Area forecast discussion, May 29, 10:38 PM CDT, 5 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 1038 PM CDT FRI MAY 29 2015 UPDATED AVIATION PORTION FOR 06Z TAF ISSUANCE .SHORT TERM...TONIGHT AND SATURDAY ISSUED AT 227 PM CDT FRI MAY 29 2015 THE LATEST RAP ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW A STRONG COLD FRONT MOVING ACROSS NORTHWEST WISCONSIN EARLY THIS AFTERNOON. SCATTERED SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP AHEAD OF THE FRONT WITH HELP FROM WEAK SHORTWAVES...ONE OVER SOUTHWEST WISCONSIN...AND ANOTHER OVER SOUTHERN MINNESOTA. AS THE WAVE OVER SOUTHEAST WISCONSIN LIFTS NORTHEAST...SCATTERED STORMS SHOULD SPREAD ACROSS THE FOX VALLEY AND LAKE SHORE AREAS WHERE ML CAPES ARE BUILDING TO GREATER THAN 400 J/KG. SHOWERS AND A FEW THUNDERSTORMS WILL ALSO BECOME MORE WIDESPREAD OVER N-C WISCONSIN AHEAD OF THE FRONT THIS AFTERNOON. GUSTY WINDS AND SMALL HAIL WILL BE POSSIBLE WITHIN ANY STORMS...ALONG WITH A POTENTIAL QUICK INCH OF RAIN. WITH A JUICY AIRMASS IN PLACE...PRECIP TRENDS AND AMOUNTS ARE THE MAIN FORECAST CONCERNS AS THE FRONT SLOWLY MOVES ACROSS THE REGION. TONIGHT...THE STRONG COLD FRONT WILL MOVE SOUTHEAST ACROSS CENTRAL AND NORTHEAST WISCONSIN DURING THE EVENING. AHEAD OF THE FRONT...SCATTERED SHOWERS AND THUNDERSTORMS WILL BE OCCURRING IN AN AREA OF DIMINISHING INSTABILITY. IN ADDITION...THERE WILL BE A MINIMUM OF SHEAR RIGHT AHEAD OF THE FRONT. SO POTENTIAL FOR ANY SEVERE WEATHER REMAINS LOW...BUT GUSTY WINDS TO 40 MPH AND SMALL HAIL LOOKS REASONABLE WITHIN ANY THUNDERSTORMS. BEHIND THE FRONT...STRONG MID-LEVEL FGEN COMBINED WITH UPPER DIVERGENCE IN THE RIGHT REAR QUAD OF AN UPPER JET...AND PWATS IN EXCESS OF 1.50 WILL LEAD TO A BAND OF MODERATE TO HEAVY RAIN SLOWLY MOVING ACROSS THE FORECAST AREA. THE SLOW MOVEMENT OF THE RAIN WITH SOME INTERACTION FROM DAYTIME INSTABILITY LEADS ME TO THINK THE HIGHEST RAINFALL TOTALS WILL BE ACROSS NORTH-CENTRAL WISCONSIN WHERE A WIDESPREAD INCH...LOCALLY UP TO 2 INCHES WITHIN THUNDERSTORMS...COULD FALL. ELSEWHERE...A WIDESPREAD HALF INCH TO INCH LOOKS REASONABLE. NORTH WINDS WILL BECOME GUSTY LATE BEHIND THE FRONT AS COLDER AIR RUSHES IN. LOWS RANGING FROM THE LOWER 40S NORTH TO MID 50S SOUTH. SATURDAY...THOUGH THE FRONT WILL BE EXITING THE REGION BY THE START OF SATURDAY MORNING...RIGHT REAR QUAD OF THE UPPER JET AND MID-LEVEL FGEN WILL BE HANGING OVER EASTERN WISCONSIN. HAVE INCREASED PRECIP CHANCES THERE FOR THE MORNING. MODELS ARE ALSO SLOWER EXITING PRECIP IN THE AFTERNOON...AND HAVE KEPT A SMALL CHANCE OVER EAST- CENTRAL WISCONSIN THROUGH 21Z. AS A COLD CANADIAN AIRMASS BUILDS INTO THE REGION...TEMPERATURES WILL BE SIGNIFICANTLY COOLER THAN TODAYS READINGS. WITH BLUSTERY CONDITIONS...HIGHS