NNE Feb 24-25 Secondary Cyclogenesis and Upslope Obs

[dendrite]

Got to be a warm layer in there, sleet mixing in.

Yeah, I think it's time to buy the warmer aloft guidance. Hopefully it can still end as a dynamic couple inches of S+ here. You should be fine soon though.

And after I say that I peak outside and it is pouring heavy snow/sleet. lol

You may be IP for a while, those cells near Albany have to come by too, but the air aloft is cooling off. You and bow are likely on the line with this. Could be like 2-3" vs 6" in a matter of 20 miles or so.

Yeah it's going to be one of those deals for a couple of hours. The heavier echoes will probably flip me to bursts of S/IP and then the lulls to some light R/L/IP.

I'll resign myself to enjoying the zr. Anything more will be a bonus.

[Organizing Low]

Underway here, Starting out as snow here -SN, 34.9F

go time!

540 decameters to 522 decameters in 6 hrs is pretty darn good. For those who might not know what it means, it means height falls are very impressive with a combo of strong vorticity advection and colder air aloft combining with good lift to cause those heights to fall that quickly at 500mb.

[CoastalWx]

Most of that height fall is from PVA. With that, you are going to have rising air big time.

Whip out the QG height tendency equation and throw around some Laplachians.

from about 3:45 at my parents hood in ottawa

some dogs and people in the distance

snow, notice the speed sign 2 posts down

Awesome. A little better pictures than I can take of my zr.

[Snow Bow]

Seeing a few heavily,heavily mangled flakes making it down at this time. Only way I can tell is the rain/sleet falls straight down and these "flakes" have a different trajectory.

[powderfreak]

Awesome Organizing Low... how much so far dude?

[wxeyeNH]

30.5F moderate snow. After sleet/snow/sleet/snow seems that 100% snow has taken over. Very large dendrites. Only 1/4" so far as sleet kept compacting. Now I should build snow depth quickly.

[moneypitmike]

I don't think we've had any sleet today. A few flakes in the mroning, and then zr since. Coming down heavily for the last hour. I think the wind will end up being more notable for us southerners than the wintry qpf.

[powderfreak]

This is some very heavy snow falling right now... wow.

Looks like fog outside. Just pouring snow. I cannot imagine how fast this is pile up 3,000ft above me right now.

[OKpowdah]

Check out the exploding band in E PA. Definitely associated with the cyclogenesis near Delmarva now

[MaineJayhawk]

Picked up 0.3" with that initial burst.

Congrats--good stuff!

[TOOTH]

Its been snowing at Sugarloaf for awhile now. About 2-3 hours. Everything is well covered in the new fresh snow. People are so happy up here. You'll never see happier faces than at a ski mountain bar when its snowing hard all night.

[OKpowdah]

Strong frontogenesis now from VA into PA

[Snow Bow]

30.5F moderate snow. After sleet/snow/sleet/snow seems that 100% snow has taken over. Very large dendrites. Only 1/4" so far as sleet kept compacting. Now I should build snow depth quickly.

Probably have a nice webcam shot tomorrow at your place. White birches bent over pretty well I bet. Still wasting qpf here for the most part but the grass has enough sleet to be white and the pavement enough to feel when walking on it so if/when it switches over to snow it should accumulate pretty quick. Especially with the precip rates

Moderate to heavy rain in Keene ... very close to freezing. We do have a layer of ice out there right now

[powderfreak]

Holy crap... this must be 2-3"/hr stuff. This is nuts.

There is a noticeable amount of more snow out there than there was 15-20 minutes ago.

Temps creeping ever-so-slowly upward here, Sam. Up to 30.9--up about .5* in the last two hours. Would rather be inching downward, but I guess the atmosphere has other plans.

I laughed when I read this because it's such an ambiguous subjective observation, but I know exactly what you mean! That point when it's coming down so fast that you can see the difference in a short period of time; it's cool to see

Sleet or snow?

Mike that's actually to be expected as the temps just aloft are milder. Temps from 850 and up are cooling.

Definitely the most impressive storm of the year since the Halloweenie bomb. The moisture streaming in and causing the radar to blossom over MA and heading north is quite impressive. If only we had an -NAO like last year to push this couple hundred miles south But I'm happy to see that the ski resorts should really cash in.
