June 24th, 2010 Storm Chase Trip

Image
This was our shortest storm chase trip of 2010 (thus far) for Shawn and I as we only had to go northwest out of Duluth by 15 miles or so. A very intense supercell thunderstorm blew up between 2-3 PM CDT Thursday, June 24th, 2010 about 10-15 miles north-northeast of Grand Rapids, Minnesota...Eastcentral Itasca County. This storm tracked southeast and became tornado warned with reports of funnel clouds and wall clouds as it reached Southwest Saint Louis County MN. The severe storm continued on it's southeast track, passing through Saginaw, Adolph, Hermantown, Proctor, Duluth, and Superior between 5:40 PM-6:30 PM CDT Thursday. This storm had an amazing amount of cloud to ground lightning strikes (CG'S) one of the better lightning displays I've seen around Duluth in quite some-time. This storm produced scattered amounts of wind damage in and near the Twin Ports, it also produced quite a bit of hail, generally up to 1.00" in diameter. Rainfall was also extremely heavy…

June 22nd 2010 Storm Chase Trip

Image
Shawn and I decided to take a trip down to the Moose Lake/Sturgeon Lake Minnesota area's late Tuesday Afternoon June 22nd, 2010 to chase on a Slight Risk day. The atmosphere was plenty unstable on Tuesday with enough warmth and a nice surge of moisture, winds aloft were also on the strong side...The negatives were that temperatures aloft were just warm enough to keep a lid on convection in Northern Pine/Southern Carlton Counties MN (where we were at) until around 8 PM. We sat in the Moose Lake/Sturgeon Lake areas for close to 2 hours watching towers go up, spread out, and dissipate...Meanwhile, the storm of the day was tracking E-SE across portions of Northwest Wisconsin, this storm was supercelluar with quite a few reports of wind and hail damage, this storm even turned into a tornado warning for a time around 8 PM Tuesday Evening. I had a nice view of the severe storm in Northwest Wisconsin (east of our location), and in the other pictures you can see how the anvils would spr…

6/22/10: SEVERE POTENTIAL

Issued at 12:19 PM CDT, Tuesday, June 22nd, 2010

...SCATTERED SEVERE THUNDERSTORMS POSSIBLE LATE THIS AFTERNOON AND THIS EVENING...

Timing:
*4:00 PM until 11:00 PM CDT.

Main hazards:
*Damaging winds an excess of 60 mph
*Large hail at or greater than 1.00" in diameter
*Locally heavy rain and dangerous lightning

Discussion:

A cold front will settle south/east out of Northwest Minnesota This Afternoon and Tonight. A warm, moist, and unstable airmass was in place out ahead of this front and this should lead to the development of scattered showers and thunderstorms This Afternoon and Tonight across our area... A few of these storms could turn severe especially late This Afternoon and Evening thanks to strong winds in the mid and upper levels of the atmosphere along with some decent wind shear.

Although the majority of our area is under a Slight Risk for Severe Thunderstorms This Afternoon and Evening, it appears that the best chance for possible severe weather would be along and west of a li…
