Area forecast discussion, May 30, 4:17 AM EST, 3 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 517 AM EDT MON MAY 30 2011 .SYNOPSIS... WSW UPPER LEVEL FLOW OVR UPR LAKES THIS MEMORIAL DAY MORNING BTWN RIDGE OVR THE SOUTHEAST UNITED STATES AND DEEP TROUGH OVR THE ROCKIES. NARROW BAND OF WEST-TO-EAST CONVECTION INITIATED LAST EVENING INTO THE OVERNIGHT HOURS NORTH OF WELL-DEFINED H85 WARM FRONT FM DAKOTAS INTO CNTRL WISCONSIN. RIBBON OF H7 FGEN INTERACTED WITH ADVECTION OF ELEVATED INSTABILITY TO THE SOUTH TO GENERATE A LOT OF LIGHTNING OVR THE AREA. THREAT OF CONVECTION OVR THE AREA TODAY UNTIL H85 FRONT LIFTS NORTH OF UPR MICHIGAN RESULTING IN INCREASING CAPPING. SFC WARM FRONT WELL UPSTREAM FM CNTRL IOWA INTO NORTHERN ILLINOIS IS FCST TO REACH CWA AND LIFT INTO NW ONTARIO... BUT THIS WILL NOT OCCUR UNTIL TONIGHT. ATTN THEN TURNS TO LEAD TROUGH PASSAGE/PSEUDO DRYLINE TUESDAY AFTN. STILL LOOKS LIKE A RISK OF STRONG STORMS AS THIS BOUNDARY PUSHES INTO THE WARM AND HUMID AIRMASS THAT DEVELOPS THROUGH TONIGHT. PRIMARY COLD FRONT SWINGS THROUGH TUESDAY NIGHT LEADING TO WINDY/DRIER AND MUCH COOLER CONDITIONS ON WEDNESDAY. HIGH PRESSURE BRIEFLY BUILDS ACROSS... BUT YET ANOTHER WARM FRONT FCST TO LIFT INTO THE AREA LATE THIS WEEK WITH MORE SHRA/TSRA CHANCES AT THAT POINT. && .DISCUSSION... H7 BOUNDARY LIT UP WITH CONVECTION AND NOW H85 FRONT IS DOING LIKEWISE WITH TSRA LIFTING INTO NORTHERN WI. MEANWHILE...A MORE FOCUSED AREA OF SHRA/TSRA TIED TO SHORTWAVE IN SW FLOW ALOFT ARE AFFECTING EASTERN SD INTO SOUTHERN MN. PROBABLY WILL SEE WAVES OF CONVECTION ADVECT AND/OR DEVELOP ACROSS THE AREA UNTIL PASSAGE OF H85 FRONT THIS AFTN. ANY TSRA COULD PRODUCE AT LEAST SMALL HAIL TODAY WITH MUCAPES 500-1000 J/KG ADVECTING IN FM THE SOUTH AND AS EFFECTIVE SHEAR (1-6KM) IS UP TO 50 KTS. SINCE SFC WARM FRONT IS SOUTH OF CWA UNTIL LATE AFTN IN THE FAR WEST CWA AND THIS EVENING ELSEWHERE...E/SE WINDS IN LOW LEVELS WILL HELP SUSTAIN BKN LOW CLOUDS OVR THE AREA AND ALLOW TEMPS STAY MAINLY IN THE MID 60S-MID 70S. EXCEPTIONS...IN THE WEST WHERE TEMPS REACH NEAR 80F THIS AFTN AND OVR THE KEWEENAW WHERE EAST WINDS OFF THE LAKE WILL LIKELY KEEP TEMPS IN THE 50S MOST OF THE DAY. COULD BE SOME FOG OVR KEWEENAW AND ALONG LK MICHIGAN WHERE WINDS ARE ONSHORE. AS UPR LOW OVR THE ROCKIES MOVES NORTHEAST TONIGHT...EXPECT SFC WARM FRONT TO LIFT TO THE NORTH OF THE CWA...AT LEAST OUT ACROSS LK SUPERIOR. THIS WILL PUT THE CWA WITHIN THE CAPPED WARM SECTOR. EXPECT VERY WARM AND POTENTIALLY BREEZY NIGHT. BOTH AFFECTS WILL BE EMPHASIZED NEAR LK SUPERIOR AS SRLY WINDS AT H9 ARE FCST BTWN 40-50 KTS. ONLY A PORTION OF THESE WINDS SHOULD MIX DOWN SINCE PROFILE IS VERY STABLE...BUT STILL SHOULD BE A BREEZY NIGHT NEAR THE LK SUPERIOR SHORE. WENT WITH NON-DIURNAL TEMPERATURE FCST AS TEMPS MAY RISE THROUGH THE NIGHT IN THE NORTH ONCE WARM FRONT MOVES THROUGH. CERTAINLY POSSIBLE THAT SOME LOCATIONS IN THE WESTERN AND NCNTRL CWA MAY SEE READINGS FLIRTING WITH 70F FOR A MAJORITY OF THE NIGHT. KEPT SMALL CHANCES FOR SHRA/TSRA OVR THE FAR WEST CWA LATE...BUT FOR THE MOST PART STRONG CAPPING WILL HOLD...PROHIBITING PCPN FM OCCURRING. SVR WEATHER THREAT STILL IS THERE