NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 6, 6:00 PM EST, 1 hour 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 700 PM EDT MON JUN 6 2011 .SYNOPSIS.../ISSUED AT 351 PM/ A WARM FRONT WILL SLOWLY LIFT NORTH INTO NORTHERN MICHIGAN TONIGHT. THIS FRONT WILL USHER IN INCREASING HEAT AND HUMIDITY THROUGH MIDWEEK...AS WELL AS PROVIDE SEVERAL CHANCES FOR SHOWERS AND THUNDERSTORMS. THE THREAT FOR PRECIPITATION WILL END ON THURSDAY AS A COLD FRONT SWEEPS THROUGH THE REGION...USHERING IN COOLER AND DRIER WEATHER BY THE END OF THE WORK WEEK. NS && .SHORT TERM.../ISSUED AT 351 PM/...TONIGHT THE NORTHERN MICHIGAN CONVECTIVE COMPLEXITY CONTINUES THROUGH THE OVERNIGHT AS DIFFUSE FRONTAL FEATURES INTERACT WITH AN INCREASINGLY MOIST AIR MASS. LEADING EDGE OF DEEPER MOISTURE EASILY IDENTIFIED (SEE MID AND UPPER 60 DEW POINTS BACK ACROSS WISCONSIN) THIS AFTERNOON AS NORTHWEST TO SOUTHEAST BROKEN LINE OF SHOWER AND THUNDERSTORMS CUTTING ACROSS LAKE MICHIGAN AND SOUTHWEST LOWER MICHIGAN. SURGE OF LOW LEVEL THETA-E WILL CONTINUE TO ADVANCE NORTHEAST ACROSS THE AREA THIS EVENING...WITH PWAT VALUES SURGING ABOVE ONE INCH. DEEPER MOISTURE SET TO INTERACT WITH SLOW NORTHWARD MOVING SOUTHWEST LAKES WARM FRONT AND DIFFUSE (AND FURTHER WEAKENING) COLD FRONT/TROUGH AXIS DROPPING SOUTHEAST OUT OF WESTERN ONTARIO AND MINNESOTA. EXPECT INITIAL MOISTURE SURGE TO CONTINUE TO DEVELOP SOME SCATTERED SHOWER AND STORM ACTIVITY THROUGH LATER THIS AFTERNOON...WITH AN INCREASE IN COVERAGE EARLY THIS EVENING AS ABOVE FEATURES AND WEAKISH LOW LEVEL JET AXIS COMBINE FORCES. AS ALWAYS WITH CONVECTION...CONFIDENCE IN JUST HOW THINGS WILL UNFOLD REMAINS EXCEEDINGLY LOW...AND WILL REFRAIN FROM GOING LIKELY WORDING DESPITE MOST GUIDANCE SUGGESTING OTHERWISE. THAT SAID...BEST INSTABILITY AXIS REMAINS ALONG AND SOUTH OF THE MIGHTY MAC THIS EVENING...SO FORECAST WILL BE TAILORED IN THIS DIRECTION. AS FOR SEVERE POTENTIAL...NEARLY ALL OF NORTHERN MICHIGAN REMAINS HIGHLIGHTED UNDER A SLIGHT RISK IN LATEST RENDITION OF THE STORM PREDICTION CENTERS CONVECTIVE OUTLOOK. WHILE MID LEVEL WIND FIELDS NOT OVERLY IMPRESSIVE (BEST MID LEVEL JET CORE REMAINS NORTH)...ML CAPES NEARING 2K J/KG AND DISTINCT POSSIBILITY OF CONGEALING COLD POOLS FROM ANTICIPATED UPSTREAM THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON MAY DRIVE AN MCS ACROSS OUR AREA THIS EVENING... WITH LARGE HAIL AND DAMAGING WINDS A POSSIBILITY. CONFIDENCE IN THIS HAPPENING REMAINS VERY LOW...SO WILL NOT EXPLICITLY MENTION SEVERE WEATHER IN THE TEXT OF THE FORECAST. OTHERWISE...A RATHER MILD NIGHT IS EXPECTED...WITH READINGS IN THE 50S AND 60S. MSB && .LONG TERM.../ISSUED AT 351 PM/...TUESDAY AND BEYOND