AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 745 AM EDT MON JUL 18 2005 .UPDATE...PER AREA OBSERVATIONS...DROPPED MENTION OF MORNING FOG...AND PER RADAR TRENDS...ADJUSTED FORECASTS FOR CHANCE POPS ANYWHERE UNTIL 2-3 PM...WHEN THUNDERSTORMS SHOULD BECOME MORE NUMEROUS ALONG/EAST OF SURFACE FRONT. ROWLEY && .PREV DISCUSSION...ISSUED 400 AM EDT MON JUL 18 DISCUSSION...SHORTWAVE AND ASSOCIATED COLD FRONT WERE ADVANCING THROUGH THE UPPER MS RIVER VALLEY EARLY THIS MORNING...PRODUCING WIDESPREAD THUNDERSTORMS. IMMEDIATE FORECAST CONCERN CENTERS ON EVOLUTION OF UPSTREAM CONVECTION AND IMPACT ON AREA THIS MORNING. THEN...ATTENTION TURNS TO SEVERE POTENTIAL...AND MARINE WINDS...THIS AFTERNOON INTO THIS EVENING. UPSTREAM CONVECTIVE COMPLEX WILL PUSH AWAY FROM SURFACE BOUNDARY/ 700-500 MB QG FORCING ASSOCIATED WITH SHORTWAVE AND SHOULD THUS WEAKEN/DIMINISH IN INTENSITY THIS MORNING...THUS DO NOT EXPECT ANY SEVERE WEATHER DURING THE AM HOURS. HOWEVER...GIVEN 12Z CAPES (FROM 950 MB) 1000-1500 J/KG AND 950-850 MB MOISTURE ADVECTION ACROSS THE FORECAST AREA...CONVECTION SHOULD HOLD TOGETHER SUFFICIENTLY TO ADVANCE INTO WESTERN COUNTIES LATER THIS MORNING...WHILE ADDITIONAL SHOWERS/THUNDERSTORMS HAVE DEVELOPED IN THE MOISTURE ADVECTION REGIME AHEAD OF THE MAIN COMPLEX...PER LATEST NAM/GFS/RUC GUIDANCE. CURRENT TRENDS FAVOR 60-70% POPS ACROSS THE WESTERN 1/2 OF EASTERN UPPER MICHIGAN AND 30-50% POPS ACROSS MOST OTHER AREAS...EXCEPT FAR E COUNTIES...TO START THIS MORNING. HOWEVER...CONDITIONS ARE CHANGING FAIRLY RAPIDLY...AND TRENDS MAY YET COMPEL HIGHER POPS OVER A LARGER AREA...ESPECIALLY ACROSS THE WEST. AFTER THE INITIAL ROUND OF CONVECTION FADES...UPSTREAM COLD FRONT WILL MOVE INTO AN INCREASINGLY UNSTABLE AIRMASS OVER THE FORECAST AREA THIS AFTERNOON...WHILE 700-500 MB QG FORCING ASSOCIATED WITH THE UPSTREAM SHORTWAVE WILL ACCOMPANY THE SURFACE FRONT...WHILE AN 80-100 KT 300-200 MB JET MAX WILL SWING THROUGH N/W COUNTIES OF THE FORECAST AREA. GIVEN INSTABILITY...LOW LEVEL CONVERGENCE AND SYNOPTIC ASCENT...A NEW ROUND THUNDERSTORMS SHOULD FIRE ALONG THE BOUNDARY DURING THE AFTERNOON...WITH THE FRONT AND CONVECTION ADVANCING E/SE THROUGH EARLY EVENING. IN THE MOST UNSTABLE SCENARIO...0Z NAM SOUNDINGS MODIFIED FOR HIGH TEMPS IN THE MID 80S (EASTERN UP/NW LOWER) TO MID 90S (IN DOWNSLOPE AREAS ACROSS E/SE COUNTIES) AND DEWPOINTS AROUND 70F YIELD CAPES 2000-3000 J/KG...EVEN AS HIGH AS 4000 J/KG E/SE IF HIGHER DEWPOINTS (LOWER 70S) POOL AHEAD OF FRONT AND OFFSET MIXING OF DRIER AIR ALOFT TO THE SURFACE. HOWEVER...MORNING CONVECTION/ASSOCIATED CLOUD DEBRIS MAY LIMIT DESTABILIZATION...ESPECIALLY ACROSS THE N/W. GIVEN THIS SCENARIO AND 0Z NAM TIMING OF THE SURFACE BOUNDARY...THREAT FOR THE PM ROUND OF THUNDERSTORMS SHOULD BE FOCUSED ACROSS THE EASTERN 1/2-2/3 OF NORTHERN LOWER MI. IN FACT...POPS WILL BE LIKELY DURING THE AFTERNOON/EARLY EVENING ACROSS THE E/SE...AND EVEN HIGHER POPS MAY BE NEEDED IF A LINE OF CONVECTION DEVELOPS. THE INSTABILITY...IF POTENTIAL IS FULLY REALIZED...WILL SUPPORT STRONG UPDRAFTS ALONG/AHEAD OF SURFACE FRONT. GIVEN 0-6 KM BULK SHEAR 10-20 KTS TO