AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI

329 PM CDT SUN APR 10 2011

VERY SHORT TERM

LATE AFTERNOON THROUGH MONDAY. FORECAST

CONFIDENCE...MEDIUM

VERY WARM AND MOIST AIR MASS FOR EARLY APRIL IN PLACE ACROSS SRN WI

THIS AFTERNOON AHEAD OF APPROACHING STRONG LOW PRESSURE. WITH THE

WARM FRONT WELL TO THE NORTH ACROSS FAR NW WI AND THE WESTERN UPPER

PENINSULA OF MI...AND THE COLD FRONT STRETCHING FROM SE MN THROUGH

CENTRAL IA...THE FORECAST AREA IS RIGHT SMACK IN THE WARM SECTOR OF

THIS SYSTEM. MIXED LAYER CAPES HAVE INCREASED TO 1500-2000 J/KG AS

THE ATMOSPHERE CONTINUES TO DESTABILIZE. TONS OF SHEAR...WITH 0-6 KM

VALUES CURRENTLY 55-65 KTS...AND MAY INCREASE TO 75 KTS BEFORE

STORMS GET GOING. ATMOSPHERE REMAINS PRETTY CAPPED FOR THE

MOMENT...BUT APPROACHING JET STREAK SHOULD AID IN WEAKENING THE CAP

LATER THIS AFTERNOON. HIGH RES RAPID REFRESH AND LOCAL WRF MODEL

BRING STORMS INTO THE WEST BY 7 PM THIS EVENING...WITH THE

CONVECTION EXITING THE EAST BY MIDNIGHT OR SHORTLY THERE AFTER AS

THE COLD FRONT CLEARS SRN WI.

GIVEN THE SETUP...THE STORM MODE STILL LOOKS TO BE SUPERCELLS...WITH

GENERAL SCATTERED COVERAGE. DID NOT RAISE LIKELY POPS WITH DISCRETE

NATURE OF THE CELLS...BUT ENTIRE AREA AT RISK FOR SEVERE STORMS LATE

AFTERNOON THROUGH THE EVENING...THE BEST CHANCE ACROSS THE NW CWA

WHERE SPC IS MAINTAINING A MODERATE RISK FOR SEVERE STORMS. STRONG

AND LONG LIVED TORNADOES...LARGE HAIL...AND DAMAGING WINDS WILL ALL

BE THREATS WITH THESE STORMS.

Is the low going further north than expected? Thought the tornado threat was going to be further south into Illinois. Derechos likely to form further south?

There won't be a derecho because the energy is expected to split with time.

Since the energy is splitting the best dynamics is displaced further north than what was expected a day or two ago, thus making it harder to break the cap for areas in between and somewhat decreasing the severe weather potential. The storms that develop in Wisconsin will move up into Northern Lower Michigan and the UP.

The other part of the energy is expected to spawn more thunderstorms in the central/southern mississippi valley that will move E/NE.

I think you're talking about Julie Martin down in Rockford; they showed a map of the Dells when I turned the channel on, but then found out she was in Rockford. Unless they have another met in the Dells.
