Area forecast discussion, Jun 28, 5:15 PM EDT, 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 515 PM EDT TUE JUN 28 2005 .SHORT TERM... THE MAIN CHALLENGE DEALS WITH THE POTENTIAL FOR SOME SEVERE WEATHER LATER WEDNESDAY AND INTO THURSDAY AM. A STRONGER COLD FRONT IS SHOWN TO PUSH THROUGH THE REGION THURSDAY MORNING AND INTO THE EARLY AFTERNOON HOURS. THE LATEST RUN OF THE NAM40 SHOWS BULK SHEAR VALUES 0 TO 6 KM CLIMBING TO OVER 40 KNOTS...SO ORGANIZED SEVERE WEATHER IS POSSIBLE. CAPE VALUES OF OVER 2000 J/KG SUGGEST PLENTY OF INSTABILITY WILL BE PRESENT. DECENT VEERING OF THE LOW LEVEL WINDS WILL BE PRESENT WITH SOME HELICITY VALUES AROUND 200 M2/S2...THUS SOME STORMS MAY CONTAIN STRONGER ROTATION. ALOFT ABUNDANT DIFFLUENCE IS SEEN WITH 300 MB WINDS INCREASING TO 70+ KNOTS. I WENT AHEAD AND INCREASED PROBABILITIES TO LIKELY FOR THUNDERSTORMS LATE WEDNESDAY NIGHT INTO THU. NOTICED THE SHALLOW FRONT SLIPPING DOWN FROM THE NORTH TONIGHT. IT REMAINS UNSTABLE ALOFT THROUGH THE NIGHT...THUS CONVECTION COULD GO AT ANY TIME. I DO NOT SEE ANY LLJ NOSING INTO THE FRONT...BUT IF ONE DOES DEVELOP...A GOOD SET UP FOR HEAVY RAIN EXITS. WILL NEED TO MONITOR THROUGH THE NIGHT. I DID KEEP THE CHANCE FOR SOME THUNDERSTORMS GOING THROUGH THE NIGHT. THE SLOW MOVEMENT IN COMBINATION WITH TROPICAL AIRMASS IN PLACE SUGGESTS LOCALLY AN INCH OR TWO OF RAIN COULD FALL. WITH THE FRONT ACROSS THE AREA ON WEDNESDAY...SCATTERED CONVECTION IS POSSIBLE...SOME MAY BE PULSE SEVERE. ANOTHER WARM AND HUMID DAY IS EXPECTED WITH HIGHS GOING UP INTO THE UPPER 80S. DEPENDING ON HOW CONVECTION EVOLVES UPSTREAM...WE MAY SEE THUNDERSTORMS WITH DAMAGING WIND ARRIVING LATER WEDNESDAY NIGHT. OUR BOUNDARY LAYER WILL BE WELL MIXED AND WE HOLD ONTO THE INSTABILITY THROUGH THE NIGHT WITH INCREASING WIND FIELDS. WILL KEEP THUNDERSTORMS IN THE FORECAST. .LONG TERM... NO BIG CHANGES WITH GOING EXTENDED FORECAST. WE CONTINUE TO SEE THE PATTERN CHANGE SCHEDULED FOR THE END OF THIS WEEK THROUGH THE FIRST HALF OF THE WEEKEND. UPPER LEVEL TROUGH BRUSHES THROUGH THE GREAT LAKES FRIDAY AND SATURDAY...RETREATING NORTHWARD LATE SATURDAY. THIS PULLING NORTH OF THE LOW WILL HELP TO ALLOW WEAK RIDGING TO RETURN TO LOWER MICHIGAN FOR THE SUNDAY AND EARLY NEXT WEEK TIME FRAME. TEMPERATURES STILL APPEAR TO BE MORE SEASONAL TO CLOSE OUT THE WEEK...WITH 850MB TEMPS COOLING TO AROUND 10 TO 12 DEG C FOR FRIDAY AND SATURDAY...WHICH USING 74 PERCENT RULE OF SUNSHINE RESULTS IN MAX SFC TEMPERATURES IN THE UPPER 70S. WARM POOL OF 20 TO 22 DEG C 850MB TEMPS ARE BEGINNING TO BE PICKED UP ACROSS THE CENTRAL ILLINOIS ON MONDAY. MODELS ARE PROGGING A LOW LEVEL JET POINTED TOWARDS THE GREAT LAKES REGION MONDAY AND TUESDAY...WHICH SHOULD HELP TO ADVECT IN WARMER TEMPS. GULF MOISTURE RETURNS ON THE RETURN FLOW FROM THE SFC RIDGE OFFSHORE OF THE CAROLINAS. THIS WILL HELP TO INCREASE DEW POINTS AND WITH INCREASING INSTABILITY LATE IN THE WEEKEND EARLY NEXT WEEK...HAVE MAINTAINED THE THREAT FOR SCATTERED SHOWERS AND THUNDERSTORMS. .GRR WATCHES/WARNINGS/ADVISORIES...NONE. && MJS BEACHLER
