100% Chance of RainJanuary 10th, 2014 at 2:36 am by Bill Steffen under Bill's Blog, Weather
SAT. AM - Despite temperatures in the low 40s, we still have reports of icy roads and slide-offs. There’s also ponding of water on roads. Over an inch of rain has fallen in Grand Haven and 3/4″ here in G.R. Kalamazoo and Battle Creek were just shy of 1/2″. There is also a concern that the additional runoff into area rivers will cause the ice to break up, leading to possible ice jams. We’ll all see icy spots as temps. fall below freezing Sat. night. I’m on the cold side of the model data for the middle-end of next week. With the thaw, watch out for falling icicles. Observe odd/even parking where applicable. Clear fire hydrants, drains and downspouts. Here’s the GRR NWS forecast discussion, current Michigan temperatures, and a national weather map. Here’s the NAM model 84-hour snowfall and GFS model snowfall thru 120-hours . ICE expanding rapidly on the Great Lakes. Model update from last night’s data: The overnight European prints out 0.76″ of mostly rain (maybe 1/2-1″ of snow as it tapers off Sat. pm. Most of the rain will fall from 4 pm Fri. to 9 am Sat. Temperatures will rise to 38-40 Fri. night shortly after midnight, then fall to 32 by late Saturday and at least down into the upper 20s by Sunday morning. That means all the slush and all the puddles will ice up by the Sunday church commute. Sunday may be the best chance of a dry day, though it’ll be breezy and cool. Monday on the Euro. is mainly dry with highs in the upper 30s to near 4o. The Euro. has 1/2″ of snow Tue. and low 30s…Wednesday is a cold day with snow showers and temps. in the low-mid 20s. Thursday we’re back to a chance of a light snow and low 30s…then chilly next Friday. The GFS has 0.79″ of rain (very similar to the Euro.) …an overnight max of 38 or 39…falling to the mid-upper 20s with a freeze up Sat. night. It has .05″ of a mix Monday, what could be 2-4″ of snow Tues. with temps. slowly falling during the day from 30 to 25. Weds. is chilly, low-mid 20s, Thurs. back to 34…Friday is chilly again, low-mid 20s. For what it’s worth, the GFS prints out 40 for the 21st and 23rd…way too early to put any stock in that. The NAM is the wettest at 1.09″ with the rain starting at 32.4 deg…it has a max. of 36 Fri. Night (I’ll buy the warmer Euro.) Sunday am is down to 25, 36 breezy and dry Sun. PM, a little rain or a mix Monday night (the NAM only goes out 72 hrs.). Links: Grand Rapids radar, Northern Indiana radar, Chicago radar, Detroit radar and Milwaukee radar.
