Ahoff Posted June 5, 2023 Share Posted June 5, 2023 Maybe we should start this thread since we've already seen our first 90 degree day. Link to comment Share on other sites More sharing options...
Ahoff Posted June 5, 2023 Author Share Posted June 5, 2023 Currently tied for 42nd longest stretch with no measurable precip at 15 days. After today we make it to a tie for 30th longest dry stretch. If we get past Tuesday without rain we have a chance at making the top 10 longest dry streaks. And the first time recording 20+ days with no rain since 1997.

TheClimateChanger Posted June 5, 2023 Share Posted June 5, 2023 The dewpoints of 30F at 4 am and 31F at 10 PM appear to have tied the lowest values on record for those hours at Pittsburgh International. Models suggest plenty of dewpoints in the 30s, and possibly 20s later in the week, so we could approach the record lowest dewpoint of 24F set at midnight on June 3, 1986. With the exception of a few hourly records tied last year, all other record low dewpoints were set on June 2-3, 1986, and June 11, 1972. Like this year, both 1986 and 1972 featured developing El Ninos, and both went on to be rather significant events (peak ONI of 2.1 during the 1972-1973 El Nino, and a peak ONI of 1.7 during the 1986-1988 El Nino). This suggests there may be a link between El Nino events and dryness in early June around this region. 1972 did turn much wetter, with the remnants of Hurricane Agnes producing record flooding in Pennsylvania. That appears to be a bit of an outlier though, especially since El Ninos tend to reduce tropical activity in the Atlantic basin due to increased wind shear, so I certainly wouldn't bank on a repeat of that. While the low was 51 at PIT this morning, outlying areas were considerably colder. Some morning lows around the region include 39F at Zelienople, 40F at Youngstown, 41F at Franklin, 41F at Butler, 42F at New Castle, 43F at Latrobe, 44F at Washington, and 45F at Indiana and DuBois.

Looks like it, yes. The high and low that day were 68 and 34, respectively. On June 2, 1986, it was 66/47, and on June 3, 1986, it was 72/41. So clearly, relative humidity levels are considerable lower with this current spell. Link to comment Share on other sites More sharing options...
donyewest Posted June 5, 2023 Share Posted June 5, 2023 8 hours ago, TheClimateChanger said: Atlantic basin due to increased wind shear I've been watching discussions around this and there appears to be a lot of apprehension on the hurricane outlook because of how anomalously high the Atlantic SSTs presently are. I tried to find studies on the balance point between Atlantic SSTs versus Nino intensity and there aren't many, prob because aren't many samples, ha. Heck, this blurb shows an 1899 analog which did have an active hurricane season. ECMWF pure model-based forecast just came out aggressively for an above-average season. Thing is, Nino shear is not as intense in the Gulf and mid-latitudes, and if there is a dip in Nino intensity or a block then the window may open for a hurricane to rapidly intensify. A hurricane, whether slowed/widened from shear or super cat 5, would ride up whatever high pressure region *cough*Bermuda/Azores*cough* available and that could open us up to a threat.

Ahoff Posted June 6, 2023 Author Share Posted June 6, 2023 Looks like that damn smoke will be keeping us cooler than expected this week. Was pretty thick for a time yesterday and looks to start pretty thick today. Link to comment Share on other sites More sharing options...
Ahoff Posted June 6, 2023 Author Share Posted June 6, 2023 Seems kind of odd that Canada has so many fires, yet I've heard nothing about any western US fires. Is that weird, or am I just disconnected? I really don't remember being this affected (smoke-wise) by Canadian wildfires. Link to comment Share on other sites More sharing options...

Was pretty thick for a time yesterday and looks to start pretty thick today. Smoke is pretty intense for sure. Made for a really bright orange view of the sun. Almost looks like it's foggy out, but its smoke. Trying to get over a respiratory cold and I can definitely feel it making it harder to breath. Normally I don't notice anything different during these air quality alerts, so must be the combination of the two. Link to comment Share on other sites More sharing options...
Ahoff Posted June 7, 2023 Author Share Posted June 7, 2023 Currently, tied for 26th longest dry streak at 17 days. After today we hit 18 and move to a tie for 21st. If we make it through Saturday, like expected we should move to 21 days and tied for 9th longest ever and top ten most dry days in a row. Link to comment Share on other sites More sharing options...

Pretty close to the record hourly minimum dewpoint at KPIT right now. Link to comment Share on other sites More sharing options...
north pgh Posted June 7, 2023 Share Posted June 7, 2023 I like the weather for temperature but I miss the thunderstorms and we need humidity for that. Still a lot of summer to go. Link to comment Share on other sites More sharing options...
jwilson Posted June 7, 2023 Share Posted June 7, 2023 Friday could be another bad smoke day. Courtesy FireSmoke.ca - this is Friday morning say between 8 AM and Noon. We'll see if it holds. Link to comment Share on other sites More sharing options...

Still a lot of summer to go. Definitely an unusual start to met summer. This dry back door cold front pattern would be more useful with a strong STJ in the winter.

We'll see, I'm seeing only 20% this morning. Almost no rain has been able to materialize on these chances. Either way, this was a remarkable dry streak.

TimB Posted June 10, 2023 Share Posted June 10, 2023 Should add one more day to the dry streak at PIT to make this the 10th time we’ve gone 21 days without rain. All of the others occurred at least partially in meteorological autumn. Link to comment Share on other sites More sharing options...
