Amazing image of the developing (severe) storms mushrooming just to our east. RUN to the window to check these out, they appear to be vast, sprawling, thermonuclear towers of rapidly rising air. Once these violent columns of rising air reach the stratosphere (where temperatures get warmer with altitude) the air spreads out into the classic "anvil" shape, the T-storm's flat "cap". Low 90s in southeastern Minnesota, while recent reports show rain mixing with a little wet snow up in Park Rapids last hour. What a crazy state we live in!
Doppler Radar image showing large, hail-producing "supercell" thunderstorms tracking toward Winona, Lake City and La Crosse area. Reports of 1.5 to 2" diameter hail east of Rochester. The red outlines of "polygons" are provided by the NWS; these are the "high-threat" areas within specific counties where the risk of hail/damaging winds is greatest. Remember that a severe storm watch is posted for southeastern MN and much of Wisconsin until 11 pm. Tornadoes can form in situations like this, even though a tornado watch isn't posted. This squall line will probably continue to intensify up until 8 or 9 pm - but again, the risk is now well south/east of MSP.
