AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
431 AM EDT WED JUN 23 2010
.SYNOPSIS...
00Z RAOBS/LATEST WV IMAGERY AND RUC ANALYSIS SHOW BROAD UPR RDG OVER
THE SCNTRL CONUS EXTENDING INTO THE GRT LKS. SEVERAL SHRTWVS OF NOTE
ARE MOVING W-E ON THE NRN PERIPHERY OF THIS RDG. THE FIRST IS
CROSSING ONTARIO AND INTERACTED WITH AN AXIS OF HIER H85 DWPT TO
TRIGGER A FEW TS THAT DROPPED NICKEL-SIZED HAIL AT A FEW SPOTS IN
GOGEBIC/ONTONAGON COUNTIES LAST EVNG. AT 04Z...SOME REMNANT SHRA ARE
TENDING TO WEAKEN WITH LOSS OF DIURNAL HEATING AS THEY MOVE INTO
MORE CAPPED ENVIRONMENT SHOWN ON THE 00Z GRB RAOB AND IMPACTING
AREAS MAINLY NEAR THE WI BORDER. ANOTHER STRONG SHRTWV IS LOCATED
NEAR LK WINNIPEG AND BRINGING SOME SHRA/TS TO AREAS OF NW ONTARIO
JUST N OF THE MN BORDER. THIS SHRTWV IS SUPPORTING A COLD FNT THAT
SHOWS UP BEST AT H85 AND WHICH DIFFERENTIATES 00Z H85 TEMPS APRCHG
20C AT MNM FM 12C READINGS OVER LK WINNIPEG. ANOTHER STRONG SHRTWV
LIFTING ENEWD FM THE CNTRL ROCKIES INTO THE NCNTRL PLAINS IS CAUSING
QUITE A BIT OF CONVECTION OVER SDAKOTA...NEBRASKA...AND IOWA NEAR
H85 WARM FNT AND 00Z H85 DWPT OF 21C OBSVD AT OMAHA. MORE RECENTLY...
THE SHRA/TS TO THE SW HAVE EXPANDED INTO THE SW COUNTIES WHERE MUCAPE
ARE AOA 1000 J/KG. GIVEN THE FAVORABLE EFFECTIVE LYR SHEAR
PROFILES... SPC OPTED TO ISSUE A SEVERE THUNDERSTORM WATCH FOR THE
CWA NEAR THE WI BORDER W OF MNM COUNTY.
&&
.DISCUSSION...
MAIN FCST CONCERNS THIS PACKAGE INCLUDE SHRA/TS CHCS ASSOCIATED WITH
THE SHRTWVS NEAR LK WINNIPEG AND MOVING INTO THE NCNTRL PLAINS.
FOCUS FOR LATE TNGT THRU THU NGT SHIFTS TO DRYING TREND EXPECTED AS
HI PRES BLDS INTO THE UPR GRT LKS BEHIND COLD FROPA ASSOCIATED WITH
LK WINNIPEG SHRTWV. PCPN CHCS BCM A CONCERN AGAIN ON FRI WITH A
QUICK PROGRESSION OF SHRTWVS IN FAST ZONAL FLOW ALF.
TDAY...AS HAS BEEN THE CASE FOR THE LAST SEVERAL MODEL CYCLES...THE
GFS HAS BEEN SUFFERING CONVECTIVE FEEDBACK ISSUES AND SLIDING A
STRONGER SFC LO INTO THE FA THIS AFTN WITH AN AXIS OF HEAVY RA. THE
00Z RUN HAS TENDED TO BACK OFF A BIT FM EARLIER PROJECTIONS BUT
STILL FCSTS A DEEPER SFC LO TOO FAR N. PREFER THE CONSENSUS OF THE
OTHER GUIDANCE WHICH SHOWS THE BULK OF THE PCPN ASSOCIATED WITH
SHRTWV NOW IN THE NCNTRL PLAINS REMAINING TO THE S CLOSER TO WARM
FNT REINFORCED BY EXISTING CONVECTION TENDING TO SHIFT E THRU SRN
MN/WI. MSTR INFLUX IN ADVANCE OF LATE DAY COLD FROPA ASSOCIATED WITH
PASSAGE OF THE LK WINNIPEG SHRTWV EWD THRU ONTARIO JUST N OF LK SUP
SHOULD BE THE PRIMARY MECHANISM FOR PCPN PRODUCTION OVER THE FA.
