AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 405 AM EDT THU APR 18 2002 SFC HIGH CENTER IS BEGINNING TO PUSH NE OF MI EARLY THIS MORNING... WITH MOIST SE RETURN FLOW QUICKLY APPROACHING THE STATE. SEVERAL AREAS OF CONVECTION HAVE DEVELOPED OVERNIGHT...AND ARE NOW AFFECTING ERN ND...MUCH OF MN AND PORTIONS OF WRN WI AND NE IA. SVR TSRA WATCH BOX WAS RECENTLY ISSUED FOR PORTIONS OF THIS AREA WHERE CONVECTION IS BEING FUELED BY A 60 KT 850 MB JET AND THETA-E RIDGE...AND FOCUSED NORTH OF A WARM FRONT ASSOCIATED WITH A DEVELOPING LOW PRES SYSTEM IN THE PLAINS. MAIN SHORT TERM CONCERN IS TSRA AND SVR WX POTENTIAL FOR TODAY AND TONIGHT AS THIS SYSTEM MOVES THRU MI. THEN WX QUIETS AND COOLS FOR FRIDAY AND SATURDAY AS COLD CANADIAN HIGH PRES SETTLES INTO THE REGION. TODAY...WARM FRONT REACHES NRN LWR MI BY MIDDAY AND THEN PROGRESSES NORTHWARD TO ERN UPR MI BY 00Z FRI. THERE WILL BE QUITE OF BIT OF DRY/STABLE AIR TO OVERCOME DURING THE ONSET PER 00Z APX AND GRB SOUNDINGS. NO SURPRISE THAT THE LEADING EDGE OF SCT SHRA/TSRA OVER CENTRAL WI HAS SHOWS SOME DIMINISH IN INTENSITY AS IT MOVES NE TOWARD THE SFC HIGH CENTER. HOWEVER...EXPECT LOW LEVELS WILL MOISTEN QUICKLY DURING THE MORNING WITH THE RAPID APPROACH OF THE WARM FRONT. SFC DWPTS HAVE ALREADY RISEN INTO THE MID 40S ACROSS PORTIONS OF WI AS HIGHER THETA-E VALUES ADVECT INTO THIS REGION. THETA-E WILL CONTINUE TO INCREASE THROUGHOUT THE DAY...BUT AREA OF MAX THETA-E WILL STAY TO THE W OVER THE UPPER MISSISSIPPI VALLEY UNTIL LATE AFTERNOON/EARLY EVENING WHEN THE 50 KT 850 MB JET MAX MOVES ACROSS THE CWA. MODEL CAPES INCREASE TO AROUND 2000-3000 J/KG BY 18Z ACROSS SRN SECTIONS OF THE CWA...AND THEN SPREAD NORTHWARD INTO THE REST OF THE CWA LATE IN THE DAY. 850-500 MB SHEAR WILL BE SUFFICIENT TO SUPPORT SUSTAINABLE UPDRAFTS WITHIN CONVECTION THAT DEVELOPS. CERTAINLY THINK SVR TSRA POTENTIAL EXISTS...ESPECIALLY DURING PEAK HEATING OF LATE AFTERNOON AND EARLY EVENING. WILL KEEP SCATTERED SHRA/TSRA IN THE FORECAST FOR ALL ZONES TODAY...AND CLOSELY MONITOR ANY STORMS THAT DO DEVELOP FOR SVR POTENTIAL. TONIGHT...HIGHLY UNSTABLE ENVIRONMENT CONTINUES INTO THIS EVENING BEFORE COLD FRONT PASSES THRU THE CWA OVERNIGHT. SFC LOW RIDES ALONG THE WARM FRONT...REACHING UPR MI BY 00Z FRI AND THEN MOVING NE OF THE STATE OVERNIGHT. SVR WX THREAT WILL CONTINUE AND MAY EVEN BE HEIGHTENED BY INCREASING LOW LEVEL CONVERGENCE PROVIDED BY THE SFC LOW AND COLD FRONT. WILL MAINTAIN LIKELY POPS FOR ALL ZONES TONIGHT AND CONTINUE TO MONITOR THE SITUATION CLOSELY AS THE EVENT UNFOLDS. FRIDAY THROUGH SATURDAY...COLD CANADIAN HIGH PRES MOVES INTO THE REGION...DROPPING TEMPS BACK TO MORE SEASONAL VALUES. STILL LOOKS LIKE A DRY PERIOD...BUT EXPECT BKN-OVC CLOUDS WILL LINGER OVER THE REGION AS AMPLE LOW LEVEL MOISTURE REMAINS IN PLACE. NO CHANGES MADE TO THE REST OF THE FORECAST. THANKS TO DTX AND GRR FOR COORDINATION. .APX...NONE. EME
