Classic Mid Latitude Cyclone

What a storm! Not too often can we see storm like this roll through the central part of the country. Although, every spring and fall, storm like this become a little more frequent. The reason is because the temperature from north to south becomes greater and the atmosphere is trying to balance itself out. As the atmosphere draws cold, dry air south and warm, moisture air north; a steady stream of moisture can cool and condense into rain/snow. Note radar echoes from the Gulf of Mexico to just south of the Twin Cities. Most of the images caught on radar are in the form of rain, but temperatures have been cold enough f0r snow across central Nebraska.


Here are a few of the hefty snowfall reports:

A little light snow/sleet may be possible at times today across central and southern Minnesota, but accumulations, if any, will be very light and slushy. The best chance for snow to accumulate on grassy surfaces will be in southwestern Minnesota and perhaps a couple of spots in southeastern Minnesota. Here then is the precipitation type forecast for Friday:


Precipitation totals will be greatest across southeastern Minnesota where more than 1" could be possible:


Todd's Outlook for the Twin Cities

Today: Breezy and cold for October - persistent clouds, rain showers and possibly some wet flakes. High: 42

Tonight: Light rain/snow mix early, then becoming partly cloudy late. Low: 32

Saturday: Partly cloudy, better day of the weekend. High: Near 50

Sunday: Getting cloudier, PM showers of rain mixed with wet snow. High: 45

Monday: Autumn-like with a slight chance of showers. High: 50

Tuesday: Slight chance of a spotty shower. High: 50

Wednesday: Sprinkles possible again. High: Mid 40's

Halloween Outlook: Mostly cloudy and chilly with a few sprinkles or flurries. High: 39 (Trick or Treat temperatures may be near freezing). Plan on a few extra layers under your kid's costumes - I have a feeling you're going to need them this year.
