Jns2183 Posted yesterday at 12:38 PM Share Posted yesterday at 12:38 PM I thought people might enjoy these bar charts and heat maps I made regarding preceiptitation for Pennsylvania. The PA climate division map is included for reference Sent from my SM-G970U1 using Tapatalk 2 4 Link to comment Share on other sites More sharing options...
Jns2183 Posted yesterday at 12:43 PM Share Posted yesterday at 12:43 PM It's all based off of coop and other data and is a quick summary so it's going to be highly dependent on how many reports are in region and how many of those are "winners" vs "losers" in the summer storm lottery. It's quick and dirty and I did not clean the data so I'm sure errors abound Sent from my SM-G970U1 using Tapatalk 2 Link to comment Share on other sites More sharing options...

Itstrainingtime Posted yesterday at 01:24 PM Share Posted yesterday at 01:24 PM Friday is quietly trending incrementally warmer...new forecast high this morning for Lanco is 88. Regardless, that kind of warmth will be a memory once again by Sunday. Link to comment Share on other sites More sharing options...

What is the source for the last 30 days? I just took a look at precipitation data from all CoCoRAHS, Coops, and WBAN sites, and I think August will be among the Top 5 driest for Pennsylvania. It looks like it was either the driest or 2nd driest for the State of Ohio. The official NCEI values are scheduled for release next Tuesday, I believe. Average of 269 well-separated stations with no missing data is 1.94 inches. Average of 417 stations with not more than 5 missing days is 1.90 inches. This actually gives a pretty good estimate of what the official tally will be, so it looks like the statewide average will come in under 2" for the month, although gridding could make it close. There are only 4 Augusts with a statewide mean under 2" (1930, 1957, 1995, and 1951). Link to comment Share on other sites More sharing options...

Thought it early, but maples show first signs of fall usually in early september around home.....and its early september. I'm currently in Clearfield. Definitely color up here. I was expecting that here, but Huntingdon is basically Kentucky climate-wise so seeing any color in late August was a bit of a shock. Cats are getting bulky already. They did that last year around this time and at least around here, the winter was kinda rough from December until February. Stayed cold until Spring but didn't get much snow. Seeing a lot of folks saying the winter is going to be backloaded this year and the clipper should return. I may be back up this way in a month or so just in time to deal with it. 3 Link to comment Share on other sites More sharing options...

mitchnick Posted yesterday at 08:19 PM Share Posted yesterday at 08:19 PM Must be time for a Fall thread. JB's preliminary winter forecast. I'd be happy with it. Sorta lines up with the Cansips, at least temp-wise, and somewhat the Euro seasonal. 2 Link to comment Share on other sites More sharing options...

ChescoWx Posted 8 hours ago Share Posted 8 hours ago We should see our 1st above normal temperature day in 17 days today for many areas. A couple of cold fronts the first weak this evening and the next one on Saturday is stronger. Each of these may bring some much-needed rain. In fact, the National Weather Service has much of Chester County with between 0.75" to 1.00" of much needed rain by Sunday morning. Behind that front we turn much chillier again by Sunday night with a return to below normal temperatures with lows in the 40's and highs in the low 70's next week.

There are only 4 Augusts with a statewide mean under 2" (1930, 1957, 1995, and 1951).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.

Jns2183 Posted 1 hour ago Share Posted 1 hour ago .12” rain - really hope that line out west makes it but I have doubts. Good stuff to my E 0.01" here. 1.37" since July 21st. The forecast for the next 10 days isn't promising. Fully expect to be pushing 60 days with less than 1.50". I suspect we may have a historically short fall foliage this year. For some reason my mind is linking late summer early fall droughts to increase in the probability of October hurricanes hitting the east coast. No idea why though.