START...INCREASING TO 20-30 KTS...SUPERCELLS DO NOT APPEAR LIKELY...WITH A MORE LIKELY SCENARIO FAVORING PULSE CONVECTION TO START...WITH A TRANSITION TO ORGANIZED BOWS/SEGMENTS. THE MAIN SEVERE THREAT APPEARS TO BE DAMAGING WINDS THIS AFTERNOON/EARLY EVE...AS 850-500 MB WINDS SHOULD INCREASE TO 30-40 KTS...WHILE 0Z NAM CROSS SECTIONS REVEAL SURFACE-700 DELTA THETA-E AROUND 20C. HOWEVER...CANNOT RULE OUT ISOLATED LARGE HAIL GIVEN DECENT CAPES IN -10C TO -30C LAYER...AND IF DRIER MID LEVEL AIR (700 MB DEWPOINT DEPRESSIONS 5-10C SWINGING AROUND SHORTWAVE)/LOWERING WET BULB ZERO LEVELS (INTO THE 10.5 TO 12 KFT RANGE) SPREAD OVER FRONT. LIMITING FACTORS FOR A WIDESPREAD/SIGNIFICANT SEVERE EVENT INCLUDE AM CONVECTION POSSIBLY LIMITING PM DESTABILIZATION...THE MAIN SHORTWAVE/STRONGEST SYNOPTIC FORCING LIFTING NE THIS AFTERNOON/EVENING...AND ASSOCIATED BAND OF STRONGEST WINDS/DEEP LAYER SHEAR (500 MB WINDS >50 KTS AND 0-6 KM BULK SHEAR > 40 KTS) LAGGING BEHIND SURFACE FRONT POSITION. IN A LESS LIKELY SCENARIO...IF MAXIMUM INSTABILITY IS REALIZED...AND IF SURFACE FRONT SLOWS...ALLOWING STRONGER MID LEVEL WINDS/SHEAR TO CATCH UP WITH CONVECTION...A SIGNIFICANT SEVERE EVENT COULD IMPACT E/SE COUNTIES THIS AFTERNOON/EVENING. MEANWHILE...WAVES ARE ALREADY 3 FEET ON NORTHERN LAKE MICHIGAN... WITHIN THE TIGHTENING SURFACE PRESSURE GRADIENT AHEAD OF THE APPROACHING FRONT. ALSO...THE MIXED LAYER WILL TAP INTO 25-35 KNOT WINDS TODAY...PROMOTING GUSTY WINDS THAT WILL IMPACT DOWNWIND NEARSHORE MARINE ZONES ACROSS THE N/E. THUS...WILL ISSUE SMALL CRAFT ADVISORIES FOR ALL AREAS. IN THE WAKE OF COLD FROPA...COOLER AND DRIER AIR WILL SPREAD INTO THE FORECAST AREA TONIGHT/TUESDAY. AS COLD ADVECTION PUSHES 925 MB TEMPS INTO THE 7-12C RANGE...THE MARINE BOUNDARY LAYER WILL REMAIN WELL MIXED OVERNIGHT INTO TUESDAY MORNING...WITH SMALL CRAFT ADVISORY CONDITIONS LIKELY FOR ALL AREAS. THEN...AS HIGH PRESSURE SETTLES OVER THE REGION TUESDAY...WINDS SHOULD RAPIDLY DIMINISH. FINALLY...AS THE POST FRONTAL SURFACE HIGH PUSHES EAST OF THE REGION WEDNESDAY...STRONG SOUTHERLY FLOW WILL DEVELOP UPSTREAM...BETWEEN THE RETREATING HIGH AND ANOTHER SHORTWAVE/ASSOCIATED COLD FRONT PUSHING INTO THE UPPER MS RIVER VALLEY/WESTERN LAKES. LOW LEVEL CONVERGENCE AND STRONG MOISTURE TRANSPORT (ENHANCED BY 850 MB WINDS INCREASING TO 30-40 KTS PUSHING RIBBON OF 850 MB DEWPOINTS 14C TO 18C)...DESTABILIZATION (CAPES AT LEAST 1000-2000 J/KG AND 700-500 MB LAPSE RATES STEEPENING TO AROUND 7 C/KM) AND SYNOPTIC ASCENT (INCLUDING 700-500 MB QG FORCING) SHOULD PROMOTE UPSTREAM CONVECTION...POSSIBLY ORGANIZED/SEVERE WITHIN 35-45 KNOT 0-6 KM BULK SHEAR REGIME. THIS REGIME WILL EVENTUALLY SLIDE E/SE AND INTO THE FORECAST AREA. WHILE 0Z MODEL TIMING DIFFERS GREATLY CONCERNING THE TIMING OF PRECIP...WITH THE NAM PUSHING CONVECTION INTO THE AREA AS EARLY AS WEDNESDAY AFTERNOON...A COMPROMISE SOLUTION SUGGESTS CHANCE POPS ARE IN ORDER AS EARLY AS WEDNESDAY NIGHT ACROSS THE N/W...AND ALL AREAS THURSDAY. ADJUSTED FORECASTS ACCORDINGLY. NO CHANGES TO FORECASTS BEYOND THURSDAY. ROWLEY && .APX...WATCHES/WARNINGS/ADVISORIES...NONE. &&
