Also, here is Harrisburg. Just a short drive from Chester County. Weird that Chester would have such a wildly differing trend than Philadelphia or Harrisburg.

Oh yes and as @chubbspoints out, you are still changing the mix of stations over time. It is possible that the individual stations can all have a positive trend [like that for Phoenixville] while the average tally for the basket of stations shows a decline due to you varying what stations are included in the basket over time.

Well you know I'm going to have to comment. (1) Data from 1920s - 1960s is likely not directly comparable to more recent data at some of the sites. May co-op stations reset their thermometers at 5 or 6 pm, and thus would register extra 90s on hot days [when the following day may or may not have reached 90]. Would expect this to add at least a couple or few extra 90-degree days on average each year. (2) The trend is minimal from the low elevation sites, and biased due to weighting 2020s equally even though only 4 years are included. It looks like the 2020s have had an unusually low number of 90+ days, but it's based on only 4 years of data. Same thing with the high elevation sites, but you also then extrapolate the trend back to the 1890s even though the data stops in the 1950s. In fact, the trends from 1950s to the present are about the same and we can be pretty confident that general pattern would have persisted into the 1890s. So the big drop off implied in the regression is clearly not accurate. If the remainder of the 2020s have a high number of 90+ readings, the trends could be significantly different. (3) These trends do not agree with Philadelphia data [from a county neighboring Chester County]. These data were collected by trained meteorologists from the Weather Bureau and later National Weather Service, and thus are less likely to contain errors and are unaffected by any changes in observation time. I can anticipate you will claim the UHI effect is the culprit, but there's no explanation for why center city Philadelphia would have fewer 90-degree days than Chester County, which would have been very rural, in the 19th century and early 20th century.

This area needs to be watched very closely as it moves into Westerville and New Albany.

You are beating a dead horse

No post from Wiz about tomorrow's severe threat? Nice EML in place!

lol

Clearly two tornadoes confirmed by radar here

got 1.08" here. had four rounds of storms, the last one being severe. really cool to have a situation where the atmosphere just wanted to keep convecting

Nobody in SNE is sniffing 80F next week.

Not going to rule anything out, but it looks like that storm moving into Cincinnati seems to be getting cut off by outflow. There may be some spin-up potential around Lebanon, OH as well. There's also the storm moving towards the northern Columbus suburbs. Places like Plain City and Dublin will soon be in its path, and perhaps Westerville and New Albany down the line. On the other hand, SPC Mesoanalysis is showing a sudden drop-off in tornado ingredients around the Columbus metro, but I wouldn't count on the storm weakening before it impacts the Columbus metro, either. This storm is well-isolated from other storms, so there is definitely potential for concern. EDIT: rotation tightening between Mechanicsburg and Plain City.

yeah, what looked like a cool shot only ended up being slightly below avg this weekend. Even with NW flow and an E trough in the extended all we can manage is slightly below average 850 temps on a few days

DCA: 101 IAD: 102 BWI: 101 RIC: 101

Good bet with the overnight lows. As the city and immediate surrounding area continues to build more and more big skyscrapers, the heat Island at night will probably get even warmer.

The cell approaching the northern burbs of Cincinnati could be trouble.

I always said how similar they can be. The budding trees have some amazing shades

Some nice structure on the tail end charlie dell in central Indiana just south of Indy about and hour and a half ago.

I really think they need an office for the northern plains, central plains, Midwest, and Dixie. All have those areas have their nuances with tornado forecasting

The first true sunny day with hills of neon light green canopy, it does rival fall foliage. Just vibrant shades of fresh green.

It is underrated for sure. It seems like every year I forget how many shades of green there can be until spring rolls around.

85?? You should call NBC 10 and let this boob know he's way off!

Yeah I’d say that sounds about right for 1500ft. Last piles of snow just melted from those elevations not long ago. Not going to go from patchy snow to leaves in two weeks time. Down here in the valley we get the warm afternoons to heat the soil.

Congo line of big tornadoes coming
