Valentines Weekend Snow


Tony

Recommended Posts

Just looked at my weather apps, 60-70% chance of snow Friday and Friday night, 30-40% chance Saturday night to Monday morning.  Appears snow is likely Friday, amounts still in question depending on model.  NWS still waiting another day or two for specifics on the 2nd wave Saturday night to Monday morning, though I think that could be pretty good unless it gets suppressed southwest of me.

Nothing really but it would be nice to get a warning type snow while we have this artic air in place. I guess I'm ready for a biggie or two...guess I'm being greedy but oh well!

If you're in Chicago you just had a Warning storm 10 days ago right? I may be the furthest north poster still waiting..

What has been odd lately, is how close Accuweather has been for snowfall predictions.  Typically it starts out high, then comes down to more reasonable levels when the storm is closer.  It was spot on with the big storm 2 weeks ago, and was almost exactly on last weekends multiple waves.  I just checked, and it has my area for 2-4" on Friday/Friday night, and 4-8" on Saturday night/Monday morning.  I would say the 2-4" looks good, the 4-8" for wave 2may be a little high, but ratios could be 20:1 so I guess it is possible.  I'll keep track and see if they are correct.

Nam still looking good for this weekend. Also showing a nice fetch off the lake for western shores of NE IL starting Thursday

That lake band looks rather interesting.  It could produce some intense rates if it holds together.  Similarly, this type of band set up across the lake into W MI last week and dumped close to 6" in some spots.  I could certainly see this band over perform in spots.

Liking that it has it farther inland than you would normally see.

Omaha NWS reduced my pops from likely to 40-50% on Friday/Friday night. Says 1-2 now vs 2-5" in earlier forecasts. Bitter cold and hope for a nickel and dimer event....

Ready for a pattern change at this point.

Not sure why. No significant model changes, I’d still say 2-5” is a good call.

Snowfall in Lincoln, NE:

2017-18: 21.4"   2018-19: 55.5"   2019-20: 17.6"   2020-21: 49.4"   2021-22: 5.1" 🤮

Average: 26"

DMX's actually somewhat favorable for Saturday which is not the norm-

Another chance for snow is expected to evolve on Friday into
Saturday. There is not much in the way of low level QG convergence,
but we will be on the back side of the 140 knot jet streak in the
favorable right entrance region. In addition, cross sections show
good saturation in the mid-levels over much of Iowa and into the low
levels over central and southern Iowa. The lift also coincides in
the DGZ and with added frontogenesis in the 850-700mb layer and a
little more QPF, expect snow totals to be a bit higher with perhaps
a few totals nearing 3 inches over central or southern Iowa with 1
to 2 inches elsewhere. The snow should end mainly Saturday morning
as lift wanes and the atmospheric column dries out.

The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

So if that actually pans out would that not be a record amount of snow for Kansas and Oklahoma. Those are insane numbers. Also -35 wind chill Saturday into Sunday. Going to be painfully cold.

No records, but yes, painfully cold. Snowy is the good part. That advertised -13° cold night is what's going to hurt so badly. I still remember 2011. That's some darn cold air.

Tulsa AFD

(Some parts omitted...)

"Now to the meat of this forecast, and the bad news. The GFS and ECMWF have remained amazingly consistent, especially given the time range of the forecast, regarding the next storm to affect the Plains Sunday into Monday. Both models paint considerable QPF over a deepening arctic air mass over the region. Snow ratios from the NBM look underdone given how cold this air mass is, and will thus use a 15-20 to 1 ratio from the GFS/EC. Since the snow will be more powdery, winds will be blowing from the arctic high building south, and snow rates could be heavy at times, the potential is there for a highly impactful winter storm early next week. Travel could be shut down over a large area. Power outages could occur when winds pick up due to the residual ice on the lines from the recent weather. So this storm has the potential to be a big deal. Forecast snow amounts were increased."

I just compared this map to the 12z Euro and it sure appears that the pink in Nebraska is farther south than the 12z. I like it. 

Keep the south trend coming. Not sure how reliable the 18z euro is though. One could only hope. We are already going to have a delayed spring, might as well keep it coming
