Severe threat later today looks real. Watch that dying MCS in WPA for possible regeneration downstream in EPA later this afternoon into the evening hours. Once the T-storms are through tonight we'll see torrid conditions for Wed-Thurs, then moree MCS potential for this weekend in association w/ the next heat burst.

NittanyLion
This afternoon/evening is looking pretty good for you guys down there, regeneration off of the dying MCS or maybe some re-initiation even later this evening, as the best indicies look to pass after 00z.

Surface CAPE projected to be around 1200 with Lifted Indicies around -5. Showalters around -3, K-Index of 37. More impressively SWEAT indicies above 400 and total totals near 50. Bulk Richardson number projected near 20, and EHI above 1.5.

Now this is all based off of last nights NAM run, but these indicies would support a moderate outbreak of thunderstorms, possibly severe at times. A super cell or two may also be possible with the BRN and EHI's where they are, and Helicity values around 300. Main threat would likely be damaging winds as is usually the case with any MCS, but also 850-500 Lapse rates are above 6. And with any supercells the outside chance of a tornado.

Nothing too impressive out there right now, but we'll see what kind of heating you get down there.
NittanyLion
I am more impressed with the POSSIBILITY of Thursday morning. Any threat on Wednesday seems to have disappeared.

Now there is not much dynamical support for Thursday's event, which obviously is a huge downside. However with some of the indicies where they are, it definitely bears watching.

CAPE is projected to be nearing 3000, with lifted Indicies as low as -9. Showalters are as low as -6 and a K-Index of 40. 437 on the SWEAT Index, and total totals of 53. Numbers like this can lead to major outbreaks.

Sometimes with this much instability, just enough shear, and moisture like that, any little dynamical support you can get can set something off (and there may be a prefrontal trough near the area). Time of this appears to be 12z-18z right now.

Thursday evening brings another chance of some storms with the frontal passage.
satellite_eyes
Nitt when you talk about 0z, 12z, etc is that actual time? I always wonder about that esp when i read forecast discussions. Should we adjust the time? So 0z is really 8 pm for us (minus 4 now but minus 5 during Non-DST). I know on the models that's how it is but was wondering about forecast discussions when they are not talking about models also.

Yup its Greenwich Mean Time (or Zulu, hence the z), so 12z is 8AM and 18z is 2PM.

Thanks. Meant to say Non-DST but you knew what i meant. I changed it.

HRRR supports rapid development behind the initial weakening batch of rain, but keeps most thunderstorms south of NYC.
Moves into the area ~4-5PM.

Best shear and instability lies from I-78 southward right now.

Millersville WRF starting to pick up on Thursday's possible event. However, keys in on southern New England instead, where there is more dynamical support, like most cases this year.


Unfortunately NCEP ran the hurricane models instead of the NMM.

I'm basically convinced that somewhere in the Northeast will have a big severe weather day on Thursday...
Stormchaser
Mike, the WRF has a couple rounds of convection, some T-storms this evening and possibly a more organized MCS late tonight. I think we're still very much in the game for strong storms tonight.

That was just issued here for that line, though this area is in the northernmost part of it. We have more of an east wind component now and temp has fallen off to 82.3 here as a result so the dynamics may ease and weaken those storms a lot. DP here is 65.

The last cell in the line, which is very healthy looking, looks like our only hope here. The frontend of the line separated and crawled north and south of us as if it was trying to avoid a virus. It's very still and warm and humid here. 78.8 degrees. The brief maritime flow has died and there's no hint of it at all in the air.

Just ended here in Queens. Pouring rain for a good 40 minutes with a few intermittent breaks, temp has cooled a little but it is still very muggy.


This is a warmfront. Humidity is going the other way. No rain here. It looks like Monmouth is the only place that didn't get any rain.

Here's a link to some pictures of the severe weather out in south central PA today. There are a lot of good funnel cloud / tornado pictures.

Well for about 4 minutes it came down in wind driven sheets, total was only .13. Sure was hoping for more, maybe tomorrow.

Tomorrow has almost no chance and 95+ is on tap, Thursday too. Thursday could be the severe day. Regardless near or over 90 thru Sunday in Monmouth is likely. One last shower has sprung up in minutes with a hvy core near Matawan and is moving east. Missing me north by 4 miles. Frustrating.

I just received some rain and a few rumbles of thunder. Nothing exciting.
