Tim from Springfield (IL) Posted January 14, 2017 Share Posted January 14, 2017 As we found out during the Dec. 16-17 "freezing drizzle" (followed by the deep freeze) that messed up central Illinois roads for several days afterwards (and my side streets near my apartment in Springfield never saw a salt truck until at least the following Monday, if at all), it doesn't take much of a glaze to mess up traffic. Hopefully it doesn't end up as bad as expected, especially as far as power and tree damage is concerned. Link to comment Share on other sites More sharing options...

Indystorm Posted January 14, 2017 Share Posted January 14, 2017 Not too bad here in Indpls metro. 33 with drizzle and some fog moving in from the south at present. Only very light icing IMBY early this a.m. that melted off. Hope we can get through this next round overnight without too many issues. Link to comment Share on other sites More sharing options...

cyclone77 Posted January 15, 2017 Share Posted January 15, 2017 All of the models have gotten significantly wetter for the DVN area compared to the last several days. Now deposits over an inch of precip, with some as high as 1.30" by early Tue. Only expecting a tenth or two of glaze before we melt over to rain later tomorrow morning though. Man, if temps would have stayed about 3 degrees colder through the event this would have been a terrible ice storm for this area. Link to comment Share on other sites More sharing options...

Yes, it could have been pretty bad, but like all recent systems this one will bring a nice warm surge. The ground is frozen, so an inch of rain should lead to some decent pooling in my yard. A one-inch swath of qpf through the region in mid January would normally have the forum buzzing, but not this winter. Link to comment Share on other sites More sharing options...
Hoosier Posted January 15, 2017 Author Share Posted January 15, 2017 LOT issued an advisory for about the western half of the cwa. Wonder if it might need to be expanded eastward though as the most recent model runs seem to be speeding up saturation slightly (after having slowed down).

ConvectiveIA Posted January 15, 2017 Share Posted January 15, 2017 DSM isn't budging just yet on status of Precip type, although they've not yet released their aftn package. However temperatures did climb a few degrees higher than originally anticipated here so in my estimation that brings into question ptype and ice accums. It's currently 33-34 degrees, though it's possible that's just urban heat island effect that would be mixed down by colder air tens of feet above the city once precip and nightttime start.

Hoosier Posted January 16, 2017 Author Share Posted January 16, 2017 Dewpoint is only 18 at ORD. Even assuming it comes up some in the next several hours, that leaves a good amount of room to play with in terms of evaporative cooling to try to keep temps AOB freezing. While it won't be a big storm for Chicago, I have a feeling that things may need to be beefed up some, especially outside the most urban core area.

Assuming saturation occurs in the areas not in the advisory, especially in the Chicago metro, then there's gonna be some frozen precip and IMO we should have an advisory out. Ice on roads is different than snow amounts to designate advisory counties. All it takes is a light glaze on roads to cause a significant travel hazard.

Helps a bit that it will be a lower volume commute tomorrow because of the holiday, but still striking at a bad time. Link to comment Share on other sites More sharing options...
ConvectiveIA Posted January 16, 2017 Share Posted January 16, 2017 First rain has just arrived here, but there's not yet any icing out of it. With an air temperature of 32 right now, it is going to be marginal for icing to take hold for the mean time. Not sure about more outlying areas however.

Indystorm Posted January 16, 2017 Share Posted January 16, 2017 Much ado about nothing with this whole ice episode here in Indpls area. When I think of model output from a week ago for this area....sheesh! Learn my lesson. Good luck to you farther north. Link to comment Share on other sites More sharing options...
TugHillMatt Posted January 16, 2017 Share Posted January 16, 2017 I don't envy anybody who gets freezing rain. One form of wintry precip. I have no desire to deal with. Too many memories from the 90s in PA of many ice storms with wind breaking trees, snapping power lines, injuring people, and aiding in many accidents.

Stebo Posted January 16, 2017 Share Posted January 16, 2017 Latest model runs are increasing the ice potential here in the Detroit area tomorrow evening, especially north of 8 mile. I would expect advisories to be issued tomorrow morning for tomorrow night. Link to comment Share on other sites More sharing options...
cyclone77 Posted January 16, 2017 Share Posted January 16, 2017 Still awaiting the first precip here. Should see some sporadic bursts of light freezing rain in a few hours, but won't really amount to much. Most guidance bumps us up to freezing by mid morning tomorrow, so we may not even see a tenth of glaze. Looks like some steady heavier rains all afternoon tomorrow though, and maybe a little thunder tomorrow evening. Easily the most significant precip event here since way back on Dec 4th. 1"+ of rain is looking pretty likely. Link to comment Share on other sites More sharing options...
cyclone77 Posted January 16, 2017 Share Posted January 16, 2017 Precip has been extremely light so far, amounting to maybe a few hundreths. Temp already at freezing, so even the light glazing event was pretty much a non-event. HRRR is overdoing precip in MO, so we may have a hard time getting the 1"+ precip the models have been advertising. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted January 16, 2017 Share Posted January 16, 2017 It is very icy here, but the ice layer is paper thin. The main surge of precip has arrived, but now the temp is above 32 so it won't be a big deal. Link to comment Share on other sites More sharing options...

Chambana Posted January 16, 2017 Share Posted January 16, 2017 The big story here has been the fog, visibility 1/4 mile or less since 7AM this morning. Been awhile since we had a day like this. The "freezing rain advisory" ended being a bust, hardly had any glazing, very minimal Saturday morning, when it turned to all liquid 3 hours later. The 12/18/16 event with freezing mist and drizzle caused more disruption than this. Link to comment Share on other sites More sharing options...
