December 12th Clipper

Ahhh the benefits of a +PNA. Anytime we see positive height anomalies in the western U.S. it heightens the risk of snow for us on the east coast. Why? Because as long as the Polar Vortex is on our side of the continent then pieces of upper level energy will break off and dig southward into our area.



Notice this new piece of energy in the Midwest - riding the western ridge - moving in our direction. It's a fast moving piece and originated from the Arctic, hence the name Alberta Clipper.



For everyone to see snow Tuesday we need this clipper to track further south than where the GFS has it. Notice the low pressure on this image is located over western NY. Heights rise ahead of this low so the coast rains while those N&W snow.



The EURO looks like the GFS. Same for the NAM.

Let's see if this trends colder for coastal areas in the next 48 hours. But those N&W are in line for a 1 to 3 inch type snowfall Tuesday morning.

LETS DO THIS!

National Weather Service has snow for me Monday night a community 1 to 3 inches before changing to rain and ending on Tuesday after that hello to Winter Wednesday's high is only supposed to be 25 degrees and Thursday a high of 32 degrees brrrrrr

Nice let's hope it's all snow and not too much today's melts. As long as it's not snowing midday Monday as I'm go be taking a drive up to CT. Then I'll be there till wed so it can snow all it wants Mon night Tues.

Monday NightSnow likely, mainly after 1am. Mostly cloudy, with a low around 26. Calm wind becoming southeast around 5 mph after midnight. Chance of precipitation is 60%. New snow accumulation of less than one inch possible.

TuesdayRain and snow likely before noon, then rain likely between noon and 5pm, then a chance of rain and snow after 5pm. Mostly cloudy, with a high near 40. South wind 6 to 9 mph becoming west in the afternoon. Chance of precipitation is 60%. New snow accumulation of less than one inch possible.

for me

We should do OK with this event north of 84. Looking like 1-3/2-4 type event right now. Hopefully things trend south in future runs.

So I see this is no longer on the snow index so I guess its no longer going to happen?

jman i think it will be a north of 84 system will see but not expecting more then 1-3 up here.

Rain for most of those in the area. Northern HV/NE PA could see a light snowfall. NJ(those who get precip)/CT are rain for this event.

Possible caliper end of week Thursday Friday night high rstio

3-5” forecast at mom and dads up in Ulster County. They got 4” the other day. Build that snow pack baby.

They're lucky. I'm in Dutchess County about 20 miles north of 84 and the forecast is only for about an inch because of too much warming in mid levels causing mixing. Maybe later in the week we get another chance of some light snow.

Looks like this will be a warm event for most

Should their be a thread for 14/15 clipper

It is 4:15 am and the temp is hovering at 31. It has been steady at that temp since 6:30 last night. I would rather see it go lower for snow or higher for rain than sleet. Looks like it will be nip and tuck up here for road conditions. NWS has it one to four inches up here but I think it will be mixed and nasty. We'll see. What am I doing up so early? Dog patrol.

And here we are an hour later at 5:15 am and it is lightly snowing up here in northwest Orange county with temp at 31. Emphasis is on light.

My local botched it. Said 2 inches, we got nothing...
