mayjawintastawm Posted September 24, 2017 Share Posted September 24, 2017 we got around 0.7" last evening, going from very dry to above normal for Sept in 5 hours. Cold too! Installed sod on part of the front lawn today, good timing. Those suckers are heavy. Link to comment Share on other sites More sharing options...
raindancewx Posted September 25, 2017 Share Posted September 25, 2017 GFS has a good dump of snow roughly down to Wolf Creek in Colorado. Nice to see since we're still in September. This rain event - if it verifies - over the next week would be useful for cooling off October from the torch last year. We're already +25% on precipitation this year on 2016 to date, pending any more by September 30th. I was playing around with La Nina temperatures in my area. One of the better predictors believe it or not is the number of days at 87F or more from Apr/May to Sept/Oct. Colder La Nina winters tend to follow the years with a lot of hot days, hotter La Ninas follow the years with relatively few. We've had 96 this year, up from 83 last year. Of the 18 La Ninas with 89 or fewer days at 87F or hotter, only one is cold (<=47.5F DJF), 11 are hot (>=51.5F) in the winter. Of the 9 La Ninas with over 89 days at 87F or hotter, only one is hot, but three are cold. It's a ~61% v. ~11% difference for the hot winters, P value of ~0.01 in terms of safely rejecting that it makes no difference on DJF highs. I'm not expecting a cold winter here, but "cold for a La Nina" seems somewhat likely, La Ninas are ~50.7F here. Blend of 87F days, the cooler AMO, and solar activity implies about 49F for this winter, down from 52F last winter. Every month from Oct-May averages a lower mean high after a lot of 87F days here in La Ninas, even though the mean of the years with a lot of 87F days is 1981, while the mean of the years with fewer 87F day is 1976, so I think a cooler period overall is relatively certain, even if it still ends up above average.

mayjawintastawm Posted September 27, 2017 Share Posted September 27, 2017 This may seem laughable to anyone who lives north of about 41 N or east of about 102 W, but I can't recall a 5 day period since we moved to the Front Range in 2010 that was as cloudy as this.

Chinook Posted September 28, 2017 Author Share Posted September 28, 2017 My area had partly sunny conditions on Monday and Tuesday. Today, we had a rainy morning with maybe 0.05" to 0.10". With the cool temperatures, the rain really soaks in, and stays on the pavement for a while, much unlike the summer. Link to comment Share on other sites More sharing options...
raindancewx Posted September 28, 2017 Share Posted September 28, 2017 Nice and cold down here (for Sept), been hovering at ~50F with the state getting a good soaking rain event. Mountains got snow, including those east of the city. We're at 0.67" today as of a little after 9 pm and still raining. NAM has another inch or more for the city by the end of September. I had 1.25" for ABQ (+20%) for Sept so not surprised in my Summer outlook (from May) - am a bit miffed it took this long, we don't usually get rain events this big in the Fall, they tend to happen earlier in Sept if they do happen, when the E Pac Hurricane Season peaks.

Chinook Posted September 28, 2017 Author Share Posted September 28, 2017 Baseball note: the Colorado Rockies may be a bit closer to clinching a wild card spot. In the last several weeks, the Brewers and Cardinals have been close to the Rockies wild card position. I don't think the Rockies will get the win if they face Arizona in the wild card game. They have been a relatively average baseball team since the All-Star Break. Charlie Blackmon broke 100 RBIs as a leadoff hitter. Link to comment Share on other sites More sharing options...
Chinook Posted September 28, 2017 Author Share Posted September 28, 2017 We have had another wet morning here. This time, the rain may have started at 1AM or 2AM. Colorado, New Mexico, and the Plains have picked up some pretty reasonable rainfall amounts. Some areas of Texas have had over 6" in the last week. 3-4" of rain is well above normal, as many areas may average 1"-2.5" for the month of September. Note: the white area west of the Continental Divide is missing data. Link to comment Share on other sites More sharing options...

