-The Climate Prediction Center released it's updated December 2012 outlook Today.  Gone is the potential for below average temps in the Dakotas and Minnesota.  This new outlook is kind of similar to the LRC's December forecast.  I think were in for a roller coaster ride in terms of temperatures here in Minnesota.  The coldest air will proabably occur during the middle of the month and into Christmas week.

*Alert* Snow is in the forecast Thanksgiving Evening-Friday AM, a couple inches could fall; LRC forecast for December.

/Issued 3:35 PM CST, Tuesday, November 20th, 2012/

-Snow? Yes, snow is in the forecast later this week.  Several inches of it could accumulate Thursday Night, especially in Northern Minnesota and possibly in far Northern Wisconsin.  The HPC has outlined those areas in a Slight Risk for at least 4" of snow Thursday Night.  More details below...

 Lezak Recurring Cycle (LRC).  Ever hear of it? If not, I'll give you a brief description of what it is.  Every fall a unique weather pattern develops that repeats itself throughout the year.  The cycle length varies each year, sometimes it can be as short as 40 days, other times it can be over 50 days. 

This winter for the 1st time ever I will be posting what the LRC is forecasting for Duluth, I'm actually going to start doing this Today.

Big thanks goes out to Josh Herman, he's the one that got me into the LRC 2 years ago.  Josh is an LRC guru and a great guy!  If you're on Twitter, give Josh a follow @OSNW3.

*Looking ahead…

Mild temperatures thru Thanksgiving Day; Windy and colder Thursday Night-Friday with possible snow showers.

-Well, the 12z EUROPEAN model from November 19th is showing quite a storm for the middle of next week, this map is for next Wednesday, November 28th, 2012 and shows a tightly wrapped up low centered between Chicago, Illinois and Milwaukee, Wisconsin.  Should this storm materialize and track like that, then the heaviest corridor of snow would likely setup from Southern Minnesota into Central Wisconsin.  Word of caution, this potential storm is over a week away and the track of the storm, the timing, and strength will likely change, so stay tuned! This is more of a heads up then anything else, just keep the November 27-29 time period in the back of your mind for potential trouble from the weather.
