Area forecast discussion, May 30, 3:00 AM EST, 2 hours before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 400 AM EDT TUE MAY 30 2006 .DISCUSSION... THE MAIN CONCERNS WITH THIS FORECAST PACKAGE ARE THE RAIN AND THUNDERSTORM POTENTIAL FOR TODAY AND TONIGHT AND THE TEMPERATURES. WATER VAPOR IMAGERY AND RUC SHOW A LARGE RIDGE OVER EASTERN NORTH AMERICA AND A CLOSED LOW OVER NORTHWEST MANITOBA EMBEDDED IN A LONGWAVE TROUGH BLANKETING CENTRAL AND WESTERN CANADA. SHORTWAVES ARE BEING EJECTED OUT OF THE BASE OF THE MANITOBA LOW AND ARE CLIMBING THE RIDGE. THEY ARE LOCATED OVER EASTERN WISCONSIN AND CENTRAL U.P...AND OVER EASTERN NORTH DAKOTA AND MANITOBA. THE FLOW BEHIND THE HIGH CONTINUES TO DRAW GULF MOISTURE NORTH THROUGH THE MISSISSIPPI RIVER VALLEY INTO THE UPPER GREAT LAKES AND WESTERN ONTARIO. SURFACE ANALYSIS DEPICTS A LOW OVER CENTRAL MANITOBA...WITH A COLD FRONT DRAPED THROUGH CENTRAL ONTARIO...CENTRAL LAKE SUPERIOR...AND CENTRAL U.P. INTO EASTERN IOWA. ANOTHER SURFACE RIDGE IS BUILDING FROM WESTERN MONTANA THROUGH THE DAKOTAS INTO NORTHERN MINNESOTA. NUMEROUS SHOWERS AND THUNDERSTORMS WERE DEVELOPING ALONG THE FRONT OVER THE WISCONSIN AND CENTRAL U.P. THE MID LEVEL RIDGE WILL PUSH INTO EASTERN QUEBEC AND CONTINUE TO BLANKET MUCH OF EASTERN CONUS TODAY. THE MANITOBA LOW IS BEING DIVERTED NORTHEAST INTO NORTHEAST MANITOBA BY THE RIDGE. THE SHORTWAVE ATTENDING THIS LOW WILL SWEEP INTO NORTHERN LOWER MICHIGAN AND EASTERN ONTARIO. OTHER SHORTWAVES PIVOTING THROUGH THE BASE OF THE LOW WILL MOVE FROM EASTERN NORTH DAKOTA INTO WESTERN ONTARIO. THE COLD FRONT WILL SHIFT INTO NORTHERN LOWER MICHIGAN AND EASTERN ONTARIO TODAY. GULF MOISTURE OVERRUNNING THE FRONT WILL KEEP SHOWERS AND SOME THUNDERSTORMS FIRING MAINLY OVER EASTERN AND SOUTHERN U.P. 850-500MB Q-VECTOR CONVERGENCE WILL BECOME FOCUSED OVER THE WESTERN U.P. THIS AFTERNOON. HOWEVER...GFS/NAM SHOW THAT THE AIR MASS WILL DRY OUT CONSIDERABLY BELOW 500MB OVER THE WESTERN U.P. BY LATE AFTERNOON. THE MUCAPE VALUES WILL FALL OFF OVER THE FORECAST AREA THROUGH THE AFTERNOON AND BECOME MORE FOCUSED OVER SOUTHERN WISCONSIN AND LOWER MICHIGAN. CLOUD COVER SHOULD LIMIT HEATING. COOLER AIR ADVECTING IN BEHIND THE COLD FRONT SHOULD LIMIT MAX TEMPERATURES TO UPPER 70S TO AROUND 80 TODAY. THE QUEBEC RIDGE WILL TREK A LITTLE EAST TONIGHT...WHILE THE MANITOBA LOW DIVES INTO CENTRAL HUDSON BAY. A SHORTWAVE ACCOMPANYING THIS LOW WILL SWEEP ACROSS WEST AND CENTRAL ONTARIO. ANOTHER WEAK SHORTWAVE WILL RACE ACROSS THE FORECAST AREA. THE COLD FRONT WILL SLIDE SOUTHEAST INTO SOUTHERN LOWER MICHIGAN AND SOUTHEAST ONTARIO. THE RIDGE OVER MONTANA WILL SETTLE SOUTH INTO WYOMING WHILE THE EAST END OF THIS RIDGE SHIFTS OUT OF MINNESOTA INTO LAKE SUPERIOR. LOW LEVEL MOISTURE ACCOMPANYING THE FRONT WILL LIKEWISE SHIFT OUT OF THE FORECAST AREA. THE Q-VECTORS ASSOCIATED WITH THE SHORTWAVES WILL ALSO SHIFT SOUTHEAST AND MUCAPE VALUES WILL DECREASE TO NEAR ZERO OVER THE AREA. THUS CLEARING SHOULD RETURN TO THE AREA. AS MORE COOLER AIR ADVECTS IN BEHIND THE COLD FRONT AND EXPECTED CLOUD COVER...LOWS IN THE UPPER 40S TO LOW 50S LOOK REASONABLY. ANOTHER SHORTWAVE WILL MANEUVER INTO CENTRAL UPPER MICHIGAN ON WEDNESDAY WHILE THE SURFACE RIDGE MOVES OVER THE AREA. A 125KT UPPER LEVEL JET MAX WILL SLIDE ACROSS CENTRAL ONTARIO...PLACING THE U.P. UNDER THE RIGHT ENTRANCE REGION FOR A TIME. DRIER AIR ACCOMPANYING THE RIDGE WILL CONTINUE TO PREVENT SHOWERS FROM OCCURRING. THUS IN SPITE OF THE INSTABILITY...THE DRY AIR WILL LIMIT PRECIPITATION PRODUCTION. AS ONE SHORTWAVE EXITS THE FORECAST AREA WEDNESDAY NIGHT ANOTHER APPROACHES FROM MINNESOTA. THE RIDGE OVER NORTHERN PLAINS WILL EXPAND TO BLANKET THE NORTHERN AND CENTRAL PLAINS. THIS RIDGE WILL BE PUSHING INTO THE UPPER GREAT LAKES. DRY AIR ASSOCIATED WITH THE RIDGE WILL CONTINUE TO KEEP PRECIPITATION OUT OF THE AREA. THE MINNESOTA SHORTWAVE WILL SWEEP THROUGH THE FORECAST AREA ON THURSDAY...WHILE THE SURFACE RIDGE ADVANCES INTO THE UPPER GREAT LAKES. DRY AIR WILL MAINTAIN DRY CONDITIONS. && .MQT...WATCHES/WARNINGS/ADVISORIES...NONE. && DLG
