MESOSCALE DISCUSSION 0397

NWS STORM PREDICTION CENTER NORMAN OK

0451 PM CDT SUN APR 10 2011

AREAS AFFECTED...NRN LWR MI

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 102151Z - 102315Z

TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE THREAT THAT

COULD REQUIRE A WW WITHIN THE NEXT HOUR OR TWO.

STORMS HAVE RECENTLY INTENSIFIED WITHIN A ZONE OF LARGE-SCALE ASCENT

ASSOCIATED WITH LOWER/MID TROPOSPHERIC WARM ADVECTION NOW SPREADING

ACROSS UPPER LAKE MICHIGAN...TOWARD THE SURFACE WARM FRONTAL ZONE

ACROSS NORTHERN LOWER MICHIGAN. FORECAST SOUNDINGS SUGGEST THAT

INHIBITION REMAINS CONSIDERABLE FOR BOUNDARY LAYER BASED PARCELS

ALONG THE WARM FRONT. HOWEVER...AUGMENTATION OF STORMS/STORM

DEVELOPMENT DOES NOT SEEM OUT OF THE QUESTION...AS APPROACHING

FORCING INTERACTS WITH THE FRONT LATE THIS AFTERNOON/EARLY EVENING.

GIVEN VERY FAVORABLE WIND PROFILES...SUPERCELLS WITH A RISK FOR

TORNADOES APPEAR POSSIBLE BY 23-00Z.

POSSIBLE WW. AN INITIAL THREAT OF DISCRETE SUPERCELLS CAPABLE OF

LARGE HAIL...DMGG WINDS AND PERHAPS TORNADOES CAN BE EXPECTED.

UNCERTAINTY STILL EXISTS WITH REGARDS TO INITIATION OVER PORTIONS OF

MO...AS A WEAK UPPER WAVE OBSERVED ON WV IMAGERY OVER CNTRL IA/NRN

MO WOULD IMPLY SUBSIDENCE IN ITS WAKE. HOWEVER...21Z SOUNDING AT

SPRINGFIELD SUGGESTS THAT CONVECTIVE INHIBITION HAS NEARLY

ERODED...WITH 5 DEGREE C COOLING AT 850/700 MB SINCE 12Z AND

MOISTENING OF LOW LEVELS. VISIBLE SATELLITE IMAGERY REFLECTS AN

AGITATED CU FIELD ALONG A DRYLINE THAT HAS MIXED EWD INTO CNTRL

Which direction do you think cells in this area will move? NE or E? If they move NE, SE Wisconsin might have a shot, but if east, we will be in a storm hole tonight.

The frontal boundary is driving East watching the fine line, but the upper level winds are screaming out of the southwest so storm relative motion I think would be mainly NE or ENE. Some scattered shower echoes starting to show up from West of Dubuque to West and South of Iowa City now too. I don't know if its really ready to explode in Eastern Iowa just yet. Think we might have just enough capping still in place choking off the updrafts a bit.

NORTHERN BENZIE COUNTY IN NORTHERN LOWER MICHIGAN...

LEELANAU COUNTY IN NORTHERN LOWER MICHIGAN...

QUARTER SIZE HAIL...AND

DAMAGING WINDS IN EXCESS OF 60 MPH.

on a sidenote, the temp difference is more then 30 degrees in a 20 mile span because of a lake breeze over here by me.
