NWS Detroit, MI wrote its last area forecast discussion before the first event at Jul 27, 6:00 PM EST, 2 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 700 PM EDT THU JUL 27 2006 .AVIATION... EXPECT THUNDERSTORMS TO INCREASE IN THE KDTW/KDET FORECAST AREAS EARLY IN THE FORECAST AS AREA OF THUNDERSTORMS LIFTS/BUILDS IN THIS DIRECTION IN ADVANCE OF AN APPROACHING SHORTWAVE. NORTHWARD MOVING OUTFLOW FROM EARLIER CONVECTION IN IL/IN IS ALSO HELPING TO FOCUS THIS ACTIVITY WHICH IS MOVING INTO RIBBON OF INSTABILITY (2000+ J/KG SBCAPES ACROSS LOWER MICHIGAN). WILL KEEP SHOWERS IN THE FORECAST THROUGH 05Z...AND TEMPO IN THUNDERSTORMS FROM 01Z-05Z. A FEW OF THESE STORMS MAY CLIP KFNT AS WELL...BUT WILL ONLY TEMPO IN AN HOUR OR TWO TO START THE FORECAST. OTHERWISE...WITH ABUNDANT LOW LEVEL MOISTURE AND WEAK WINDS (AFTER THE STORMS PASS)...EXPECT FOG TO DEVELOP...WITH CEILINGS ALSO ON THE CUSP OF IFR/MVFR. WILL MAINTAIN THE PREVIOUS FORECAST OVERNIGHT AT THIS TIME. THIS WILL BURN OFF ON FRIDAY...AND WILL TREND IN CLEARING SKIES AND VFR CONDITIONS BY LATE MORNING. && .PREV DISCUSSION...ISSUED AT 418 PM SHORT TERM...TONIGHT AND FRIDAY COMPLEX SURFACE AND UPPER AIR PATTERN OVER THE REGION THIS AFTERNOON. A TIGHT SURFACE PRESSURE GRADIENT IS IN PLACE OVER THE OHIO RIVER VALLEY WITH A NUMBER OF SURFACE TROUGHS LOCATED ALONG THE BOUNDARY FROM MISSOURI TO LOWER MICHIGAN. WATER VAPOR IMAGERY SHOWS A SHORTWAVE MOVING FROM THE UPPER MIDWEST INTO THE CENTRAL GREAT LAKES WITH A PLUME OF MID LEVEL MOISTURE HEADING TOWARDS SOUTHERN MICHIGAN. THE MORNING SOUNDING OUT OF LINCOLN ILLINOIS HAD A PW OF 1.88 INCHES WHICH IS REPRESENTATIVE OF THE ATMOSPHERE THAT WILL BE MOVING OVER SOUTHERN MICHIGAN THIS AFTERNOON AND EVENING. ABUNDANT CLOUD COVER TODAY HAS LIMITED INSTABILITY A BIT BUT DEWPOINTS IN THE LOW 70S STILL YIELD UP TO 2500 J/KG OF SURFACE BASED CAPE OVER SOUTHEAST LOWER. MID LEVEL INSTABILITY IS NOT IMPRESSIVE THOUGH WITH 500MB TEMPS OF -6C AND LAPSE RATES AROUND 7 C/KM. 0-6 KM BULK SHEAR IS ONLY AROUND 20 KNOTS AND FREEZING LEVELS AROUND 16000 FEET. ALTHOUGH AN ISOLATED SEVERE STORM CANNOT BE RULED OUT WITH GOOD PRECIP LOADING...THINK A GREATER CONCERN FOR THIS EVENING WILL BE HEAVY RAIN. THE TWO MAIN FEATURES TO WATCH FOR CONVECTION TONIGHT ARE THE SURFACE TROUGH OVER THE SOUTHERN ILLINOIS/INDIANA BORDER AS IT COLLIDES WITH THE SHORTWAVE DROPPING DOWN FROM THE NORTH. STORM MOTION IS ONLY EXPECTED TO BE AROUND 15 MPH TO THE EAST NORTHEAST. THIS FLOW WILL GENERALLY BE LINED UP PARALLEL TO THE BOUNDARY SO SOME TRAINING OF STORMS IS POSSIBLE...ESPECIALLY ALONG AND SOUTH OF M-59. AS THESE TWO FEATURES COLLIDE WE COULD SEE A BAND OF THUNDERSTORMS PRODUCE UP TO 2 TO 3 INCHES OF RAIN BUT DO NOT EXPECT THIS TO BE WIDESPREAD. SOME LOCALLY HEAVY RAIN COULD PRODUCE MINOR FLOODING THOUGH AND WILL HAVE TO CLOSELY MONITOR THE GREATER DETROIT AREA THAT RECEIVED HEAVY RAIN ON WEDNESDAY EVENING. AS THE RAIN ENDS FROM NORTH TO SOUTH OVERNIGHT...SKIES ARE EXPECTED TO GRADUALLY CLEAR ACROSS THE NORTHERN COUNTIES. LINGERING LOW LEVEL MOISTURE WILL LEAD TO AREAS OF FOG AGAIN OVERNIGHT BUT WILL DISSIPATE EARLY ON FRIDAY MORNING. DRIER AIR ADVECTING FROM THE NORTH