I guess the point of my post is that this is not a typical Gulf low and that this really is a bit of a hybrid overrunning situation with potential big changes last minute. Again, I think we are dealing with subtle details. This is definitely an overrunning event with a coastal component that could produce or not. If the coastal component produces it than prolongs the event and not a quick hitter type of form that Horst was saying. Link to comment Share on other sites More sharing options...

pasnownut Posted February 16, 2021 Share Posted February 16, 2021 thru 60 GFS ticks southeast w/ best accums but gives LSV the wiggle room it needed for tomorrows north jog. If this look holds tonight, I'm thinking this one is a safe bet for down here in southern pa. 540 came south a bit as well. Little colder is nice and needed and might help w/ ratios a bit.

I guess the point of my post is that this is not a typical Gulf low and that this really is a bit of a hybrid overrunning situation with potential big changes last minute. The bigger concern I have for especially the LSV wrt to some mixing later in the storm deals with the mid-level features at 850 and 700mb. The 850 low and 700.. trough are based west of the area. Fortunately these features are weak because a more dynamic phasing storm would assuredly be cutting west given 500mb positioning of the mean trough still over the middle of the country into Texas. Here's the 500mb mid-storm via the Euro. You wouldn't think at first glance CTP (or southern PA here in the Euro's case) is in the midst of getting a significant snowfall but thats the magic of when the features below 17k feet (500mb) are at least somewhat favorable and there's cold air. This isn't the first time we've played this game this winter either. Now going to show what the latest 3k NAM had with it's mid level features. The NAM is definitely on the most amped side of guidance, but same general idea is applying to the other guidance as well. 850mb heights/wind 850 temps First off, you can see the big difference between this one and the last storm... where the 50-60kt+ jet is nosed over SE VA and the Delmarva instead of right directly over PA like last night. There is some southerly flow into PA (enhanced a bit on the west side of the Laurel's) but not the major jet that torches the layer. That big arrow i drew doesn't show it well but the streamlines show that flow turning back a bit toward a due southerly flow over the Delmarva keeping the 0ºC line somewhat close. But overall, that level is okay for us but we don't want to slow down and amp this storm up much more or your going to direct that southerly flow more towards southern/southeast PA. Now 700mb winds/heights 700mb temps This is the level (and possibly somewhat between the 850 and 700mb) that I'm most concerned about for mixing here in our region. You can already see why the NAM has so much sleet as a pretty strong 700mb jet runs through the Mid-Atlantic into PA.. There's going to be some significant WAA in that layer either way (which could cap snow ratios to a degree) but that 0ºC line is teetering near the LSV at 48 when the bulk of the precip is happening. Above 0ºC 700mb air does work into roughly the SE quarter of PA by hr 54. Now as I said..the NAM is generally the most amped with the features I pointed out right now, but consider where we ended up last night. WAA aloft ended up being so strong that even the counties in the north that we're supposed to still 6+ of snow at the beginning of yesterday ended up not seeing anywhere near that. Now let me add the disclaimer that this event should drop some nice snow up front for everyone. With that said, obviously my concern is more robust warming aloft than even the NAM has modeled... especially at 700mb considering how far west the low feature is. You get that sneaky thin area up somewhere between 700-800mb of above 0ºC air and suddenly your pinging away. So def something to keep in consideration. 4 3 Link to comment Share on other sites More sharing options...

MAG5035 Posted February 16, 2021 Author Share Posted February 16, 2021 Temps already back to 24°F here with some fluffy upslope snow showers starting to get things covered up again. Spent enough time above freezing this morning that ice is mostly off the trees. Was hard to measure. I called it about a half inch of sleet which combined with the freezing rain made quite the ice layer on the snow. Actual ice accrual on trees and such looked fairly similar to the mostly ZR event I got at the end of December (which I measured 0.2”). Snowpack avg depth after the ice is about 8-9” with as low as 4” and as high as over a foot. 1 Link to comment Share on other sites More sharing options...
Cambria County Wx Posted February 16, 2021 Share Posted February 16, 2021 After getting up to 37 this morning and melting some of the ice, it quickly got cold and windy here about lunch time. Like clockwork the upslope snows kicked in and picked up a fresh .5 - 1 inch of wind blown powder. Roads are getting rough again and the temperature is 19. 2 Link to comment Share on other sites More sharing options...
