This is a pic. from Al Kebless. Click the picture to enlarge. This picture was taken on October 24, Thursday at 5:15 pm looking N-NW on Meyers Lake Road and 13 Mile Road in Rockford It looks like a rain foot, though it would have to be from a relatively small shower. Speaking of rain. It’s going to rain late Tues. night and Weds…pretty much a 100% chance. It’ll be the wettest day of the week. Grand Rapids gets 0.57″ of rain from the NAM (caribou), 0.85″ from the European model and 0.92″ from the GFS. We get to the upper 50s (60 if lucky) today, 50s Weds. then back to the 40s. It may be cold enough early Thurs. for a light rain/snow shower, but if you do see a little snow, it’ll melt on contact with the ground. Pretty cold air out west. As I write this it’s already -1F at Yellowstone Natl. Park and -10F not too far north of Calgary, Alberta. Check out the Kelvin-Helmholtz wave clouds. October global temperature.
The morning run of the NAM (caribou is in). It keeps us dry thru this evening…chc. showers after about 1 am…definite rain most of tomorrow (Weds.) with 0.70″ for G.R…near 60 today, mid 40s during the afternoon Thurs. and Fri. Could be a light lake-effect rain or mix shower Thurs., Thurs. night…nothing that would stick even if you saw some snowflakes. The GFS model run from this morning’s data gives G.R. 0.79″ of rain starting also around 2 am thru about 2 pm Weds. (for G.R. – rain ends later SE of G.R.) with a sprinkle or two after 2 pm. The European gives G.R. 0.71″ of rain, so the models are all in the same ball park. It gives us cold enough air at 850 mb for a few flakes Thurs./Thurs. night, but the overall airmass is pretty dry by then. 3-6″ snow possible for Minneapolis. Chilly this AM in New England and out west. It was -1 in Salmon ID and -2 at Yellowstone N.P. I see a -8F north of Calgary, Alberta.