WILL LEAD TO ONLY SCATTERED CLOUDS IN THE NORTH WITH SCT-BKN SKIES IN THE SOUTH. WILL CONTINUE WITH A LOW CHANCE OF THUNDERSTORMS ACROSS OUR SOUTHERN COUNTIES THROUGH FRIDAY AS THE BOUNDARY IS SLOW TO CLEAR THE ENTIRE STATE. LONG TERM...FRIDAY NIGHT THROUGH THURSDAY FRIDAY NIGHT AND SATURDAY... SURFACE FRONT SAGGING SOUTHWARD FROM THE NORTHERN GREAT LAKES REGION TO APPROACH OR ENTER FORECAST AREA SATURDAY AS PER 12Z NAM AND 00Z/12Z WRFHEMI...WITH GFS MORE RELUCTANT TO DO SO. GENERALLY AM PREFERRING GFS SOLUTION GIVEN ITS RECENT CONSISTENCY. AT 500 MB...NORTHWEST FLOW WITH EMBEDDED SHORTWAVE TROUGH IMPULSES FOR THIS PERIOD. 850 TO 500 MB MOISTURE ON THE INCREASE MAINLY NORTH LATE FRIDAY NIGHT...BECOMING MODEST OVER MOST OF THE AREA SATURDAY. 925 MB MOISTURE MODEST AT BEST AND MAINLY SATURDAY...WITH GFS CONSIDERABLY MORE ROBUST THAN NAM. OCCASIONAL MODEST OMEGA ASCENT FRIDAY NIGHT AND SATURDAY...GENERALLY BELOW 5 UBAR/SEC. ALSO...SLIGHT 850 TO 500 MB QVECTOR CONVERGENCE/IMPLIED LIFT SEEN ALONG WITH WEAK LOW LEVEL CONVERGENCE. VERY LIMITED INSTABILITY WANING EARLY FRIDAY EVENING AS INHIBITION INCREASES STEADILY...SO WILL KEEP FORECAST DRY FOR NOW. WILL ALSO KEEP LATE NIGHT MENTION FAR NORTHERN COUNTIES AS MOISTURE/DYNAMICS INCREASE AHEAD OF THE SAGGING COLD FRONT. QUITE UNSTABLE AND RATHER UNCAPPED THROUGHOUT SATURDAY TO WARRANT CHANCE SHOWER/THUNDER MENTION. LIFTED INDICES SATURDAY BECOMING MINUS 5 TO 7 DEGREES CELSIUS...CAPES GENERALLY 2K JOULES...AND 850 TO 500 MB LAPSE RATES 6 TO 7 DEGREES C/KM. ZERO TO 6 KM BULK SHEAR SATURDAY RELATIVELY WEAK...MAINLY BELOW 30 KNOTS...SO SEVERE POTENTIAL WILL BE LIMITED. FROM SATURDAY NIGHT ON... 00Z AND 12Z OPERATIONAL GFS PRETTY MUCH KEEP WAVY SURFACE FRONT NORTH OF FORECAST AREA SATURDAY NIGHT AND SUNDAY...UNLIKE THE 00Z/12Z WRFHEMI...AND ALSO SOMEWHAT SUPPORTED BY GFS ENSEMBLE MEAN. OTHERWISE...SOMEWHAT OF A MODEL CONSENSUS SUPPORTING A PREVAILING BROAD SURFACE RIDGE EXTENDING NORTH ACROSS SOUTHEAST MI INTO THE MIDDLE PART OF NEXT WEEK...WITH RESULTING SUSTAINED PERIOD OF HEAT AND HUMIDITY OVER THE AREA. THE 00Z AND 12Z GFS/06Z DGEX BRING IN COLD FRONT WEDNESDAY...SOME SUPPORT PROVIDED BY THE CANADIAN GLOBAL AND 00Z ECMWF...THOUGH THE 00Z WRFHEMI WAS ABOUT A DAY EARLIER IN BRINGING IN THE COLD FRONT. AVAILABLE MODEL DATA THEN BUILDS IN HIGH PRESSURE BY THURSDAY...USHERING IN TREND TOWARD COOLER WITH LESS HUMID CONDITIONS. AT 500 MB...MODELS AGAIN TODAY SHOW A GRADUAL PROGRESSION EASTWARD OF RIDGE FROM THE NORTHERN PLAINS INTO THE GREAT LAKES THIS WEEKEND AND RESIDING OVERHEAD UNTIL MID PART OF NEXT WEEK...AT WHICH TIME CONSENSUS BRINGS IN WELL DEFINED SHORTWAVE TROUGH. AS WAS THE CASE YESTERDAY...MODELS DEPICT 850 MB TEMPERATURES OF 20 DEGREES CELSIUS PLUS FOR MOST OF EARLY NEXT WEEK...WITH 700 MB TEMPERATURES 10 TO 12 DEGREES C. VERY LITTLE CHANGES MADE TO THE PREVIOUS FORECAST FOR THIS TIME PERIOD. EARLY PART OF NEXT WEEK...WITH HIGH 500 MB HEIGHTS AND WARM TEMPERATURES ALOFT...FAVOR OVERALL RELATIVELY DRY AIR MASS AND CAPPED ENVIRONMENT FOR CONVECTION. LATER FORECASTS MAY HAVE TO DEAL WITH POTENTIAL HEAT ADVISORY CONDITIONS BY MONDAY. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
