONT. WEAK TO MODERATE FRONTOGENESIS IS EXPECTED TO BE ASSOCIATED WITH THE FRONT IN THE 1000-500 MB LAYER. AS THE WARM AIR ADVECTION DEVELOPS ON THE BACK SIDE OF THE SURFACE HIGH UP TO 6 UBAR/S OF UP GLIDE SHOULD OCCUR ON THE 305K ISENTROPIC SURFACE ALONG WITH GOOD MOISTURE TRANSPORT INTO THE BAROCLINIC ZONE. ADDED 20 PERCENT RAIN CHANCES ACROSS THE FAR NORTH FOR FRIDAY AFTERNOON AHEAD OF THE FRONT AND THEN MAINTAINED THE 30 TO 50 PERCENT CHANCES FROM SOUTH TO NORTH FOR FRIDAY NIGHT. IT APPEARS THE BEST FORCING WILL OCCUR FRIDAY NIGHT WITH A POSSIBLE MCS FORMING. CONFIDENCE ON THE PLACEMENT OF THIS MCS IS NOT HIGH ENOUGH THIS FAR OUT TO TAKE THE RAIN CHANCES PAST 50 PERCENT. .LONG TERM...SATURDAY THROUGH WEDNESDAY MEDIUM RANGE MODELS SHOW VERY SIMILAR SOLUTIONS TODAY WITH ONLY SOME MINOR TIMING DIFFERENCES. THE OVERALL UPPER LEVEL FLOW LOOKS TO BE DOMINATED WITH EAST AND WEST COAST TROUGHS WITH A SUB TROPICAL RIDGE OVER THE SOUTHERN CONUS. IT APPEARS THAT A SHORT WAVE TROUGH WILL EJECT OUT OF THE WESTERN TROUGH AND WORK ACROSS THE NORTHERN PART OF THE COUNTRY FOR LATE IN THE WEEK INTO THE WEEKEND. ONCE THIS SYSTEM PASSES THE RIDGE WILL AMPLIFY OVER THE ROCKIES SETTING UP WHAT LOOKS TO BE A QUIET NORTHWEST FLOW OVER THE GREAT LAKES REGION. AT THE SURFACE...A FRONT LOOKS TO STRETCH OUT EAST/WEST FROM THE LOWER GREAT LAKES TO AN AREA OF LOW PRESSURE OVER SOUTH DAKOTA OR NEBRASKA. THE MODELS ARE SUGGESTING THE POSSIBILITY OF TWO CONVECTIVE SYSTEMS MOVING ALONG THE FRONT WITH THE REMAINS OF THE FIRST EXITING THE AREA SATURDAY MORNING. THE SECOND SYSTEM IS THEN EXPECTED MOVE ALONG THE FRONT AND OVER THE AREA FOR SATURDAY NIGHT INTO SUNDAY MORNING. PLAN TO HAVE 30 TO 50 PERCENT RAIN CHANCES FROM SATURDAY THROUGH SUNDAY NIGHT TO HANDLE THESE POSSIBLE CONVECTIVE SYSTEMS. FOR MONDAY THROUGH THE REMAINDER OF THE PERIOD...HIGH PRESSURE SHOULD BE OVER THE AREA. && .AVIATION... A COLD FRONT WILL MOVE SOUTHEAST THROUGH THE AREA THIS AFTERNOON. WHILE THE MAJORITY OF THE PRECIPITATION IS CURRENTLY POST FRONT... SOME SCATTERED SHOWERS AND THUNDERSTORMS SHOULD DEVELOP ALONG AND AHEAD OF THE FRONT AS THE ATMOSPHERE DESTABILIZES. A FEW OF THESE THUNDERSTORMS MAY BECOME SEVERE BETWEEN 23.19Z AND 24.00Z. IF SEVERE WEATHER HAPPENS TO DEVELOP...THE MAIN THREATS WOULD BE DAMAGING WINDS AND LARGE HAIL. CEILINGS WILL LIKELY DROP IN THE 1500 TO 2500 FOOT RANGE AFTER THE FRONTAL PASSAGE AND REMAIN THAT WAY THROUGH THE EVENING....AND THEN SKIES WILL GRADUALLY CLEAR OVERNIGHT AND REMAIN THAT WAY THROUGH THURSDAY. && .ARX WATCHES/WARNINGS/ADVISORIES...
