Heaviest rain I ever experienced. It actually hurt to be out in it even in proper gear

Water was coming in through our doorknobs. I had never seen that before.

Didn't realize we had a confirmed EFO in southern Lancaster County during last Thursday's storms.

Wow, I had no idea either

After a nice cool start to September, looks like we get to normal in a couple days and then above normal for a while.

Below normal rainfall.

48 when I left the house. Crisp.

43 degrees this morning. Appears the hummingbirds are gone for the year.

Widespread low temperatures again in the 40’s across much of the county. The lowest was our normal cold spot at Warwick Township at 42.7 degrees . If you think we have been experiencing a chilly stretch you are correct. Yesterday here in East Nantmeal was our 20th below normal temperature day over the last 22 days. We continue this below normal trend for the next couple of days before we may see near to slightly above normal temperatures by this weekend before slipping back to a little below normal by next week. No rain at all in the forecast for the next week.

Went on XMAXIS2 site to multi station option, made it all of pa with options for site type, climate division, lat/long, county all checked. Then did preceiptitation and ran one for actual amount, another for departure from normal. The period of time was the default option I believe. I downloaded 2 csv files and ran it through a Google colab workspace with python. One of the things chat gpt and Gemini can be decent at is setting up python scripts for simple data manipulation.

I've been working on analyzing the entire co-op and station weather data for all of Pennsylvania from 1900 onward for preceiptitation, temperature, snowfall if available and using it to learn a lot more about data cleanup, validation, and analysis while slowly working on using Python for more complex gis and graphics. But like most things in the end it's a whole bunch of statistics and models built on same math. AI has been a godsend for the programming and self learning there.

Officially came in as 3rd driest August on record for the Commonwealth. Ohio, Kentucky and Vermont all had their driest Augusts of record.

Average monthly lows for July and August for CXY were 69.7 and 61.4; MDT's were 71.5 and 63.  Disparity even greater thus far in the early part of September, with CXY at 55.1 and MDT at 57.9.
