URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 475
NWS STORM PREDICTION CENTER NORMAN OK
440 PM CDT WED JUL 14 2010

THE NWS STORM PREDICTION CENTER HAS ISSUED A
SEVERE THUNDERSTORM WATCH FOR PORTIONS OF

CENTRAL AND NORTHWEST IOWA
CENTRAL AND SOUTHERN MINNESOTA
EXTREME NORTHEAST NEBRASKA

EFFECTIVE THIS WEDNESDAY AFTERNOON AND EVENING FROM 440 PM UNTIL
1000 PM CDT.

HAIL TO 2.5 INCHES IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.

THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 60
STATUTE MILES EAST AND WEST OF A LINE FROM 35 MILES NORTH
NORTHWEST OF MINNEAPOLIS MINNESOTA TO 25 MILES SOUTH SOUTHWEST OF
STORM LAKE IOWA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU5).

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.

OTHER WATCH INFORMATION...CONTINUE...WW 473...WW 474...

DISCUSSION...THUNDERSTORM DEVELOPMENT IS EXPECTED TO PROCEED SWWD
ALONG THE SYNOPTIC FRONT ACROSS CENTRAL MN...AND ADDITIONAL STORM
DEVELOPMENT WILL OCCUR NEWD FROM ERN NEB TOWARD NW IA. INSTABILITY
IS STRONG ACROSS THE WATCH AREA...WHILE DEEP-LAYER VERTICAL SHEAR
WEAKENS FROM N TO S FROM MN INTO IA. THE NET RESULT IS AN
ENVIRONMENT SUPPORTIVE OF BOTH SUPERCELLS AND BOWING SEGMENTS. AN
ISOLATED TORNADO CANNOT BE RULED OUT GIVEN THE STRONG
INSTABILITY...BUT LARGE HAIL AND DAMAGING WINDS SHOULD BE THE
PRIMARY THREATS GIVEN THE SOMEWHAT VEERED LOW-LEVEL FLOW AND
STRAIGHT HODOGRAPH STRUCTURES.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 600. MEAN STORM
MOTION VECTOR 27035.

Radar signature near Merrillan, WI looks really impressive...

[Siberian Express]

Interesting to watch, that cell by Neillsville, WI was discrete with a definite hook, then it gets absorbed by the Meso squall line. Wish I had that 'fancy' radar software.

[OverlandHurricane]

I thought for sure that we were going to get a monster thunderstorm here on the northern flank of the Twin Cities. Instead, all we got was a capped out atmosphere. Wind has swung around to the west at around 10 MPH, and the dew point is sinking rapidly.

It was miserable marking out points at work today.
