NWS Detroit, MI wrote its last area forecast discussion before the first event at Jul 16, 6:10 AM EST, 4 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 710 AM EDT SAT JUL 16 2005 .AVIATION AND UPDATE... FOG, RAIN, AND THUNDERSTORMS WILL HAMPER AVIATION EFFORTS TODAY, AND ESPECIALLY THIS MORNING AT ALL OF THE TERMINAL SITES IN SE MICHIGAN. SHOWERS AND STORMS ARE NUMEROUS IN THE SAGINAW VALLEY AND THUMB AND SCATTERED AROUND DETROIT. RADAR TRENDS SUGGEST COVERAGE MAY INCREASE SOONER RATHER THAN LATER IN THE DETROIT METRO AREA TO PORT HURON. PLAN TO MONITOR THIS FOR THE NEED OF A PUBLIC FORECAST UPDATE IN THE NEXT HOUR OR TWO. FOG AND HEAVY RAINFALL WILL DROP VISIBILITY INTO THE IFR CATEGORY AT TIMES THIS MORNING, BUT CEILING WILL REMAIN MVFR OR BETTER. VISIBILITY WILL THEN IMPROVE AROUND THE MBS AND FNT SITES AS MORNING PRECIP DIMINISHES, BUT DET AND DTW WILL HAVE TO DEAL WITH THE RAIN LONGER INTO THIS AFTERNOON. A CHANCE OF THUNDERSTORMS WILL LAST INTO TONIGHT OVER ALL OF SE MICHIGAN WITH A CHANCE OF BORDERLINE IFR/MVFR VISIBILITY IN RAIN AND FOG AND SOME LOWER CLOUD CEILINGS AS WARM AND HUMID AIR REMAINS OVER THE REGION. && .PREV DISCUSSION... (ISSUED 320 AM EDT SAT JUL 16 2005) SHORT TERM... TODAY AND TONIGHT SATELLITE IMAGERY SHOWS THE CIRCULATION ASSOCIATED WITH THE UPPER WAVE EXTENDING FROM EASTERN ILLINOIS INTO SW LOWER MICHIGAN EARLY THIS MORNING. THE DEFORMATION ZONE CAN BE SEEN ON BOTH IR AND WV IMAGERY WITH THE NEWEST COLD CLOUD TOPS SHOWING UP ALONG AND EAST OF THE LINE. AT THE SAME TIME, RADAR DATA SHOWS THE BEST COVERAGE OF NEW SHOWER DEVELOPMENT CLOSER TO THE SURFACE REFLECTION OF THE WAVE, ESPECIALLY OVER SE MICHIGAN IN THE VICINITY OF THE 850 TO 700 MB CONVERGENCE ZONE AND ADVANCING THETA-E RIDGE IN MODEL DATA, WHICH IS PRETTY WELL DONE IN THE NAM. EXPECTING THIS TREND TO CONTINUE THROUGH MUCH OF THE DAYLIGHT HOURS OF THE MORNING GRADUALLY MOVING NORTH AND DROPPING SOME HEAVY RAINFALL AT TIMES. THE MOISTURE PROFILE REMAINS TROPICAL IN NATURE WITH 700 MB DEWPOINT RUNNING AROUND 5C, PW NEAR 2 INCHES, AND K-INDEX IN THE UPPER 30S. THINGS GET A LITTLE MORE NEBULOUS THIS AFTERNOON AS CONVECTION WILL TEND TO BECOME MORE SURFACE BASED BUT SURFACE BOUNDARIES WILL NOT BE VERY WELL-DEFINED, OR AT LEAST NOT VERY PREDICTABLE FROM THIS POINT EARLY THIS MORNING. GENERALLY EXPECT LESS DAYTIME HEATING INFLUENCE ON THE SURFACE PRESSURE PATTERN OVER LOWER MICHIGAN COMPARED TO THE LAST COUPLE OF DAYS AND MORE DUE TO THE UPPER WAVE AND THE MORNING PRECIP PATTERN/DIFFERENTIAL HEATING. OUR BEST SHOT AT THIS TIME WILL BE TO THEN FOCUS NEW AFTERNOON DEVELOPMENT BACK OVER SOUTH SECTIONS OF SE MICHIGAN AS THE MORNING ACTIVITY TENDS TO DIMINISH OVER THE SAGINAW VALLEY AND THUMB. THE CYCLE WILL CONTINUE INTO THIS EVENING WITH AFTERNOON STORMS DIMINISHING AND NIGHTTIME ACTIVITY HANGING ON OR EXPANDING IN THE VICINITY OF THE UPPER