Area forecast discussion, Jun 10, 4:41 AM CDT, 8 hours 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
441 AM CDT FRI JUN 10 2005

.DISCUSSION...FORECAST FOCUS IS TIMING AND EXTENT OF CONVECTION
FOR BALANCE OF THE WEEK.

IN THE SHORT TERM....ISOLATED THUNDERSTORMS OVERNIGHT FIRING JUST
NORTH OF DIFFUSE SFC WRM FNT THAT IS EXPECTED TO LIFT NWD TODAY...
AND AREA OF SFC MOISTURE CONVERGENCE ALONG INLAND REMAINS OF LAKE
BREEZE FNT. 850 MB WINDS ON REGIONAL PROFILERS SHOW WE ARE ON ERN
EDGE OF NOSE OF BETTER SRLY FLOW...WITH WEAK ISENTROPIC LIFT AIDING
IN ISOLATED CONVECTION.

TIMING AND PLACEMENT OF CONVECTION OVER THE NEXT FEW DAYS WILL
REMAIN TRICKY AS WEAK IMPULSES AND MCV/S LIFT ACROSS RGN ON SW FLOW
AHEAD OF UPR LOW OVER NRN MT. CURRENT SHRT WV OVER NWRN IA/SWRN MN IS
EXPECTED TO STAY TO OUR WEST WITH ULD ASSOC WITH UPR JET MAX CENTERED
OVER NRN PLAINS...BUT BOUNDARIES FROM DYING THUNDERSTORMS APPROACHING
FROM THE WEST WILL INTERACT WITH DESTABILIZING AIRMASS OVER RGN WITH
AFTERNOON CAPES IN RANGE OF 1200 TO 1500 J/KG TO TRIGGER SCT
AFTERNOON TSTMS.

WINDS UP THRU COLUMN ARE WEAK...0-6 KM BULK SHEAR VALUES BELOW 30 KTS
TODAY...BUT SOME LOW-LVL VEERING AND SLIGHT INCREASE IN WIND
SPEEDS WITH HEIGHT COULD PRODUCE SOME BRIEF ORGANIZATION AND A
SLIGHT RISK OF HAIL AND GUSTY WINDS FROM A FEW OF THE STORMS THAT
DEVELOP THIS AFTERNOON...JUST AS IN THE PAST FEW DAYS.

BETTER CHC FOR MORE WIDESPREAD THUNDERSTORMS COMES SATURDAY AS MT LOW
BECOMES AN OPEN WAVE AS IT EJECTS EWD AHEAD OF SECOND LOW OFF PAC NW
COAST COMING ASHORE. LOW LVL FLOW SHIFTS OVER STATE WITH UPR
DIVERGENCE AND BETTER DYNAMICS AIDING LARGE SCALE ASCENT OVER RGN.
CONVECTIVE INITIATION WILL AGAIN BE DETERMINED BY LOCALIZED
BOUNDARIES...BUT MORE OF CWA SHOULD SEE TSTMS SAT.

.MKX WATCHES/WARNINGS/ADVISORIES...NONE.
