  1. Tabernacle, NJ - Rainfall Totals (Data from PWS Station KNJTABER5) 6-16-19 Sunday: 0.12" 6-17-19 Monday: 0.36" 6-18-19 Tuesday: 0.30" 6-19-19 Wednesday: 6.34" 6-20-19 Thursday: 1.88" 6-21-19 Friday: 0.05" Total: 9.05" Just a tad rainy...
  2. Downburst signature ... @SouthernNJ's favorite Mainly looks like sub-severe thunderstorms, though heavy rain/flooding is definitely a threat. Might be some pockets of gustier winds, too (like in areas with downbursts, like shown above)
  3. It'll be interesting to see how today plays out ... Compared to some of our other "severe" days this week, there are actually some pockets of drier air aloft, rather than the completely saturated atmosphere profiles we've typically been seeing. This should lead to some higher DCAPE values (up to, but generally below, 1,000 J/kg) which provides a somewhat better potential for gusty winds in some storms. 1,500 J/kg - 2,000 J/kg MLCAPE + 30-40 kt SFC-6km shear, along with some DCAPE, should be enough to fuel some strong/severe storms, though the tendency this week has been for storms to not be very strong despite CAPE/shear, but that might've been due to 1) water-loading of updrafts, and 2) too weak of a source of lift ... This tendency makes me wary to really be all-in for severe weather for today, but today's a new day with some more variables at play, and considering the standing puddles and saturated soil, I wonder if storms could produce enough wind to knock over trees in this environment.
  4. Wow... Pretty widespread flooding event occurring it seems. Woke up to another torrential downpour, with rainfall amounts approaching an inch since midnight. Meanwhile, areas to my west are getting a significant amount of rainfall.
  5. Rainfall finally ending now... Weather stations within a few miles from my area are reporting from 5.00" of rain, up to ~6.50" of rain.
  6. As the storms moved in, there were some breezy conditions in Tabernacle with wind gusts I'd estimate between 20-30... Not very windy, but I can confirm that the elevated velocities on radar did transfer (though there were not any damaging wind gusts IMBY) EDIT: Nearby sensors recording between 2" and 2.5" of rain within the past hour... Yard is back to being as flooded as it was back in the wintertime—beyond that by now. Pretty impressive train of storms.
  7. Heard a big bang of thunder a few minutes ago from this strong storm to my northwest... Looks like a bit of weak rotation in the storm, too.
  8. You're not wrong, I don't think! The storms in north/central Jersey have had some supercellular characteristics on radar.
  9. From Deptford, NJ... While fake photos and videos pop up on social media all of the time, this looks legit! Not much, but it does look like there's some circulation going on there... The couplet was pretty tight on radar for a time (though not very strong), and when considering the mesovortex formation, I wouldn't be surprised if there was some rotation and a tornado somewhere in there.
  10. It seems like you recorded some clouds moving up into the updraft...? It doesn't look like there was a tornado in your video, but there were strong winds in/around your area, which you captured a bit of!
  11. The bow echo moving across our area seems to have developed a mesovortex (which is the piece that you can see rotating in the storm, a bit south of Philadelphia) Mesovortices can produce tornadoes due to their rotation when there is sufficient shear + instability, which is why a tornado warning has been issued On the TPHL radar, you can see the potentially rotating couplet, which I circled here... It's pretty tight in this radar image, so even if there isn't necessarily a tornado, the possibility is legitimate!
  12. Here are some of the mammatus clouds blowing off of the storms' anvils... Taken in Tabernacle, NJ
  13. They're called horizontal convective rolls. I don't know too much about them, so hopefully someone else can chime in! https://en.m.wikipedia.org/wiki/Horizontal_convective_rolls There might be some helpful information in this Wikipedia article?
  14. Definitely some nice storms going on down there right now... Bowing segments in the line are a pretty classic signal for strong winds. The activity around this around is definitely less organized, with a mess of disorganized cells containing some downpours.