I don't know what it is about Arizona, but they really seem to have the Rockies' number on a regular basis. Seems like every time the Rockies play them, hitting disappears. It was like Red Sox- Tampa Bay when I lived in MA. Watching a Rockies- Diamondbacks game is a bit like hitting myself in the head with a hammer, again. Blackmon is one great bright spot though.

It's been pretty wet here, and the models have good rains through Saturday now. I'm annoyed with them at the moment - they screwed up the rain total for yesterday. We had a big thunderstorm complex just after midnight but it was counted for 9/28. I pointed it out but they didn't fix it. We've had 1.5-2.0 inches since 9/27 in most of the metro, and so another big round of rain probably will do some flooding. Even the CFS seems to be catching on that it isn't going to be hot/dry out here in October, given the rains coming next week and the saturated ground. I had a wet monsoon in my Summer outlook (from May) which ended up verifying, I think we're around 4.50" in the city now, pending more tonight or Saturday. 1931-2016 mean is 4.31" and I had 5.75". The cold season months here are pretty sensitive to big rain/snow events, so we should be in for a pretty nice October - no torch like last year.

Chinook Posted September 30, 2017 Author Share Posted September 30, 2017 All this talk about warm temperatures in the Lakes/Ohio Valley subforum, and it could snow in mid-Wyoming on the same day. Models agree that the snow should be in many parts of Wyoming next week. Note: my old home town of Toledo had 6 straight days of 90's this week. That means that 6 out of 11 of Toledo's 90 degree days for the year were in the past week and a half. Link to comment Share on other sites More sharing options...
raindancewx Posted September 30, 2017 Share Posted September 30, 2017 CFS has amplified in a pretty massive way for October over the last few days, including showing most of the Midwest in a torch pattern, with cool / near normal temps in our area. Trending toward much lower heights in the West. October was very hot here in 2016 - had it 6F cooler for this year in my Fall Outlook (highs). Canadian will be out tomorrow, should have a good idea. It did OK for Sept - had the SE cool with the West warm, but didn't figure out there would be a big time cold snap at the end of the month in the interior / mountainous West.

Heavy snow with thunder rolled in around 2pm. I was ready for the snow, in fact that is why I went. But the lightning sent me back down Edit: Just saw that I am under a WWA for up to 8".

I like roughly the SW half of Montana as 1-3F below normal highs for the winter, but still tinkering with it. Severe drought in NE Montana makes me hesitant to have that area pretty cold (for highs, lows are a different story!). A lot of the years I like are pretty cold in NV/UT - sort of in the area where the recent late September cold snap was. Link to comment Share on other sites More sharing options...

mayjawintastawm Posted October 5, 2017 Share Posted October 5, 2017 Have to say it was not an unusual pattern for the Rockies this season in maybe 1/3 of their games. Too bad it had to be THIS game. And yeah, let's wait another couple weeks for the snow, shall we? Though if the Rockies had won, I'd be rooting for a snowstorm at Coors... home field advantage?? SE low level wind would favor Chinook and ValpoVike, not me. But that's OK. Link to comment Share on other sites More sharing options...

I think Arizona should be a good team to watch and root for. I hope J.D. Martinez hits a home run vs. the Dodgers. J.D. started hitting well when he joined the Tigers, and started hitting even better when he joined Arizona. Link to comment Share on other sites More sharing options...
raindancewx Posted October 5, 2017 Share Posted October 5, 2017 With CPC updating both ERSST V.4 and ERSST V.5 for Nino 3.4, I keep wondering how the winter will end up being classified? The differences are pretty stark now - by V.5 we're Cold Neutral in JAS, -0.1C, since it has a colder 30-year base period. But in V.4 we're -0.5C, with the warmer 30-year base period. I keep wondering if they'll cave to anomalies by V.5 colder, since everyone was using the V.4 means for projections? I think this is part of why you have such a large spread in the models for the winter, some probably automatically use the newest data sets and others don't. Also: Houston over Boston in 5 Cleveland over NYY in 4 Cubs over Nationals in 4 Arizona over LA in 5 Link to comment Share on other sites More sharing options...
