My fellow Oklahomans, by the time you read this Ticker, the ICEMAGEDDON storm will
be (checks notes), well, still over a day away as it turns out. So I guess you
still have time to get to the store today, tomorrow morning, and much of tommorrow
afternoon? The storm slowed down a bit, and the models are still having trouble
figuring out what the surface temps will be as we go through the day tomorrow.
Obviously, that will make a huge difference in whether you see freezing rain or
just a miserably cold rain. Apparently, with the precipitation holding off until
a bit later tomorrow, that means less cooling due to the wet bulb effect (i.e.,
precip evaporating, which is a cooling process, aiding in pushing the temperatures
below freezing). So that's good news I reckon. Doesn't mean we're not going to
still get hammered either (by snow...those of you headed for the spirits, that's
up to you). We still have a winter storm for the northwestern 2/3rds of the state
(save for the western Panhandle...which is why they get a 4 on the BRAUM'S
EMERGENCY DEF-CON METER).

Most of the state gets a big fat 1 thanks to the threat of extreme snow and ice
amounts, with the addition of the remaining uncertainty of where those impacts
are going to be greatest. So we're shotgunning the threat levels. Here's are the
updated maps from your friendly local NWS offices.

The cold front that is giving us this misery (joy??) is passing through NW OK
as we Tick. And pardon my German, but it's about to get frigging cold.

With even colder air poised to rush down our way.

As we've cautioned many times, the forecast can and probably WILL change as we
get closer to the event. For better or worse. Obviously, this storm is going
to bring high impacts regardless of the fine-tuning from here on out. We don't
usually get big winter storms like this with such a large footprint of hazardous
impacts, at least this early in the season. It rivals the Dec. 2-4, 1971, and
Dec. 1-3, 2006, storms.

Stay calm, stay safe, and hunker down this weekend!