TUESDAY...SUBTLE WARM FRONTAL SIGNATURE LIFTS INTO LOWER MICHIGAN AS MID/UPPER LEVEL RIDGE AXES BUILD ACROSS THE UPPER GREAT LAKES. STEEP MID LEVEL LAPSE RATES ASSOCIATED WITH ELEVATED MIXED LAYER ALSO OVERSPREAD THE FORECAST AREA. GUIDANCE HAVING SOME SERIOUS ISSUES WITH BOUNDARY LAYER MOISTURE DEPICTION HOWEVER...STARTING WITH GFS MID 70S DEW POINTS INTO TVC/CAD THIS EVENING (ALONG WITH A STRATUS DECK)...NAM-WRF MID 70S DEW POINTS TUESDAY AFTERNOON AND RESULTANT 5000+J/KG UNCAPPED MLCAPE VALUES ALSO LOOK...WE'LL CALL IT UNREALISTIC (AND TYPICAL NAM-WRF MISBEHAVIOR). GFS ON THE OTHER HAND LOOKS TOO DRY IN SPOTS (AND TOO COOL WHERE IT FAILS TO MIX OUT ITS DEPICTED STRATUS DECK...SUCH AS AT CAD) AND THUS HAS A FAIR BIT MORE CAPPING. SUSPECT REALITY AS USUAL LIES SOMEWHERE IN THE MIDDLE...MODIFYING FORECAST SOUNDINGS FOR A DEW POINT PROFILE EVEN A COUPLE DEGREES ABOVE THE GFS PRETTY MUCH ELIMINATES THE CINH WITH MLCAPE VALUES ABOVE 2500J/KG FOR A 87/66 PARCEL OVER NORTHERN LOWER. SO AFTER WHAT WILL PROBABLY BE A DRY MORNING...COULD SIMPLY SEE SOME POP-UP CONVECTION WITH DAYTIME HEATING WITH LAKE BREEZES SERVING TO FOCUS SOME CONVECTIVE POTENTIAL. LOW CHANCE POPS WILL BE USED TO COVER THIS...TOO UNCERTAIN TO GO ANYTHING HIGHER. CONTINUED WARM AND CONSIDERABLY MORE HUMID TUESDAY AFTERNOON. ACTIVITY SHOULD WANE DURING THE EVENING...WITH POSSIBLY ANOTHER ROUND MOVING IN OVERNIGHT AS THUNDERSTORMS THAT DEVELOP UPSTREAM AND ROLL EAST ALONG VEERING LOW LEVEL JET. WEDNESDAY...SHORT WAVE ENERGY LIFTING NORTHEAST OUT OF THE NORTHERN PLAINS AND INTO NORTHWEST ONTARIO WEDNESDAY...ASSOCIATED SURFACE LOW TRACKS EAST ALONG A WARM FRONT FROM NORTHERN MINNESOTA INTO LAKE SUPERIOR. THIS ALSO DRAGS A COLD FRONT INTO WESTERN UPPER/WISCONSIN DURING THE AFTERNOON. SO POTENTIALLY TWO CHANCES FOR PRECIPITATION WEDNESDAY...ONE DURING THE MORNING WITH WHATEVER REMAINS FROM OVERNIGHT CONVECTION (MAINLY EASTERN UPPER/NORTHWEST LOWER)...THEN POSSIBLY ANOTHER ROUND HEADING INTO WEDNESDAY EVENING AS COLD FRONT CROSSES EASTERN WISCONSIN (MORE WIDESPREAD PROBABILITIES FOR PRECIPITATION). THURSDAY...COLD FRONT WILL BE DROPPING THROUGH LOWER MICHIGAN DURING THE DAY THURSDAY...WITH A PUSH OF COOLER/DRIER AIR INTO NORTHERN MICHIGAN. THIS WILL (FINALLY) DIMINISH THE THREAT FOR SHOWERS/ THUNDERSTORMS...MAY STILL BE SOME RAIN CHANCE DURING THE MORNING THURSDAY AT LEAST ACROSS NORTHERN LOWER MICHIGAN BUT WILL GO DRY ALL AREAS FOR NOW AND ADJUST FOR FRONTAL TIMING WITH LATER FORECASTS. EXTENDED FORECAST (FRIDAY THROUGH MONDAY)...LARGE SCALE PATTERN HEADING INTO THE EXTENDED PERIODS OF THE FORECAST FEATURE AN EXPANSIVE HEAT RIDGE ACROSS THE SOUTHEAST QUADRANT OF THE CONUS... WITH