Thunderstorm SNAIL Core? “Cut-Off” Low Cools Spring Fever Thru Early May

Monday April 29th, 2013

Earlier Monday we were tracking a severe thunderstorm rolling across central Iowa. There were several hail reports across Hwy I-20 up to 1.25″ in diameter. As I inspected the storm, I thought it looked more like a SNAIL core to me, what do you think?

Shovelable Hail?

The National Weather Service received a report from an Iowa State Trooper near Steamboat Rock of accumulating hail that was 2″ deep!

Severe Threat Monday

The thunderstorm mentioned above developed along a slow moving/stalled frontal boundary that will be capable of producing a few more strong thunderstorms today and tomorrow. The main threat with these storms will be hail and high winds.

Severe Threat Tuesday

Some of the same areas that could see thunderstorm on Monday, could see additional thunderstorms on Tuesday as well!

Cut-Off Low

Take a look at the whacky weather map below. It shows a feature known as a “Cut-Off” low pressure system, which can typically produce cool, cloudy and soggy weather for days. This will also help to limit the number of severe weather days in early May!

6 to 10 Day Temp Outlook

NOAA’s Climate Prediction Center shows a good chance of below normal temperatures for a large part of the country through the 8th of May. UGH! Not only will this cool us down considerably, but this will also have a big impact on limiting severe weather chances through the early part of May!

Say It Ain’t Snow…

This is unreal… The GFS (American Model) is suggesting snow potential for some across the Upper Mississippi Valley by mid/late week. Can you believe it? Let’s hope this fizzles!

Thanks for checking in, have a great rest of your week ahead!
