One of the bigger model busts not involving an MCS that I can remember around here. Sold band of 1/2-1" QPF progged, maybe 3 drops fell from the sky. Partial sunshine now.

A big bust for sure. I was expecting a downpour this morning and I was pleasantly surprised that I didn't need to bring an umbrella to work today. However, Friday's heavy rainfall was a surprise, so I guess it balances itself out somewhat.

Well that came out of nowhere. That would be #70 this year if all the prelim stuff holds up.

lol, remember how many times we got screwed in June and July? Mother nature still owes us a truckload of precip. But I'll allow payment to be deferred until December and January. :whistle:

what's the average date of the first frost? ( for whoever wants to answer, i know the central/west subforum covers a lot of geography and different climate)

We already had ours actually this year on the 15th, we were about 2-3 weeks early though. The freeze combined For soybeans/corn to freeze, it generally needs to stay 28 degrees for about 4 hours, It wasn't quite a killing frost just yet but it definitely made an impact on the soybean yield that combined with virtually no rain in the last 3 months!

deffinately. Here's hoping for a quick start to the winter season, like 2007 and 2008. So long as there isn't a big rainstorm on October 23rd - day trip to Ottawa planned!

I heard that the leaves changing has more to do with decreasing daylight than frost, hence the fact that more northern areas see the change first. I've certainly noticed that Toronto's leaves change a few weeks later than Ottawa.

Very impressive wind potential for the middle of the night Thursday night. Very strong winds just off the surface could be mixed down with some shower activity embedded in the cyclonic flow. 40mph+ gusts look like a good possibility even outside of the showers.

Haven't been following the runs that much but does it seem like the timing has been pushed back?

Correct, it has def slowed down some, yesterday the strongest winds at 850mb were over the area between 18-0z thursday evening, tonights NAM run is much slower.

And FWIW, the NAM has a small area of 70kt winds at 850mb at 6z friday in central WI.

That could be a problem, although the overnight timing isn't that great.

Yeah the timing has slowed a bit, which isn't too surprising I guess. With such strong winds just off the surface combined with embedded showers rotating around the circulation I think the winds will be pretty impressive even at night. Looks like an all night window rattling kind of night lol. :popcorn:

I actually love nights like that, 40mph gusts all night.
