.DISCUSSION...
CONVECTIVE POTENTIAL REMAINS OVER EASTERN AREAS INTO THIS EVENING
ANYWAY. INCREDIBLE INSTABILITY REMAINS ALONG PREVIOUS EAST CENTRAL
MN SUPERCELL OUTFLOW. RADAR SHOWING BOUNDARY ROUGHLY FROM
LITCHFIELD TO JORDAN AND NORTHFIELD. THIS APPEARS TO BE LIFTING
NORTH. SPC MESOSCALE ANALYSIS SHOWING MLCAPE IN EXCESS OF 6500
J/KG IN A NARROW CORRIDOR OVER THE SOUTHERN METRO INTO SOUTHEAST
MN WITH SOME SURFACE VORTICITY AND HEALTHY 0-3KM MLCAPE
ASSOCIATED. AREA STILL UNDER THE GUN FOR DEVELOPMENT AND WILL
CONTINUE TO MONITOR. THIS WILL SHIFT NORTH AND EAST DURING THE
EVENING AND SHOULD END MUCH OF THE THREAT OVERNIGHT. WILL MAINTAIN
SLIGHT CHANCE OF THUNDER NORTHERN PERIPHERY AFTER MIDNIGHT IN
CASE ACTIVITY DEVELOPS OVER THE DAKOTAS AND MOVES INTO NORTHWEST
CWA LATE TONIGHT.
HEAT REMAINS AN ISSUE AND WILL CONTINUE HEAT WARNING FOR THE
AREA. SURFACE FRONT IS PROGGED TO MOVE ACROSS THE AREA WEDNESDAY
NIGHT AND WILL BREAK THE HEAT WAVE FOR THE AREA. CAPPED ATMOSPHERE
REMAINS IN PLACE AHEAD OF FRONT. MODELS SUGGEST DECENT MOISTURE
TRANSPORT LIFTING AHEAD OF THE FRONT AND MAY BE STRONG ENOUGH TO
ERODE LOW LEVEL CAP. THIS MAY INTIATE AT LEAST SOME ISOLD
CONVECTION ALONG THE BOUNDARY LATER IN THE AFTERNOON...AND THE
INCREDIBLE INSTABILITY WILL CONTINUE THE SEVERE WEATHER THREAT
INTO WEDNESDAY EVENING. THIS EXITS MOST OF THE AREA THROUGH 06Z
THU AND EXPECT SOME COOLER/DRIER CONDITIONS THURSDAY.
RETURN FLOW AND INSTABILITY LIFTS NORTH INTO THE REGION LATER THURSDAY
NIGHT AND FRIDAY. WILL MENTION SOME SMALL POPS FOR THIS THREAT AS
IT MOVES NORTH. LONGER TERM SHOWING TREND OF NEXT WAVE/SURFACE
FRONT MOVING THROUGH THE AREA SATURDAY NIGHT. GFS CONTINUES ITS
TREND OF LARGE SURFACE HIGH MOVING ACROSS THE AREA THE REST OF THE
WEEKEND INTO EARLY NEXT WEEK. MEAN GFS ENSEMBLES CONTINUE DRY
TREND THROUGH TUESDAY. WILL HOLD OFF ON LOW POPS FOR TUESDAY.

.AVIATION.../18Z TAF ISSUANCE/
ISOLATED SVR THUNDERSTORM CELL HAS WEAKENED IN THE LAST HALF HOUR
OR SO...THUS THUNDER MOVING OUT OF THE MSP AREA. A LITTLE
PROBLEMATIC FOR THE REST OF FOE-RECAST AREA THIS AFTERNOON AND
EVENING. THERE IS A FRONTAL BOUNDARY STILL OVER THE CENTRAL
MINNESOTA AREA WHICH COULD BE FOCUS FOR ADDITIONAL DEVELOPMENT LATE
THIS AFTERNOON OR EVENING. HOWEVER...WARMER MID LEVEL TEMPERATURES
MOVING INTO THE AREA COULD PREVENT ANY DEVELOPMENT THE GREATEST
RISK WOULD BE IN THE VCNTY OF KSTC AND POSSIBLY KRNH OR KEAU. WILL
INCLUDE A CB FOR NOW IN THOSE LOCATIONS. OTHERWISE EXPECT VFR
CONDITIONS THROUGH THE PERIOD..EXPECT FOR THE POSSIBILITY OF SOME
MVFR VSBYS IN FOG CENTRAL MN LATE TONIGHT. EXPECT GUSTY SOUTH TO
SOUTHWEST WINDS TO DEVELOP WEDNESDAY MORNING WITH GUSTS TO 25
KNOTS OUT OF THE SOUTH..SOUTHWEST.
KMSP...THUNDER THREAT ENDED FOR KMSP WITH VFR CONDITIONS EXPECTED
THROUGH THE PERIOD. THERE IS AN OUTSIDE CHANCE OF SOME DEVELOPMENT
WITH THE FRONTAL BOUNDARY JUST TO OUR NORTH...BUT AS MENTIONED
ABOVE...THE WARMER MID LEVEL TEMPS WILL LIKELY PREVENT THAT
HERE. SOUTHEAST WIND WITH A FEW GUSTS TURNING MORE SOUTH AFTER
20Z. GUSTY SOUTH TO SOUTHWEST WINDS TO 25 KNOTS DEVELOPING ON

A large swath of damage occurred from the northwestern edge of Pipe Lake on 220th Avenue, south and east along Pipe Lake, then southeast to the southeast side of Long Lake. The winds caused damage to boat lifts, boat docks, and buildings near Pipe Lake and around Johnstown Township. At least 100 large trees were downed, with some falling on homes, vehicles, and outbuildings. This wind damage was associated with the rear flank downdraft portion of a tornadic thunderstorm.
A weak tornado knocked down several dozen trees before crossing Pipe Lake, and dissipated on the eastern shore of Pipe Lake. A damage survey revealed the tornadic winds were about 65 mph. Just to the west of the tornado was a strong rear flank downdraft, with winds just less than 80 mph, which knocked down at least 100 trees (see separate entry).
