Where do you get these totals from?

I live in West Grove and got a total of 1.11" per my Ambient Weather station. 

2 miles from my spot where I picked up 0.73" they received over 2" ....tropical showers and t-storms vary across short distances

[Hurricane Agnes]

Wasn't sure if I'd get there but I did tap 90 today just after 2:30 pm.  That was day 4 in a row for a current heatwave and have now had 6 of 9 days in July of 90 and above.  For the past 3 months (MJJ) so far, I have had 13 days of 90+ & 1 day of 100.

It's currently a partly sunny and hazy 88 with dp 72.

[Hurricane Agnes]

Wash. Rinse. Repeat.

This.  But even with some with fairly steady rainfall, like with stratiform events, the rainfall totals can vary over short distances.  I use all my local Davis stations on Weatherlink, and more often than not, the totals are at least a bit different.  And the stations are all within a few miles of each other.

.30" total for the super wet week and two flood watches. Flood watch three in progress.

 

Third time is the charm, right?  Three flood watches can't equal less than .5"??

I'll bet a lot of Davis users don't bother to calibrate the rain guage.

Maybe not?  Point remains, though.  

[KamuSnow]

Getting into some pretty heavy rain here. Very dark, radar looks good, a little thunder and lightning, no wind to speak of. Lots of rain, a quarter inch in the last 5 minutes.

Eta - make that 1/2" in 8 minutes!

Let's make that 3/4" in 10 minutes, lol. Getting windy now too!

Now 1" in 12 minutes!

Even across the street at times. It is a fascinating time of the year. The difference between the winners and losers is a lot greater than the other seasons .

Yeah, now in a flash flood warning AND a severe thunderstorm warning. Almost 1.5" in 20 minutes. It's the real deal.

Yes!  I'm jealous as hell.  Just don't get flooded... Or struck.

Thanks, we're sitting on the porch, watching the rain. 2.25" so far. Looks like it wants to expand across the river, maybe you'll "get some"?

Good stuff!  It does look like it's intensifying into Jersey.  Regardless, the whole line is looking pretty damn good.  I want mayhem, but I'm okay with beneficial rainfall, too.  Lol

[Hurricane Agnes]

It got pitch black here and rain is starting, coming up from the SW.  Temp is 83 with dp 74 and getting thunder and some lightning.

Hope you get dumped on, but 2 hours max. Is that reasonable?

[LVblizzard]

Worst possible timing for this line of storms. Union vs. NY Red Bulls was supposed to start at 7 and they delayed kickoff 10 minutes before. Now it’s uncertain if they’ll even play the game tonight. Glad I didn’t buy tickets.

Umm... Yep.  We're good.  

[Hurricane Agnes]

This is a noisier storm than yesterday (although yesterday had the winds).  Rain rates have been somewhat modest - ~1/3"/hr so far.  Have 0.08" in the bucket at post time.  Temp knocked down to 77 with dp 75.

I am too. Up north, I'm way on the outside looking in.

Yeah, my son is town there. Luckily his buddy has season tickets and they offered admission to The Commodore Club, so they are dry. Just praying for a safe ride home. Gonna be lots of flooding tonight!

[RedSky]

Thundershower in Montgomeryville with good cloud to cloud lightning

[KamuSnow]

Rates have gotten lighter, but just crossed the 3" mark. 1st gully washer in a while here. Also cooled it down to 73°F.

[Kevin Reilly]

Moderate rain lightning thunder no wind 70f humidity 97% dewpoint 69f

 

Total Rainfall so far: 2.40" all falling since 7:15 pm.

We have flood watch verification in the south spots woohoo

[BBasile]

Still looking decent on radar and dronedar.   Keep it coming! 

[Kevin Reilly]

Looks like a new area focusing right along the Delaware River down to Delaware Bay.  Looks like a mesoscale low just west of Dover Delaware moving NE.

That’s twice now in the past two days lower bucks get hit. Straight up 95 to Trenton
