it needs to develop into something first

If there were a record for the number of cloudy days during the summer with no rain we would break it easily this year...

Not from that latitude way out east. This recurving near or just west of Bermuda

Onshore barrage / heavy rain there. We had more like a California first week here dry / onshore.

Still a few around here. But far less Lots of acorns dropping though. Weird

Very upside down month, based on the average highs for the first 11 days of August. Charlotte is nearly 7F colder than Burlington, Vermont, and 6F colder than Buffalo.

For our friends in the Antilles, this is increasingly becoming a little close for comfort. Could be some indirect impacts there that become more direct if the south shift continues. To @40/70 Benchmark’s point earlier, that can muck things up if the ridge also ends up trending stronger or the big ULL in Canada is weaker in the long range. Still a lot to sort out here.

Tropical Storm Erin Discussion Number 5 NWS National Hurricane Center Miami FL AL052025 1100 AM AST Tue Aug 12 2025 Erin still has a well-defined low-level circulation, but the convective pattern has degraded since overnight, with only a band of moderate convection located within the southern part of the circulation. A 1226 UTC ASCAT-C pass showed a maximum wind barb of 36 kt north of the center, and the intensity is held at a possibly generous 40 kt. Most likely, this is a result of Erin's fast motion, which has been south of due west (265 deg) at about 20 kt. The guidance suite indicates that Erin may continue to lose some latitude during the next 24 to 36 hours due to strong low- to mid-level ridging over the eastern and central Atlantic, but overall the general motion should be westward through early Thursday. After that time, indications are that the ridge may weaken over the western and central Atlantic, causing Erin to turn west-northwestward, but there are model discrepancies on when that might happen and where the break in the ridge actually forms. The trend has been for a weaker Erin in the short term and possibly a stronger ridge, and a number of track models, including HAFS-A and -B, HWRF, the European, HCCA, and the Google Deep Mind, have shifted south and west for much of the 5-day forecast. The NHC forecast has shifted in that direction accordingly, and it should be noted that a significant number of deterministic models and ensemble members still lie even farther south. The environment of marginal water temperatures (26-27 deg Celsius) and low atmospheric instability and moisture appear to remain nearly constant for the next 24 hours or so. Therefore, little to no intensification is expected through early Wednesday. The environment and water temperatures become much more suitable for strengthening by 48 hours, and since the cyclone already has a well-defined structure, it could become a hurricane by late Thursday. Continued strengthening is forecast after that time, and the NHC forecast continues to show Erin becoming a major hurricane by day 5 (early Sunday). There is quite a lot of spread in the intensity models, and the NHC prediction is in the upper regime of the envelope, close to the SHIPS model, Florida State Superensemble, and ICON intensity consensus. KEY MESSAGES: 1. Although it is still too early to know exactly what impacts Erin might bring to the northern Leeward Islands, the Virgin Islands, and Puerto Rico, the risk has increased for Erin to move closer to these islands over the weekend. Interests there should monitor the progress of this storm. 2. There is even greater uncertainty in what impacts, if any, might occur in portions of the Greater Antilles, the Bahamas, the east coast of the United States, and Bermuda next week. As we approach the climatological peak of the hurricane season, this is an opportune time to ensure your preparedness plans are in place.

Truth! As I'm sure many feel similar/same, once we get to labor day, doesn't really matter how warm/muggy it is, as the signs/feels of fall are looming ever closer. Me thinks It's more of a mental victory in surviving summer.

Yeah, the record SST warmth near the Maritime Continent has been leading to significantly more -IODs over time than we used to get.

If you have the 6z EPS lat/long (TC position) @ hr 144, but 6z GEFS ULL intensity over eastern canada @ hr 144, that is a very interesting final solution...

Yep, and on August 12th it's more tolerable (to me at least) than a month earlier when it doesn't seem like there's an end in sight...

Half inch plus for you 6z models

Getting my well fracked on the 20th. Put a new pump in and expansion tank but recovery just isn't enough.

if erin doesn't recurve it changes the whole pattern. i could see it slipping south into the gulf

Morgantown did later go through its own heat island period for a time in the next decade, where it flipped the script and became a powerhouse of 90 degree days. In 1893, at the height of its ascent, it surpassed Pittsburgh by a whopping 35 days in that metric!

It's already fun to track the structure of Erin visually: looking to really shape up over the next day or two. https://weather.cod.edu/satrad/?parms=meso-meso1-02-96-1-100-1&checked=map&colorbar=undefined

I don't want to even know what Crabtree mall looked like yesterday. So far, this is turning into one of those old time 90's Augusts with constant rain and clouds. I used to hate those as a kid as it really killed our pool season. Now I don't mind so much.

On the topic of 90 degree days, that 19th century Pittsburgh heat island must have been insane. Why so many more than Morgantown? Wow! According to this, from 1880-1882, Pittsburgh had 105 days at or above 90F, while Morgantown had either 8 or 4, with only a handful of missing days?

It was pretty much wall to wall heat and ridging from June 21st through July 31st. We got a relaxation of this pattern for the first week of August. This current heat wave is a weaker reflection of what we got back in June and July. So the shift in the modeling for next week is the hurricane lowering heights in the East as it recurves west of Bermuda. Would like to see some improvement in the rainfall situation. Since we have seen time and time again how heat has remerged in September into October during dry patterns. We would at least need to keep the tropics active in Atlantic to have a shot at avoiding potential fall record heat when the pattern has been so dry.

Some isolated thunderstorms are possible today! Barring a surprise, 90 looks likely today, and low 90s look increasingly likely for both days this weekend. Friday and Monday, it looks unlikely, but close enough that a small change in the forecast could allow us to reach 90F on one of those days. With the current forecast, we could be up to 18 days of 90+ by Sunday. Can we reach 20? Believe it or not, the last time there were two consecutive years with 20 or more days of 90+ in Pittsburgh was 1933 & 1934 (when observations were downtown). There were 21 days in both 1933 & 1934, so it barely accomplished that feat. 1987 & 1988 was very close. Of course, 1988 had tons of 90F heat, with 1987 finishing with 19 days.

Yep, they've been quite loud the past week or so. Definitely giving those hot day vibes. On another bug observation note....we still have deer flies buzzing around these parts. Granted not as many as June and early July, but usually they are completely gone by late July. So running a couple weeks overtime at this point.

That's a lot ot get rid of lol

Yes I am.. looking at trends.. to the west is looking better just have to get rid of that crap to the NE

Yeah, that to me is the takeaway, back n forth w/ humidity is ok to many, as humidity is expected in the dog days...