WILL RANGE FROM THE MID 50S NORTH TO LOW 60S SOUTH. .LONG TERM...SATURDAY NIGHT THROUGH FRIDAY ISSUED AT 227 PM CDT FRI MAY 29 2015 THE POTENTIAL FROST AND FREEZE HEADLINES WILL BE THE PRIMARY ISSUE THIS WEEKEND AS A VERY COOL DRY HIGH PRESSURE SYSTEM WILL DRIFT OVER THE GREAT LAKES REGION IN THE WAKE OF A STRONG COLD FRONT. NEXT PCPN CHANCES FOR NEXT WEEK WILL BE THE NEXT ISSUE AS TEMPERATURES GRADUALLY WARM. THE RIDGE AXIS OF THE A CANADIAN HIGH PRESSURE SYSTEM IS PROGGED TO BE OVER NORTHERN WISCONSIN DURING THE LATE SATURDAY NIGHT HOURS. THE LIGHT WINDS...CLEAR SKIES...DRY AIR AND H850 TEMPS LESS THAN +2 C PROVIDE A LIKELY SCENARIO OF FROST OR FREEZING TEMPERATURES. ANTICIPATE A HEADLINE WILL BE NEEDED IN THE NEXT 24 HOURS AFTER DEALING WITH THE STRONG COLD FRONT AND CONVECTION. AIR MASS MAY STILL SUPPORT SOME FROST OVER THE FAR NORTHEAST SUNDAY NIGHT BUT NOT AS WIDESPREAD. TEMPERATURES WILL GRADUALLY WARM FOR THE START OF THE NEW WEEK AS AN UPPER RIDGE SETTLES OVER THE GREAT LAKES REGION. THE CANADIAN SURFACE HIGH WILL CONTINUE TO RIDGE INTO THE REGION WHILE THE RETURN WARM AIR ADVECTION FLOW AND CHANCES OF CONVECTION IS PRIMARILY CONFINED TO THE NORTHERN PLAINS IN THE SOUTHWEST FLOW OF A BROAD UPPER TROUGH OVER THE WESTERN STATES. SOME DEBRIS CLOUDS FROM THIS NORTHERN PLAINS CONVECTION MAY BE ABLE TO DRIFT INTO NORTHERN WISCONSIN MONDAY AND TUESDAY TO AFFECT TEMPERATURES. CONVECTION MAY BEGIN TO SPREAD INTO AT LEAST THE NORTHWEST PORTION OF WISCONSIN ON WEDNESDAY AND THURSDAY WITH THE UPPER RIDGE PROGGED TO SHIFT A BIT MORE EAST. RETURN FLOW 850 WARM AIR ADVECTION CONTINUES TO INCREASE OVER THE NORTHERN PLAINS AS WELL AS INTO THE FAR WESTERN GREAT LAKES REGION. EASTERN SECTIONS MAY CONTINUE TO BE PROTECTED BY THE DEPARTING HIGH PRESSURE SYSTEM SO HIGH PCPN CHANCES WILL BE CONFINED OVER THE NORTHWEST. PROGS IN SOME AGREEMENT WITH THE UPPER RIDGE SUBSIDING AND A RETURN TO A SOUTHWEST FLOW ALOFT AND PCPN CHANCES SPREADING EASTWARD LATE NEXT WEEK. && .AVIATION...FOR 06Z TAF ISSUANCE ISSUED AT 1037 PM CDT FRI MAY 29 2015 LIGHT RAIN AND INSTRUMENT FLIGHT RULES CONDITIONS EXPECTED TONIGHT THROUGH AROUND 15Z SATURDAY.

AN ANTICIPATED WIDESPREAD 1 INCH RAINFALL THROUGH SATURDAY MORNING WILL REVERSE THAT TREND WITH SOME RIVERS LIKELY RISING TO NEAR FS AND PERHAPS A FEW EXCEEDING INTO THE MINOR FS LEVELS BY SATURDAY MORNING. LOCALLY HIGHER 2 INCHES AMOUNTS POSSIBLE WITH THUNDERSTORMS. ISOLATED TO SCATTERED STORMS WITH LOCALLY HEAVY RAINFALL ANTICIPATED AHEAD OF THE COLD FRONT THROUGH THIS EVENING. A MORE WIDESPREAD 1 INCH RAINFALL IN THE WAKE OF THE COLD FRONT OR POST FRONTAL REGION...WITH LOCALLY HIGHER AMOUNTS OF 2 INCHES DUE TO EMBEDDED STORMS. TDH. && .GRB WATCHES/WARNINGS/ADVISORIES...
