Central PA Summer 2025


Recommended Posts

The warm and muggies continues for the foreseeable future. Today should be the warmest day over the next week with lower elevations getting close to 90 degrees. A heat watch and a flood watch have been issued. Rain chances increases again toward evening with the NWS forecasting between 0.75" to 1.25". Tomorrow might be relatively the driest day with Thursday looking like the wettest after this evening. Temperature wise it looks near normal with highs in the mid-80's but with nights a few degrees above normal in the upper 60's.

I wish I could give a Tamaqua weather report, but my station took a crap. The main unit fried when I had to shut power down briefly. I could get a new main unit, but I've been intrigued by the Tempest weather stations, so leaning toward just getting a new set-up.

I didn't have to lean too much. Station already ordered.

Let us know how good it works. I read when it rains it's not accurate. Also Ambient came out with one similar to The one your getting.

I will.

I've had two stations with wind cups, and I could almost never get a reading above 20 mph, no matter how windy it was. I've had the house shake, check the reading and...15.9 mph. Doesn't seem right. The readings themselves were questionable. I had many, MANY, 13.6, 15.9, and 17.2 readings. Like it had pre-programmed increments.

We'll see how the rain sensor works, but I've had a few times where the tipper in my station would get stuck in the tipped position and then stop measuring.

It'll be interesting to see if the sensors in this one do better.

I thought it would be of interest to do some deep analysis into my own weather station data that has been operational in East Nantmeal since November 2003 vs. The only NOAA Climate Reference Network (CRN) station here in Chester County which is the PA Avondale 2N station. These CRN stations are a highly specialized weather station designed to provide long-term, high-quality measurements of climate variables like temperature and precipitation. In essence, CRN stations serve as a high-precision benchmark for monitoring the nation's climate, ensuring the availability of reliable data for understanding and addressing climate change. I ran an analysis of East Nantmeal vs. Avondale 2N over the last 18 years that we have both been recording the weather. I have to say I am pretty pleased to see that our observations could not get much closer than this – exactly the same average temperature over 18 years of data!! I have only used a Davis Vantage Pro 2 station with the fan aspirated shield over the entire 22 years I have been recording data.

Can you do an overlay of these two stations, plus your full Chester County dataset over the same timeframe (2007-present)?

For sure it should show the same relative warming curve that has been occurring during these years....

Well, can we see it? This would be a good test of the validity of the official ChescoWx temperature index over the past couple of decades. We'd have a USCRN station, your own gold standard East Nantmeal data, and then the official ChescoWx county-wide average for 2007-2024.

Same relative minor warming curve as expected! image.thumb.png.d5564c967ca2ab9a14288820814ce515.png

Thank you! I wouldn't say that's an insignificant difference, no? The two highest quality stations (Avondale and East Nantmeal) with data available over the entire period show a warming trend of 12.64F/century and 11.14F/century respectively over that time frame, while the others show a warming trend of 6.91F/century. That's nearly half as much warming.

Chester County is very fortunate to have a USCRN station. With the official ChescoWx (TM) index deviating so much from the CRN data [especially when it's largely corroborated by your own temperature data] just over the past 18 years, isn't that a concern?

Nope! It simply says that statistically Avondale and East Nantmeal are the same during the years in question....they are if anything tightening the statistical differences as we move through the last 18 now going on 19 years! Maybe the other stations could be as advanced and precise as the 2 what you call "highest quality stations"

Flash flood warnings up here. That was 1.75” rain in 45 mins or whatever.

Up to 0.62" in 15 minutes so far.

As I watched it out the window up here in Harrisburg, I thought the visibilities were similar to a heavy snowfall. Knew those rates had to be something special. Seems that’s confirmed.
