I wonder if the NWS office in Peachtree City can handle all these flash flood warnings across most of Georgia right now since the CWA covers almost all counties in Georgia.
My local NWS office is KGSP to their north, and the WWA texts from there appear here too. I haven't paid close attention but it seems to me they do well keeping up with things in the northern parts of their CWA. Their messages are clearer and laid out better; many of mine have locations halfway down and others near the top. Peachtree is more consistent. They're up to speed on convective events but I haven't followed hydro events with them. I'm soon to be moving further south so I'll be watching them more closely as I'll then be within 50 mi (maybe less) of their CWA then.

We didn't have anything locally except some minor street flooding in the usual places, but KGSP blasted several FF warnings out which seemed uncalled for IMHO. The potential was there but no rivers or streams seem to have overtopped their banks or even came close. I think the mou8ntains had some of that. KGSP ain't what it used to be for accuracy and they "cry wolf" over anything at the drop of a hat so lots of local folks don't pay them any mind anymore (Plainfield syndrome). To their credit they are getting better deciding when to forecast against the CAM's predictions lately which has increased their accuracy. Upstate SC is sometimes very hard to forecast for, and this areas best forecasters have always had long experience here. KGSP lost that through transfers and retirements.

Hello fellow Utahn! Yeah, I've heard the same questions about the location of the temperature recordings being moved at SLC, not sure as to how much it's impacted the numbers either, but I can say having lived my whole life here (49 y/o) the summers are noticeably hotter, even than 10-20 years ago, the last several have been particularly bad... I'll be curious what you find.

I just did a little looking through ASOS readings from Hill AFB and SLC Airport and there's not some obvious smoking gun (not that I expected one). I chose Hill AFB as a comparison because it is the closest station with a long temperature record.

There's a good bit more warming at SLC airport than there has been at Hill AFB, though the majority of the difference is in the nighttime readings. Much of that can be attributed to urban sprawl/urban heat island effect I would assume. Based on google earth historical images, I *think* the SLC ASOS was moved to its current location in 2010. Much of the nighttime difference has been observed since 2010, so perhaps that new location is partially causing that. It also appears that the area around the ASOS site was filled in with gravel in 2017. For reference, from 2001-2010, SLC airport nighttime lows increased by an average of +0.94°F, while Hill AFB increased +1.142°F. However when you look at 2011-Current, SLC airport has increased by +2.94°F, and Hill AFB has increased by +0.43°F.

Here's some of the data in charts. I'd like to spend a little more time digging through some of this data when I get some free time. That's tough to come by these days with two little ones.

Notes on the data: All data are 10 year averages of July/August temperatures. Using yearly data makes it too noisy to present, so I used 10 year averages.

Also after looking through the temp records summer temps are indeed up pretty much across the board for Utah over the last couple decades. I'm not sure if the 100°F days are inflated a small amount lately due to the airport readings, but I suspect even if so that this was the hottest summer on record here. Today was easily the hottest September day on record.

Perhaps in time I'll adjust to the lower humidity and the summer will feel hotter here, but based on this summer I'll take 100 with a dewpoint in the 35-45 range over upper 80s and a dewpoint in the mid 70s every day of the week.

I agree, most of the time, but right now we could use some humidity here in Oregon, just not the "scuba suit in a sauna" type. I've been here eight years and haven't seen this level of concern (though I've heard about it occurring in California). Here's the current red flag warning.

Here at the edge of the Coastal Range, our state forest areas are closed, but at least for now, we're not in the high-risk zone. They are across the valley, though, on the Cascades side, and of course up north in the Gorge. Not sure what's happening in eastern areas.

So, starting overnight in some areas, I think, tens of thousands of Oregonians will have power blackouts, in 90 to almost 100° weather, strong winds with gusts in the mid-40s, at least in the Gorge area, and because winds are from the east, lots of smoke even if nothing ignites here -- through Saturday. Best case scenario.

Very cool data - thank you for sharing! Yeah, I've noticed over 30 years or so of following that SLC's temps don't drop at night like they do north/south 30 miles or so (Ogden/Provo)... I wonder too how much a shrinking Great Salt Lake impacts our warming temps and our lackluster snow numbers in most recent winters? Nice that our temps have returned to about normal as this is usually a really nice time of year weather-wise in Utah...

I obviously don't know that much about the weather in general out here yet, I've only lived here a few months so I'm not sure how much the changing water levels in the lake might affect those things. It'll be interesting to see how the next few winters are here. There's been a noticable decline in snow over the last decade, but to levels only slightly lower than those during the last low "snow cycle" here in the 30's/40's. Looking at the historical data, here's the amount of snow per season vs. the amount of precip that fell. This number decreasing lately does indicate that with the warmer temps, more is falling as rain as opposed to snow. It'll be interesting to see if this trend continues or not.

Just have to vent this.

<rant>I think the hype about fire conditions in Oregon this weekend was scary and overdone. The red-flag warning is certainly necessary, there are a few more fires today, and the northeast and southern parts of the state are definitely in bad shape, with evacuations underway, but what I'm seeing here is nowhere near 2020 levels of nightmare, no matter what the Salem paper reports.

It's just fire season, on a windy day. This is not to diminish what Oregonians are going through, but it's no different from the experiences others are having, without gloomy coverage, in Idaho, Montana, New Mexico and other western states.

This article from Montana, a few days ago, is a good example of the coverage I like because it informs but doesn't panic the public.

And no rolling power blackouts there, either, AFAIK.

When it comes to fire coverage in Oregon, I'll glance at it but will get my serious information for making decisions from sites like Inciweb from now on. Some journalistic choices here seem to be based more on panic buttons than common sense in a truly dangerous situation (as fire season always is, everywhere).</rant>
