I hate to be that guy but could there be thunder with this thing tomorrow evening? If it weren't for the warmish mid-level temps...500mb around -15*C...I would say thunder is likely with this setup. But with the upper level system so far removed to the NW, the colder temps aloft never make it here. I still wouldn't be surprised to see a lightning strike or two given the intense lifting processes in play.

Already highlighted under a 15% risk of Severe Storms Saturday. Could be our first outbreak in quite awhile as even this far the system and dynamics are looking pretty scary.

Looking longer term after Saturday the pattern will enter make or break time. A lot will depend on the MJO and whether or not the NAO can drop negative even modestly. If it does 1st half of March could be pretty interesting with a couple heavy wet snow potentials. If not and we spin back to Phase 4-6 then Winter will be staked but the pattern will still remain active but several potentially major rounds of severe storms possible through March into at least early April. Either way a long period of boring weather isn't very likely despite what the models are showing long range which doesn't seem like much.
Overall it does appear that the several years of lackluster severe weather seasons could be coming to an end this year with a fast and relatively early start.

Winter weather advisory issued starting with 2 inches of snow. I think that's a good start as they can always increase if needed.

I don't understand how the text of this forecast corresponds with 1-3" of snowfall...they make it sound like a few flakes mixing in with rain which is a terrible forecast. These point forecasts should be done away with...they create more confusion than anything.

Having an on line discussion with someone in Council Bluffs about the snow Iowa has gotten this year, as well as farther north in Minnesota.
Anyone have any insight on the flooding potential as we move in to spring? I know it somewhat depends on how quickly it warms up.

I'm sure it will happen again someday. We may be dead and gone but chances are it has also happened numerous times over the past millennium. We just will never know. I sure wish it would have waited 40 years to happen though...I bet that was really something to see! The blizzard of 79 was amazing; especially to a 14 year-old. I remember it drifting to the bottoms of the windows on my parent's house. We had new neighbors who had just moved in a month or so before. They were from Florida and had never saw snow except on TV...... They had a 5 year old son who could literally vanish in the drifts! Funny you replied to this Bruce. I just texted my mom (Marcy) about this. She remembers it. Dr. Beyer went to their neighbors house by snow skis to deliver a baby. It would be amazing to see.

NAO and AO are positive next 10 days or so...we could very well have severe storms in early March, with the end of March back to the winter like drizzly, chilly, and flurries, and many on this board will be anxious to turn the corner to Spring. Whatever we end up with, March looks to me to be a weird month.

Kaboom Epic Meh Destroy Drying cloth
Just a few words that some may not realize are actual weather terms. Anyone remember the Atari 2600 game, Kaboom? You had to use the paddle controller. It was awesome.

Having an on line discussion with someone in Council Bluffs about the snow Iowa has gotten this year, as well as farther north in Minnesota. Anyone have any insight on the flooding potential as we move in to spring? I know it somewhat depends on how quickly it warms up. I had this discussion with March Fuchs at NWS LSX. The spring flood outlook is coming up either later this week or early next week. But he said some of the numbers being churned out by the long river forecast models are eye popping.

Things look really good for whoever is on the the Far NW edge of the deeper moisture the NAM has.
For kblv the nam has over 0.5" of qpf as snow before it changes to rain.
I'll take my chances.

I think there should be more emphasis put on the intensity of the snow rate with tomorrow's event...it has potential to quickly snarl traffic with almost whiteout conditions for several hours.

I didn’t know Dave still did forecasts. It’s not bad probably a little conservative. I still like my 1-3” , I hope it busts on the low side

We were a good deal colder than I was expecting today as well. I only got to 28. I think Lambert hit 30 or 31. Point is it was below freezing. Tonight may dip to 20 to 24 and with clouds tomorrow may be a struggle to 32. So definitely been 3 to 7 degrees colder than modeled

Is it because it will be icy before and after the snow and because of the snow being heavy and wet that we are only getting 1-3 despite the predicted heavy snow coming?

Afternoon AFD says 2-3 inches with locally higher amounts with 1/10 of ice. Rush hour tomorrow evening may be nasty.
