Wind Chill AdvisoryMarch 3rd, 2014 at 1:20 am by Bill Steffen under Bill's Blog, Weather
There’s a Wind Chill Advisory in effect until 10 am. Remember that wind chill is a function of wind and temperature and in this case, it’s almost all because of temperature as winds will be calm to rather light. Here’s current conditions (temperature and wind chill). At 1 am, Grand Rapids was +1°, Fremont -5°, Big Rapids -11° and Pellston has already been as low as -26° overnight. The record low temps. for 3/3 are -9 GRR, -10 MKG and -19 LAN. The evening run of the NAM (caribou) only gives GRR a high of 10 today (I think that’s too low) and it gives GRR 0.8″ of snow Tuesday, 0.5″ snow Tuesday night, and 0.6″ snow on Weds. It gives GRR a high of 27.2° on Weds. The GFS plot has high temperatures beginning today of 13, 24, 28, 31, 33. I’ll side with the warmer numbers plus a degree or two. The pattern looks cool thru at least the middle of the month (though not as cold as it is now). The GFS plot would give G.R. almost an inch of snow Tues., a little over an inch Tues. night, an inch from Weds. into Weds. night and then either a couple inches of snow or a mix (a period of freezing rain not impossible) on Friday.
