Can't beat that! Enjoy! Now if only we could keep this rolling through December...

Today will be the 16th below normal day in a row at PIT. By the time this streak ends, it should be the longest streak of below normal since 21 days at this same time of year in 2017.

I'm curious why we seem to hit our peak heat in June and then have "cold" shots in August.  Shouldn't that be reversed?  Is that just recency bias?

Kind of an interesting dynamic.  This is looking forward to winter, but that dominant -PDO is something to note from this summer, how it may affect our winter.

I can't remember, is that good or bad for winter?

Generally worse for snow in the East.  The overall regime from the last decade+ was a -PDO-led pacific, which has resulted in a sort of snow dearth, particularly along the East Coast.

Granted, we don't rely on quite the same mechanisms here in the mountains, but decreasing snow chances can impact us just the same.  Especially true if you're hunting for a big one.
