Hi everyone! Just testing the chat to make sure we're all ready to go!
Testing 1 2 3... good evening everyone!
Thanks for joining us everyone - Charlene and Justin are both logged in and we are ready to start answering your questions about this latest round of winter weather.
Justin, I'll have you answer this first question.
Charlene, here's our second question
Hi Spencer, we'll start to see rain overnight in CR. Looks like it'll be mainly after midnight. At this point, the risk of freezing rain looks pretty small. If we get any, it should be brief... but something we're watching for. The good thing is that the changeover from rain to snow tomorrow should be fairly fast when it does happen... not a lot of wintry mix during the changeover.
Jacob, around and south of I-80 will be primarily rain. That's not to say there won't be some snow mixing in towards late in the day/evening, but at this point it looks like it won't amount to much accumulation. The farther NW you go, the more snow we are expecting. Everyone will start out with some rain, and then we'll start to transition to a mix and eventually snow starting with our western communities.
Charlene, this one is for you.
Lori, the freezing rain looks to be pretty minimal with this event. We should still be looking at rain and above freezing temperatures Thursday morning at 4 AM.
Bailey, While it doesn't look like Iowa City will get a lot of snow (probably around an inch of wet snow, as it looks currently), there will still be some low visibility because of the strong winds (30-40 mph certainly a real potential). Before the changeover to snow, Iowa City will be dealing with rain... probably at least a half-inch. That'll cause some street flooding where the drains are covered in snow. We'll also be watching for the wet roads to turn icy as temperatures fall Thu afternoon.
Melea, that's correct
. Overnight tonight will be basically all rain. There's a sliiiight chance of some wet snow mixing in over far northeast Iowa, but we're banking on rain. The change from rain to snow will occur during the daytime hours tomorrow, from west toward the east.
B, strong winds will be over much of the area. All across Eastern Iowa you should expect to see blowing snow. The worst will be in our NW communities as they will also be seeing a larger amount of snow falling which will significantly reduce visibilities. In our Southern communities there will also be some blowing snow and reduced visibility, but to a much lesser extent.
Chindichore, that's an excellent question. While Winter Storm Warnings are typically issued for large snow totals, they can also be issued for high impact events such as this one. Many areas are expecting 1-3", but there will be significant blowing snow as well (more than what would warrant a Winter Weather Advisory, but less than Blizzard criteria). We'll also be looking at difficult travel not only because of the blowing snow, but also because of the slippery roads. Since we're starting off warmer and rainy, this will likely wash away a good deal of the road treatments. As the cold air moves in and we transition to snow, the wet roads will become slick and possibly icy. SO because of the combination of slick roads, blowing/drifting snow, and moderate accumulations, a Winter Storm Warning was issued.
Jack, there's still some question on the eventual storm track. The very latest computer model indications are in better agreement this evening than they were earlier today (thankfully). The problem is, the rain/snow line is going to be highly dependent on where the low pressure moves, so even a 50-mile difference would have a pretty notable impact on when the changeover happens (and snowfall amounts, as a result). This is one of those situations that we won't have as high of confidence as we like to have until a matter of hours before the change to snow happens. One thing's for sure - VERY windy and that'll be an issue Thu afternoon/evening.
