NWS Gaylord, MI wrote its last area forecast discussion before the first event at May 25, 1:50 PM EST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 250 PM EDT THU MAY 25 2006 .DISCUSSION...THURSDAY AFTERNOON...VERTICALLY STACKED SURFACE/UPPER LOWS WERE CENTERED OVER E CENTRAL WI...AND WERE ROLLING E/SE. THE COMBINATION OF DIURNAL SURFACE HEATING (SOMEWHAT LIMITED BY CLOUD COVER BUT STILL PUSHING TEMPERATURES INTO THE 70S AT SOME LOCATIONS) AND SUBTLE COOLING ALOFT (12Z 500 MB TEMPS RANGED FROM -10.5 AT APX TO -12C CLOSER TO THE UPPER COLD POOL AT GRB)...ALONG WITH SURFACE DEWPOINTS CREEPING INTO THE LOWER 60S ACROSS S/SW COUNTIES...WAS SUPPORTING EXPANDING DEVELOPMENT OF SHOWERS/THUNDERSTORMS ACROSS SOUTHERN COUNTIES...WITH CONVECTION SPREADING NORTH INTO NORTHERN LOWER MICHIGAN. PRIMARY FORECAST CONCERNS INCLUDE SEVERE POTENTIAL LATE THIS AFTERNOON/THIS EVENING...AND POPS LATE THIS AFTERNOON THROUGH FRIDAY. AROUND MID AFTERNOON...LAPS DEPICTED MAXIMUM CAPES AROUND 800 J/KG PUSHING INTO W/SW COUNTIES OF THE FORECAST AREA...TAPERING TO 200 J/KG OF LESS ACROSS THE FAR N/NE...WHERE THE STABILIZING INFLUENCE OF THE LAKE HURON BOUNDARY LAYER WAS EVIDENT. MODIFIED AFTERNOON/EVENING MODEL SOUNDINGS FOR TEMPS 75-80F AND DEWPOINTS 60-65 PUSH CAPES TO AROUND 1000 J/KG...BUT GIVEN THE ONGOING TREND TOWARD EXPANDING CLOUD COVER/PRECIP COVERAGE...THIS PROBABLY OVERESTIMATES THE DEGREE OF SURFACE BASED INSTABILITY. THUS...PULSE MODE PRECIPITATION...WITHIN AN ENVIRONMENT FEATURING 0-6 KM BULK SHEAR 5-15 KNOTS...WILL BE HARD PRESSED TO PRODUCE SEVERE WEATHER THROUGH THIS EVENING...AND WOULD EXPECT NOTHING MORE THAN AN ISOLATED CELL BRIEFLY PRODUCING MARGINALLY SEVERE HAIL (WET BULB ZERO HEIGHTS 10.5 KFT) AND/OR DAMAGING WIND GUSTS (DUE TO PRECIP LOADING). GIVEN PWATS 1.2-1.4/K INDICES AROUND 35 AND RELATIVELY SLOW N/NW MOVEMENT (NO MORE THAN 10 MPH) OF THUNDERSTORMS...LOCALLY HEAVY RAINFALL IS CERTAINLY POSSIBLE. OTHERWISE...THE COMBINATION OF RADAR/SATELLITE TRENDS...DIURNAL EXPANSION OF CONVECTION AND 12Z GFS/NAM GUIDANCE JUSTIFIES AT LEAST LIKELY POPS (WILL MAKE FINAL DECISIONS REGARDING POPS...POSSIBLY INCLUDING AREAS OF CATEGORICAL POPS...CLOSER TO ISSUANCE TIME) UNTIL AROUND MIDNIGHT ACROSS NORTHERN LOWER MI. ACROSS THE EASTERN UP...RESIDUAL DRIER AIR (DEWPOINTS IN THE 50S COMMON) AND LOCATION FARTHEST REMOVED FROM THE UPPER LOW...WILL LOWER EVENING POPS FROM LIKELY TO CHANCE TO ACCOUNT FOR REDUCED PRECIP COVERAGE...MAINLY SUPPORTED BY A BAND OF 500-200 MB DEFORMATION ON THE NORTHERN PERIPHERY OF THE UPPER LOW THAT WILL SETTLE SLOWLY S/SE TONIGHT. AFTER MIDNIGHT...DIURNAL CONTRACTION OF CONVECTION SHOULD TRANSLATE TO DECREASING PRECIP COVERAGE ACROSS MUCH OF NORTHERN LOWER MICHIGAN...ALTHOUGH MORE FREQUENT SHOWERS WILL PERSIST LONGEST ACROSS THE S/SE...CLOSEST TO THE SURFACE LOW. MEANWHILE...DEWPOINTS IN THE 50S/60S FLOWING OVER THE GREAT LAKES FEATURING SURFACE WATER TEMPERATURES IN THE 30S/40S WILL CONTINUE TO SUPPORT PATCHY MARINE STRATUS/FOG...AND STRATUS/FOG SHOULD