Had winds gusting around 45-50 mph when the line moved thru with brief heavy rainfall. Things calming down now.

Still pretty gusty behind the front. I'm picking up gusts in the mid 20's mph range. I really wish my anemometer was mounted in a more favorable spot though--it's on top of my shed and kind of sheltered from different angles. One of these days I'd like to mount it high up on my roof peak, but that's going to require some serious preparations (and maybe a lift rental).

The line moved fairly quickly and almost off the coast.  It's currently now down to 57 here with dp slowly dropping and at 47.

wow, 73 + degrees today and the 0Z NAM is showing 4-6'' of snow  for the LV on Wednesday. Wind gusts well over 45 mph. More freaking branches to pick up from the windiest last six months that I ever seen here. Not much rain however, less than .25 in. The predicted snow on Wednesday may help with some groundwater recharge for our area and keep the spring wildfires down as the ground is almost dry from tonight's northerly winds of 35 mph, even though it rained an hour ago. 

I also think a WWA may be issued for Wednesday. The snowfall rates appear to be pretty high and may actually accumulate on the road. 4 -6 inches of wet snow on the grass and 1-2 inches of white rain on the road appears to be reasonable expectation if the NAM/RGEM model is spot on.

I recall seeing a trained spotter in Skippack report  a 56 mph gust there.  I didn't get chance to screencap their actual mPing report but it's the "55" tag in central Montco on the below map...

Agree with Mt Holly's maps. There's just no way we are seeing 4-6" like the 10:1 maps spit out after temps being in the 70's and temps remaining above freezing during the event. I wouldn't rule out a slushy inch or two though if the rates on the NAM verify. Use the snow depth maps and not the 10:1 maps on model output, it's a much more realistic outcome for this storm.

In 40+ years of driving, never have I experienced the effect of wind on a car like I did last night on the Girard Point Bridge leaving the 76ers game. The crosswinds were insane - despite the fact that there was little traffic on the bridge, I don't think anyone was going more than 45mph. Everyone was holding on to their steering wheels for dear life.

2 weeks ago this upcoming storm would have been a solid 4-6" region wide. Of course we finally get a great track and boundary level temps are scorching on top of the increased sun angle. Not expecting more than snow TV with maybe a slushy inch on the grass that is gone by the end of the day.

I believe it, those winds were fierce as the line moved through in Levittown. Easily 50 MPH at least. Luckily there's no foliage yet so damage was minimal other than trash cans strewn about.

Completely agree.

NWS knows it's winter 2022 thus it mostly only snows before 9am lol

Wednesday
Snow likely before 9am, then rain and snow. High near 37. Calm wind becoming southeast around 5 mph in the morning. Chance of precipitation is 80%. New snow accumulation of less than one inch possible.

I think I have hit my high for the day at 47.  Currently bopping between 46 and 47,  and a sun shining through a deck of cirrus, with dp 22.

ECM a hit with the frontal wave on Saturday NW of I95. Today's run gives me 50% of all of winters snow in the next 4 days :lol:

I was doing a comparison and I think the issue with that is that the "Total Snowfall" is basically an aggregate of all snow that fell, whether it melted or not.  I expect in this case (as mentioned by someone who posted in the thread earlier) that the "Snow Depth" is probably a bit better indicator of what is coming.

Right now I think the arctic wave is bogus I know I won't get 8" snow this week. That snow depth map looks reasonable for what will fall tomorrow in SEPA and Lehigh.

46F here. I'll tell ya a March 46F/sun compared to a Jan 46F/sun is night and day. I could easily go outside now w/just a flannel in the sun and be just fine. The rays are kickin. Wouldn't work that way Jan, would need a jacket.

House heater has been off since Sat night and still off (inside temp 62 w/the sun blazing through the windows) Should give me a break on my PECO monthly bill which I'll give back by filling up my gas tank...
