It probably had some effect but I don't think it was the driver. I'm no expert but from what I've read on many dx sites large stable airmasses like we've had the last few days are really engines when you have heat inverting from the lakes. I could be full of )(*^ , but that's my interpretation.
I really wish Mr. Hepburn would grace us with his wisdom because his maps, as I've said many times, are right more than wrong, which is why I have such respect for meteorologists.
I read a book a few years ago called "The Signal and the Noise: Why So Many Predictions Fail--but Some Don't " and there was a chapter on weather prognosticators and how much more accurate it is today in comparison to even a decade ago. Use of super computers to crunch weather data has made normal weather, hurricanes and other extreme weather events more predictable and it keeps getting better.
Take the last Hurricane, they said Irma would turn North and slow down 4 days before it did exactly that, the fact they got the eyewall track wrong by a piddling 30-40 miles is what deniers of science will cling to while those of us with open minds marvel at the fact they called it way early on a 185 mile wide storm.
I know this is seriously off topic but it's relevent given our increasing success at tropo capturing . Mr. Hepburn and Jon Harder offer proven scientific tools to help us grab those far flungs, just as the NOAA/NHC provide communities with life saving warnings.
The one thing I love about our group of tropo hunters is we collaborate and share real time info, much like weather stations, sure, there are bragging rights with some captures but I've never seen anyone hold back info that could help the group.
Like all things in life we benefit when we cooperate and band together.
P.S. Getting some major tropo out of Youngstown, WKBN, WYTV and WFMJ are solid, zero Pittsburgh's but Cleveland is also booming.
P.P.S. The other morning I awoke to WNEO's "Classic Arts Showcase", it was around 6-7am and they had some dude, I don't think it was Zamfir because his hair was jet black, wailing away on the pan flute......what demographic of early risers demand PAN FLUTE music????
These are the sort of questions that kept George Carlin and me awake late at night!
