SPC seems to hint at a chance of an outlook upgrade later pending trends.

Just a little humor - the CIPS analogs from the 0z run for the 24hr mark have 5/31/2008 as an analog. I mention this because a few days later that year on June 4th we had one of our more impressive severe weather outbreaks in the last 15 years. That was a lot of fun IMBY. SET THE TABLE

Dews need to come up in a hurry. We are still in the low to mid 50s for dews at best. That'll help a lot with instability. Hopefully we can advect some juicy dews in.

Yeah the most recent HRRR runs pretty much suck - just isolated activity.

Sun is out here with thin clouds around. On my way to work (currently between Silver Spring and Rockville)

Parameters continue to look pretty impressive. But sim radar is pretty weak sauce for us on most models (even the better ones @high risk ) mentioned. Still think it could go either way. I want to get excited but that's always a losing strategy around here. On the plus side - it does look pretty certain that we'll see a good bit of sun tomorrow...that's one of the factors we sometimes don't have (often).

12z NAM nest has almost nothing unless you're in extreme NE Maryland. Meh.

They certainly seemed to be before. The last year or so though they seem far more conservative a lot of times.

Maybe we can pull a miracle and keep the warm front JUST to our north. As Ian says - playing with the warm front is not usually a bad thing.

Almost seems like the trigger just isn't strong enough to get things going until you're in the area you mentioned well north. Pretty much all of our severe days have some aspect of "bust" written all over them. I"m still half in and half out - there hasn't really been any run so far that's brought widespread severe into our area. So I think coverage will be an obvious issue for us.

06z NAM seems to have a bit of an issue with timing. Would love if it sped up just a bit.

Yeah 06z NAM nest has the parameters still but does the DC/Baltimore split it seems. Lame.

Comical...I picked a sounding in our area from the NAM nest at 22z on Thursday and it has a SARS match from DDC (95052300.DDC) with a 6in hail result. Still a TON of hail results showing up from SARS...interestingly enough - there have been some IAD ones showing up in the matches. FWIW (not much at this range) the sim reflectivity on the 3km NAM doesn't look all that impressive. I'm half in and half out.

I was pretty meh on it except for just keeping an eye on it up until today. Enough consistently good SARS returns and such to at least keep my eye on it. And having @high risk be interested is enough for me to stay partially in. If nothing else - the one big thing you always rightfully say is lacking (lapse rates) might be better this go around. I think the biggest "meh" right now is that it looks focused to our north. I'd feel pretty good if I was along a line running from like Pittsburgh to @mappy perhaps. Though I think the risk is there for some places to get a really nice cell or two. I think odds are pretty good of one of those days where one or two cells put down really large hail in isolated spots but the area at large doesn't see a widespread event. There are a few example of perhaps what could transpire in the Washington Weather Book IIRC - I loved that book in grade school.

@high risk I suspect if @Eskimo Joe pops in here he might be more enthusiastic than he normally would be. He's generally pretty down on lapse rates in our parts unless we get an EML or something to advect in. Obviously he might find a reason to deb...but he'll be an interesting "weather vane" - let's crack out the WW007 severe weather scale!

Posting the SREF at range below - not for the specific map type - but because it outlines the best risk area really well (and as such the area outlined in SLGT right now for D3).

I'll be honest - I'm not sure since SARS became publicly visible I've seen so many consistent model runs (even if it's the NAM out in time a bit) - return so many results. I'm used to it showing a bunch of "loose matches" but not many actual results in the boxes. There are a few soundings on the NAM in our area that have so many results they go out of the box for Thursday. Like @high risk has said - I think the main threat is north of the area. This might be a case where north of the Potomac stands the best changes. Will be interesting to watch model trends as we get closer and closer. Risk is there it seems for some big hailers (which except for isolated cases isn't super common around our area). I've seen a few soundings with interesting looking hodos too.

18z NAM nest has lost the earlier cells for Thursday and instead brings a squall line through parts of the area around 0z. Favors north parts of the area too.

CIPS at the 60hr mark on the 12z run has some robust events showing up in the analogs. 5/14/2010 - which appears to have been a big day for hail around the area. 6/24/1996 which had some local tornadoes among the other reports. 6/23/2015 - which had wind damage in the area.
