Yesterday's high temperature at East Nantmeal tied the Chester County record set 116 years ago for the chilliest high temperature for the date. That record of 52 degrees was set at both Coatesville and Phoenixville way back in 1909. Here in East Nantmeal we have received 1.33" of rain over the past 2 days we are now 0.31" above normal for rainfall here in 2025. We start to dry out today with only a small chance of some showers. We look to stay well below normal through Sunday before we moderate to about 5 degrees below normal by Memorial Day. Temperatures look likely to remain below normal for the next week. Our next shower chances arrive later on Tuesday.

A beautiful Memorial Day weekend underway across the area although at least 10 degrees below our normal highs for the day. Still relatively chilly tomorrow but temperatures do rise to within 5 degrees of normal by Monday with highs near 70 degrees. Rain chances increase again by Tuesday night and Wednesday and we will again turn well below normal temperature wise. Shower chances continue for much of the rest of the week with temperatures still a few degrees below normal for the end of May.

Radar is a popcorn explosion again as the atmosphere is so cold for the season

60F and mostly cloudy, windy

 

Forecast for tomorrow- increasing clouds...

 

Had a couple of brief showers here, looks like another about to roll in. It goes from sunny and beautiful out to dark clouds and breezy with a shower, then back to sunny.

The scattered pop-ups mostly missed me yesterday (although my Delco sister got nailed by one but then got a cool double-rainbow at the end that she texted a pic of).  But for the previous 3 days (5/21 - 23), I ended up with 1.20", which takes me to 5.82" for the month so far (vs 2.76" for April).

Got up to 64 yesterday and bottomed out at 50 this morning. Currently a mostly sunny 51 and so far not as breezy as yesterday, with a dp of 45.

Less than a month and we start losing daylight again. Summer is flying by!

67F

About 2-3 weeks from now, we'll have the earliest sunrise, and we stay constant daylight for about a few weeks before starting the downward trajectory in late June. As we roll further into July, it becomes more noticeable.

I attended the Iron Pigs game last night.  Cold unstable air mass showers popping up throughout the game.  Observed three rainbows  with one of them being a double rainbow. However, if you look directly over the US foods advertising board, in these photos in right field, there appears to be a cold air funnel forming with the cold unstable air mass in place. I would like Mike and his team to look at these photos for verification. It did not appear to be a simple rain shaft but actually appeared to have rotation and looked like a funnel. If this was indeed a cold air funnel, this would be extreme for our area  but I would not doubt its formation with this very  cold unstable air mass above in late May.

It is possible to be a cold air funnel, but it is tough to tell the details from these photos (plus no video to see any motion). It could also be an enhanced area along the leading edge of the rain curtain associated with the shower.

I think we lose 2 seconds of daylight the first day after the solstice. For me, it’s the first sign of autumn  :weenie:

(Followed by Lowe’s and Home Depot putting out Christmas decorations on July 5th.)

Today will feature our 9th consecutive cooler than normal day. Clouds will be on the increase as our next rain event approaches late tonight and lasts through the day tomorrow. Tomorrow will also be an unseasonably chilly day with highs again remaining in the 50's with the exception of near 60 in some lower elevation spots. We could see another 0.5" to 1.0" of rain as we continue to now move into a surplus position regarding rainfall. Thursday through Saturday while not a wash out by any means could still have some showers before we dry out by Saturday PM into Sunday.

Squeezed out one 24 hour period without precipitation

Radar looks great for rain coming in ahead of schedule, possibly overnight? This last month was like February 2014 in May.

 

 

Yeah, getting some light rain here, for about the last 30 minutes.

I was at that game, too. I saw the rainbows, but missed the funnel.
