Unbelievable COLD!!January 17th, 2014 at 1:02 am by Bill Steffen under Bill's Blog, Weather
Click on the graphic to enlarge. This is the 240-hour GFS model valid Sunday evening the 26th. At this point, I’ll guess this is overdone. For the sake of a lot of people who would be burdened by this kind of Arctic attack, I hope it’s overdone. I don’t think I’ve seen a map this cold for the Great Lakes since 1994. The map shows a 1000-500 mb thickness of about 483. The GFS-plot gives G.R. a temperature of -9 at 7 pm on the 26th with a west wind at 25 mph! That would give a wind chill of -36. The model keeps the temperature below zero in G.R. from midday Sunday to Weds. morning! It takes Milwaukee as cold as -25 and if MKE is -25 with a strong west wind, it could really be -10 to -14 on this side of Lake Michigan, even with a west wind coming off Lake Michigan. Just look at the temperatures on the GFS-plot for Milwaukee! It looks like a plot from Siberia! It’s not just the extreme cold, it’s the length of time…10 days, 2 weeks of bone-chilling cold. Look at how much energy we will using heating during this period. Think about how tough this would be on wildlife. OK – the European isn’t quite as cold. It does take the temp. in G.R. a little below zero next Tue., Wed., and Thur. mornings with daytime temps. around 10-15. We have one day that is not quite as cold, mid-upper 20s on Friday the 24th and the Euro. has highs around 15 on Saturday the 25th and maybe 17 on Sunday the 26th with lows around 0 to +5…definitely not warm, but no where near as brutal as the GFS. More later…it’s after 3 am and I’ve got a haircut scheduled at 1 PM…gotta get a little sleep.
2:50 pm: Morning run of the GFS looks real cold for the next week east of the Rockies. Coldest relative to average centered over MN and WI. Frost this AM in Naples FL. Gigantic pyrocumulus cloud rises over wildfire in Victoria, Australia. Temperatures -30 to -45 and winds gusting to 45-65 mph in Northwest Alaska.
