*Isaac won't be bothering the Northland this weekend, but it will hit the Ohio Valley, and points west-south with lots of rain, some locations could receive more than 3-5" of rain this Labor Day weekend, this will put a dent in the ongoing drought, but in the short term it may lead to some flash flooding.

Interesting!  On August 15th, 2012 much of Minnesota was in a Slight Risk for Severe Thunderstorms, and a Severe Thunderstorm Watch was issued later in the day, yet only 10 severe weather reports occurred per Storm Prediction Center.  On August 23, 2012 portions of Minnesota were under a "See Text" which means only a marginal threat for any severe weather, no watches were issued, yet there was a total of 29 severe weather reports in Minnesota.  We had more severe events on a non-slight risk/no watch day, versus a day where we had a watch and were under a slight severe weather risk.  Go figure.

Weather Tidbits:
-Today is the 5th time this month and the 40th time in 2012 with a high temperature of at least 80 degrees at Duluth, Minnesota (Airport location)

A big thunderstorm hugging Lake Superior's North Shore This Afternoon. Doppler radar shots from this storm, including Dual Pol.

Issued at 4:20 PM CDT, Thursday August 23rd, 2012

A long lived thunderstorm, severe at times has been rolling NE along the North Shore of Lake Superior in Northeastern Minnesota since 2 PM.  This storm has turned severe once again with a threat for hail up to the size of golf balls in Southwest Cook and East Central Lake County until 5 PM CDT per NWS.

Here's a few radar grabs of this severe thunderstorm from GR3.

With the upgrade to Dual Pol radar, one can detect where hail may be falling (red areas on this map)

-Here's another way one can detect where hail may be falling.  This is the VIL radar.  The deeper cores of reds and whites is a pretty good indication there's at least some hail dropping from the sky.


Still a risk for a few showers/t'storms Tonight; warmer on Friday (80s) mainly dry; rain chance returns Saturday Afternoon-Night; dry for Sunday.