MORE OF A QUASI-ZONAL MEAN FLOW ACROSS THE NORTHERN TIER OF STATES. ANOTHER DISTURBANCE COMING OUT OF THE WESTERN U.S. WILL CROSS THE PLAINS STATES FRIDAY...AND HEAD TOWARD THE UPPER GREAT LAKES/OHIO VALLEY FOR THE START OF THE WEEKEND. HIGH PRESSURE OVER NORTHERN ONTARIO SHOULD DOMINATE THE WEATHER FOR FRIDAY WITH A COOL NORTHEAST WIND INTO LOWER MICHIGAN. STATIONARY FRONT WILL RUN WEST-EAST ACROSS THE OHIO VALLEY AND WILL BE THE MAIN FOCUS FOR PRECIPITATION FRIDAY...SO ITS NOT IMPOSSIBLE THAT THE NORTHERN FRINGES OF THAT ACTIVITY COULD IMPACT FAR SOUTHERN PORTIONS OF THE FORECAST AREA LATER FRIDAY...BUT MORE LIKELY THAT RAIN CHANCES WILL INCREASE SATURDAY AS UPPER DISTURBANCE HELPS BUCKLE THE FRONT NORTHWARD WHILE TURNING MID/UPPER LEVEL WINDS MORE SOUTHWESTERLY. SO WILL KEEP FRIDAY DRY...THEN INCREASING RAIN CHANCES FOR SATURDAY INTO SATURDAY NIGHT. GOOD BIT OF SPREAD BEYOND SATURDAY REGARDING EVOLUTION OF UPPER LEVEL ENERGY AND RESULTANT SURFACE RESPONSE... CURRENT PREFERENCE IS TO KEEP THE LATTER HALF OF THE WEEKEND DRY (ESSENTIALLY A CONSISTENCY ISSUE)...AND START THE NEW MONDAY FORECAST OUT DRY AS WELL (BOTH MOST CERTAINLY SUBJECT TO CHANGE). EXTENDED TEMPERATURES WON'T BE TOO OUT OF THE ORDINARY...PROBABLY COOLER THAN AVERAGE THROUGH THE FIRST HALF OF THE WEEKEND...THEN BACK CLOSER TO NORMAL FOR SUNDAY/MONDAY. JPB && .MARINE.../ISSUED AT 351 PM/ WEAK PRESSURE GRADIENT FORECAST TO BE IN PLACE TUESDAY AS A WARM FRONT LIFT INTO THE UPPER GREAT LAKES...WHICH MEANS LAKE BREEZES AND LOCAL PRESSURE EFFECTS WILL DOMINATE THE NEARSHORE WINDS TUESDAY AFTERNOON. SYNOPTIC SOUTHWEST FLOW WILL PICK UP TUESDAY NIGHT AND CONTINUE INTO WEDNESDAY. COULD BE SOME BORDERLINE SMALL CRAFT CONDITIONS ESPECIALLY ON THE LAKE MICHIGAN SIDE OF THE HOUSE. COLD FRONT COMES THROUGH EARLY THURSDAY MORNING...WHICH WILL SHIFT WINDS AROUND TO THE NORTHWEST. INCREASING DEW POINTS WILL ALSO LEAD TO SOME FOG DEVELOPING AS WELL (AGAIN MOST PREVALENT WITHIN LAKE MICHIGAN NEARSHORE ZONES.) JPB && .AVIATION.../ISSUED AT 700 PM/...VALID FOR 00Z TAFS ASIDE FROM SOME LATE NIGHT/EARLY MORNING FOG (MVFR VSBYS)...EXPECT MAINLY VFR CONDITIONS THRU THE 24 HR TAF PERIOD. SCATTERED SHOWERS AND THUNDERSTORMS WILL IMPACT MAINLY PLN AND APN THIS EVENING...WITH LESSER CHANCES OF PRECIP FOR TVC THROUGH MIDNIGHT. PRECIP SHOULD COME TO AN END BY 06Z WITH LOSS OF DIURNALLY ENHANCED INSTABILITY. PRECIP CHANCES WILL BE RENEWED BY TUESDAY AFTERNOON...BUT TIMING AND AREAL COVERAGE IS STILL IN QUESTION. WILL LEAVE PRECIP OUT OF THE TUESDAY AFTERNOON TAF FOR NOW...BUT WILL UPDATE/AMEND AS NEEDED. && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LH...NONE. LM...NONE. LS...NONE. &&
