The book has been closed on January. Coldest January (5.2 degrees below normal) since 2014. Snowiest January since 2011. At least a trace of snow on 23 days, measurable snow on 13 days. There were 20 days that didn’t get above freezing. Finished the month with 15 consecutive days of snow cover. About as good as it can get if you ask me.
That’s significantly less bullish than they were on the ice potential earlier. The previous package had over a quarter inch for much of the metro.
They’ve also updated the zones to include a lot more mix during the day Thursday (with sleet more prevalent than zr).
That’s the bottom line. The goalposts are narrowing. The most plausible options are a sleet bomb or an ice storm or some combination of the two, with little rain or snow.
Everything so far is starting to suggest that we might be below freezing most of the day Thursday, but temps aloft don’t support snow during that timeframe. This can’t be good, unless you really want the crippling ice storm. Anyone?
NAM also has us below freezing all day Thursday from daybreak. More sleet than zr in Pittsburgh but the 1”+ ice totals are in southern Allegheny county.
More concerning is the fact that “crippling ice storm” is still on the table. 6z NAM is ugly in this regard. Nearly an inch of steady freezing rain starting Thursday morning and going through midnight. Saving grace might be that much of the event is during the day and temps are in the 31-32 range.
The heavy freezing rain and 31 degrees thing that @RitualOfTheTroutmentioned last night. Can’t imagine it’d be a massive ice storm, which is probably good.
Would presume by morning we’ll have a first look at a NWS forecast that takes into account the main period of the event (Thursday night).
ILN issued watches for their counties basically along and north of I-70 through western and central Ohio.
I’d take a solid WWA* type event from a storm that wasn’t supposed to be ours any day of the week.
*I understand that any WWA-type snow event with this system would likely be escalated to a WSW simply because of the ice potential.
