1st month to end up drier than normal since January

That is interesting.   Those cool streaks don't seem as common lately, so that's pretty cool.  I believe August ended cooler than normal too, due to the cool conditions.

Seems like Summer was just given the bum's rush recently

both the gfs and euro ensembles have a high in the low 60s for next Friday here in mt pleasant. Should feel great after a couple days of 80s

Almost time to open up a September 2025 thread very soon.....

Only hit 71 today. The record low maximum temperature is 67 back in 1930.

Still, mid-to-late August is just way too early for back-to-back days of overcast skies, for sure.

nelson is like one of the most chill people here.

so, to say he’s annoying is super lol. definitely a projection there.

Nelson can't be a chill person here if he wanted to rustle frostfern's jimmies.

66 at noon.  Friday will feel warm when it’s back in the mid to upper 80s. 

Garbage for sure

89’d today, maybe the last wave of 70 dews for the year.

Same here. Looks like the 90s are done early for the year. 

The bad news: Very short-lived garbage pattern ahead for the next few days. Although a bit early for this, but back-to-back days of expected suicide weather starting tomorrow.

The good news: Nice pleasant weather takes over just before this weekend begins with temps rebounding back to the lower 80's for Friday into Saturday. 

Temps really cool down big time early next week. Highs are forecast to be in the low 70s, though there are areas that could be stuck in the 60s or even upper 50s!

Overall, we're reaching what it appears to be the final nail in the coffin on this summer.

Summer is over

This weekend/early next week might actually bring you some organized widespread convection for a change.

TWC/Wunderground's going hog crazy with at least an inch of rain for tomorrow night into Sunday. Barely any of the models are even near that much.

We got a good region wide soaker over here this evening after some downpours late this morning/early afternoon too. 

1.21" here. First day with any rainfall for this month.

89'd yesterday, 89'd again today. Big fail these past few days.

Looks like a little early-fall-like storm brewing on Thursday to end the month. TWC has us in the mid-70s for the high.

12z GFS barely lets us even reach 70.

Canadian has us in the mid-70s.

i'd say it has been pretty active.

A good part of the year so far, even though we're going to have to pay for the string of wet months at some point in the future. Just as expected, the 6th consecutive wet month. Currently at 29.08" for 2025, just less than 20" needed to at least tie the 10th wettest year on record (48.99" in 2018).

Stuck at 80 with all the debris clouds, even with the Heat Advisory in effect today. No way we're going to top 90 or even the upper 80s. NWS might as well just cancel the Heat Advisory today.

Dropped to 78. Heat Advisory not cancelled yet, but now extended through tomorrow. Heat Advisory still in effect today is just too much hype.

A thing of beauty

6-10 day:

Not for long, according to the 8-14 day:

The upcoming "cool" stretch next week may have to come with a price. NWS ILN is talking about a potential cutoff low for early next week.
 

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Broad h5 ridge over srn U.S. weakens over Ohio Valley as a
stationary front in the lower GTLks begins to move swd into CWA Tues
night/early Wed. The boundary stalls in srn/south of CWA early
Thurs, with h5 s/w energy topping it late Wed/early Thu. Storms will
be likely over the region with these forcing mechanisms found in a
very receptive, moist airmass. they should be most active from Wed
afternoon through Thurs afternoon and die out in the evening. There
are indications that it could be south of the CWA earlier in the day
with little activity in the south ending closer towards noon.

High pressure to the north and upper level ridging will keep a dry
ne wind over the CWA through at least Sat. The center of the high
and axis of the upper ridge will pass east through the CWA overnight
Sat. Behind them, winds turn e and then se on Sun. GFS has an upper
level cutoff low undercutting the exiting ridge, bringing precip to
sw CWA Sun. European does not have cutoff upper low and brings a
zonal wly flow behind the departing ridge, keeping any rain threat
south of CWA.

The end of hot and muggy looks to begin on Wed with some moderating
temperatures, fall to below normal Thursday, and remain below normal
through the end of the forecast. Highs Thu-Sun will be in the mid
70s nw to near/low 80s se. Lows for this time frame will be in the
low-mid 60s. One exception is a cooler Fri night with mid 50s
along/n of I-70 corridor, near 60 along Ohio River.

If you're looking for a good dry stretch, it's safe to say that it's just not our year.

I am f’n done with summer. I’ve had enough.  

Hell, we might as well be done with 2025. Too much rain this year.

Ended up hitting 90 for the 3rd day in a row this week. First heatwave since right after the 4th of July weekend.

With the prolonged stretch happening right now, if only this was Winter and the map were to be a snowfall map.....

In between the "relentless rains," Dayton has done quite well with heat. Today was the 11th 90F+ reading of the season. Dating back to 1955 (71 years), that amount has only been exceeded through today's date (July 12) in 5 years (1966, 1988, 1994, 2012, and 2020).

Through yesterday, the mean temperature was 6th highest in the threaded record. A little weird that they use the warmer, low elevation Miami Conservancy District building records for 1943 & 1944, instead of the higher elevation airport site.

At the airport site, it has been the warmest since 1935, outpacing both of those years. Today's heat should help these numbers somewhat. The forecast calls for generally warm and summery weather conditions over the next several days, with highs forecast in the upper 80s tomorrow & Monday, near 90 on Tuesday and Wednesday, upper 80s Thursday, and perhaps cooling to the middle 80s by Friday.

Yesterday marked the beginning of an upcoming stretch of relentless rains. The next 1-2 weeks are looking to be a wash. Shades of July '92.

Today's 12z Euro run doesn't show any dry days at all until July 26th. 

Beyond the 10-day, TWC/WUnderground has rain and storms all the way through at least the 28th of this month. Brutal.


NWS doesn't have any dry days in sight through next weekend.
 

If we're going to have such a long stretch of wet weather through a good portion of the 2nd half of July, we might as well just get a cutoff low, an Omega Block or some other blocking pattern.

Through tonight
