NWS Marquette, MI wrote its last area forecast discussion before the first event at Aug 17, 2:45 AM EST, 5 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 345 AM EDT SAT AUG 17 2002 CONCERNS WITH THIS PACKAGE REVOLVE AROUND CHANCES FOR SHRA/TSRA AHEAD OF THE COLD FRONT THIS MORNING...THEN HIGH WIND POTENTIAL THROUGH THIS EVENING. LATEST WATER VAPOR IMAGERY AND H4 RUC ANALYSES SHOW A STRONG SHORTWAVE EMBEDDED IN OTHERWISE ZONAL FLOW OVER THE NORTHERN TIER OF THE CONUS. THE LEAD PV ANOMALY ASSOCIATED WITH THE SHORTWAVE IS CURRENTLY SWINGING THROUGH EASTERN NORTH DAKOTA...WITH DISTINCT SUBSIDENCE AND DRYING NOTED TO ITS SOUTH OVER SOUTH DAKOTA AND INTO WEST CENTRAL MINNESOTA. THE RESULTANT SURFACE PRESSURE RISE MAXIMA IS LOCATED OVER SOUTH CENTRAL SOUTH DAKOTA PER THE 06Z MSAS ANALYSIS. SURFACE WIND GUSTS ACROSS CENTRAL SOUTH DAKOTA HAVE BEEN IN EXCESS OF 40 MPH FOR THE PAST SEVERAL HOURS...WITH A FEW GUSTS AROUND 60 MPH NOTED AS WELL. TO THE EAST...A LARGE AREA OF SHRA/TSRA IS ONGOING OVER EASTERN MINNESOTA AND NORTHWEST WISCONSIN. THIS PRECIPITATION IS BEGINNING TO MOVE INTO UPPER MICHIGAN...AND SOME THUNDER SHOULD BEGIN TO MAKE ITS WAY INTO THE WESTERN CWFA OVER THE NEXT FEW HOURS AS THE NEGATIVE H85-H5 DIFFERENTIAL THETA-E VALUES MOVE INTO THE AREA AHEAD OF THE H85 THETA-E RIDGE AND APPROACHING H7-H5 DRY SLOT. CONVECTION WHICH RECENTLY FIRED ALONG THE COLD FRONT OVER NEBRASKA AND IOWA APPEARS TO BE CUTTING OFF SOME OF THE INFLOW INTO THE CONVECTION OVER MINNESOTA AND WISCONSIN...WHICH MAY BE SUPPORTING THE RECENT WEAKENING TREND NOTED WITH THAT CONVECTION. HOWEVER...THERE REMAINS SUFFICIENT MOISTURE...INSTABILITY AND FORCING AHEAD OF THE SHORT WAVE AND SURFACE COLD FRONT TO PRODUCE PCPN...SO WE WILL SEE A PERIOD OF SHRA/TSRA THIS MORNING. CANNOT DISCOUNT THE POSSIBILITY OF SEVERE WEATHER GIVEN THE IMPRESSIVE 45-65KT WINDS BELOW 5K FT ALONG AND AHEAD OF THE COLD FRONT. HOWEVER...WITH LAPS ANALYSES STILL SHOWING A SURFACE BASED INVERSION IN PLACE...ONLY THE STRONGER STORMS SHOULD HAVE A CHANCE TO TRANSPORT SEVERE WINDS TO THE SURFACE AS THE SHOWERS AND THUNDERSTORMS MOVE THROUGH THIS MORNING. THE 00Z MODEL RUNS ARE IN GOOD AGREEMENT THROUGH THE NEXT FEW DAYS...AND WILL ESSENTIALLY GO WITH A BLEND OF ETA/AVN GUIDANCE...LEANING TOWARD THE ETA IN THE SHORT TERM THEN TRENDING TOWARD THE AVN BEYOND 48 HOURS. AS DISCUSSED ABOVE...WILL CONTINUE TO MENTION SHRA/TSRA AHEAD OF THE COLD FRONT AND SHORTWAVE THIS MORNING. THE BEST QG FORCING IS PROGGED TO SWING BY JUST TO OUR NORTH BETWEEN 09Z AND 18Z...WITH DPVA AND ISENTROPIC LIFT AHEAD OF THE FRONT REPRESENTED BY A NICE AREA OF H85-H5 Q-VECTOR CONVERGENCE. ALTHOUGH THE STRONGEST FORCING IS NORTH OF THE CWFA...SUFFICIENT