E PA/NJ/DE Summer 2025 Obs/Discussion

[LVLion77]

Got a quick 1/3” at home from that batch, but my actual location during the storm near Costo Allentown must have been at least an inch. It was a torrential downpour and heavy storm.

Enhanced risk of severe thunderstorms today I guess it’s possible for a tornado watch today starting around 1-2 pm.  Looks like we have a difluent split in the flow which also probably means isolated to scattered strong activity rather than a squall line.

That is rare being in "Enhanced". 

I hit a high of 91 about 10 minutes ago with a dp of 79.  I have now been transported to the swamps of Louisiana!  Had bottomed out at 71 and it was already 85 by 9 am.  Currently 88 with dp 78 at post time.

First 90F day of the year and it's torturous.  After a week of 60F days.  Thunderstorms are required after this.

I hate the heat coming up, but it has been so cool I can’t complain much. Severe Thunderstorm Watch is up.

[Hurricane Agnes]

And away we go!
