Frosty Start and Lake Effect Snow

HamWeather Blog…

Frosty Start across the Midwest

Good Sunday Morning to you all! It was a frost start over a good chunk of the upper Midwest, ranging from northern Minnesota all the way into Missouri, with temperatures dipping into the upper teens in some places! The coolest temperature I have seen so far this morning was from Embarrass, MN, where it got down to 20 as of last report an hour before sunrise. Mainly over portions of northern Minnesota and into Wisconsin the growing season is likely over due to this frost and freeze that occurred this morning — but that also means that some of those pesky box elder bugs and wasps should be fading away. Hard to believe it will be winter soon over a portion of the nation! We are expecting a frost tonight to extend deep into the south, where Frost Advisories are already in effect as of this morning for portions of Arkansas and Tennessee for later tonight. Places that far south should be covering up their plants or bringing them inside to prevent them from dying if you want them to survive!

First Lake Effect of the Season

Speaking of winter, believe it or not we saw the first lake effect snow flurries of the season Saturday on the Upper Peninsula of Michigan at Gwinn Sawyer Airport. Nothing accumulated that we can find here at WeatherNation, but still another sign of winter… You can read more about this at the CIMSS Satellite Blog.

Atlantic Staying Calm

Hard to believe, but the Atlantic is staying calm at the moment. Two areas of disturbed weather, but neither look too impressive at the moment for development. Even if we do see some slow development out of the systems, neither show an immediate threat to the United States, as the global models show both curving back out to sea before reaching the US.

Doppler On Wheels

The Doppler on Wheels is a mobile Doppler system developed by Dr. Joshua Wurman that allows scientists to get up close and personal with severe weather events and rapidly scan these storms for research. During the year these vehicles are used for many different purposes — during the spring for severe storm events in the southern US, summer for hurricane landfalls (along with repairs) and during the college school year for student research. One of these vehicles has been deployed to St. Cloud State University on the first of several events for these vehicles this college school year where they will be studying Autumn Storms over the next 2-3 weeks. Unfortunately for the next week there is nothing promising in the forecast for a lot of the upper Midwest! Later this year the vehicles will be making trips to Washington DC, Vermont, Michigan and North Dakota before taking a trip across the Atlantic to England and France early next spring.

That’s it for this Sunday — hope you enjoy it!
