Central Great Lakes sector loop Radars here should update automatically.  Showers and t-storms with brief heavy rain moving thru W. Michigan. Here’s a link to national lightning data.   Evening run of the NAM model takes the temp. in G.R. down to 45 at 7 am, 32 at 7 pm tomorrow and mid 20s Weds.  AM.  It stays windy thru early Weds. and that will lower wind chills down to 10-15 above by Weds. AM.  Video of cloud-to-ground lightning bolt in W. Michigan in Dec. The cold air pushes into the South with one model predicting a snowstorm here in Central Alabama where I’m spending the night.  AWESOME weather video at the link.

  The entire state of Michigan is in the General Thunderstorm Outlook for tonight (light green area on the map), with a Marginal Severe Risk for parts of Missouri, NW Arkansas and E. Oklahoma.

There have been at least 15 severe reports from Missouri down into NW Arkansas and E. Oklahoma.

The daily record high temp. for today is 65 in G.R.  we shouldn’t get that warm.  A Wind Advisory is in effect for the lakeshore counties and  Gale Warnings are in effect for Lake Michigan until Wednesday AM.  Gusts to 40 mph are possible, esp. at Lake Michigan.  Waves could reach 13 feet on Lake Michigan and 20 feet on Lake Superior.

The cold front comes through tonight with temps. falling to near 40 tomorrow AM, down to the low – mid 30s by late tomorrow PM, then into the 20s tomorrow night, when snowflakes will be flying and roads will get slick. Temps. should reach the low 20s by Weds. AM and hold in the 20s. to near 30 for highs the rest of the week (plenty cold enough for lots of light and occasionally heavy – esp. in the lakeshore counties).  We’ll see snow much of the rest of the week beyond Tuesday.  Everyone will see snow accumulations along with periods of slick driving.  Areas (mainly lakeshore counties) that get the heaviest snow should see 6-12+” of snowfall (though with the relatively warm ground we may not get a foot of snow accumulating on the ground.  Cold pattern for Michigan, the Great Lakes and the Eastern U.S.

The heaviest snow in the state will likely fall close to Lake Superior where 1-2 feet could accumulate from Ironwood northeast into the Keewenaw Peninsula.

Here’s a Monday evening surface weather map, with the cold front heading thru Wisconsin toward Michigan.and a deep low pressure center near Lake Superior, pumping the warm air up ahead of the cold front and bringing the cold air with stiff northwest winds.

Also:  Fallstreak hole in OklahomaTime lapse of the fallstreak holeWildfire north of Los Angeles – college evacuated.  Six nighttime helicopters fighting that fire.  Smoke seen easily on Doppler Radar.  Wawona Road (continuation of Hwy 41 in Yosemite N.P. ) is closed from Chinquapin to Yosemite Valley due to high winds/fallen trees.
