tornado warnings popping like popcorn in the southeast and lower ohio valley, i scanned through the severe thread in the southeast but it was not very impressive considering the amount of severe wx there, the members must be really spread out there.

Check out that debris ball on the storm north of Louisville....reminds me of June 1 over Monson/brimfield/sturbridge..

Did you really get almost eight inches of snow ? how much did you get with the upper level stuff yesterday?

1.3" yesterday. 7.1" total at my house.

I saw a report of 7.5" in Fairview.

There's only about 4" on the ground at the moment due to compaction/rain/etc....but that was using the board method.

Pretty impressive temperature bust out there today ...well, lest we have a late evening rise... Possible.

For now though, seeing 7-10F cold side busts, particularly N of the M Pike.

Interesting that the surface ridging is resistent and am noticing the 18z NAM has displaced a bit more +pp west over land as opposed to more seaward. The prior depiction promoted more llv turning into the SE. This way gives a small resistance back toward belaying warm frontal arrival. Have to think though that with said ridge all but gone entirely during the wee hours of the morning and the deep layer flow paralleling in the vertical, and no confluence N, the warm penetrates eventually for a time on Saturday prior to cold fropa..

KTAN's gone with wwa for much of the interior for sleet and zr. It would be entertaining if this lead 6-9 hours overperformed somehow.

Then we get an interesting back-side-slider S/W that passes SE of the region Sunday overnight. A few GGEM runs over recent days had this developing a quick coastal that clipped SE zones, and some of the other runs hinted. Low probability but might be interesting on tomorrow morning's run as contributing dynamics will have relayed over the denser/physical sounding domain over western N/A. And even then ...it's coming through B.C. .. not the U.S. this time.

Cold snap of sorts should last a couple of days before an impressive 2 day bout of warm departures kicks in by mid to late week. This has been flagged by numerous operational run cycles regarldess of model type. The teleconnectors are not opposed to the idea with statically negative PNA ...albeit rising toward D7-10, and pretty much all other warm indicators dominating cool ones at this time. This is "bowling" season for the next 45 days, so any time the pattern relaxes, an errantly timed N stream impulse could get pinched/severed. Anyway, not sure the warm can last beyond a 48-60 period given to the trends of the operational runs compared to their ensemble means.

I don't think this recent event is the last snow we see this season - in fact, I'd be inclined to objectively make that call based purely on climo and the fact that this is only March 2nd.

It's turned into a steady light snow...tiny flakes..but steady

Might be one of those situations where the hyped up sensitivity of Intellicast type public-marketed rad products might be better than the NWS. Intellicast's national view does show a small area of reflectivity in CT... NWS does not.

clear air mode? plus its beyond the BOX scan, OKX dual -pol show the inflow off LI sound well

It would be nice to get this front end to overperform somehow... There is a small chance we get through tomorrow without completely removing folks' precious pack...
