Area forecast discussion, Jul 28, 3:30 PM EDT, 5 hours 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 330 PM EDT WED JUL 28 1999 ...MAIN CONCERN CONTINUES TO BE THUNDERSTORM POTENTIAL FOR THIS THIS EVENING AND OVERNIGHT... .TONIGHT... HIGH PRESSURE CONTINUES OVER THE CENTRAL US PUTTING GREAT LAKES REGION IN A NW FLOW AROUND PERIMETER ALLOWING SYSTEMS TO SLIDE SE INTO FA. LATEST WV IMAGERY SHOWS DRYING AT THE MID LEVELS WITH A SERIES OF VORTS RIDDING ALONG UPPER LEVEL JET EFFECTING OUR WEATHER AS EARLY AS 19 OR 20Z AS SUGGESTED BY THE ETA WHICH INITIALIZED NICELY IN RELATION TO VORTS REPRESENTED ON WV. CURRENT SURFACE ANALYSIS SHOWS WARM FRONT THROUGH CWA AT 3PM AS EVIDENT BY DEWPOINTS RETURNING INTO THE THE UPPER 60S TO LOWER 70. ASSOCIATED TROF MOVING INTO NRN MICH EXTENDING BACK INTO WI AND PROGGED TO REACH WRN MICH CLOSER TO 23Z...BY BOTH THE NGM AND ETA MODELS. DESPITE TIMING OF FRONT SW LOWER MI ALREADY UNSTABLE WITH CAPES ABV 4500 J/KG AND LIS GREATER THAN -10. SOME CONVECTION TRIED TO FIRE LAKE BREEZE NEAR KSBN...ALTHOUGH LOOKING FOR BEST CHANCE OF THUNDERSTORMS DEVELOPMENT CLOSER TO FROPA. WITH ALL THIS INSTABILITY...NOT TO MENTION THE GOOD SHEAR OVER GREAT LAKES REGION...ANY TS DEVELOPMENT COULD REACH SEVERE LEVELS CLOSER TO ARRIVAL OF FRONT. .THURSDAY AND THURSDAY NIGHT... AS FOR THURSDAY LOOKS LIKE ANOTHER REPEAT WITH A FRONTAL SYSTEM MOVING OVER FA LATE IN THE DAY AND EXTENDING OUT OVER CENTRAL MICH AFTER 06Z. WITH ALREADY HIGH DEW POINT AND ANOTHER APPROACHING FRONT ITS HARD TO REMOVE ANY CHANCE OF SHOWERS AND THUNDERSTORMS WITH THE UNSTABLE ATMOSPHERE ALREADY IN PLACE. THE DIFFERENCE FROM TODAY IS THE LACK OF UPPER LEVEL SUPPORT. ALTHOUGH THIS SFC FRONT APPEARS MORE ORGANIZED AS IT MOVES OVER FA WITHOUT DEPTH...OR UPPER LEVEL SUPPORT...IT WILL BE HARDER TO FIRE THUNDERSTORMS. MOS GUIDANCE BACKED DOWN FROM 99 TO 96 DEGREES FOR GRR WHICH MAY STILL BE TO HIGH. WILL BACK OFF SLIGHTLY ON TEMP TO AROUND OR LOWER 90S. WITH THESE TEMPS AND RELATIVELY HIGH DEW POINTS 92/70 WOULD PRODUCT A HEAT INDEX NEAR 100...SO REGARDLESS THURSDAY WILL BE A HOT ONE. .FRIDAY... LOOKS LIKE A BREAK IN THE PATTERN FOR FRIDAY AS MODELS CONTINUE SHOW HIGH OVER CENTRAL AMPLIFYING OVER MICH. THIS WILL KEEP ANY SYSTEMS AWAY FROM MICH...THUS A DRY FORECAST. HIGH TEMPS SHOULD CONTINUED IN THE LOWER AND REACHING INTO THE MID 90 FOR AREAS AROUND CWA. MCINERNEY .IN THE EXTENDED... FLOW ALOFT BEGINS TO BECOME A BIT MORE ZONAL ACRS THE REGION...AS SHORTWAVE ENERGY MOVES ACROSS SOUTHERN CANADA WHICH IN TURN DAMPENS THE RIDGING SOMEWHAT. MAIN WX PLAYER IN THE EXTENDED IS SHORTWAVE THAT SWINGS THROUGH THE NRN GRT LKS ON SATURDAY WHICH PUSHES A COLD FRONT THROUGH THE FCST AREA ON SATURDAY AS WELL. RIDGING BUILDS INTO THE AREA BEHIND THE FRONT FOR SUNDAY AND MONDAY...WHICH WILL PROVIDE COOLER AND LESS HUMID CONDITIONS. DUKESHERER .GRR...NONE.