WHILE DEEPER MSTR WL LIKELY REMAIN TO THE S OF THE FA AND CLOSER TO
H85 WARM FNT ACRS SCNTRL WI...THE 00Z NAM STILL SHOWS PWAT INCRSG TO
AOA 2 INCHES OVER THE SRN TIER THIS AFTN (ALMOST 200 PCT OF NORMAL)
WITH H85 DWPTS INCRSG TO ARND 14C. SINCE THE NAM ALSO SHOWS INCRSG
UPR DVGC/DEEP LYR QVECTOR CNVGC IN RRQ OF 110KT H3 JET MAX OVER
ONTARIO AT THE SAME TIME AND THIS GENERAL SCENARIO IS CONSISTENT
WITH THE FCST FM THE 12Z/00Z CNDN MODELS AND 00Z LOCAL
WRF-ARW...OPTED TO BUMP POPS UP TO LIKELY OVER THE SRN TIER THIS
AFTN. EXPECTED HI PWAT/DEEP HI RH...HI FRZG LVL AT 13.5K FT...AND
LGT FAIRLY UNIDIRECTIONAL SW FLOW FCST FM SFC-H5 SHOWN ON NAM FCST
SDNGS FOR THE SCNTRL WOULD INDICATE THE POTENTIAL FOR HEAVY RA
THERE... ESPECIALLY IF NAM FCST AXIS OF SHARPER H85-7 FGEN VERIFIES
OVHD TO PROVIDE A SHARPER LLVL CNVGC MECHANISM. TAPERED POPS OFF TO
THE N WHERE NAM SHOWS DRIER MID LVL AIR IN THE FASTER MID LVL FLOW
ON THE SRN FLANK OF SHRTWV TRACK THRU ONTARIO. OTRW...THE INFLUX OF
MSTR/ MORE CLD COVER WL HOLD MAX TEMPS LOWER THAN YDAY. EXPECT THE
HIEST TEMPS OVER THE INTERIOR W WHERE MID LVL DRYING WL ALLOW AT
LEAST PARTIAL SUNSHINE.
ALTHOUGH GUIDANCE INDICATES A REINFORCING COLD FNT MAY CROSS THE CWA
OVERNGT FOLLOWING WITH PASSAGE OF THE NCNTRL PLAINS SHRTWV THRU
WI...THIS FROPA WILL OCCUR AFT DIURNAL HEATING HAS WANED AND IN THE
PRESENCE OF LARGER SCALE LLVL DRY ADVCTN BEHIND THE AFTN FROPA.
MAINTAINED GOING SCHC POPS IN THE EVNG BEFORE IMPACT OF DIURNAL
COOLING AS WELL AS DNVA IN THE WAKE OF SHRTWV PASSAGE WL REALLY
REDUCE PCPN CHCS.
THU SHOULD BE A VERY PLEASANT DAY WITH SFC HI PRES DOMINATING UNDER
CONFLUENT WNW FLOW ALF EVEN THOUGH MOST OF THE MODELS INDICATE THERE
MAY BE AN INCRS IN MID/HI CLD LATER IN THE DAY OVER THE W ASSOCIATED
WITH A QUICK MOVING DISTURBANCE APRCHG IN THE WNW FLOW ALF. WITH H85
TEMPS PEAKING NEAR 10C...EXPECT MAX TEMPS AWAY FM LK MODERATION TO
REACH THE MID 70S. NW H925 FLOW THRU THE DAY SHOULD MAXIMIZE LK
MODERATION OFF LK SUP BUT MINIMIZE THE INFLUENCE OF LK MI.
