AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
615 AM EDT MON JUL 18 2011

.DISCUSSION...

THE WEAK COLD FRONT LOOKS TO BE SLIDING IN ON SCHEDULE...WITH A LINE
OF SHOWERS...AND A FEW THUNDERSTORMS SITUATED OVER NORTHERN AND
CENTRAL LAKE SUPERIOR AT 10Z. GIVEN THE ALL AROUND WEAK PRESSURE
FIELD THE EXACT LOCATION OF THE FRONT IS DIFFICULT TO FIGURE. WILL
CONTINUE TO PLAY UP SCATTERED TO ISOLATED SHOWERS AND EMBEDDED
THUNDERSTORMS SINKING SOUTH OF THE ARE THIS MORNING...WITH ANOTHER
ROUND OF POP UP SHOWERS OR THUNDERSTORMS ON THE MERGING LAKE BREEZES
OF LAKE MICHIGAN AND LAKE SUPERIOR TOWARDS THE AFTERNOON HOURS
/MAINLY OVER SOUTH CENTRAL AND EASTERN UPPER MI/.

SOME...ALBEIT MINIMAL RELIEF FROM THE HUMIDITY CAN BE FIGURED AS A
RESULT OF THE PASSAGE OF THE WEAK COLD FRONT. A FEW DEW POINTS IN
THE MID TO UPPER 50S CAN CURRENTLY BE FOUND OVER SOUTHERN ONTARIO.
EVEN WITH HIGH TEMPERATURES /DEPENDING ON LINGERING CLOUD COVER AND
SHOWER ACTIVITY/ ARE FIGURED TO TOP OUT NEAR 90 DEGREES ONCE AGAIN
OVER INTERIOR WESTERN PORTIONS OF UPPER MICHIGAN THIS AFTERNOON. THE
RESULT SHOULD BE APPARENT TEMPS /HEAT INDEX VALUES/ REMAINING IN THE
MID TO UPPER 90S THIS AFTERNOON. EVEN THOUGH SLIGHTLY WARMER SFC
TEMPS ARE EXPECTED TUESDAY AS HIGH PRESSURE DOMINATES THE
AREA...LOWER DEW POINTS IN THE MID TO UPPER 60S SHOULD RESULT IN
SIMILAR HEAT INDEX READINGS AS TODAY. WENT AHEAD AND ISSUED AN SPS
TO DISCUSS THE HOT AND HUMID CONDITIONS LINGERING THROUGH THE ENTIRE
WORK WEEK.

SOUTHERLY WINDS WILL AGAIN TAKE HOLD TUESDAY NIGHT AS THE SFC HIGH
EXITS EASTWARD. FOR WEDNESDAY A WARM FRONT AHEAD OF THE NEXT LOW
OVER THE NORTHERN TO CENTRAL PLAINS WILL ASSIST IN PULLING 70S DEW
POINTS BACK OVER UPPER MICHIGAN...AS THE MID LEVEL RIDGE EDGES BACK
ACROSS THE UPPER GREAT LAKES. THIS SHOULD BE ENOUGH TO BRING HEAT
INDEX VALUES BACK INTO THE 100 TO 105 RANGE FOR BOTH WEDNESDAY AND
THURSDAY /UNLESS LATE MORNING TO MID AFTERNOON CONVECTION DEVELOPS/.
&&

.AVIATION /FOR THE 06Z TAF ISSUANCE/...

APPEARS THE CONVECTION IS JUST ABOUT OVER AS THE SHORTWAVE MOVES
THROUGH. WITH HOT AND MUGGY CONDITIONS CONTINUING...THE MAIN CONCERN
THIS PERIOD IS FOG...ESPECIALLY AT CMX...DUE TO ALREADY MOIST
AIR...LIGHT WINDS AND ADVECTION OFF THE LAKE...SO LIFR SEEMS TO BE
PRETTY CERTAIN. CHOSE TO GO MORE CONSERVATIVE ON VISIBILITY FOR SAW
AS WINDS ARE LIGHTER AND MORE VARIABLE...BUT LIFR OR EVEN VLIFR IS
STILL A POSSIBILITY AND PUT THAT IN TOWARDS SUNRISE. THEN VFR
CONDITIONS WILL RETURN BY LATE MORNING AT BOTH SITES AS SFC HEATING
MIXES THE FOG AND LOW STRATUS OUT.
&&

.MARINE /FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE/...

A HIGH PRESSURE RIDGE OVER THE UPPER GREAT LAKES WILL KEEP WINDS
BELOW 20KTS INTO WEDNESDAY. SOUTHWEST TO WEST WINDS COULD INCREASE
TO 25 KTS WED NIGHT INTO THURSDAY OVER WRN AND CENTRAL LAKE SUPERIOR
AS GRADIENT TIGHTENS BETWEEN ADVANCING TROUGH OVER ONTARIO AND THE
NRN PLAINS AND RIDGE DEPARTING TO THE EAST. ANOTHER RIDGE BUILDING
IN BEHIND THE TROUGH FOR THU NIGHT AND FRIDAY WILL BRING WINDS BACK
DOWN BLO 20 KTS. AREAS OF FOG WILL BE POSSIBLE FOR MUCH OF THE
PERIOD...AS WARM AND MOIST AIR MOVES NORTHEAST ACROSS LAKE SUPERIOR.
KEPT DENSE FOG ADVY IN EFFECT THROUGH TONIGHT OVER ALL OF THE OPEN
WATERS OF LAKE SUPERIOR.
