Those storms dropped very heavy amounts of rain in a short period of time to the West-North parts of Duluth, 2 to nearly 4" of rain fell which led to some flooding late Sunday Evening. Thanks for viewing.

Sunday, May 23rd, 2010 Storm Chase Trip #2

Sunday, May 23rd, 2010 was a Slight Risk for severe thunderstorm day across parts of Eastcentral Minnesota, the risk area was so close to Duluth that Shawn, Sam, and myself couldn't resist going out for a short chase down I35 with Moose Lake, Minnesota our target area. The overall set-up was questionable due to less than stellar amounts of shear, winds aloft were also quite weak which in most cases results in only isolated severe weather at best. But, the positives included very high amounts of instability (CAPE), as well as a ton of moisture, and a cold front albeit a weak one which had just enough convergence along it to bust through a strong layer of warm air aloft (CAP). Scattered thunderstorms did develop to the west-north of Moose Lake MN Sunday late Afternoon-Evening with a few of these storms turning severe at times north of Duluth and east of Hibbing MN, those storms couldn't really move toward the east, instead they were lifting northeast and riding along the edge o…
