Severe Recap, Wildfire Update, and possible Cyclone Formation in Northwest Atlantic

Monday, June 18th, 2012

After a stormy night, lingering showers and thunderstorms across the Twin Cities produced this neat sight… Mammatus clouds, which indicate unsettled weather and possibly thunderstorms nearby.

Storm Reports From Sunday

These are the hail, high wind and tornado reports from Sunday… note the red dots near the South Dakota/Minnesota boarder… those are tornado reports! As thunderstorms merged into a line, they produced more wind damage into central Minnesota and near the Twin Cities.

Storm Damage in Ortonville, MN

Thanks to the National Weather Service out of Aberdeen, SD for sharing this picture from The Ortonville Independent

“Ortonville hit by storm. Main St (2nd) is a mess.

Rotating Wall Cloud

This picture is from Andy Mair, who was watching a rotating thunderstorm that produced a funnel cloud near Benson, MN

Heavy Rain

These thunderstorms produced some heavy rain! Radar estimates of rain from Sunday night’s early Monday morning’s event show nearly 2″ to 4″ swath from western Minnesota into west central Wisconsin.

Thanks to WeatherNation meteorologist Bryan Karrick for the picture below of his rain gauge… Bryan picked up nearly 3.5″ of rain and said his sump pump is getting a good workout.

Severe Threat Today

The Storm Prediction Center has highlighted areas across the Upper Mississippi Valley and the Great Lakes Region for a chance at strong to severe storms later today. Hail and high winds look to be the primary threat along with more heavy rain, but an isolated tornado can’t be ruled out near northeastern Wisconsin.

Severe Threat Tomorrow

The last full day of Spring 2012 will be comprised of another thundery outbreak across the far north. Hail and high winds looks to be the main threat along with more heavy rain.

HPC Rainfall Forecast

Look at the heavier rain forecast across the far north… the potential for another 2″ to 4″ or more is possible through the end of the week.

Extreme Heat

Most of this rain and thunder activity is/will be developing on the out edge of the extreme heat and humidity that is bubbling up through the central part of the country. Look at the 500mb vorticity map from across the nation by the early part of next week allowing more heat to settle into the central part of the country.

Winds Fuel Colorado Wildfire 

Wildfires continue out west. Hot, dry and windy conditions aren’t helping the situation.

Chance of Tropical Cyclone Formation in the Northwest Atlantic

A well-defined non-tropical area of low pressure located about 300 miles northeast of Bermuda is producing gale-force winds and scattered showers and thunderstorms. This system could gradually acquire subtropical cyclone characteristics as it moves northeastward at around 10 mph over the next couple of days. This system has a medium chance, 30%, of becoming a subtropical or tropical cyclone during the next 48 hours. This image was taken by GOES East at 1415Z on June 18, 2012.

Storm Names

If this thing develops into a tropical storm, then it’s name will be Chris… the third name on the Atlantic name list for 2012. Interested in seeing if your name is on the list of potential upcoming tropical storms or hurricanes in the future? See the list below from the NHC and find out more about the naming convention HERE:

Alrighty, thanks for checking in on this Monday, have a great rest of your week!

National Weather Headlines For Monday, June 18th, 2012

 Sunday’s Severe Storms
Strong to severe thunderstorms developed across eastern South Dakota and western Minnesota Sunday evening. A tornado was reported by spotters near Wheaton, MN. The picture below is courtesy Meteorologist Jerrid Sebesta from KARE 11, who got the picture from a viewer. That storm looks pretty wrapped up! Almost looks like a tornado could drop at any time!
Weekend Northern Lights

Thanks to Bob King for the picture below who captured Saturday night’s/early Sunday morning’s northern lights.
Grandma’s Marathon Weekend
It was Grandma’s Marathon weekend in Duluth, MN… probably one of my favorite annual events! Now with 2 little boys at home, I find it harder and harder to get up there to run in the event… hopefully someday again very soon!
Thanks to Paul M. Walsh for the very inspiring picture below (See more of his pictures HERE)

 Somewhat Soggy Saturday
Thanks to my good friend, Roxanne Perala Wilmes from Duluth, for the picture below! It was a dry and sunny start to the day, but scattered showers and storms developed in the early afternoon hours and blew through during the early evening. It looks like the streets of downtown Duluth are a little soggy in this picture, likely as some of the last few full marathon runners were heading into the last mile of the race.

Waters Receding in Cannon Falls
After Thursday’s 8″+ of rain and flash flooding in Cannon Falls, receding wasters have revealed some interesting things.
Thanks to my good friend Brad Nelson for the picture below of a tree that was consumed by the high water. Here is Brad’s commentary: 
“Debris hung up underneath a walking bridge after the water had receded from the flooding in Cannon Falls on Thursday. Whole trees ripped out and caught in there!”

Camera Apps
One of my new favorite camera apps for a smart phone is called 360 Panorama… It’s a nice way to take a 360 degree picture of something!
Thanks to Joey Deese for the picture below.

5 Day Rainfall Forecast
Rounds of thunderstorms will move through the Upper Mississippi Valley with the potential of heavy rain. The HPC 5 day rainfall forecast suggests over 3″ of rain possible (with isolated higher totals possible). The graphic below was the 5 day forecast from 7pm Sunday-7pm Thursday.

  Monday Severe Risk
After a stormy start across parts of Minnesota on Monday, the severe thunderstorm risk will shift east into Wisconsin through the afternoon/evening hours.
U.S. Heat Wave Expected Later This Week
…Heat Wave Forecast for Later This Week…

“Below average high temperatures over the Mid-Atlantic region will be a thing of the past by mid-week. Temperatures are expected to climb into the 90s by Wednesday. Combined with high humidity, the air temperature could feel as hot as 110 degrees in some areas in Virginia on Wednesday. The Washington D.C. area could feel like a sweltering 105 degrees. The hottest temps will shift into the southeast in the long term.”

Thanks for checking in, have a great week ahead and enjoy the last few days of Spring 2012! Summer arrives at 6:09pm on Wednesday.
