Mount Joy Snowman

Not seeing much model support for mid-next week but still a ways to go. Might have to wait until the clipper swings through later in the week toward the weekend.

Low of 5. It looks like the core of the cold and/or best radiational cooling stayed out west last night. I think we bottom out tonight out this way. Loving the staying power of this pack, has barely budged an inch. Talk of snow mid next week exciting as well. Onward.

National high of only 78 at a few places in southern California and low of -28 in extreme northeastern Minnesota near the Canadian border. Crystal ball says the next three days come in at an average temp of exactly 10 at MDT (crazy), bringing the monthly mean for January down to 26.5, which would be sandwiched between 2011 and 2015 for the 33rd coldest all-time. Book it.

Low of five here, as I sit up a wee bit too high on the ridge, but it looks like most spots around me hit near-zero or below. It's interesting that most of the sites seemed to hit their low pretty early in the night ~1-3am. I assume some clouds moved through. Next two nights may go lower. Onward.

Sure seems like it, maybe the next three nights. I know the initial drop can come quick right after sundown and be a bit deceiving, plus a little batch of clouds or winds can screw things up, but if I were a betting man, yes.

Last night’s low was 10 but already sitting at 11 here at 6:30. Wow.

Yeah even with the odds greatly against us for this one I'm not fully writing off anything south these days until we get inside of 72 hours, perhaps 60 ha.

The river by MDT is completely indistinguishable from the surrounding terrain. Just pure frozen tundra.

Busted high this morning with 11 at the house and 7 through the rurals. The next three nights look like the peak. Amtrak canceled its first train this morning. Streets are a mess here in Mount Joy. Love the chaos. Let’s bring on some more this weekend (I have not checked any modeling recently).

Hmmmm the 57 might be a little too wound up and have a stronger but more tightly wrapped precip shield. Give me the 81 haha.

Low of 10. These next few nights will be the peak of pipe-bursting season, keep warm everyone! Looking forward to seeing if this coastal can't get wrangled in a bit more. Probably not "our" storm but also think the possibility is there for improvements. I would have no issues with getting a few inches of fluff on the western flank if that's what it came to. Keen eyes will be monitoring.

My 8.8” of snow/sleet melted down to 1.58” liquid. To get that amount of qpf while sitting in the low teens the whole time and only come away with less than 9” is something else. Man what could have been down this way. Still happy to have a nice solid pack.

Agreed. I think you intended this message for JNS? I was the one pointing out that him doing the hourly measurements likely inflated his totals and that it should be done every 4, or as you've now clarified, 6 hours.

Yeah there are always some looney tune reports in those PNS releases but they offer a good big picture view. Aaaaahhhh so you do measurements every hour and sum them? That would explain your big total. I believe NWS guidance for snow measurements is every 4 or 6 hours, someone can correct me. Not hounding ya for doing it that way, just offering some color as to why people report such varying totals.

The radar is blossoming and it is now officially lightly snowing. Perhaps another day of putting something in the books. Love it.

Low of 14 and .1" of additional snizzle brings the storm total to 8.8". It's also snowing here very lightly at the moment so that's neat ha. Melting down the gauge and will report back later. Really looking forward to clearing the driveway sigh. Here's to keeping a keen eye on next weekend.

Or DC......or London.....or.......

Ah yes, I should have remembered Feb. of 2015, have quite the write-up about it in my spreadsheet. Should be fun to see how this stretch compares.

Was talking about that with my wife earlier, can't recall an extended stretch this cold, and the nights may be able to go even lower with this snowpack if we go clear and calm. Get ready for pipes bursting.

7pm Obs: 14/13 with moderate sleet as the dry slot approaches. Sleet has accumulated an additional .5" since 3pm, bringing the storm total to 8.7". A funny reminder with this storm has been just how inefficiently sleet accumulates. You can think you're getting hammered with pingers for hours on end and then you check and it's like half an inch over four hours or something like that haha. In any case, quite a pack we're going to have for ourselves here.

Nothing but solid sleet. Wall to wall sleet. In fact, some of the heaviest sleet of the day falling here again before it looks to shut off shortly. Wild.

The last hurrah is moving through as we speak with again mega sleet. The conditions in this denver game are insane!