WAVE INTO THE OVERNIGHT HOURS. THIS WILL MARK THE SAGINAW VALLEY AND THUMB AS HAVING THE BEST CHANCE OF RAIN TOWARD SUNRISE SUNDAY MORNING. LONG TERM... REMNANTS OF DENNIS/500 MB LOW/VORT MAX WILL BE IN NO HURRY TO EXIT LOWER MICHIGAN ON SUNDAY...ASSURING ANOTHER DAY OF SCATTERED SHOWER AND THUNDERSTORM ACTIVITY...AS DEEP MOISTURE LINGERS. WITH NO CHANGE IN THE AIRMASS...MAXES WILL CONTINUE TO RUN IN THE 85 TO 90 DEGREE RANGE. MODELS HAVE TRENDED SLIGHTLY FASTER WITH THE SHORTWAVE TROUGH/COLD FRONT FOR LATE MONDAY/MONDAY NIGHT. HAVE PUSHED UP THE TIMING OF THE SCATTERED 50 POPS TO LATE MONDAY AFTERNOON...CONTINUING INTO THE EVENING. THIS IDEAL TIMING WILL ALLOW FOR THE POTENTIAL OF SEVERE WEATHER...AS 0-1 KM CAPES PROGGED TO CLIMB OVER 2000 J/KG. REGION WILL BE IN THE RIGHT ENTRANCE REGION OF A 90 KNOT JET AT 250 MB...PROVIDING THE LARGE SCALE ASCENT. 0-6 KM SHEAR LOOKS TO BE AT LEAST 30 KNOTS...TO MAYBE UP TO 40 KNOTS. TWO QUICK AND EASY FIELDS TO LOOK AT FOR DIAGNOSING SEVERE WEATHER IS THE SPC SIGNIFICANT TORNADO PARAMETER AND SUPERCELL COMPOSITE PARAMETER...WHICH IS FORECASTED TO BE BETWEEN 1.5 TO 1.8 AND AROUND 4 RESPECTIVELY OVER MUCH OF SOUTHEAST MICHIGAN (00Z TUESDAY)...PER 00Z GFS. SEE SPC HOMEPAGE FOR EXPLANATION OF FORMULAS. THE GOOD NEWS IS THE GFS IS OVERDOING THE CAPES...AS SURFACE DEW POINTS ARE PROGGED TO CLIMB INTO THE MID 70S. ALSO...MID LEVEL LAPSE RATES ARE UNIMPRESSIVE...AS THE UPPER LEVEL TROUGH WILL BE WEAKENING WITH TIME AS IT HEADS INTO EASTERN CANADA. NONE-THE-LESS...STILL WORTHY MENTION OF SEVERE STORMS (WIND HAZARD) IN HWO DUE TO THE MODERATE INSTABILITY AND 500 MB WIND SPEEDS INCREASING TO 40+ KNOTS. GFS MOS INDICATING MAXES IN THE LOWER 90S WHICH IS POSSIBLE WITH 850 MB TEMPS OF 18 TO 20 C. HIGH PRESSURE TO BUILD INTO LOWER MICHIGAN ON TUESDAY...PUTTING AN END TO THE LOW LEVEL COLD ADVECTION TUESDAY MORNING. GOOD SUBSIDENCE/DRY AIR PROGGED TO WORK INTO THE REGION....WITH CU RULES INDICATING ONLY SCT CU. PLENTY OF SUNSHINE...COUPLED WITH A WARM START TO THE DAY (MINS 65 TO 70 DEGREES) SHOULD ALLOW MAXES TO CLIMB INTO THE LOW TO MID 80S. HIGH PRESSURE WILL REMAIN PARKED OVER SOUTHEAST MICHIGAN TUESDAY NIGHT...SETTING UP WHAT APPEARS TO BE A GOOD RADIATIONAL COOLING NIGHT. POTENTIAL FOR THE NORMALLY COOLER SPOTS IN SOUTHEAST MICHIGAN TO DROP INTO THE 50S. STILL A LITTLE TOO FAR OUT IN TIME TO GO SIGNIFICANTLY BELOW NORMAL....AS INCREASING HIGH CLOUDS COULD BE A PROBLEM. WILL CARRY MINS AROUND 60 DEGREES. FAST ZONAL FLOW EXPECTED OVER THE FAR NORTHERN CONUS LATE IN THE WORK WEEK. A FRONTAL BOUNDARY LOOKS TO BE DRAPED OVER THE NORTHERN GREAT LAKES. 00Z WRFXX CORFIDI VECTORS SUGGESTS STORMS MAY SNEAK INTO SOUTHERN LOWER MICHIGAN. TO FAR OUT IN THE FORECAST TO WORRY ABOUT MCS...AND WILL THUS KEEP THE FORECAST DRY...WITH MAXES AROUND 90 DEGREES. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE.
