Extended Outlook: ColdNovember 19th, 2013 at 5:54 pm by Bill Steffen under Bill's Blog, Weather
These are the 6-10 day temperatures outlook on the left and the 8-14 day temperature outlook on the right. Blue areas indicate a higher than average chance of colder than average temperatures. The orange colors indicate areas where temperatures have a greater than average chance of being warmer than average. As you can see, a large part of the country is going to be feelin’ the chill over the next week. The GFS gives Grand Rapids a high of 28 on Saturday and 23 Sunday afternoon! The European model has low 30s Saturday afternoon and mid-upper 20s on Sunday. It looks like even inland areas could get an inch (or two) with the best lake-effect band at +6″. The mid-Lake Michigan buoy shows a water temperature of 46. The European model predicts the temperature a mile above ground will dip to zero Sunday AM, so that’ll be a 45 degree difference.
