My eyes opened up a bit when I checked the llvl moisture. Don't often see dews into the 60's in this type of setup.

Perhaps, but it looks like it cools back down again after day 10. -

Those don't sound like representative readings. Likely in a sheltered valley or "frost hollow" that would violate WMO siting guidelines. -
Yep. Worth keeping an eye on is all.

Take a wild, cracy, absolute out-of-left-field guess about what his response may entail...go ahead-go nuts.... -
Just looked at the 6z GFS...figured you would have certainly said something. Big change from yesterday with that Sunday shortwave. You have adequate shear with steep mid-level lapse rates driven by a strong cold pool with sfc dews in the 60's. Good recipe for hailers and strong downbursts.

my major question is why the world doesn't just slightly adjust back from those events like the 15-16 super nino? is it just "unable" to?
-
We may not hit 70 today. Cloudy, drizzly 66 at the moment

Great. I can't wait to see daily pics of Powderfreaks friggin snowstick.

Was quite foggy this morning, Starting to take down the garden, Game Cams are out, Going to be in the woods in a couple weeks, From what i can see, Not as many acorns dropping this year like last year.
-
Yeah. The dewpoints usually aren’t real high and the longer nights allow it to start cooling down fairly early even if it does get really warm during the afternoon.

Standard deviation is just the average distance of each value in a dataset from the dataset’s mean. In a normal (or near normal) distribution (tied to the central limit theorem), then 1, 2, and 3 standard deviations from the mean cover ~68/95/99.7% of the data. So by nature >= 2-3 standard deviations away from the mean implies >=5% chance of occurrence. And IQR is just the middle 50% of the ordered data. Replacing a dataset’s tails with anomalies will skew the mean and increase the standard deviation, but not affect the IQR (or even median). There’s nuances to all of this, but that’s the gist of it.

As long as it's not an all day rain event like this past Sunday. Garage sale rained out. Would like to try again this Sunday.

Where do you see low 80s -
36° with fog this morning, 34° without fog yesterday.

Inverse to the warming summer effect, the airport location move has had a cooling effect in the winter, especially on mins. I'll do a more detailed post at some point about this.

BUST!

Yeah, you can see that a bit on this CoCoRaHS total map for our general area. My house is near the 13.74" in Silver Spring. Totals from June 1st - now. A big chunk - maybe 4" - all fell in a couple hours that one day in July when Sligo Creek flooded.

Im looking at the end of the month into the first of October for a big cold blast. The teleconnections look to be in the right spot for possibly something big. PNA will go very positive around and after the 15th. The NAO and AO will be negative..I know it early season but the PV will continue to be in a weakened state. Also yes we will warm up a bit but I don't see any record heat in sight.

So let me understand the logic here: the move of about 15 mi primarily east to an entirely new location for the airport records is not important and totally comparable to historical records, but the the new ASOS environment in the same general location as the old airport is not comparable? As someone who lives here, let me explain why you're wrong. In the summer, most late mornings/early afternoons see clouds/storms build up over the mountains and then drift east over the plains. Locations that are further west get the cloud cover sooner, and therefore tend to have a bit less sunshine warming in the afternoon. When the clouds produce cooling rains, that also reaches western areas sooner. This is the primary reason that moving the airport significantly east of its previous location has resulted in a bit higher afternoon temps at DIA, compared to the old Stapleton airport. It's also the main reason why, if you look at Boulder's long term records, the average summer highs are about 2 degrees cooler than Denver's. The Boulder airport is at almost the exact same elevation as Denver, but is located about 15 mi closer to the mountains. Mean temps are one thing, but there's no doubt that the location change has had a small, 1-2 degree (I'm happy to provide the data) warming effect on the airport's highs, which then results in more 90+ days. We have a ton of days here that top out in the 88-92 range, so you can see how the numbers would get bumped. No one said this makes the warming summers since the 1990s an "artifact" of the airport move. In fact, I did say we have warmed and see more 90+ days regardless.
