Click on the station detail and they all upload at these same times.

I can't wait to read this reply...

Local met questioning the official temp…

Ive got this timing down to eliminate any questions about lagging temps... PWS update ever 5 minutes at 4's and 9's... 4, 9, 14, 19, 24, 29 ect... KBUF updates at 54 minutes of every hour. Both PWS and KBUF will update ever hour together at the 54 minute mark. Set your site map over KBUF at 958 hit refresh and you will have a grab of all current temps within 5 minutes of each other, before the next update at 959. For this screen grab I took it at 958pm. KBUF temp and all surrounding PWS temps were updated at 954pm.

Great minds think alike! Posted that $#!& at the SAME TIME! lol

I don't know... it just never looks right... Here is the 10 pm live reporting (KBUF updated 4 minutes prior to this grab at 958, all stations reported temps at 954pm ). It's just not right that KBUF is running almost 5 degrees above every other location surrounding it. You can question the recreational PWS data but look at how consistent the sites are across central Erie County. The KBUF number is just such an outlier it should be tossed from the data set, not made the official #. Even caught one of the local Spectrum News mets questioning the temp at KBUF on air tonight. We have believers!

Interesting... Area Forecast Discussion National Weather Service Buffalo NY 1015 PM EDT Mon Sep 27 2021 Wednesday night into Thursday, H85 temps lower to a chilly 0-1c in wake of the front into Wednesday night. Weak cyclonic low-level flow and additional synoptic low-level moisture along with sufficient over-water instability (delta t/s over 15c) with north-northeast flow across Lake Ontario resulted in increasing pops some for lake effect on Wednesday night Genesee Valley to Finger Lakes. At the least, will see a lot of lake effect clouds south and southeast of Lake Ontario. So, despite the colder temps aloft, think min temps on Wednesday night will not be as low as they could be due to some clouds and fresh northerly winds behind the front. Min temps in the 40s will be common, but interior valleys of Southern Tier and higher terrain east of Lake Ontario could briefly dip into the upper 30s. Thursday will be cooler with highs ranging from the 50s to around 60. Temps on the lake plains may sneak into the lower 60s briefly on Thursday afternoon.

Kinda? This was the reply I received. How do you make it out? Like yes, the overnight temps are warmer because of UHI effects... but it is what it is? It's just always the warm spot... always... temps were all taken between 854-906 tonight. 1.3 degrees warmer then next warmest station... Next 10 closest stations were within 2.5 degrees of each other... KBUF is again an outlier... Can question the accuracy of the PWS but its hard to when they are so consistently close in range with their numbers.

Best thing I have done for my mental health is getting off FB. Been using it less and less this year and recently just deactivated my account and deleted the app. Politics, Drama, Scams, just so much "noise"... it's really just a wasteland for your mind to become lost. I do like using Twitter now. You can really narrow down your feed to more custom results of your interests. You can search real time happening events a lot easier as well. Just has better functionality in my opinion. Also if you don't use your real info , you can be a ghost, feels good to disappear in a way.

Skinny but nice looking band off Lake Erie this morning.

Soon!!! 2 WRFs and the HRRR precip output for LER band tonight. I think it stays north of the metro most of the night.

Lake Erie is starting to bubble a little bit. See if anything gets organized overnight.

Lake Erie starting to fire up! I’m thinking we see a nice single band consolidate after dark.

6AM top of the hour temps at the sites around KBUF this morning... Even on a cloudy rainy night the station is reporting 2-3 degrees above the nearby average.

SUMMARY...Severe threat is advancing downstream across western PA into extreme western NY. Primary threat for damaging winds, along with a tornado to two, will be over the next 1-2 hours.

Wait and see what rolls in… Cloud flows down on the lake earlier were nice. Rain cells were forming just out past the break wall with rain shafts dropping down.

Dry slot is bringing clearing skies so SPC pops a twister watch! Clear blue and sun to my south right now. Surprise twist tonight over WNY?

