Turning Toward Fall

Bill's Blog

The map above shows the 8-14 day temperature outlook from the Climate Prediction Center for Sept. 26 – Oct. 2.  Much of the Central U.S. into the Great Lakes has turned blue.  That mean a likelihood of cooler than average temperatures.  So far, this month has been 5.1 deg. warmer than average.  A sharp cold front moves thru Friday AM and temps. will start to fall Friday PM.  Saturday will see highs in the mid-upper 60s.  The real cool air arrives in about a week. Average high temperatures at the start of October are in the mid 60s, so if we’re cooler than that…it’ll be a significant change.

The map above is the forecast temperature difference from average for Thurs. 9/27.  Temperatures in MI are about 5 deg. cooler than average.  It’s warm along the coasts.  What’s interesting is the large amount of Canada that is considerably colder than average (map from weathermodels.com).  It’s going to be quite a change

This is North American snow and ice cover.  You can see there is snow on the ground in far northern Canada (Nunavut).  Winter comes early there.  Barrow AK had a high temp. of 33F on Tue.
