He should use that red crayon as a pole and shove it in his conduit.

It's too bad Hillary didn't chose him as a running mate.

A ridge offshore will lead to cooler than average temperatures in the PNW. There's really no support for any sustained ridging in AUG outside clown range modeling that has shown no predictive ability whatsoever this summer.

Jim is one of the nicest guys here and yet he seems to always get crap he doesn't deserve. Go back into your hole please, thanks.

While I doubt heat domes like the ones east of the Rockies can occur on this part of the continent, that doesn't mean there could potentially have been heat events with some characteristics of a heat dome--high pressure smothering a large area and keeping out any cooler weather or moisture. August 1981, July 1994, July 2006, July 2009, August 2012, June 2013 might be candidates.

Brett and his red crayon have been spot on this summer..

I recently started a thread on heat events, inspired by all the talk of heat domes in the central and eastern U.S. as of late. While the following is related to heat domes, I thought it was more appropriate to post in here. A side effect of heat domes is the "ring of fire" phenomenon, in which heavy thunderstorms develop along the periphery of a hot air mass. Examples include the "super derecho" in 2012. My gut instinct is that geography gets in the way of "ring of fire"-esque events. The Rockies block moisture from the Gulf of Mexico while the Cascades block surface moisture originating from the monsoon down in Arizona. What's more, there's a lot less 28+ degree water in the Gulf of California and the tropical eastern Pacific, compared to the Gulf of Mexico as can be evidenced by NOAA's SST maps. I think that's why thunderstorms in the western U.S. tend to be dry, and we don't get the kind of drenching storms that they get east of the Rockies. You won't get them unless the source of moisture is something like the remnants of an eastern Pacific hurricane (like 7/20/12), or there's a freak progressive event like 8/6/97, 9/5/13, 8/3-5/99, 6/22/93 or 8/12/14.

Well D**n, if he said it then it must be true

The "typhoon rule" says nothing as to the location and orientation of the downstream cyclonic breaking. I don't know where this idea that recurving typhoon = western ridge originated from, but it's demonstrably false. There are many example of recurving typhoons that were followed by extended periods of western troughing. It all depends on the nature of the wavebreaking response (assuming one even occurs to begin with).

Based on what, exactly? Sounds sort of like wishcasting to me. Clown range modeling isn't the route I'd go this year. Remember all that 100+ degree heat consistently modeled for last week? What happened to it?

Had kind of a cool event yesterday here in the Omaha metro. It was very hot and humid yesterday 94 with a 78 degree dewpoint and a cold front was moving through. Luckily, there wasn't a lot of shear to produce a lot of severe storms, but we still had 2 tornadoes in the area. Both were classified as landspouts as the storms they formed from weren't true supercells. Shear was running only about 20 knots I believe. However, the 2nd tornado was actually a waterspout as it dropped right on Lake Manawa on the southern side of Council Bluffs, IA. It lasted 15 minutes and was almost completely stationary! I've attached some links to videos and pics. http://www.ketv.com/news/photos-storm-rolls-through-thursday/41057356 http://www.ketv.com/news/closeup-video-of-tornado-over-western-iowa/41058986 http://www.ketv.com/news/waterspout-churns-over-iowa-lake/41066412 https://www.youtube.com/watch?v=Ixu7Ahw5T_4 https://www.youtube.com/watch?v=gYqa7P6pBW0

Wonderfully cool today, with a high of only 74. Tomorrow should be even a couple degrees cooler, with more widespread showers. I'm having a BBQ Saturday, and with my luck that will be the one day with serious precipitation at my place this summer.
