Sometimes. It definitely doesn't hurt. You near Adirondack drive?

Righteous poundage here. Gonna miss this band after it moves through.

3-6" in 12 hours is advisory criteria for OKX. If its going to be 6" they have a little wiggle room, but basically 3-6 already is considered advisory snowfall. For straight snowfall, need a minimum of 3" for advisory.

Smithtown 3.3" as of 1PM. 0.6" in the past hour. Very variable intensity of snowfall. Large flakes now with some rimed flakes and I think a few IP but not many. 26F

That's what I'm hoping. The models support it. Since there are differences in teh timing of the best lift / heaviest snow with what's actually happening, I'd assumthere will be some variation in mixing too, but overall the outcome might be similar. Some IP is supported over the next couple of hours. The sleet to the SW might only make a little more progress before backing off. We'll see.

Smithown. 2.7" as of noon. Temp 25.8 Heaviest snow of the day at the moment. Not quite heavy based on visibility, but big fluffly efficiently accumulating flakes. Had very light winds and then a sudden rogue gust of wind blew tons of powdery snow out of the evergreens and filled the air with thick snow.

I'm up by 25A and think we'll probably get by with just enough IP to be a curiosity. A short window for a little mix over the next couple of hours and then back to snow and beyond that most mid level warming above 0C will be minor and masked by little if anything falling. In other words, I don't see mixing mattering here, although I suspect there will be a few ice pellets.

That makes sense. It's consistent with the 3k NAM forecast soundings. Just barely flirting with 0C at NYC at 17z. Basically isothermal between about 750 and 800 and not enough of a nudge above to melt anything. Best chances for a few IP would be around 19z (probably S/IP mix) and then quickly cools it just enough to be all snow with any decent lift. Assuming the forecast soundings are spot on. I suspect there are posters who refer to the p-type maps as "soundings" but I can't be sure.

Plus, at least part of PHL CWA has different warning criteria. This is the 12 hour criteria:

I must be getting old, or maybe not old enough. I thought that was Walter Mathau.

Gesundheit!

0.84" rain in Smithtown. We cut the snowpack almost in half since yesterday morning. Was 12" Monday morning, 9" this morning and we lost another 2 or 3 inches under the Saharan sun this afternoon. No bare spots here, there are some on the sides of Main Street down in town. I was down in Islandia this afternoon (near the LIE) and there is noticeably less snow there with bare spots.The good news is that there is plenty left on the north shore to freeze into a nice solid base waiting to get covered up with Thursday's anticipated snowfall. I'll be back out on the skis soon enough. The bad news is I'm supposed to be leading a completely filled group hike in the Catskills on Thursday and unless there is a cosmic shift in this evenings guidance, I'm going to have to cancel it due to expected travel conditions, especially for the downstate folks.

Down to 31.6 here with light drizzle / freezing drizzle. It's the first time since midnight that the temperature has been below 32. Not really freezing on most surfaces, but the snowpack which was quite soft earlier has a very light crust on it now. Pcpn very light atm. Smithtown, NY

Little Rock's record low temperature for February 15 is 13 set in 1905. Currently they are reporting 9 degrees with heavy Snow. 32 with light rain here.

Event total, Smithtown, NY = A trace of sleet and freezing rain. Liquid equivalent = Trace

Min/max here since midnight is 25.5/27.8. Narrow range with obviously still some CAA at the surface. Currently at 26.2 so it's fallen off a bit from earlier.

Worth noting that the first week of March 1969 featured 2 additional snowfalls that totaled 5.6" in Central Park, but 10 - 15" across Suffolk County. Bridgehamton recorded a snowdepth of 13" on 3/7/69. It was definitely a period that favored areas to the NE of NYC as you mentioned.

I went against the grain and put the weather channel on during the 2/1 storm. There was a live shot with one of the TWC woman standing in one of the squares in Manhattan and very clearly a rat scurrying around on top of the snow right behind her. Great stuff and I wondered if anyone else noticed it.

I don't want to loose power for a week in the dead of winter. However an ice storm would be cool. Make lemonade.

Northshore Ski Bowl was open for business this afternoon and evening. Backyard skiing with a few inches of powder over a 12" base. I will learn to ski those trees, I will learn to ski those trees, I will learn to ski those trees...

Good catch in the rain gage for a change with no wind the other night. 2.1" snow melted down to 0.17" liquid which is a little over 12:1. Was great skiing on it yesterday.

That's supposed to be z's, not 9's. The observer was sleeping instead of measuring snowdepth.
