The current temperature of 83 at PIT is tied for second warmest March day on record, and is the earliest in the season that we’ve ever reached 83.

Great day SW of NYC-horrid here with clouds and mist 51

Thanks, Anthony. I hope they really timber! But the “timber” of the AO and NAO are still just to neutral. They were timbering to actual negatives starting around now that were shown 8 days ago per the images below vs today’s bringing them down to just neutral and not til early April: big diff.

You will have plenty of warm days ahead. Its not the end of the world

Cloudy, windy and cool along Barnegat Bay, NJ this morning...

Love is in the air.

That is correct. I never it is wasn't a record breaking air mass. Local contamination from infrastructure is common even in sparely populated areas. Parking lots, vehicle traffic, solar panel arrays, AC units, etc. all contribute. And the digital thermometers have a warm bias compared to glass thermometers b/c they record instantaneous temp and react quickly to any changes in the air. ASOS use 5-min avg temp to mitigate this, but sensors and equipment out there are far from standardized, never mind not all ideally located (look the areal view of the official temp sensor in Death Valley, parking lots and solar arrays all around). So it's not just UHI that skew temp records. It's all too easy to get caught up in it all when big wx events occur. I get that. It is our passion for wx that drives it. However, we should not let that cloud our judgement when talking about caveats and shortcomings that just happen to "deflate" that excitement or how impressive it is. Taking everything as face value and acting there is nothing to question or analyze is not a good scientific position.

67 and sunny

Horrific day. 49 and socked in here. Upper 60s in NJ. Kill me

They’re shattering records in areas of sparse population. It’s simply a record breaking airmass.

UHI does impact daytime highs (Baltimore/Inner Harbor is perhaps the most egregious example). Also, local airport infrastructure and sensor placement impact highs, regardless of UHI.

84.6° feels legitimately summerlike in the sun

Train gets back to Harrisburg at 8:45 or so. Should be just in time for some good lighting and wind.

I never said the primary urban heat island effect was not at night. 1-2 F per day biased warmed max is huge for long-term climate records. esp. when you consider we think we can get avg regional or global temps correct/accurate down the the 100th of degree, and we obsess when we "beat" a record by a fraction of degree, not mentioning the uncertainty at all. Using precision to give an illusion of accuracy. Bad science. And some sites have a huge warm bias during the day. Look at Baltimore/Inner Harbor (KDMH). You often see it 7 F warmer for maxes than BWI, and this is an official climate location and gets reported as fact.

Where has @Itstrainingtimebeen . It's been well over twenty four hours since he's made a post.

60 here

He's not a practicing meteorologist. He works for an organization that largely rejects AGW. Regardless of his position and employer, he should post accurate data. It's difficult to know why he would post information regarding Phoenix that is so obviously wrong (112° in March, 100° on March 3, and 7 100° days in March during 1879), especially as Phoenix is a high-profile city and, by its nature, has resources that can be found through research.

Absolute values given taken snapshot are not the same as longer-term values. In the end, it's what occurs over a long period of time and how it all averages out, rather than individual events. And what you chose as a period of time matters. We tend to think in very short time periods, contaminated by recency bias and the lack of full knowledge of wx history. And the concept of "wins the debate" is a flawed premise. What matters in science are facts and the truth. It does not care about who "wins" or "loses."

I was just looking at some of the meso scale parameters, myself, I was quite surprised to find thermo dynamic fields were still quite meager to non existent, at this hour, however some instability and a few other meso scale enhancements appear to be advecting into our area from the west as I write this . Kinematic fields are definitely starting to show some enhanced parameters.

Apparently we're getting a quarter to an inch of rain tonight. Models all over the place

First 80+ of the year here, all the way up to 82ºF currently on a stiff SW breeze. I already like the severe potential today more than the setup last Monday. We don’t have anywhere near the shear/helicity parameters so tornado threat will be more minimalized. Wind and hail will be the primary threats with this. Regarding CTP disco’s previous concerns about cloud cover, SW and SC PA I-80 and south are fully in the sun and mixed out with the warm, gusty SW winds. So I think we’re going to build some half decent CAPE as the afternoon wears on and also advect in somewhat more moist air. Low and mid-level lapses are very high as well, as noted on the SPC disco. This is the kind of setup that can yield a surprisingly strong line of storms with strong downbursts. Low Level Lapse Rate: Mid-Level Lapse Rate:

I just realized Chris Martz is a meteorologist, which you must know. I had assumed he wasn’t. Now I’m more surprised he made those errors about 1879! A pro met doing that? Shouldn’t he have known better? He’s not an AGW denier, however, per the following link. Instead he seems to be in the category of non-alarmist AGW believer. His beef doesn’t seem to be with AGW, itself, but instead it seems to be with AGW alarmists. @donsutherland1is my assessment correct in your opinion? Quoted from link below: do you think he’s being sincere here? Is it possible he’s possibly making a fact based case? The magnitude of warming and the rate at which it occurs make all the difference in whether global warming is cause for alarm that requires economic decarbonization and/or large-scale interventions like SRM, or is largely unimportant in terms of environment and public health. Just how much warming will occur is dependent on “equilibrium climate sensitivity” (ECS), which is the amount of warming that results from doubling atmospheric CO2 levels plus any feedbacks that amplify or dampen the slight increase in temperature caused directly by CO2 and other greenhouse gases (GHGs). • If ECS is ≥3°C, then the climate system is highly sensitive to GHGs, and climate warming is therefore a concern. • If ECS is <3°C, then the climate system is largely insensitive to GHGs, and warming impacts are exaggerated. This seems to be the likely case given that we have not seen increases in most types of extreme events, climate models overestimate warming (U.S. DOE CWG, 2025)[30] and the state of human welfare has never been better than it is today by nearly every measurable metric. https://oversight.house.gov/wp-content/uploads/2025/09/Martz-Written-Testimony.pdf
