AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
403 AM CDT MON JUL 7 2008

FORECAST FOCUS ON THUNDERSTORM CHANCES THROUGH TUESDAY.

LATEST WATER VAPOR IMAGERY INDICATED A SHORTWAVE TROUGH OVER THE
NORTHERN ROCKIES...WITH MAINLY ZONAL UPPER LEVEL FLOW DOWNSTREAM
OF THIS FEATURE. ONE AREA OF CONVECTION OCCURRING AHEAD OF THIS
FEATURE OVER THE DAKOTAS.

AT THE SURFACE...A WARM FRONT WAS LOCATED FROM NORTHERN NEBRASKA
EAST THROUGH CENTRAL IOWA AND CENTRAL ILLINOIS. OTHER AREAS OF
CONVECTION OCCURRING NEAR THIS BOUNDARY...OR WITH A LOW LEVEL JET
NOSE...OVER NORTHEAST NEBRASKA AND CENTRAL ILLINOIS BACK INTO
SOUTHEAST IOWA.

.SHORT TERM...TODAY THROUGH TUESDAY...

FORECAST APPEARS A BIT MORE CLEAR THAN YESTERDAY. SURFACE WARM
FRONT SHOULD ADVANCE NORTHEAST THROUGH SOUTHERN WISCONSIN THIS
MORNING. UPWARD VERTICAL MOTION WITH THIS FEATURE...AND MORE SO
WITH THE LOW LEVEL JET NOSE THIS MORNING...SHOULD RESULT IN
SHOWERS AND THUNDERSTORMS DEVELOPING AND MOVING OVER THE AREA.
ALREADY SEEING NEW DEVELOPMENT OVER CENTRAL AND EASTERN IOWA WITH
THESE FEATURES.

FORECAST SOUNDINGS SHOW THE 1000 J/KG OF CAPE IS ELEVATED. GIVEN
PRECIPITABLE WATER VALUES OF AROUND 1.80 INCHES AND SLOW MESO BETA
ELEMENTS VELOCITIES...LOCALLY HEAVY RAINFALL WOULD BE POSSIBLE
WITH ANY OF THE STORMS.

A BREAK IN THE CONVECTION IS POSSIBLE THIS AFTERNOON...AS WARM
SECTOR MOVES INTO THE AREA. CAPPING INVERSION POSSIBLE WITH THE
WARM SECTOR...WHICH WOULD ALSO LIMIT CONVECTIVE CHANCES. WILL KEEP
THE CHANCE WORDING FOR THIS AFTERNOON FOR NOW.

THE BEST CHANCE FOR THUNDERSTORMS STILL LOOKS TO BE TONIGHT...AS
COLD FRONT MOVES INTO THE REGION. SHORT TERM MODELS HINTING AT A
POSSIBLE MCS FORMING OVER MINNESOTA AND IOWA...MOVING NORTHEAST
INTO WISCONSIN OVERNIGHT. SOME QUESTION AS TO THE EXACT AREA THAT
WOULD BE AFFECTED BY THE MCS. IF AREA IS AFFECTED...HEAVY RAINFALL
WOULD AGAIN BE POSSIBLE GIVEN THE LOW MESO BETA ELEMENTS
VELOCITIES AND PRECIPITABLE WATER VALUES AROUND 2.00 INCHES. GIVEN
THE UNCERTAINTY WITH THE EXACT LOCATION OF THE MCS...WILL NOT
MENTION HEAVY RAIN IN THE FORECAST FOR NOW.

SEVERE WEATHER...MAINLY STRAIGHT LINE WINDS...WOULD ALSO BE
POSSIBLE GIVEN THE UNIDIRECTIONAL SHEAR VALUES OF UP TO 35
KNOTS...WITH MEAN LAYER CAPES OF UP TO 1500 J/KG. ONE NEGATING
FACTOR WOULD BE CAPPING INVERSION LIMITING SURFACE BASED STORMS.
STILL...INCREASING LOW LEVEL JET TO 40 KNOTS SHOULD TAP INTO
ELEVATED INSTABILITY.

COLD FRONT TO MOVE OUT OF THE AREA ON TUESDAY...BRINGING
CONVECTION CHANCES DOWN WITH IT AS THE DAY PROGRESSES.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...

HIGH PRESSURE WILL MOVE ACROSS THE REGION FOR TUESDAY NIGHT
THROUGH WEDNESDAY...BRINGING GENERALLY QUIET WEATHER. DEVELOPING
WARM FRONT AND WARM AIR ADVECTION MAY BRING SOME PRECIPITATION TO
THE AREA ON THURSDAY...AND IN THE FAR NORTHERN PORTIONS OF THE
AREA THURSDAY NIGHT. ADDED POPS FOR THESE PERIODS IN THE FORECAST.

THEN...A GOOD CHANCE FOR A WARMING TREND FOR FRIDAY AND
SATURDAY...WITH WARM AIR ADVECTION CONTINUING TO RAISE THE
1000/500MB THICKNESSES INTO THE UPPER 570S DKM RANGE.

&&

.AVIATION...

WEAK SURFACE BOUNDARY ACROSS CENTRAL WI WITH MAIN WARM FRONT
ACROSS IA AND CENTRAL IL. GENERAL WARM AIR ADVECTION IN SOUTHWEST
LOW LEVEL FLOW. AS MAIN SHORTWAVE MOVES ACROSS THE NORTHERN PLAINS
TODAY AND REACHES THE UPPER MISSISSIPPI VALLEY TONIGHT...THE LOW
LEVEL JET WILL INCREASE AND AN MCS IS EXPECTED TO MOVE ACROSS
SOUTHERN AND/OR CENTRAL WISCONSIN TONIGHT.

UNSTABLE AIRMASS WILL INCREASE ACROSS SOUTHERN WI WITH OCCASIONAL
SHOWERS AND SCATTERED THUNDERSTORMS TODAY. MORE THUNDERSTORMS
EXPECTED TONIGHT. AREAS OF MVFR CIGS WITH DEVELOPING CU THIS
MORNING...WITH MAINLY VFR THIS AFTERNOON...ALTHOUGH MVFR
CIGS/VSBYS WITH ISOLATED IFR CONDITIONS IN THUNDERSTORMS.
GREATEST SEVERE THUNDERSTORM THREAT TONIGHT.

&&

.MARINE...

WINDS MAY APPROACH SMALL CRAFT ADVISORY CONDITIONS TONIGHT...AS
SOUTHWEST WINDS INCREASE AHEAD OF A STRENGTHENING LOW OVER THE
UPPER GREAT LAKES BY TUESDAY MORNING. SCATTERED THUNDERSTORMS
TODAY...BUT MORE WIDESPREAD TONIGHT...WITH GREATEST WIND THREAT
IN THUNDERSTORMS TONIGHT.

&&

.MKX WATCHES/WARNINGS/ADVISORIES...
