0.40" Fairly short downpours . BTW... ran AC first time this year, with DP of 75.

nice little cold front passage tonight, beautiful outside with the breeze

Turning up the heat it appears

There is a murder in Boston right now. Up 29 with 4 mins left in the 2nd. Can't happen to better people like Irvin and Kidd.

Speaking of our lord and savior, we've seen relaitvely a benign Stein on social media for the past few weeks, or even months. And should the dry heatwave commence, I bet he perks up

I'm not sure I ever saw pollen plumes like today. The increasing southerly winds really had it looking like blowing snow out of the forests, except the color was light green. There was a pollen wind-lip on the edge of the hood of my SUV today, blowing and drifting . Whiteface Mountain shared some photos on the official ski area account about the pollen the past couple days. Montpelier today. Wind stripping the trees.

You’re late. Tip already issued one of his patented Sonoran heat release warnings.

Let Wiz work it?

When I left my office in Waterbury around 2:30, there was so much pollen blowing off the trees it looked like a Haboob. A pollen haboob.

As expected latest GEFS now washout any trough in the E completely and may even be hotter than the EPS now.

GEFS has been running too cold for a while now. It will correct warmer with time.

Going to be a windy Friday.

Yes…got exactly what we were hoping for today

There's a lot of hand wringing going on in the media about the Livonia tornado being "unwarned" since it was only a SVR with a TOR possible tag, some media people are saying tor possible warnings should just be tornado warnings. What's you all's thoughts?

More nothing today.

I agree. But one thought I always come back to is that it is really difficult to get real, prolonged winter weather around here. As someone who grew up in the largely snowless winters of the late 70’s and 80’s(save for a few storms)I am reminded of an explanation I heard from a meteorologist regarding cold and snow around here. Plainly put, it’s really difficult due to the maritime influence on our weather. I’m sure there are technical reasons which I do not know about or understand, but that’s it in a nutshell. Lots of factors have to fall into place. But we seem to have gotten away from the mindset after the very snowy early 2000’s. Seems to me that we had an incredible streak that was just not sustainable from a climate perspective. My .02 I know now is not the time to be discussing winter, but the mindset is the important thing to remember here. We have to be realistic in our expectations

Hopefully some good storms accompany it

0.14" in camp hill. Tropical like Sent from my SM-G970U using Tapatalk

Seems to be even more difficult today, despite all the technology.

Let's start this baby off for those of you interested in actual factual climate for our area!! Thanks again!!! Below is a chart splitting the Chester County PA Climate Period between almost down the middle since 1895. We have 64 years climate averages by month from 1895 thru 1959 with a comparison to the most recent average temperatures for the 63 year period from 1960 thru 2023. The top (Grey) includes all 27 Chester County stations (even those introduced with modest relative elevation increases). The next section (Yellow) shows the adjusted NOAA/NCEI Altered Adjusted Data. The bottom (green) only includes the 17 stations at a similar relatively lower elevation. Not surprising across all of the actual data there has been essentially no change in our average annual temperatures over the last 63 years vs. the prior 64 years. The only way we get any warming (+1.2 degrees) at all to appear is to apply the post observation adjustments to the data (as shown in the altered data in yellow). Of most interest overall Januaries have trended colder and Decembers warmer but all other months only show slight variations over the split climate periods of record.

I thought I would start a unique thread specific to the Philadelphia Mount Holly Zone for those of you that have any interest in this kind of long term climate data. That said I wanted to respect those of you who wish to avoid this kind of long term climate analysis which due to our limited years of data will often lead to debate you may wish to avoid! If this kind of longer term Climate Data Analytics is not your cup of tea...please avoid this thread as many on both sides of the debate view this topic sort of like a religion! But if you like so many folks on this forum seem to enjoy and learn from this kind of real world climate data and analytics please feel free to post here. But please if you post here....be sure to come forward with your data to support your position as folks on this thread are more interested in facts over what you feel the climate might be perceived to be doing here in the Philadelphia / Mount Holly Zone !! Thanks to all of you!!!

Let’s get the heat in here asap
