TT-SEA Posted August 24, 2017 Report Share Posted August 24, 2017 Rained overnight... still drizzling now. Wish the SEA radar was functioning. You would think they would use the 3 months of dry weather to get the regional radars in perfect working order so they don't keep failing during the 9 months of rain.

TT-SEA Posted August 24, 2017 Report Share Posted August 24, 2017 Harvey is evil... that thing moves into SE Texas at a decent pace and then just completely stalls and spins over the same area for at least 5 days. The lack of a western trough to pull it up and out to the north seems to the problem. It just runs into a western ridge wall. Total rain through Wednesday... and its still going at that time.

Front Ranger Posted August 24, 2017 Report Share Posted August 24, 2017 Record breaking SSTs noted on the northern/off-equator portion of the WPAC warm pool, right as the MJO arrives. Given the cool tropical EPAC, the west is probably gonna roast, at least through the first half of September. There was a pretty good signal for ridging in NW Canada from my main analogs going into summer. The result was western Canada being very warm, but much of the West ending up near normal. It will be interesting to see if that develops, as it would still line up with the tropical forcings. June: Average to a little above average month for PNW. Composite analogs suggest ridging for the month is centered just offshore, meaning generally dry conditions for the PNW and cooler/wetter weather than normal inland in the West. Near normal to slightly warm in the East. Best chance of well above normal weather in the SE. July: Primary ridging remains just offshore but at times right over West Coast. Warmer than normal conditions likely right along the coast, considerably cooler inland West and northern plains. Warmer than normal weather likely along the East Coast. August: Warmer than normal throughout most of the West, much cooler for the eastern half of the nation. Sprawling, but fairly weak ridging over much of the West for the month, with troughing in the NE likely. September: Decent signal for ridging up into NW Canada. Near normal temps for much of the West, with warmer temps in the SE, near normal in NE. Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...

I found that intriguing because I couldn't find any cool Septembers in years featuring late-blooming WPAC warmth, particularly during -QBOs.

Phil Posted August 24, 2017 Report Share Posted August 24, 2017 We started the warm season with raging EPAC warmth and an anemic IPWP (which favors cool/zonal flow across NW North America) so I based my cool June/July forecast (and warm August/September forecast) on the idea that it would take until the middle of the summer to transition away from the warm EPAC and build heat in the WPAC, while transitioning into a relatively modest -ENSO. That transition ended up completing itself June, much faster than I'd thought, so we tightened the WC/flipped the ET wavetrain very quickly.

I found that intriguing because I couldn't find any cool Septembers in years featuring late-blooming WPAC warmth, particularly during -QBOs. I didn't. The only change I made was reducing the odds of a warm September in the West. My original forecast was for near normal in the West, because the only real signal I saw either way was for ridging in NW Canada. After the first half of summer pattern became clear, it began to look less likely that Sep would end up warm. As I reiterated before, I've been going near normal to a little below for the PNW in Sep. +.5 to -1 for anomalies for most stations. Quote A forum for the end of the world.

Front Ranger Posted August 24, 2017 Report Share Posted August 24, 2017 Even if Sep ends up really warm in the PNW, it would still support my overall outlook for the summer. It's a seasonal forecast, so that's more important to me than any one month. Now I just need the middle of the country to remain coolish and the SE to heat up in September.

I have at least five screenshots confirming this. Whatever happens, I hope you're academically honest about it.
