NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jul 25, 9:00 PM EST, 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1000 PM EDT WED JUL 25 2007 LATEST UPDATE...SHORT TERM... .SYNOPSIS... (430 PM EDT WED JUL 25 2007) THE UPPER LEVEL LOW PRESSURE SYSTEM THAT AS OF 18Z WAS CENTERED OVER EASTERN CENTRAL OHIO WILL CONTINUE TO DRIFT WEST NORTHWEST TO BE SITUATED OVER CENTRAL LOWER MICHIGAN BY MID AFTERNOON THURSDAY. THIS SYSTEM WILL BRING WITH IT SHOWERS AND ISOLATED THUNDERSTORMS THROUGH THURSDAY NIGHT. A CANADIAN COLD FRONT WILL DIVE SOUTHEAST FROM CENTRAL CANADA THURSDAY...REACHING LOWER MICHIGAN FRIDAY. THAT WILL PUSH THE UPPER LEVEL STORM OUT OF THE WAY BUT BRING ENHANCED SHOWERS AND THUNDERSTORMS TO ALLEVIATE TO SOME EXTENT THE DEVELOPING DROUGHT OVER SOUTHERN LOWER MICHIGAN. LOCALLY HEAVY RAINFALL IS MORE LIKELY THAN SEVERE WEATHER THROUGH THIS TIME. THE GREATEST THREAT FOR LOCALLY HEAVY RAINFALL IS SOUTH OF INTERSTATE 96 FROM TONIGHT THROUGH FRIDAY AFTERNOON. COOLER CANADIAN AIR WILL FOLLOW FOR THE WEEKEND. .SHORT TERM... (1000 PM EDT WED JUL 25 2007) LATEST WV IMAGERY SHOWS THE CENTER OF THE UPPER LOW HAS ROTATED TO NEAR THE WRN SHORES OF LAKE ERIE AS OF 0115Z. PRETTY STRONG VORT MAX ROTATING AROUND THE UPPER LOW HAS ROTATED TO SE LOWER NEAR KOZW/KARB. SHOWERS AND STORMS THAT DEVELOPED EARLIER HAVE DIMINISHED IN COVERAGE AND INTENSITY A BIT...HOWEVER A FEW CONTINUE EVEN WITH SFC BASED INSTABILITY ON THE WANE. THIS WAVE OVER SE LOWER WILL ROTATE SOUTH OF THE STATE LINE TONIGHT...ALLOWING SOME SUBSIDENCE TO SETTLE IN BEHIND IT. SOME CLEARING IS NOTED MOVING TOWARD THE CWFA FROM THE ENE. ANOTHER POSSIBLE WAVE MOVING ENE FROM CENTRAL LAKE ERIE COULD AFFECT THE CWFA LATER TONIGHT. BEST MOISTURE IS PROGGED TO BE OVER THE WRN CWFA WHERE NOT AS MUCH SUBSIDENCE WILL BUILD IN. ELEVATED LI/S ARE FCST TO REMAIN BELOW ZERO THROUGH THE NIGHT THERE. WE WILL MAINTAIN A THREAT OF PCPN THROUGH THE NIGHT WITH THE UPPER LOW NEARBY AND THE NEXT WAVE MOVING IN LATER. COVERAGE SHOULD NOT BE AS WIDESPREAD WITHOUT THE DIURNAL BOOST TO HELP. WE ALSO HAVE ADDED A MENTION OF PATCHY FOG TO THE ZONES. DEW POINTS IN THE 60S...SOME RAINFALL...AND SOME CLEARING SKIES MOVING IN SHOULD ALLOW FOR SOME PATCHY FOG TO DEVELOP. WE DO NOT EXPECT FOG WILL BE A BIG ISSUE WITH AT LEAST 10 KTS ALOFT TO HELP KEEP THINGS MIXED SOMEWHAT JUST ABOVE THE SFC. STRATUS DEVELOPMENT LOOKS TO BE MORE FAVORED WITH PLENTY OF LOW LEVEL MOISTURE AROUND AND SOME WIND ALOFT. THURSDAY INTO THURSDAY NIGHT WILL SEE THE UPPER LOW OVER THE AREA WITH THE BEST INSTABILITY OVER THE SOUTHERN AND CENTRAL CWA. THERE IS LITTLE QUESTION THAT THERE WILL BE SHOWERS AND THUNDERSTORMS AROUND...SO I INCREASED THE POP TO LIKELY. THE DEEP LAYER SHEAR IS MUCH LESS... UNDER 20 KNOTS THURSDAY 06Z THROUGH 18Z... SO THE STORMS THEN WILL MORE LIKELY BE JUST VERY WET THUNDERSTORMS. VERTICAL TOTALS ARE IN THE 25 TO 28C RANGE THURSDAY INTO THURSDAY NIGHT. THE