NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at May 24, 1:48 PM EST, 6 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 248 PM EDT THU MAY 24 2001 KGRR-88D SHOWS PCPN CONTINUING TO DEVELOP ACROSS THE NRN CWA IN AN AREA OF GOOD LOW LVL CONVERGENCE ALONG A PSEUDO WARM FRONT. SLIGHTLY HIGHER DWPTS AND INSTABILITY HAVE FOCUSED ATTENTION TO THAT AREA. THIS IS ALSO THE AREA OF HIGHER HELICITY VALUES. WILL HAVE TO CONTEND WITH THAT PCPN FOR A FEW MORE HOURS. UPR LOW CONTINUES TO SPIN OVR SE IOWA. PSEUDO DRY SLOT WAS NOTED WORKING ITS WAY NORTH FROM INDIANA. THE INCREASED INSTABILITY ASSOCIATED WITH THIS FEATURE ALONG WITH STEEPENING LAPSE RATES COULD LEAD SOME OF THE STORMS THAT FORM TO SEVERE LEVELS THIS EVENING. THE RUC SHOWS CAPE INCREASING TO 1400 J/KG AND LI/S DROPPING TO -2. P-H2O VALUES ONLY CLIMB TO AROUND AN INCH SO I WOULDN/T EXPECT HEAVY RAIN TO BE A BIG THREAT. RUC SOUNDINGS SHOW VERY LOW WBZ HTS SIGNALLING HAIL AS THE MAIN THREAT. THE SHORT RANGE MODELS CONTINUE TO SHOW THE UPR LOW SPINNING AROUND THE WRN LAKES THRU SATURDAY. THE ETA ACTUALLY DEEPENS THE SFC LOW A BIT AS A WAVE ROTATES AROUND THE NORTHERN PERIPHERY OF THE SYSTEM. THE AVN ISNT AS AGGRESSIVE. I/VE SEEN IN THE PAST WHERE THE UPR LOW WON/T MOVE AT ALL...NEVER GETS KICKED OUT...AND JUST SIMPLY CONTINUES TO FILL UNTIL IT DISSIPATES. MODELS ARE HINTING AT A SIMILAR SITUATION WITH CORE HT RISES AND WARMING H5 TEMPS THRU SATURDAY. UNDER THAT SCENARIO WE/D SEE A LITTLE BRIGHTER SKIES AS THE WEEKEND PROGRESSED WHICH OF COURSE WOULD LEAD TO MORE HEATING AND INSTABILITY AND A SKEW TOWARD MORE TSRA RATHER THAN SHRA. HOWEVER WITH WARMING ALOFT LAPSE RATES WOULDN/T BE AS STEEP DIMINISHING THE THREAT FOR STRONGER STORMS. FOR FRIDAY THROUGH SATURDAY NIGHT WE/LL CONTINUE WITH THE MO CLDY THEME AND MENTION CHC POPS WITH THUNDER POSSIBLE. VARIOUS SHORT WAVES ARE PROGGED TO SWEEP THROUGH THE CWA. WOULDNT BE SURPRISED TO SEE A LITTLE SUNSHINE DURING THE MORNING BUT CU ROUTINE SHOWS LOTS OF POTENTIAL FOR CU DEVELOPMENT THRU THE PERIOD. FOR SIMPLICITY WILL CALL IT CONSIDERABLE CLOUDINESS. 93 EXTENDED FORECAST DISCUSSION... MODELS ARE SIMILAR IN TRACKING THE UPPER LOW EAST OF MI AND WEAKENING IT ON MONDAY. WILL CONTINUE TO FEATURE GRADUALLY IMPROVING CONDITIONS THROUGH THE EXTENDED...WITH LESS IN THE WAY OF PRECIPITATION AND MODERATING TEMPERATURES. ON TUESDAY AND WEDNESDAY...THE EUROPEAN SHOWS A DIGGING SHORTWAVE DROPPING INTO THE GREAT LAKES REGION...WHILE THE OTHER MODELS SHOW RIDGING. AT THIS POINT...WILL HOLD ONTO IDEA OF RIDGING...AND KEEP THE FORECAST DRY FOR THE MIDDLE PART OF THE WEEK. 41 .GRR...NONE.
MIZ037>040-043>046-050>052-056>059-064>067-071>074-250400- SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE GRAND RAPIDS MI 845 PM EDT THU MAY 24 2001 ...COLD AIR FUNNELS POSSIBLE ACROSS SOUTHWEST LOWER MICHIGAN... FUNNEL CLOUDS HAVE BEEN SIGHTED ACROSS SOUTHWEST LOWER MICHIGAN THIS EVENING. RECENTLY... REPORTS OF FUNNELS WERE RECEIVED FROM THE KALAMAZOO AREA IN ASSOCIATION WITH A THUNDERSTORM WHICH IS MOVING NORTH THROUGH THAT AREA. THESE FUNNEL CLOUDS ARE LIKELY COLD AIR FUNNELS... WHICH DO NOT TYPICALLY COME IN CONTACT WITH THE GROUND OR CAUSE ANY DAMAGE. GENERALLY... FUNNEL CLOUDS DEVELOP AND OCCUR IN CONJUNCTION WITH WELL DEVELOPED AND INTENSE THUNDERSTORMS WHICH HAVE FORMED IN A WARM MOIST AIR MASS. THUNDERSTORMS OF THIS VARIETY AND INTENSITY FORM ALONG AND SOME DISTANCE AHEAD OF A STRONG COLD FRONT. WHEN FUNNEL CLOUDS ARE IN ASSOCIATION WITH THIS TYPE OF THUNDERSTORM THEY FREQUENTLY DIP TO THE GROUND AND HAVE SUFFICIENT FORCE TO CAUSE DAMAGE ALONG THEIR PATH. A FUNNEL CLOUD THAT TOUCHES THE GROUND IS CALLED A TORNADO. AN ENTIRELY DIFFERENT CONDITION EXISTS OVER SOUTHWEST LOWER MICHIGAN THIS EVENING. THERE ARE NO STRONG COLD FRONTS IN THE AREA... AND THERE IS LITTLE POTENTIAL FOR INTENSE THUNDERSTORMS. RESEARCH STUDIES OF FUNNEL CLOUD OCCURRENCES DURING THE PAST SEVERAL YEARS INDICATE THAT A SOMEWHAT DIFFERENT SPECIES OF FUNNEL CLOUD FORMS WHEN WEATHER CONDITIONS ARE SIMILAR TO THOSE OF TODAY. THESE ARE CALLED COLD AIR FUNNELS AND ARE NOT AS VIOLENT AS THOSE ASSOCIATED WITH WARM AND HUMID CONDITIONS. THESE STUDIES OF COLD AIR FUNNELS SHOW THEY RARELY DO ANY DAMAGE. THESE FUNNEL CLOUDS NORMALLY PROTRUDE A FEW HUNDRED FEET DOWNWARD FROM THE PARENT CLOUD...ROTATE OR SPIN LIKE A TOP...AND LAST A FEW MINUTES BEFORE DISSIPATING. REPORTS OF SMALL FUNNEL CLOUDS MAY BE EXPECTED OVER SOUTHWEST LOWER MICHIGAN UNTIL SUNSET... WHEN NEAR SURFACE TEMPEORATURES COOL AND THE ATMOSPHERE STABILIZES.
