AREA FORECAST DISCUSSION...MESOSCALE UPDATE...
NATIONAL WEATHER SERVICE DULUTH MN
750 PM CDT FRI JUL 28 2006

.DISCUSSION...PER SATELLITE IMAGERY..SHORT WAVE RIDGING BETWEEN
DISTURBANCE OVER WRN LK SUPERIOR AND NEXT APPROACHING IMPULSE
CURRENTLY OVER ERN MONTANA APPEARS TO BE BUILDING INTO THE WRN
SECTIONS OF THE DLH CWA ATTM AS NOTED BY DECREASE IN TOWERING CU TO
THE W/SW OF KDLH IN PAST HOUR.  EXPECT CAPPING TO INCREASE FOR NEXT
FEW HOURS FROM W TO E ACROSS THE AREA..BUT WAA/FGEN ZONE WILL CONT
TO TRANSLATE EWD THRU WISCONSIN JUST ON DOWNSTREAM SIDE OF RIDGE
AXIS. ERGO..STORMS ARE EXPECTED TO PERSIST FOR SEVERAL MORE HOURS IN
OUR ERN CWA.  STORMS SHUD BECOME MORE ELEVATED WITH TIME..WITH MAIN
THREAT BEING NICKEL TO QUARTER SIZE HAIL.  SOME ECHO TRAINING ALSO
NOTED FROM NE DOUGLAS ACROSS BAYFIELD AND ASHLAND COUNTIES..AND WE
WILL MONITOR FLASH FLOOD POTENTIAL..BUT THIS APPEARS QUITE LOW DUE
TO BACKGROUND DRY CONDITIONS.

FOCI FOR ADDITIONAL INTENSE CONVECTIVE DEVELOPMENT APPEARS TO BE
CONSOLIDATING TO OUR WEST IN THE BIS-ABR-FAR AREA..JUST ON COOL SIDE
OF FRONTAL BOUNDARY WHERE INTENSE LLJ AXIS IS EXPECTED TO
DEVELOP/FOCUS OVER THE NEXT 3-5 HOURS. WE EXPECT MCS-GENESIS IN THIS
AREA ROUGHLY 03-07 UTC WITH SYSTEM THEN PROPAGATING EWD INTO DLH CWA
AFTER MIDNIGHT.  ALTHOUGH DEFINITELY NOT A CERTAINTY AT THIS
POINT..SYNOPTIC SET UP DOES APPEAR SOMEWHAT FAVORABLE FOR FORWARD
PROPAGATING SYSTEM AND ATTENDANT NOCTURNAL/EARLY MORNING HIGH WIND
THREAT..AND THIS WILL NEED TO BE MONITORED CLOSELY.