SURFACE BASED CAPE IS NEAR 1000 J/KG DURING THE DAY WITH 850 MB CAPE MOSTLY NEAR THE LAKE SHORE. THE BEST COMBINATION OF 850 MB AND SURFACE BASED CAPE IS THURSDAY NIGHT SOUTH OF INTERSTATE 96. THAT WILL BE ENHANCED ON FRIDAY DURING THE DAY AS THE COLD FRONT MOVES THROUGH. BOTTOM LINE IS A RATHER WET PERIOD IS LIKELY UNTIL THE FRONT COMES THROUGH FRIDAY EVENING. && .LONG TERM... (434 PM EDT WED JUL 25 2007) ONLY SIGNIFICANT FORECAST ISSUE IN THE EXTENDED PERIOD IS FOR SATURDAY MORNING AS THE NAM IS STILL QUICKER THAN THE GFS IN PUSHING THE SURFACE FRONT THROUGH. THE GFS HAS A WEAK WAVE ON THE FRONT... LINGERING HIGHER DEW POINTS... AND STILL SOME H5 TROUGHING ALOFT THROUGH SATURDAY. WILL KEEP SOME SMALL CHANCE POPS IN THE FCST ON SATURDAY MORNING ALONG AND SOUTH OF INTERSTATE 94. OTHERWISE THE EXTENDED PERIOD FEATURES A LARGE/DRY SURFACE HIGH SETTLING OVER THE GREAT LAKES REGION SUNDAY AND REMAINING IN PLACE FOR MOST OF THE FOLLOWING WEEK. WILL CALL FOR DRY/PLEASANT WEATHER SATURDAY NIGHT THROUGH TUESDAY WITH TEMPS CLOSE TO CLIMO. && .AVIATION... (338 PM EDT WED JUL 25 2007) SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON WITH SOME DECREASE IN COVERAGE AND INTENSITY AFTER THE SUN GOES DOWN THIS EVENING. SOME FOG IS POSSIBLE IN AREAS WHERE HEAVY RAIN FALLS. GIVEN THE NATURE OF THE PRECIP...WENT WITH VCSH FOR ALL TAF SITES EXCEPT AZO AND BTL WHERE THE BEST COVERAGE OF PRECIP IS EXPECTED. && .MARINE... (434 PM EDT WED JUL 25 2007) A WEAK SURFACE PRESSURE PATTERN WILL RESULT IN WAVE HEIGHTS OF A FOOT OR LESS. SEE THE SHORT TERM FOR DETAILS ON THE THUNDERSTORMS BUT WE WILL HAVE ENHANCED CONVECTION THIS EVENING INTO TONIGHT AS THE JET EXIT REGION MOVES OVER THE AREA OF GREATEST INSTABILITY... WHICH HAPPENS TO BE THE NEAR SHORE AREA SOUTH OF GRAND HAVEN TONIGHT. MOSTLY THESE STORMS WILL HAVE HEAVY RAINFALL AND CLOUD TO SURFACE LIGHTNING WHICH WILL BE THE GREATEST HAZARDS FROM THESE STORMS. ADDITIONAL THUNDERSTORMS WILL CONTINUE INTO FRIDAY. && .HYDROLOGY... (1000 PM EDT WED JUL 25 2007) SOME LOCAL ISOLATED AREAS HAVE SEEN RAINFALL ON THE ORDER OF AROUND 2 INCHES PLUS THIS EVENING FROM THE SLOW MOVING AND SOMETIMES TRAINING SHOWERS AND STORMS. FLOOD ADVISORIES HAVE BEEN ISSUED FOR THE HEAVIEST RAINFALL...HOWEVER NO MAJOR PROBLEMS HAVE BEEN REPORTED. LOCALLY HEAVY RAINFALL FROM SLOW MOVING THUNDERSTORMS WILL LIKELY RESULT IN AREAS THAT NEED URBAN AND SMALL STREAM FLOOD STATEMENTS. WITH THE 3 HOUR FLASH FLOOD GUIDANCE VALUES OVER 3 1/2 INCHES IN ALL OF OUR COUNTIES...FLASH FLOODING IS NOT LIKELY...HOWEVER IT IS ALSO NOT OUT OF THE QUESTION. THAT WOULD MOSTLY BE FOR AREAS SOUTH OF INTERSTATE 96 INTO FRIDAY AFTERNOON WHERE THE INSTABILITY WILL BE THE GREATEST. LARGE SCALE RIVER FLOODING AT THIS POINT DOES NOT SEEM TO BE AN ISSUE. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE. LM...NONE. && SHORT TERM: NJJ/WDM LONG TERM: OSTUNO AVIATION: OSTUNO MARINE: WDM HYDROLOGY: NJJ/WDM