BECOME MORE COMMON OVER LAND AREAS OVERNIGHT INTO FRIDAY MORNING...ESPECIALLY WHERE RAIN FALLS. FRIDAY...THE UPPER LOW AND ASSOCIATED SHIELD OF ENHANCED MOISTURE WILL RETREAT SLOWLY E/SE...AND POP TRENDS WILL FOLLOW...FADING FROM N/NW TO S/SE. HOWEVER...THERE REMAINS SUFFICIENT MOISTURE... INSTABILITY (SURFACE BASED CAPES 200-500 J/KG) AND 500-200 MB DEFORMATION TO JUSTIFY CHANCE POPS ACROSS E/SE COUNTIES THROUGH FRIDAY AFTERNOON...AND DID NOT ADJUST THE PREVIOUS FORECAST. HOWEVER...GIVEN SLIGHT MODEL DIFFERENCES REGARDING THE EXIT OF DEEPER MOISTURE (GFS FASTER THAN NAM)...ADJUSTMENTS TO TIMING/COVERAGE OF AFTERNOON POPS MAY BE NEEDED IN LATER FORECASTS. IF THE GFS VERIFIES...MOST/ALL SHOWERS MAY END BY EARLY TO MID AFTERNOON FRIDAY. SATURDAY...THE TRANSITION TO A PERIOD OF UNSEASONABLY WARM CONDITIONS WILL BE WELL UNDERWAY AS RIDGING AT THE SURFACE AND ALOFT BUILD INTO THE REGION...WITH HIGHS 75-80F COMMON. THEN...AS THE UPPER RIDGE BECOMES ESTABLISHED ACROSS THE EASTERN US AND THE GREAT LAKES...AND PUSHING 850 MB TEMPS INTO THE 18-20C...SUNDAY AND MEMORIAL DAY SHOULD BE VERY WARM ACROSS THE FORECAST AREA...WITH 80S COMMON AT INLAND LOCATIONS...AND WOULD NOT BE SURPRISED IF A FEW LOCATIONS REACHED 90F MONDAY. MEANWHILE...THE LAST FEW GFS RUNS HAVE CONTINUED TO FORECAST 700 MB TEMPS 6-8C...WITH THE AXIS OF 10-13C 700 MB TEMPS/STRONGEST CAPPING FOCUSED WELL W/NW OF THE REGION. SURFACE COLD FRONT. THUS...CANNOT RULE OUT AN ISOLATED THUNDERSTORM OR TWO DURING THE AFTERNOON/EVENING HOURS SUNDAY OR MONDAY... ESPECIALLY IF MESOSCALE/MARINE RELATED BOUNDARIES CAN DEVELOP...AND/OR IF WEAK 500-200 MB DEFORMATION CAN DEVELOP OVER THE FORECAST AREA...WEST OF THE UPPER RIDGE AXIS. HOWEVER...SINCE THIS SITUATION ONLY SUPPORTS 5-10% POPS...CANNOT YET JUSTIFY A PESSIMISTIC FORECAST WHICH INCLUDES THUNDERSTORMS FOR SUNDAY OR MEMORIAL DAY. MEANWHILE...WITH DEWPOINTS RISING INTO THE 60S AND SURFACE WATER TEMPERATURES STILL HOVERING BELOW 50F EVEN ACROSS NEARSHORE WATERS...THE PATTERN LOOKS FAVORABLE FOR MARINE STRATUS/FOG SUNDAY UNTIL FROPA TUESDAY-WEDNESDAY...AND THAT RAISES THE POSSIBILITY THAT THE COOL/MOIST MARINE LAYER MAY PRODUCE SIGNIFICANTLY LOWER TEMPERATURES AT A FEW LOCATIONS COASTAL LOCATIONS...ESPECIALLY ALONG THE LAKE MICHIGAN SHORELINE OF NORTHERN LOWER MI...AND ACROSS SOUTH FACING COASTAL LOCATIONS ACROSS THE EASTERN UP...OVER THE HOLIDAY WEEKEND. MEDIUM RANGE/MANUAL GUIDANCE HAS STABILIZED REGARDING THE TIMING OF THE COLD FRONT TUESDAY/WEDNESDAY. THIS BOUNDARY SHOULD BE TYPICAL OF A MID-SUMMER COLD FROPA...WITH SLOW E/SE PROGRESS...PRODUCING SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS (WITH PERHAPS OUR BEST SHOT AT ORGANIZED SEVERE WEATHER THUS FAR THIS SEASON)...AND USHERING DRIER AND SOMEWHAT COOLER (HIGHS IN THE 70S) AIR INTO THE REGION WEDNESDAY/THURSDAY. ADJUSTED PREVIOUS FORECASTS TO ACCOUNT FOR TIMING OF FRONT/DIURNAL TRENDS TUESDAY/WEDNESDAY...THEN INTRODUCED A PRECIP FREE FORECAST THURSDAY. ROWLEY && .APX...WATCHES/WARNINGS/ADVISORIES...NONE. &&
