Just caught up with the posts from overnight. Things looking great for tonight and the big one on Sunday. Measured 3.8" on the board. It was still snowing extremely lightly when I measured about 15 minutes ago, but not accumulating anymore. Temp 28.2 after holding most of the night at 27.0. I like where I'm sitting for the upcoming events. Thanks to all who threw up maps. Very helpful. Edit>>Will have liquid measurement in an hour or two. Others seemed to have been around 11:1 or so.

Wow. Just headed off to bed with HEAVY snow falling. Big flakes. Dropped the temp from 32.0 down to 27.7 in only 30 minutes. About 0.6" of snow on the board and it is definitely snowing at 1"/hr rates at the moment. Will the NAM be right come morning???

The NAM says there will be 6" on the ground at MDT at 12Z tomorrow. Hahahaha 1"/hr snow for nearly 6 hours.

I think you really can throw out this run on the NAM. It gives MDT 7" of snow tonight from the clipper and nothing from the coastal on Sunday. Based on snowfall distribution it looks like it takes the low inland enough to give all of the LSV rain.

Is that good or bad? I forget what the euro look was?

Can I trust this Fri>Mon all storms total???

Lol. Sorry. This is what happens when we are tracking multiple storms simultaneously. The NAM shows it snowing again Friday night with another new 1" of accumulation on top of whatever we get tonight.

NWS disco describes it as a Miller A saying a low from the gulf rides up the coast to the Del Mar Va by Sunday evening.

I was a little off on my numbers, though it did up the MDT area to 4". Southern York/Lanco it's only 1-2". Not sure what's up with that, though, or why.

12Z 3Km NAM just upped tonight. Now gives MDT nearly 5". Woo-hoo.

Peak wind gust here for the event (so far?) has been 38.5 mph recorded at 11:00pm last night. Overnight I've had multiple gusts in the mid-30's with average sustained winds ranging between 10-15 mph for the most part. The location of my anemometer on my rooftop of a townhouse end unit is not the greatest for westerly winds as I'm on the eastern most end so I think the winds end up muted a bit. Due northerly are best as there is nothing in the way from that direction. Never lost power. Just had multiple flickers of less than 0.25 sec.

Sorry for the delay...was taking a longer-than-expected Sunday afternoon nap. The ramp-up began around 4:40 and my peak gust so far was 35mph at 5:27 and another gust to 30 at 5:46. Yeah, this seems to just be the beginning of a long night. No power problems here yet. Our electric lines are underground so we tend not to have problems hardly ever except for the occasional flicker during thunderstorms. We'll see.

The High Wind Warning says at the end of the text to expect widespread power outages. Guess that's what's happening out west and unfortunately heading our way. My peak wind gust for all of calendar 2018 was only 46mph. I guess it's likely I'm going to exceed that between tonight and tomorrow morning. Might be a tough night to sleep without ear plugs.

Yep. I was right. 3pm ob...State College wind SW7 while Altoona wind W 33 gust to 47. Get ready it's-a-comin!

I think the start of the high winds is currently out near Altoona / State College based on radar precip line. Definitely delayed/later than forecast. Looks like nothing of consequence reaching Harrisburg before 5:00pm. Temps only barely climbing. I've just made it to 40 after spending the entire night between 33 and 34 with the rain.

Sorry...never saw the movie. I was pretty sure he had to know history.

You were joking, right?

What are the details from this map? Model? Run? Timeframe?

Latest HRRR continues to give all of us freezing rain primarily between 7pm and 11pm this evening. Temp at MDT forecasted to be 29 at 7pm, 31 at 10pm, and then just touches freezing as it ends by 11pm. Total liquid dropped a bit, now down to 0.43". The worst single hour for accumulations is between 7 and 8pm when almost half of that, 0.19" falls. That does coincide with the coldest surface temp, so there could be some rapid accretion.

Super-light freezing rain/drizzle falling here right now. Temp 28.2 and pretty much sitting stable. Very light ice glaze now on my clear-vue gauge.

Nearly all of the freezing rain on that HRRR map I posted falls between 0Z and 04Z. Surface temps are below 32 through 04Z at least.

Latsest HRRR says there could be just a very tiny amount between 4 and 7pm (a few hundredths). The significant stuff arrives after 7:00pm. The late afternoon stuff shouldn't be enough to affect the roads with their prior treatment.

1:00pm Ob -- Very light snow (non-accumulating); Temp 27.7 Picked up an additional 0.3" of snow during the past hour for a storm total of 5.3". That might be it for snow. Greens are gone from entire radar.

Well, if you can believe the HRRR, with each passing hour it continues to up the total freezing rain at MDT. Only 4 hours ago it had a total of only 0.07". Now, as you can see below, it has a whopping 0.56" !! Look out this evening.

Here at noon I just measured 5.0" on the board, an increase of 1.0" during the past hour. Most of that inch fell between 11:00 and 11:30 during the super-heavy period. It's been light to moderate since. Temp has risen to 27.0 with the drop off in intensity and increasing sun angle of the day. With only blues on radar now it's going to be tough to add significantly to the totals from here. But, this is the best event of the winter for me as I was down in Florida back in November and came back home the day after the storm.