FORCING AND MOISTURE FOR A PERIOD OF PCPN EXTENDS WELL SOUTH THROUGH THE CWFA. ISENTROPIC DOWNGLIDE AND STRONG SUBSIDENCE WILL ARRIVE QUICKLY BEHIND THE FRONT...WORKING TO SCOUR OUT MUCH OF THE CLOUD COVER FROM WEST TO EAST BY THIS AFTERNOON. THIS SUBSIDENCE WILL ALSO HELP IN THE TRANSPORT OF HIGHER WINDS TO THE SURFACE FROM ALOFT. THE ETA IS CONTINUING TO SHOW AN AREA OF 45-55KT WSW WINDS BETWEEN 2K AND 4K FEET FROM LATE MORNING THROUGH THIS EVENING. THIS IS PRIMARILY FOCUSED OVER THE WESTERN CWFA...WITH THE HIGHEST PROGGED SURFACE WINDS IN THE EXPECTED AREA ALONG THE NORTHERN AND WESTERN SIDE OF THE KEWEENAW PENINSULA. THE AFOREMENTIONED SUBSIDENCE AND NEARLY DRY ADIABATIC LAPSE RATE BELOW 4K FEET SHOULD ALLOW A FEW WARNING CRITERIA WIND GUSTS TO OCCUR OVER THE KEWEENAW THIS AFTERNOON AND EARLY EVENING. THE MAIN PRESSURE RISE/FALL COUPLET IS PROGGED TO SWING THROUGH BEHIND THE SURFACE COLD FRONT THIS MORNING...BEFORE THE BETTER GRADIENT AND DEEP LAYER HIGH WINDS WORK INTO THE AREA THIS AFTERNOON. WOULD EXPECT TO SEE SOME POST FRONTAL HIGH GUSTS THIS MORNING AS THE ISALLOBARIC WIND HELPS THINGS OUT. WE MAY THEN HAVE A LULL IN THE HIGHER WINDS BEFORE THINGS PICK UP AGAIN THIS AFTERNOON. WILL GO WITH A HIGH WIND WARNING FOR HOUGHTON AND KEWEENAW COUNTIES...AND AN ADVISORY FOR GOGEBIC...ONTONAGON...BARAGA AND MARQUETTE COUNTIES. WOULD EXPECT THE HIGHEST WINDS IN MARQUETTE COUNTY TO BE CONFINED TO LOCATIONS NORTH AND WEST OF NEGAUNEE...PARTICULARLY IN THE HIGHER TERRAIN WEST OF BIG BAY. HOWEVER...IT WILL BE QUITE BREEZY ACROSS THE ENTIRE U.P. THROUGH THE EVENING HOURS. THE MAIN SHORTWAVE WILL PASS BY TO OUR NORTH TONIGHT...DRAGGING A SECONDARY H5 VOT LOBE AND SOME COOLER AIR DOWN INTO THE AREA AS IT DOES SO. THE ETA PROGS H85 TEMPERATURES OF AROUND 6C BY LATE TONIGHT WITH THE AVN SHOWING AROUND 4C. IN EITHER CASE IT APPEARS WE SHOULD SEE SOME COLD AIR STRATOCU ACROSS MUCH OF THE CWFA LATER TONIGHT. THE GOING FORECAST INCLUDES THE POSSIBILITY OF A FEW LIGHT SHOWERS...AND SEE NO REASON TO REMOVE THAT FROM THE FORECAST AT THIS POINT. EXPECT H85 THERMAL TROUGH AND ASSOCIATED HIGH RH TO LINGER OVER THE CWFA THROUGH SUNDAY BEFORE RETURN FLOW SETS UP BY MONDAY MORNING. THIS SCENARIO SHOULD KEEP THINGS SOMEWHAT CLOUDY OVER THE NORTHERN CWFA...WITH CLEARER SKIES TO THE SOUTH. THIS CORRESPONDS WELL WITH THE GOING FORECAST...SO DO NOT PLAN ON ANY SUBSTANTIVE CHANGES. THE NEXT CHANCE OF PCPN STILL LOOKS LIKE IT WILL HOLD OFF UNTIL WEDNESDAY AS A SHORTWAVE PROPAGATES THROUGH THE ZONAL FLOW ALONG THE US/CANADIAN BORDER. .MQT...HIGH WIND WARNING TODAY THROUGH THIS EVENING MIZ001-003...HIGH WIND ADVISORY TODAY THROUGH THIS EVENING MIZ002-004-005-009...GALE WARNING LAKE SUPERIOR.
