Winter Storm and Blizzard Watches posted this morning for Thursday night and Friday.This first map (to the right) is from NWS Minneapolis' Weather Story and shows the expected path of the low pressure system heading our way the next two days. It's not a perfect path, but close enough to call it a Panhandle Low.
Embedded in the forecast map is the snowfall forecast for central Minnesota and western Wisconsin.
Water, water, everywhere... This second map (to the left) is from the HPC and shows the Quantitative Precipitation Forecast (QPF) map for the next several days.
It's easy to see the large swath of red on this map, meaning over 4" of rain is expected from southern Lake Michigan down to the Red River of the South. They've been having terrible flooding and simply do not need any more problems.
We do not have as much forecast for us, but we do have a relatively large amount of liquid precipitation forecast for northern Wisconsin (up to 1.81" of liquid). Temperatures are expected to remain cold enough over the Lake Superior region, meaning that it looks like whatever falls from the sky will be in the form of snow.
Probabilities of snow amounts. This third map (to the right) is from the HPC and shows probabilities of receiving at least 4" of snow and at least 8" inches.
A large area has a good chance of receiving over 4" and a large chunk of northeast Minnesota and far northern Wisconsin could see 8" or more.
Details will be tweaked over the next two days, but Watches are beginning to be issued. This map (to the left) shows Watches that have been issued from NWS Duluth concerning the snowstorm on Friday.
Blizzard Watches have been issued for far southern St. Louis & Carlton (MN) and Douglas (WI) counties for up to foot of snow with winds gusting up to 40 mph off Lake Superior.
Winter Storm Watches have been issued for the rest of northern Wisconsin and parts of northeast Minnesota.
The forecast amount of snow will likely be changed a bit in the next two days, but it looks like at least 6 inches is likely.
Addendum. Just after I published this post, NWS Duluth released their daily Weather Story (to the right).
10 to 14 inches across northern Wisconsin?!?! Are they bumping it up a notch? What happened to 6 to 12 inches?
That wasn't enough??
I will try to be patient while I wait for the afternoon discussion, I'd like to know what their current thinking/reasoning is!
Now we need to watch how the expected amounts change over the next few days. More snow? Less? More? More?
We will also have to see what the surround NWS Offices are thinking and if they begin issuing any Watches today or tonight.
Snow across northeast Wisconsin last night.Here is a screenshot this morning from Oshkosh on OSNW3's weather webcam. On the fresh snow I see footprints and a missing snowboard :) As well as some puddles in the backyard across the fence.
I know rain and snow moved across eastern Wisconsin last night, but from the look of things, some of the rain turned over to snow in the Fox Valley. Farther north it looks like precipitation began and ended as snow.
Snow amounts overnight.The map (to the right) is from NWS Green Bay's Coop Observations and shows how much snow fell across the region overnight. It looks like Florence received the highest amount in Wisconsin (6.3" snow) and up to 8" of snow is reported on the ground across central locations of the UP.
We had a chance for a little snow from this system across the south shore of Lake Superior in northern Wisconsin, but the snow didn't make it far enough west to hit us last night. However, I did get a light coating of freezing drizzle.
There is a chance of severe weather here in southern Wisconsin Thursday and especially Thursday night!
ReplyDeletethe SPC put us under a SLIGHT RISK OF SEVERE T-STORMS!
10-14" of snow? REALLY ????
Cool Scout! The SPC has between 5% and 15% risk of severe weather across southern Wisconsin. At the very least, you should get some thunder and lightning - I'm jealous!!
ReplyDeleteYeah, it's looking likely that we'll get quite a snowstorm up here. It's getting a little late into the season for such heavy snow. I'll blame Global Warming :p
I think I'm under the 15% !
ReplyDelete45 mph winds?!?!
I was hoping from some more snow as well... but the amount we received was enough to get me excited. It was a gorgeous morning out over the lake. I snapped a few photos, and will post them somewhere as time permits.
ReplyDeleteThis approaching storm could be a dandy! With all the predictions you specified in today's entry... it will be easy to notice any fluctuations in the forecast. I like that. I have often thought about attempting some quality ratio between forecast and actual, but it never got off the ground.
I enjoy watching the snow pile up at Athelstane Weather Snow Cam. It's a superb setup! The combination of yesterdays and todays Snow Cam will be a good view.
Looking at the info from NWS Milwaukee, it looks your biggest threat is heavy rain across the south. 1 to 2" of rain?? Aren't you guys wet enough?
ReplyDeleteIf everything continues to line up, the way it looks now, there might be blizzard conditions up here. It looks like winds will be howling off Lake Superior (from the NE) as the strong low pressure approaches. Yeah, the south shore could see gusts up to 45 mph.
I'm in a slightly protected spot, but my terrain does slope down to the east and northeast towards Chequamegon Bay. If the winds are right, I might feel the full strength of the wind here.
I am starting a mental checklist, kind of what we do when severe summer weather threatens. I have 6 gallons of potable water, need to put the flashlights in obvious locations and collect the candles. And make sure the batteries are charged in my scanner... it's nice to hear reports to the County Emergency Manager of trees down and power outages.
Geez, that's a lot of white in northern Marinette county. Yeah, Athelstane's weather site is pimped out. Someday...
ReplyDeleteI love the Meso Map - wish I could do that for my part of the state. More to add to my wishlist of fun weather stuff :)
Looking forward to photos of the Lake!
I hope I get my CoCoRaHS rain guage before Thursday...I want to see how much we get exactly!
ReplyDeletescout, I hope it arrives today!
ReplyDeleteI guess the photos aren't as neat as I had thought when I was taking them. I am a subpar amateur photographer at best. Nothing more! Today's photos.