ON THU NGT...THE 00Z GFS/UKMET ARE MOST PROGRESSIVE WITH NEXT
DISTUBANCE AND ASSOCIATED ISENTROPIC ASCENT ON THE 300-305K SFCS IN
THE RETURN SW FLOW BTWN THIS DISTURBANCE AND THE DEPARTING HI CENTER
TO THE E. SINCE GOING FCST IS DRY AND THERE IS MUCH DISAGREEMENT ON
TIMING/TRACK OF THESE DISTURBANCES IN TRICKY QUICK ZONAL FLOW ALF...
WL MAINTAIN CONTINUITY WITH PREVIOUS DRY FCST FOR NOW. EXPECT THE
LOWEST MIN TEMPS OVER THE E FARTHEST FM ANY APRCHG DISTURBANCE AND
CLOSER TO DEPARTING SFC HI.
GIVEN THE SPREAD IN FCST SCENARIOS AS TO THE TIMING/TRACK OF SHRTWVS
THAT MIGHT IMPACT THE FA OVER THE WEEKEND...MADE FEW CHGS TO THE
GOING FCST FOR NOW.
&&
.AVIATION /FOR THE 06Z TAF ISSUANCE/...
FOG WILL RETURN TO KCMX AREA DURING THE EARLY MORNING HOURS...THEN
IFR/LIFR CONDITIONS IN FOG SHOULD PERSIST THROUGH THE REST OF THE
NIGHT UNDER LIGHT/CALM WINDS. AS WINDS BECOME LIGHT W TO NW LATER IN
THE NIGHT...FOG COVERING THE WRN PORTION OF THE LAKE WILL ADVECT UP
THE KEWEENAW...KEEPING LIFR CONDITIONS IN PLACE. OPTED TO BRING
IMPROVEMENT TO VFR BY AFTN...BUT IF WINDS REMAIN W TO NW RATHER THAN
VEERING MORE NRLY...FOG/STRATUS AND IFR CONDITIONS COULD PERSIST
WELL INTO THE AFTN.
AT KSAW...EXPECT FOG TO DEVELOP OVERNIGHT...BUT WITH HIGH CLOUDS
SPREADING OVERHEAD AND THICKENING...RADIATIONAL FOG SHOULDN'T BECOME
TOO THICK. THUS...ONLY DROPPED CONDITIONS TO IFR. IMPROVEMENT TO VFR
SHOULD OCCUR AROUND MID MORNING. EXPECT GROWING CLUSTERS OF
CONVECTION OVER THE PLAINS TO CONSOLIDATE INTO LARGE CONVECTIVE
COMPLEX THAT SHOULD AFFECT A GOOD PORTION OF UPPER MI DURING THE
DAY. ASSUMING THIS OCCURS...OPTED FOR SHRA AND POTENTIALLY HVY RAIN
TO AFFECT KSAW IN THE AFTN. SOME THUNDER POSSIBLE...BUT MUCH BETTER
INSTABILITY WILL BE FARTHER S. NRLY UPSLOPING WIND DURING PCPN EVENT
SHOULD RESULT IN CONDITIONS FALLING TO IFR...POSSIBLY LOWER. STRATUS
AND MVFR CONDITIONS AT BEST WILL LIKELY LINGER INTO THE EVENING
AFTER THE PCPN ENDS.

.MARINE /FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE/...
DENSE FOG ADVISORY FOR MUCH OF LAKE SUPERIOR CONTINUES FOR TODAY
GIVEN HIGH SURFACE DEWPOINTS AND LIGHT WINDS OVER CHILLY LAKE WATERS
AS WELL AS SURFACE AND SHIP OBSERVATIONS INDICATING VERY LOW
VISIBILITIES. THE FOG WILL NOT TOTALLY CLEAR UNTIL A LOW PRESSURE
TROUGH PASSES LATE THIS AFTERNOON AND DRIER AIR MOVES OVER LAKE
SUPERIOR. OTHERWISE...WINDS WILL BE AOB 20 KNOTS THROUGH THIS
FORECAST PERIOD WITH RELATIVELY WEAK PRESSURE GRADIENT AND HIGH
STABILITY OVER THE CHILLY LAKE WATERS.
