Jan 11th-12th Snow threat is REAL


Wx4cast

Recommended Posts

SREFS our in house meso and 4Km WRF have nudged more west from early morning runs. Thinking low tracks just SE of Block Island by tomorrow early afternoon. That's a perfect track for ENY to get thumped. banding too quite possible especially over WNE. We have nudged up total a bit this AM (actually just shifted the contours W and NW) some.

Still not farenough NW for Tornado Girl but the LES behind the storm looks good for the Tug..

So far, this has been a strange La Nina this season; anyway, looking briefly at the models We could have two more systems next week one around Tue and the other maybe Fri.

I'm getting too old for this!

Another congrats to the ENY'ers!!! Andy has this covered in spades. NAM (with the final votes to be counted) looks to have basically nailed this storm from a day and a half ago, beating every other model out there. Kind of a rarity!!!

I bet ALY goes over 10" in a hurry!!! :snowman: :snowman:

Thank you George. Yes it is a rarity for the NAM but once in awhile it is good and it was good on the Fri-Sat system, too. And I agree Albany looks good for 10" easy.

BTW- Cuedos to Tornado Girl on an earlier post in this thread where she mentioned watch for things to start "earlier". Tip of the cap to you.

Here is the 12z 4Km WRF output. 24 hour total QPF for 12z Tomorrow and for the next 24 our period. Add them up for storm total QPF. It has shifted things a tick east vs. its zero runs but it too has been decent to good as of late, too.

I'm going to sign-off now. I have to head down south to get my daughter from her basketball practice then when I come back home its a very early bed-time for me. We're starting NEWS10 in the AM @ 430. (If anyone cares we'll also be streaming the AM on-line too; just go to our website).

A long day has been planned for me by the hype-meister media machine. I have to be in by 2AM the latest.

Night All, sweet dreams of dendrites!

THE HIGH SNOW RATIOS ALSO CONTRIBUTING TO THE ADVISORY LEVEL SNOWS IN THE WESTERN MOHAWK VALLEY AND SOUTHERN ADIRONDACKS TO GFL AREA. PLUMES AND PROBABILITIES FOR VARIOUS QPF SUPPORT TOTAL SNOWS AROUND WARNING LEVELS.
