Thursday's storm ...Rain, wind, snow and ice?

Preliminary call

Does this include snows with the upper level low? I see you have "Thursday" written so I would assume no? That upper level low has over-performer written all over it on Friday, IMO. Both SNE and NNE. All models have a nice area of lift moving through on Friday when that trough axis moves over the region.

Yes it does! That's why I asked.. You probably will see foot plus, glades FTW.

Around here at least this looks like a six hour warm advection thump: 6z to 12z. NAM has .7" in 6 hours. Then only .2" the rest of Thursday and maybe by then it doesn't matter much whether that is FZRA or PL or pure cold rain.

Lets hope that first thump can be snow or at least snow/sleet....

Unless this comes really close, we might not have enough QPF once it changes, but that will be track dependent.

Only for Thursday, not including the light snowfall possible early Friday if that's what you mean

I'm really liking the upper level low. Those seem to be over-performers more often than not. Like fluff after the synoptic storm. High ratio and usually comes down pretty hard for a time as it swings through.

12z GFS and NAM are in pretty good agreement with this feature.

You will clean up with the upper level low, Rick.

I'm telling you that's the real deal... check out the 12z NAM and GFS images I posted. Compare to this 00z GGEM. All the models have this now.

SNE has become the new MA for infighting

Can't we all just get along? lol pf, I might move up there because of your pics

Hopefully this will waver back colder/south (just a little)

We just need to avoid a disaster for WaWa. Any small gains would be huge as just a few days ago it appeared to be a major setback.

Latest SREFs seem to be hitting that FZDZ pretty hard up this way. Early Friday the probs for FZRA if a member precipitates are awfully high. Seems like that window between the main low and the next shortwave upper levels dry out just enough to support this.

could see that being an issue right down into metro boston perhaps...though hesitant to believe just how cold the LLs are on the NAM.

Hopefully we can get some gusts close to HWA criteria, dont think flooding will be an issue in most areas since the ground is not frozen.

Congrats to our friends up north, looks like some cement for the north kingdom such a better outcome than was progged a few days ago, its pretty unbelievable how much guidance has cooled over the last 4 days!

I like your map, Sam. Looks good from the current look of things.

But...................I've seen this movie before and I'm afraid of how it might end. I will not be suprised at all if I fare better on Friday than tomorrow night/Thurs. That's for many of us, I might add.

weenie flakes here in the meantime.

I agree... if I was north of the NH border I would feel better...

I see a lot of people counting on Friday :lol: ... not lol at the possibility, just at the overwhelming theme of replies to my map haha

I definitely agree that this could be a decent performer for many. These type of events usually have some high ratio accumulations.

Mid level temperatures tumble during the day Friday, lowering the snow growth zone. A period of decent omega in the SGZ moves through ahead of a spoke on the upper level low. Easily a 2-5" event, with options for much more with upslode
