I think if we agree that model prognostics have been terrible even just a day or two out we can still hope this week is not going to a total rain fest. If anything the Nam depiction of a fairly dry Tuesday is open for an option as well. Link to comment Share on other sites More sharing options...

We just don't know what will happen, and much is still on the table. Trends aren't good, but there is still hope given how close we are to the boundary. Jns said it well earlier. With a stout HP to the north and no bombing LP w/ easterly fetch screwin our thermals, I think this on has a chance to go trainers way.....south and progressive with boundary somewhere in SEPA. EVERY model has tuesdays LP below MD line and far enough that the HP Cad feature (which we often know is late to show on models) ends up trending better for us. Just another hunch I'm goin w/.

Jns2183 Posted February 14, 2021 Share Posted February 14, 2021 The lows going to ride the boundary. Unless that low is tracking across southern pa with a high to our north and our vulnerability to CAD, I can’t for the life of me see a low tracking south of DC, a weak one at that, is going to send a driving rainstorm through Harrisburg. This has ice written all over it. 1 Link to comment Share on other sites More sharing options...

CarlislePaWx Posted February 14, 2021 Share Posted February 14, 2021 Thursday's storm on the 18Z GFS is pretty depressing. No snow, a little sleet, a few tenths of freezing rain, then a lot of plain rain with temps shooting up to 50. Then what's left of the arctic air finally passes through here later Friday into next weekend, but by that time all our snow has washed away (especially LSV), and maybe even further north. I'd love to say that it's still 5 days away and there's plenty of time for it to change. But with the eastern side of the trough to our west I can see how the storm would come up west of PA. I'm not giving up just yet. Link to comment Share on other sites More sharing options...

MAG5035 Posted February 14, 2021 Author Share Posted February 14, 2021 Been busy and mostly away from the computer good part of the day. Was a nice freezing drizzly 21-23ºF here today. I'm still not really sure what to make of the precip type situation with this. It seems like models have weakened the portion of the high pressure stretching north of us over to Quebec to a degree. Really been making this more of a straight-up gradient vs much of a traditional CAD wedge with Western/NW PA in a much better situation than the LSV or even the central counties below I-80 currently. Track of the surface low continuing to be mostly under us would figure to support more frozen. Kind of suspect about GFS and NAM pretty much routing sub-freezing surface temps out of all the Sus Valley. Euro is simultaneously the coldest column and iciest outcome freezing rain wise. I don't understand why it's still printing out such a big stripe of ZR, especially in the central counties. KAOO at -4ºC surface, -5ºC 925mb, and -1ºC 850mb at Hr 66 after 0.3" of ZR from 60-66 is not a ZR profile, no way. At least the thermals on the warmer models make a bit more sense vs the p-type. C-PA is right smack in the middle of the baroclinic zone and potential transition zones and determining where everything's going to setup is very difficult at this point. I still lean to the colder end of the spectrum and it definitely appears that CTP does too. Just something about that low tracking SE of the region with plenty of surface to try to press and bleed in. However, the aforementioned high pressure appearing a bit weaker on the end of the "banana" that stretches over to Quebec would seemingly limit driving down a CAD wedge east of the mountains to hold in the LSV SE of I-81 later in the event. On the other hand, models like to underestimate the CAD. Going to have to monitor how temps go tomorrow and how that front running wave of precip tracks Sun night into Monday ahead of the main wave to get a better lock on the positioning of the temp gradient. 2 1 Link to comment Share on other sites More sharing options...

I'm not giving up just yet. Thursday was actually the one I was more worried about cutting/p-type issues vs the current upcoming Mon/Tues event . The current system is occurring in the middle of a seismic shift of the NAO and AO neutralizing and possibly going somewhat positive from being like -4 and -6 respectively. With the EPO/WPO tending positive, PNA trending positive, and no intense NAO blocking to counter...our luck is probably going to run out soon with our nice run with a lack of major cutters.

canderson Posted February 14, 2021 Share Posted February 14, 2021 My parents’ grid forecast in northeast Texas is NUTS. Please pray for Texas. They can’t handle these temps ask the infrastructure and houses can’t handle it either, or the snow/ice. Tonight A chance of snow and sleet, mainly after 4am. Mostly cloudy, with a low around 19. Wind chill values between 9 and 14. North wind 10 to 15 mph, with gusts as high as 20 mph. Chance of precipitation is 40%.

BTW, great convo in here while I was gone. Were starting to chat it up like the MA thread. Well done. Yes, This!!! The second wave that was supposed to hit us with another round of snow on Friday actually ended up SOUTH of DC! Even today, this minor event a few days ago had several models bringing 1 to 3 inches of snow from I-81 on to the northwest. As of now, no significant precip made it north of Baltimore and it looks to remain very weak & be almost a non factor outside of freezing mist. To your point, we have 2 days to go to watch this relatively weak low that is forecast to stay to our south weaken even further. Perhaps it will pass a little further to the southeast to get more of us, especially near I-81, into more snow/sleet vs. freezing rain. We are not too much of a shift away from improving the outcome of this storm. 1 Link to comment Share on other sites More sharing options...
Blizzard of 93 Posted February 14, 2021 Share Posted February 14, 2021 Here is the 18z EPS low track clusters. Beautiful track with the low staying to our south & east with High pressure to the north & west... I think this should be at the least a front end thump of snow followed by a prolonged period of sleet/freezing rain for my backyard just outside of Harrisburg. We are in prime climo now... this should work. Link to comment Share on other sites More sharing options...

pasnownut Posted February 14, 2021 Share Posted February 14, 2021 0zs not lookin good for Tuesday so far so I went and looked at tellies as I had some time to dig a bit. AO spike and NAO to +1 ish and IMO look to be the likely reason for storm track heading west for this week as a result. That said they look like they may head twds neutral starting later this week so I’m hoping prime climo can help us as we get beyond this spike. I now fear this week may trend worse instead of better and not sure things can stay under us. Sure hope I’m wrong but we know how hard it been without the NAO and we’re losing it. Hope he comes back soon. Boo Link to comment Share on other sites More sharing options...
