E PA/NJ/DE Spring 2025 Obs/Discussion

[ChescoWx]

Quite a difference in rain totals since last night. Ranging from as much as 1.10" across NW Chester County like here in East Nantmeal to as little as 0.02" down in West Grove and West Bradford. If you missed on rain so far chances will increase again for most of the area as we move through the rest of today.

[Hurricane Agnes]

I am surprised I didn't get any more overnight so did finish up with 0.67" from that round.  It has started raining here again as another round comes in.

Bottomed out at 63 just after midnight and it's currently raining (0.06" in the bucket at post time) and 67, with dp 65.

Showers and thunderstorms today before tapering off this evening. Some spots could see between another 0.50" to 1.00" of rain. Much cooler today with temperatures remaining in the low to mid 60s. Showers and cooler temperatures will continue through early Tuesday before we dry out on Wednesday. Rain chances increase again by the end of the new work week.

[Hurricane Agnes]

And unexpectedly, the sun has popped out.  Ended up with 0.11" from that isolated shower.  Will have to see if it becomes "self-destruct" and the sky clouds up again.

Currently partly sunny with the temp quickly rising and at 68, with dp 67.

I already had two Sun showers. It's muggy out, uncomfortable.. 68f/dp 65 f

A little late but below is the April Climate Summary for Chester County. April finished 1.9 degrees above our normal average temperature which is our 27th warmest April since records began in 1893. The top 10 warmest are avg temp (year)

57.3 (1921) / 57.2 (2017)/ 56.7 (1941) / 56.5 (1915) / 55.8 (2019) / 55.7 (1945) / 55.5 (1942) / 55.5 (1910) / 55.4 (1960) and 55.4 (2023)

Up to .75” so far. Only 9.25” to go for the Euro to verify.

Stating the obvious, this is much welcomed. I kicked up so much dust mowing yesterday you’d think it was August.

[Albedoman]

No way does even 2 in even verify today. Absolutely no training of t storms. Air is too stable and too dry. Just enough rain to keep the pollen down today.  I only had a .40  inch of rain yesterday- very localized.  2 day total --.70 inch of rain. Still no drought buster rains for sure but it does help the garden.

Yeah, radar is/was a disappointment today. Total flop...

68F/DP 65F  

[LVLion77]

Yep, today thus far has been a total flop - 0.03” since midnight with drizzle currently and a nowcast radar that shows much of the same the rest of the day. Again the best action is to the west… several hundred miles west. Perhaps tomorrow will be our day?

[MGorse]

A whopping 0.03 inches of rain so far. 

[JTA66]

384 hour GFS has snow from the finger lakes extending down into northern PA. Ralph told us to be patient.

[RedSky]

2.20" 

Today's rain has missed to the east

 

[RedSky]

GFS highs in the 40's next Friday 

[Hurricane Agnes]

Well another little scattered shower earlier this afternoon added 0.11" to the bucket for a total of 0.22" for the day so far and a 2-day event total of 0.89".

The high so far today was 71 just before 11 am but that has dropped down since.

It's currently overcast and muggy with temp 67 and dp 65.

And to your northwest. I've got 1.95" in the gauge since midnight up here in Tamaqua.

Southern Chester incredibly still dry on radar history

Truth! 1.26" in NW Chesco vs 0.22" down in West Grove....

[JTA66]

Anyone know anything about birds? I have a robin building her nest on top of my hose reel which is directly under my dryer vent. I don’t mind the nest and plan on leaving her be. But I wonder if the hot exhaust from the dryer will be harmful the eggs (which she hasn’t laid yet).

[LVLion77]

Surprised to see the sun this evening. 0.08” during the day from sprinkles and light showers. Precip forecasts for tomorrow and Tuesday are significantly reduced now. I wonder if the accuracy of forecasts will increase with advanced AI.

I agree. From 2-4 inches to less than an inch for the LV and points north. I received a whopping .02 more rain than you today.  Hell, the new small leaves on the trees kept the street dry. There were more pollen sacs in the street from last nights gusty winds and brief heavy shower that I thought the township could bring out the plow.  Training of t storms is not in the cards anytime soon.

Just an observation. Each time the precip forecast missed badly this spring, like today, we had an easterly wind here in the LV. I am no meteorologist and I could be very wrong, but this time of the year that east wind equals a cool stable flow off the Atlantic. Perhaps that is the factor that blows up a number of these forecast? Upstate NY seems to have gotten our forecasted heavy rains today. We are forecasted to have east winds Monday as well.
