May end up with a non-diurnal temp thing going on here.  Temp has slowly crept up and hit a high of 59 just before 4 pm when the sun stayed out for a more extended period of time. But then with a warm front approaching, the temps are supposed to remain in the mid-upper 50s in the urban areas overnight.

Currently partly sunny with lots of high clouds and 59 with dp 48.

SPC SWDY2 has the CWA in the marginal risk.  Will see if that changes depending on temps tomorrow, which include some possible RERs -

I finally "bottomed out" at 53 just before 4 am before the temps started heading off to the races.   Took a bit for the overcast to break up with the lifting of the warm front, but it finally did.

Currently partly cloudy and 70 with dp 64, having shot up almost 20 degrees from yesterday's dp that was in the low-mid 40s.

A line of storms moving S--->N w/warnings popping up...

Yeah, I read the warning for northern Delaware, and southwest Delco is included, although my point and click doesn't have a warning (yet).

Just finished mowing the back, just in time it looks like (plus it's dark now, lol).

Eta, got the warning.

Been seeing a fair amount of lightning off to the south and southwest. Winds starting to pick up. Getting pretty stormy. Interesting way to start off this event!

Hearing a boatload of walnuts falling, I suspect by Wednesday they'll be just about all down. Bumper crop this year, and taking their time dropping.

Depends on which way they face.  :lol:

I know the back of my house faces NE and I am guaranteed a good outside "window washing" from any nor'easter that comes my way.

This year I was hoping the first thing to hit those old storm windows was flakes !   Latest I recall taking the big ac out in a while.  I’m older now so only clean them once per year.  Fall works best so can open the blinds, let the sun hit that thermostat and save me some oil.  Summer it’s dark in here to keep the heat out.   It literally is the complete opposite of what we did growing up!

just a small boomer went thru
