What happened

The episode as NWS MPX wrote it up.

Windy conditions occurred in response to a deep low pressure center over Central South Dakota, combined with a large high pressure area over the Eastern Great Lakes. Some measured winds gusts of note include: 71 mph in Hanley Falls (Yellow Medicine County), 63 mph in Madison (Lac Qui Parle County), 59 mph in Canby (Yellow Medicine County), 60 mph in Appleton (Swift County), 68 mph four miles southwest of Belle Plaine (Scott County), 58 mph seven miles south of Starbuck (Pope County), 63 mph in Mankato (Blue Earth County), and 65 mph two miles WSW of New Prague (Le Sueur County). Scattered reports of trees, large branches, and power lines down throughout the region were reported. Additionally, strong winds ripped the roof off a repair shop in St. Clair. Shoreland Golf Course in St. Peter had so many downed trees they were forced to close for the day; the course superintendant said it was some of the worst damage he had ever seen. According to the Pope County Sheriff's office, an evergreen tree was knocked down over wires in Starbuck, a power pole was down on trees in Lowry, a shed was blown down in Cyrus, a power pole was toppled in Glenwood, and wires were down in Starbuck. According to the Mankato Free Press newspaper, several power lines blew over, and fallen trees blocked roads in the city of Mankato. Siding was ripped off a home in North Mankato. The State Patrol confirmed a recreational vehicle was overturned on Highway 22 about 5 miles north of Mankato. In New Prague, high winds toppled several trees and tree limbs, along with a power line, which affected customers northeast of the city.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
646 AM CDT SUN MAY 6 2007

.UPDATE...
HAVE ISSUED A FLOOD WATCH FOR AREAS ALONG A LINE FROM OLIVIA TO
FAIRMONT. BAND OF MODERATE TO HEAVY RAIN CONTINUES TO TRAIN OVER
THE WATCH AREA. SFC ANALYSIS SUGGESTS FRONTAL BOUNDARY DEVELOPING
ALONG THE MINNESOTA RIVER VALLEY AS DRY AIR FEEDS INTO LEADING
EDGE OF RAIN ALLOWING EVAPORATIVE COOLING TO TAKE PLACE AS
EVIDENCED BY CORRIDOR OF COOLER TEMPS WEDGED BETWEEN WARMER AIR
MASSES TO THE WEST AND EAST. LOCAL MORNING SOUNDING DATA SHOWS
SHARP INCREASE IN MOISTURE IN THE LOW LEVELS WITH NOTCH OF COOLER
TEMPS NOTED AT INTERFACE OF MOIST TRANSPORT AND REMAINING LOW
LEVEL DRY WEDGE. CONCERNED THAT LIFT WILL BE ENHANCED OVER THE
DEVELOPING BOUNDARY AND CONTINUE TO DEVELOP RAIN OVER THE NEXT
SEVERAL HOURS LEADING TO AMOUNTS BETWEEN 2 AND 5 INCHES IN SPOTS.

.PREV DISCUSSION... /ISSUED 426 AM CDT SUN MAY 6 2007/

DISCUSSION...
COMPLEX FORECAST WITH FOCUS ON THE FIRST FEW DAYS OF THE FORECAST
PERIOD. TO START...WILL KEEP WIND ADVISORY SOUTH OF A NEW ULM TO
MANKATO TO OWATONNA LINE THROUGH 9 AM. AREA OF PRESSURE RISES
CONTINUES TO DRIFT EASTWARD WITH WINDS AROUND 30 MPH WITH GUSTS TO
OVER 40 AT TIMES. NEXT ITEM IS BAND OF SHOWERS AND SCATTERED
THUNDERSTORMS LINED UP FROM NORTH TO SOUTH BEGINNING TO IMPACT THE
WESTERN CWA AS STRONGEST LLJ SHIFTS TO THE NORTH. EXPECT THAT THIS
BAND WILL CONTINUE TO AFFECT THE WESTERN CWA THROUGH MUCH OF THE
MORNING. BASED ON MOISTURE TRANSPORT TRYING TO GRADUALLY SHIFT A
BIT TO THE EAST...EXPECT THAT BAND WILL DO SO AS WELL. EASTWARD
PROGRESS WILL BE SLOW HOWEVER GIVEN THE EXTREMELY DRY AIR
STREAMING INTO THE EASTERN AND CENTRAL CWA ATTM THANKS TO STRONG
SFC HIGH PRES OVER EASTERN CANADA. THEREFORE HAVE A SHARP GRADIENT
IN PRECIP CHANCES FOR THE MORNING...WITH A GRADUAL INCREASE
EASTWARD TOWARD THE WI BORDER FOR THE AFTERNOON. SFC LOWS ACROSS
SODAK/NEBRASKA WILL WEAKEN TODAY AND DRIFT NORTHEAST TODAY. CROSS
SECTION ANALYSIS AND PWAT CHANGE SUGGEST THAT PRECIP WILL REACH
AREAS NEAR THE WI BORDER/TWIN CITIES METRO/ IN WAVES...BEGINNING
LATE THIS AFTERNOON...AND CONTINUING INTO THIS EVENING. INITIAL
BAND OF RAIN MAY PRODUCE THREE QUARTERS TO AN INCH OF RAIN ACROSS
WEST CENTRAL MN BEFORE NEXT ROUND SHIFTS EASTWARD POTENTIALLY
PRODUCING ANOTHER HALF TO ONE INCH OF RAIN ACROSS SOUTH CENTRAL MN
AND EAST CENTRAL MN LATE TODAY AND TONIGHT. ALSO A FIRE WEATHER
CONCERN FOR THE NORTHEAST WI CWA WHERE 20-30 MPH WINDS AND RH DOWN
TO AROUND 20 PERCENT WITH TEMPS AROUND 70 WILL CREATE VERY DRY
CONDITIONS. BASED ON COORDINATION WITH SURROUNDING OFFICES AND
AGENCIES...WILL MENTION DRY CONDITIONS IN FWF AND HWO.

SFC LOW WILL CONTINUE TO WEAKEN AND MOVE NORTHEAST ACROSS THE AREA
MONDAY BRINGING AND END TO THE PRECIP IN THE WEST BUT CONTINUING
CHANCES ACROSS THE EAST INTO MONDAY NIGHT. PRECIP CHANCES THROUGH
THE REST OF THE WEEK WILL BE TRICKY TO PIN DOWN AS UPPER LOW NOW
OVER THE FOUR CORNERS ATTEMPTS TO PUSH EASTWARD. TUESDAY EXPECTED TO
BE DRY HOWEVER...AS SFC HIGH SETTLES OVER THE AREA AND UPPER LOW IS
STILL A GOOD DISTANCE OFF. HAVE RETAINED SLIGHT POPS BEYOND THAT FOR
NOW. MILD WEATHER WILL CONTINUE WITH TEMPS AROUND 70/LOW 70S THROUGH
THURSDAY.
