AllWeather Posted March 9, 2017 Share Posted March 9, 2017 5 minutes ago, djr5001 said: I noticed same thing with 12z GFS and NAM - they seem to really struggle with being too cold for highs when we have the downsloping west/northwesterly winds and full sunshine and too warm with the east/southeasterly flow that gives us the overcast and foggy kind of days around here far too often. The one difference that I see with this event compared to February is that this one does not appear to have a warm front ticking back north around onset of precip which is what really screwed the York, part of Lancaster, and more southern areas from seeing the changeover in time. The downside to that positive though, is PWAT values for this event look to be much lower (nearly half) of what they were last month. The dynamics combined with the high PWAT are pretty much the only way that some spots around Harrisburg were able to even get close to the 5" mark in recovery of what was lost precip wise prior to the changeover. Good point. To play devil's advocate to this point, part of the reason temps may not have dropped as fast in early Feb could have been due to the higher PWAT/Td air. Drier dewps could support faster drops to wetbulbing. Current dewps are in the teens/20s. That should support faster cooling and argue against my initial theory of temps taking too long too cool. We had to wait for drier dewps to advect in. We already have the dry dewps and wet bulb temps are sub-freezing already in NW PA. I can't recall where it was for the early Feb event at this point, but I do remember sitting there hitting refresh on obs waiting for Tds to drop from the 40s to L30s overnight as the precip arrived.

MillvilleWx Posted March 9, 2017 Share Posted March 9, 2017 Euro continues the theme with a better look for the southern tier for the AM. Actually took a look at the handle of temps in the area at the 18z hour, and it's certainly fairing the best among the global models with the handling of the temps, and it still gets some modest accumulation down into the LSV and near the MD line. Down my way, it's not doing many favors and providing a sharp cut off to totals south of I-70 which has been my feeling all along. That being said, the conditions for a moderate, plowable snow are well within reason for the areas west of the 81 corridor out in the Laurels up to I-80. One of the biggest takeaways for sure is the PVA for tomorrow afternoon will come in like a battering ram and snow squalls are highly likely and could out perform the main event in some areas, at least IMO. This is fun. Link to comment Share on other sites More sharing options...

Nah, man, this doesn't work, because you consult your doctor and he starts ordering tests. One day you think you're just excited and tingling everywhere, and the next day you've got spinal stenosis and spend the rest of your life in between stretches.

I just read Eric's District 8 forecast that I can access since I was part of working with him on PennDot while I was at school. He's saying Tuesday event could easily be the big event with the players on the table. I'm very intrigued now. Link to comment Share on other sites More sharing options...

Yes. I remember with certainty that my dew was in the upper 30s and low 40s that evening. I was very discouraged when I was sitting at 52/42, knowing that we had a lot of work to do down this way. My dew right now is 26. Big difference. Link to comment Share on other sites More sharing options...

I was wondering with the temperature we're having today what we would lose, but it sounds like we may be alright. and my kid won't be leaving the Ville until 430ish tomorrow.

canderson Posted March 9, 2017 Share Posted March 9, 2017 Man this thread today is awesome. Red taggers, you guys rock. Thanks for all your analysis. Question re: Tuesday. What is in place that'll allow it to get captured in time to ride the coast to bring CPA into the snow? To me I can't see anything that doens't cause this to capture later and leave out anyone not from say Long Island northeast. I'll hang up and listen.

To me I can't see anything that doens't cause this to capture later and leave out anyone not from say Long Island northeast. I'll hang up and listen. The main driver for that occur is the northern stream vort digging into the US. If that energy can dig far enough south to begin phasing with the southern stream energy around Tennessee/NC latitude, that would allow for an earlier capture and tuck into the coast. Some models are pretty close to doing that, and even when they don't, your area still can see snow. The best shot at major accumulations greater than 12" are more likely up across NE PA up into New England at this rate due to the bombing low and increased interaction with the northern stream north of our latitude. Still doesn't mean we can get whacked like that, just probably a slightly better shot to the NE. Link to comment Share on other sites More sharing options...

I almost feel the short term guidance are sticking the heavier axis of snow to the SW now with areas out towards Johnstown getting hit good, but heads southeast into the PA line. That would be a bad omen for areas north of the pike further toward the east. You can kind of see it here on the latest HRRR. Link to comment Share on other sites More sharing options...
