607 PM CDT TUE AUG 18 2015

UPDATED AVIATION PORTION FOR 00Z TAF ISSUANCE

.SYNOPSIS...
ISSUED AT 318 PM CDT TUE AUG 18 2015

STRONG LATE-SUMMER STORM SYSTEM TO AFFECT THE AREA DURING THE NEXT
24 HOURS...THEN QUIETER WEATHER FOR THE LATTER PART OF THE WORK
WEEK AND THE START OF THE WEEKEND.

THE UPPER PATTERN HAS TRANSITIONED TO ONE WITH A DEEP UPR TROF OVER
THE N-C CONUS FLANKED BY RIDGING ALONG THE COASTS. THAT PATTERN
WL PERSIST FOR MUCH OF THE PERIOD THOUGH IT APPEARS THAT LATE IN
THE WEEK WE WL BEGIN TO SHIFT BACK TO THE HAVING A MID-CONTINENT
RIDGE AND TROFS NR THE COASTS.

THIS WL BE AN ACTIVE WX PATTERN AS A SERIES OF CYCLONES AND
ASSOCIATED FRONTAL SYSTEMS AFFECT THE AREA. THE FIRST CYCLONE WL
CROSS THE REGION EARLY...WITH ANOTHER PASSING THROUGH FARTHER TO
THE NW DURING THE WEEKEND. THOSE 2 SYSTEMS SHOULD GENERATE ENOUGH
PCPN TO RESULT IN ABV NORMAL AMNTS FOR THE PERIOD. SEASONABLY COOL
WX IS EXPECTED THE NEXT COUPLE DAYS...THEN TEMPERATURES WL RETURN
CLOSE TO SEASONAL NORMALS.
&&

.SHORT TERM...TONIGHT AND WEDNESDAY
ISSUED AT 318 PM CDT TUE AUG 18 2015

FRONTAL BOUNDARY REMAINS DRAPED JUST SOUTH OF WAUTOMA TO OSHKOSH
TO MANITOWOC LINE. TEMPERATURES WARMED INTO THE MIDDLE 70S TO
LOWER 80S OVER THE FOX VALLEY EAST TO KEWAUNEE AND MANITOWOC.
TO THE THE NORTH...TEMPERATURES ONLY WARMED INTO THE LOWER TO
MIDDLE 60S FROM WAUSAU TO ANTIGO. SCATTERED THUNDERSTORMS WERE
DEVELOPING ACROSS PORTIONS OF CENTRAL AND EAST-CENTRAL WISCONSIN
JUST NORTH OF THE WARM FRONT.

STRONG AUGUST STORM WILL MOVE NORTHWEST OF THE AREA TONIGHT AND
WEDNESDAY. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO OVERSPREAD
THE REGION THIS EVENING BEFORE TAPERING OFF AGAIN LATER TONIGHT.
A FEW OF THE STORMS COULD PRODUCE STRONG OR DAMAGING WIND GUSTS.
THE OCCLUDED FRONT WILL MOVE ACROSS THE REGION WEDNESDAY
MORNING...BRINGING ANOTHER CHANCE OF SHOWERS AND STORMS. IF THIS
LINE DOES DEVELOP...STRONG OR DAMAGING WIND GUSTS ARE POSSIBLE.

DID NOT STRAY FAR FROM GUIDANCE TONIGHT...WENT COOLER ACROSS THE
WEST AND SLIGHTLY WARMER ACROSS THE EAST FOR HIGHS ON WEDNESDAY.

.LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY
ISSUED AT 318 PM CDT TUE AUG 18 2015

THE STG CYCLONE WL TRACK ACRS WRN LAKE SUPERIOR WED NGT. PCPN IS
LIKELY TO LINGER INTO THE NGT...ESP ACRS THE NW PART OF THE FCST
AREA WHICH WL BE CLOSER TO THE UPPER CIRCULATION CENTER. SCT LGT
PCPN IS POSSIBLE FARTHER E.

THE SYSTEM WL BE PULLING AWAY FM THE AREA THU. SOME SCT LGT PCPN
COULD STILL LINGER IN THE NW PART OF THE AREA. TRENDED TOWARD THE
WINDIER GUIDANCE PRODUCTS AS FCST SOUNDINGS EXHIBIT LITTLE
DIRECTIONAL SHEAR IN LOW-LEVELS AND ANTICIPATE BEING ABLE TO MIX
INTO STRONGER WINDS ALOFT.

QUIET WX IS THEN EXPECTED FOR THE END OF THE WORK WEEK...AND
PROBABLY THE FIRST PART OF THE UPCOMING WEEKEND. ANOTHER FAIRLY
STG CYCLONE LOOKS TO AFFECT THE AREA DURING THE LATTER PART OF THE
UPCOMING WEEKEND. THAT SYSTEM WL TRACK FARTHER NW OF THE FCST
AREA...SO PCPN WL LIKELY BE CONCENTRATED INTO A SHORTER TIME
PERIOD...WHEN THE COLD FRONT CROSSES THE RGN. RIGHT NOW IT APPEARS
THAT WL HAPPEN IN THE SAT NGT/SUN TIME FRAME.

NO SIG CHGS TO THE EXTENDED FCST BASED ON A BROAD BLEND OF
GUIDANCE PRODUCTS.
