The Para GFS still wants to swing the trough through. Not saying it's right, but was reading the AFDs from Grand Junction this AM (never hurts to dream of cool and snow, right? lol) and they seem somewhat skeptical of the Euro's cutoff solution (not throwing it out for sure though). Maybe this system flip flops in the 5 day window and turns out a little more progressive? It's 2020, so probably not, but I guess it is still on, at least, the edge of the table, that the front might get more of a push. I'll take any damage high latitude energy can do to that Atlantic High.

Hopefully it makes it. I'm starting to get worried that it is going to get hung up on the western edge of the Atlantic high. A few days ago it was plowing through on both the Euro and GFS, but it seems to be trending to want to dump more west now on both. boo At least it looks like a certainty we get a mini humidity reprieve this weekend.

Hopefully we get a small taste of it soon. Really hoping Isaias can help pull a trough through for dewpoint relief. It's like walking out into a swimming pool when I go outside, lol

It completely died before it made it to my place in Morgan County; I didn't even see a drop of rain. Some nice wind gusts as what was left came through, but that was it.

This convective system looks pretty healthy to me, compared to the CAMs anyway: Good and sunny upstream too, between it and me, although beyond that I'm not too good at ready the mesoscale analysis pages for severe/ strong storm parameters. To me it looks like it will make a nice charge Paris -> Nashville -> Crossville -> Knoxville

Got some pea sized hail with this line as it is coming through Morgan County

That plateau one is about to hammer me. Looks like it was bowing out a bit the last few NEXRAD frames

Sorry the above should say glad there's **NOT** a ton of sunshine.

12z new HRRR4 or whatever it is now is throwing some sort (I say that because it has a little black swath overhead) of severe storm right over my head at 23 - 0z this evening. Also popping some CAPE and decent (300 -occasionally 400) helicity values in my neck of the woods. 14z old HRRR looks similar. Not sure it will make a difference, but glad there's a ton of sunshine in sight right now.

There's a storm in N AL that's looking healthy.

We hit about 30 and a couple of basil plants bit the dust, but surprisingly the tomatoes look good. This is the first year we've owned a house and this one came with a garden, so will be interested to see how all this does.

Yeah same here. Lucked out with some heavy rain to knock the pollen down though.

Thanks Jeff and Calderon for the replies. McMinn, sorry about the outbreak word, I was probably too loose with that as far off as things are now. It is 2020 after all though, so my mind just went to worst case right away, lol. Yeah, hopefully something kills this threat Sunday AM, no one needs power outages and other major infrastructure problems right now.

This Easter Sunday outbreak looks like it could be ugly to me on the Euro. I don't know very much about severe parameters or exactly how ugly, but as Webb's cyclone map that Windspeed posted says, one look at that is all I need. I am not a fan of storms moving SW -> NE with a strong upper low moving over the bootheel of Missouri, since that can send them right up the river valleys in East TN with a lot of shear. Most damaging storms I can remember have that motion. Looking at Pivotal soundings, still looks like most of the worst is S and SE of east TN, but all I'm going on is the "threat box" if that is what it is called, where it tells you the possible wx threats. Most soundings over middle E TN give a "Marginal Severe" result, with "Marginal Tornado" nearer Nashville, but near Chatt it is giving a tornado result, with storms moving up the TN river valley near the mts. Euro suggests that there could be a bigger line/ clusters of cells moving through first, and then more with a secondary line of discrete cells as the front moves through. What do y'all who know a lot more about severe weather think?

Morgan county sheriff is reporting that the NWS has confirmed an EF0 in western parts of the county. I'm guessing it was what was left of the same cell when it got here.

Yeah I woke up about 2 to some critter scratching in my attic and decided that maybe I should check out the radar. I saw what was going on just east of Nashville and then logged on here and saw what y'all were saying and tried to stay awake until it got closer, but fell asleep until 5 AM. By then the main storm had moved just north of me and the smaller ones were rolling through. Freaked my dogs out pretty good (and me until I saw that the worst on was east of me), but thankfully no major problems in my neighborhood this AM.

Def. looks like a healthy cell right now in S. Illinois

Thanks @weathertree4u @nrgjeff and @Windspeed for the thoughts on that guy. I saw that Masiello followed him when he created his account, so thought at that time that maybe he had some good info. I suspected he was trying to sell the low solar = better winters or hurricane seasons, but he was pretty obfuscate about how he did it and I just couldn't make heads or tails of it.

Same here, lol.

Anyone want to take a stab at deciphering this guy?

Overnight Euro OP looks pretty good for y'all in terms of its pattern. As is my custom, here is some random map that I don't quite understand, but since I'm still paying these people for access to their stuff, might as well use it for something.

I don't think it is off topic at all @Save the itchy algae!. Good questions and a fair point. I think it definitely is, as raindancewx states and you suggest, "relative" given the major recent losses in sea ice up there. I had actually not looked at it and just from hearing what people had been saying, assumed the ++++AO and +++EPO had to rebuild quite a bit. However, sho nuff, you're right. https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/ Since it was in banter and raindancewx didn't cite sources, it could be that this article: https://link.springer.com/article/10.1007/s00382-017-3618-9#Sec15 was the one he was using for the claim (conclusions from that study): The spatial pattern of those CI persistent anomalies that lead the NAO by 1 year is quasi-annular about the Arctic-high latitudes coast, extending over the West Baffin Bay-Davis Strait-Labrador coast and the North-East Okhotsk sea (with positive anomalies leading the NAO positive phase). The maximal phase of this co-variability is triggered when a high pressure anomaly develops 1 year before the NAO+ (low pressure for NAO-) over the Central Arctic extending over North Greenland-Canadian Archipelago-Baffin Bay with centres also over the Laptev Sea and North Barents Sea. This “Arctic bridge” appears as a pre-conditioning feature of the maximal NAO phase, being systematic under transient climates. Its role is linked to cold advection over both: the North-Western Atlantic and North-Western Pacific with evaporative ocean cooling, low pressure formation and persistent latent heat advection over the mid-latitudes land. So a persistent, annular, negative meridional thermal gradient is achieved about the Arctic coast, leading positive vorticity over Central Arctic the following year (when leading NAO+). A mode of CI variability captures this pattern and is leading the NAO index by 1 year, having similar spectral properties to the NAO index. The highest leading correlation of this mode is obtained over ([35°N–90°N]), domain that couples the Arctic with the high-latitudes. Another thing to consider is that the NAO is measured at sea level, not higher up where we usually want it for blocking and I'm guessing most researchers, even if they like snow like us, have to go by how the measurement is taken to get their results published. While he may be on shakier ground concerning the sea ice, there has also been talk of the lag after the solar minimum producing an NAO, so I thought I'd look at that too. Probably the most famous once of these is 2009 - 10: and here is the solar plot: That hypothesis also checks out in 1998 or so: It gets less evident in the late 80s though: As you go further back there is a correlation again, but that was also with an favorable AMO, so that could have had a say too.

You severe folks can correct me, but this looks to me like it has severe potential written all over it:

Yeah I think I it’s just going to depend on where the firehouse sets up. It was showing 6+ in some places south and west. Not a guarantee, but I’d say there is a potential to overperform