FOR TUESDAY AS LEADING SFC-H85 TROUGH SWEEPS THROUGH DURING THE AFTN. WARM SECTOR WILL BE UNSTABLE AHEAD OF THE FRONT...WITH SFC/ML CAPES 1000-1500 J/KG. FCST SOUNDINGS INDICATE STOUT CAPPING INITIALLY IN THE DAY WITH CINH VALUES OVR 100 J/KG. ARRIVAL OF STRONGER HEIGHT FALLS IN THE AFTN ALONG WITH MOISTURE CONVERGENCE ALONG TROUGH SHOULD BE ENOUGH TO BREAK THE CAP AND LEAD TO CONVECTIVE DEVELOPMENT. STRONG WINDS ALOFT LEAD TO QUITE STRONG 0-6KM DEEP LAYER SHEAR VALUES POSSIBLY OVR 60 KTS IN THE AFTN. DISCRETE SUPERCELLS LIKELY WITH POTENTIAL ALSO FOR BOW ECHOS/DAMAGING WINDS AS THERE IS FAVORABLE LOW-LEVEL SHEAR AS WELL. SPC HAS MOST CWA IN SLIGHT RISK WITH POTENTIAL FOR SIG SEVERE...WHICH SEEMS VERY APPROAPRIATE. DEFINITELY A DAY TO KEEP AN EYE TO THE SKY WITH THE POTENTIAL FOR SEVERE STORMS. FRONT AND SHRA/TSRA PUSH OUT OF THE EASTERN CWA TUESDAY EVENING. MODELS STILL ON TRACK FOR A BREEZY AND COOLER DAY ON WEDNESDAY. SOME WIND HEADLINES MAY BE NEEDED FOR KEWEENAW WITH STRONG WINDS FCST AT 925-850MB. FOR NOW...EXPECT GUSTS TO 45 MPH ON WEDNESDAY. GIVEN THE STRONG/GUSTY WINDS...WILL CONTINUE TO WATCH POTENTIAL FOR NEAR CRITICAL FIRE WX CONDITIONS ON WEDNESDAY AS TEMPS INLAND RISE INTO THE LWR 70S AND HUMIDITY VALUES FALL BLO 30 PCT. NEXT ISSUE WILL BE ARRIVAL OF ANOTHER WARM FRONT LATER THURSDAY INTO THURSDAY NIGHT AND LINGERING INTO FRIDAY. ANOTHER COUPLE ROUNDS OF SHRA/TSRA EXPECTED WITH A POTENTIAL FOR STRONG STORMS YET AGAIN. && .AVIATION /FOR THE 06Z TAF ISSUANCE/... BAND OF SHRA/ISOLD TS HAS LIFTED N OF SAW BUT WL LIKELY IMPACT CMX EARLY IN THE FCST PERIOD. MORE SHRA/TS MAY DVLP TO THE SW TNGT AND IMPACT BOTH SITES THRU SUNRISE...BUT CONFIDENCE ON TIMING IS TOO LO TO PROVIDE SPECIFIC TIMES. EVEN THROUGH THERE WAS SOME RA EARLIER... THE LLVLS ARE TOO DRY PER NEARBY 00Z RAOBS TO ALLOW FOR ANY LO CLD/ FOG. SO VFR CONDITIONS SHOULD PREDOMINATE. AS WARM FNT TO THE SW LIFTS SLOWLY TOWARD UPR MI TODAY AND THICKNESS OF COOL WEDGE DECREASES...EXPECT SOME LOWER CLDS PRESENT AHEAD OF THIS BNDRY TO BRING AT LEAST MVFR CIGS. ONCE THE WARM FNT PASSES THE AREA THIS EVNG...EXPECT THE LO CLDS TO GIVE WAY TO VFR CONDITIONS AND A STEADY S WIND. BUT FAIRLY HI LLVL STABILITY BLO STRENGTHENING NOCTURNAL LLJ WL RESULT IN LLWS. && .MARINE /FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE/... FOG WILL CONTINUE TO DEVELOP TODAY INTO TONIGHT ON LAKE SUPERIOR AS GREATER LOW LEVEL MOISTURE MOVES INTO THE REGION WITH LOW PRESSURE MOVING INTO THE DAKOTAS AND A WARM FRONT APPROACHING LAKE SUPERIOR...ENE WINDS WILL STRENGTHEN TO AROUND 25 KT ACROSS THE WEST END OF LAKE SUPERIOR. HOWEVER...THE STRONGEST WINDS APPEAR TO BE TUE NIGHT THROUGH WED BEHIND A COLD FRONT THAT MOVES ACROSS THE AREA WITH WRLY GALES DEVELOPING. THERE IS STILL SOME UNCERTAINTY ON THE AMOUNT OF STABILITY WITH THE MARINE LAYER AND THE IMPACT ON WIND SPEEDS. HOWEVER...ENOUGH COLD ADVECTION IS EXPECTED SO THAT AT LEAST LOW END GALES SEEM LIKELY. && .MQT WATCHES/WARNINGS/ADVISORIES... UPPER MICHIGAN... NONE. LAKE SUPERIOR... NONE. LAKE MICHIGAN... DENSE FOG ADVISORY UNTIL 8 AM EDT TUESDAY FOR LMZ221-248-250. && SYNOPSIS...JLA DISCUSSION...JLA AVIATION...KC MARINE...JLB