We are back online! Heard it may go in and out for next couple days as they finish upgrades but dome is back on.

Temp is a function of location. So is that fancy talk for saying that the sensor could be impacted by urban heat retention at night, but it is what it is?

This is the 3am update. KBUF reading was from 254am and PWS were from 259am. 10 unique different PWS all reporting within 1.0 degrees of each other... Then KBUF actually jumping up to 69 degrees at the update, sitting almost 2.5 degrees warmer then the next warmest station.

No. It shows they read my message but nothing. Be nice to at least get a we'll look into it or something. Feel free to send those docs to them too, maybe if they see it being reported by multiple people they will at least address it or explain why it looks the way it does? I know we talk about the "Island" impact but do we need to look at this on a larger scale? Construction everywhere right now, vacant unused old store plaza lay waste, green space is disappearing. Rapid new builds expanding out past the suburbs. It's just mind boggling thinking how much heat gets held in all that pavement, that will ultimately later in the evening result in increasingly warmer overnight periods. Hear that mentioned a lot lately about how warm it stays after sunset, this could be a very could reason why. I look at a place like Cheektowaga where the airport is (delta posted a pic on prev page) Its densely populated residential, heavy commercial with massive lots, and a massive amount of rail lines. The only green space in town is the super fund toxic cleanup zone by the airport. Crap buried there probably exhausting some heat as it breaks down.

That’s why I looked at 8 stations all within 3 miles of the airport. 1 or 2 could be skewed but all of them?

Alright did one last run of the numbers by hour and I think this helps see what we are talking about... Can you guys let me know if I am explaining this right and it makes sense as to what I am seeing? Ran the hourly temps for the 9 stations from 4pm on 9/19 thru 9am on 9/20. Used the top of the hour readings at each station, the same time KBUF posts so time is consistent within 5 minutes. Weather during this period was uneventful, only some high fair weather clouds just before sunset and just after sunrise. There was a variable wind out of the east at 5-8mph, so Lake Erie influence would be rather muted if any at all. Overnight was clear so this should give a good picture of the full impact on solar heating impacts, loss of heating overnight and general UHI impacts that we could be looking at. To try and summarize the readings I averaged the hourly temperatures at the 8 surrounding PWS sites and used that as my "base line normal/average". I then lined that base line up against the temperature that KBUF reported for that hour and used the difference as a "departure from normal" value. ...(((THIS MAKES SENSE RIGHT?)))... *NOTE* KBUF temperature is rounded while PWS sites are down to tenths so even if I put my margin of error right around 1.0 degrees, the data will still stand out... From 4pm-6pm KBUF is running right in line with the surrounding stations, and is actually cooler than some nearby. Just prior to sunset at 7pm we see the surrounding stations all make pretty large drops (roughly 4 degrees) but KBUF only drops by 2 degrees. The decrease continues to a lesser extent throughout the overnight and by 5am KBUF is running over 4 degrees above the average of the nearby stations. As the sun rises after 7am the large variance rapidly goes away as the other stations start to catch back up to KBUF by 9am with the help of the warming sun. If this doesn't support the UHI impact at KBUF overnight I don't know what does! Thoughts?

That dang hole of despair again… better get use to it boys… gonna be a longggg winta!

I'm going to send this afternoon. Now that I have all the PWS data downloaded into a workbook Im having some fun cutting the data different ways. One last thing I wanted to look at was to dig into the hourly data a little more for the morning time and see when KBUF isn't making the same dip as the other stations. Here I ran the HIGH temp vs LOW temp. KBUF is right in the middle when it comes to the high temp aspect, so not a sensor issue. The disparity it temps is just coming during the overnight / early morning low hours. Just a side note I would probably pull the Willi79 station data from the set as it likely has a bad sensor or placement as it is showing as the warmest daytime station and the coldest nighttime station which is a bit unlikely.
