Chinook Posted July 16, 2014 Author Share Posted July 16, 2014 Today, I may have gotten 0.3-0.4". We have some lighter rain with some rumbles of thunder. Link to comment Share on other sites More sharing options...
boulderrr Posted July 16, 2014 Share Posted July 16, 2014 We got some hail down in Boulder shortly after noon yesterday as well. The storms were really moving fast. Was hoping this morning's clouds would inhibit rain development this afternoon, but it doesn't look like that will be the case. Going to be a soggy evening at Red Rocks!

tacoman25 Posted July 17, 2014 Share Posted July 17, 2014 DEN has only recorded .66" so far this month. DEN sucks. 1.45" in my backyard, with several more heavy showers this afternoon. High of just 72. Link to comment Share on other sites More sharing options...
Chinook Posted July 17, 2014 Author Share Posted July 17, 2014 I estimate my area got 2.38" to 2.48" from Friday to Wednesday. That is higher than the July average for Fort Collins (1.71") Link to comment Share on other sites More sharing options...
Chinook Posted July 26, 2014 Author Share Posted July 26, 2014 The GFS and the NWS are predicting heavy rains for parts of Colorado. The highest QPF area is in the most drought-affected areas of SE Colorado. Link to comment Share on other sites More sharing options...

tacoman25 Posted July 29, 2014 Share Posted July 29, 2014 Radar is starting to look pretty serious around parts of the area. Still can't manage anything more than sprinkles so far in Boulder. Link to comment Share on other sites More sharing options...
Chinook Posted July 29, 2014 Author Share Posted July 29, 2014 This is pretty much the exact time of year when Colorado has had some famous floods of the past such as the Big Thompson Flood and the Fort Collins Flood of 97. I saw heavy rain for just a few minutes. Most of Larimer and Weld Counties have rain right now. Extensive street flooding reported in Windsor.

tacoman25 Posted July 30, 2014 Share Posted July 30, 2014 Pathetic showing so far at my house in Westminster, just .12" in the bucket. Places further north and east have seen a lot - reports of 2-3"+ on the eastern plains, with ongoing heavy rainfall. Link to comment Share on other sites More sharing options...
Chinook Posted July 30, 2014 Author Share Posted July 30, 2014 My place got 0.48" as estimated by FTG radar (maybe 0.38" to 0.48" in reality) and it is still raining a little. There was a sharp cutoff of rain around I-25. East Fort Collins got 1-1.5". Radar estimates show 3.5" at downtown Windsor. A few areas of Weld County and Wellington (Larimer County) had some slow storms yesterday- This was all north of Fort Collins and Greeley, we didn't get a drop. Colorado Springs (Fort Carson) had up to 1.7" on Sunday--localized flash floods south of CO Springs that day. I may have gotten 2.88+ in the last 20 days of July.

boulderrr Posted July 30, 2014 Share Posted July 30, 2014 Been coming down here in Boulder for much of the morning. Lots of ponding and streaming on the roadways. CU station showing 1.16" so far today. Link to comment Share on other sites More sharing options...
mayjawintastawm Posted July 30, 2014 Share Posted July 30, 2014 Nice tropical feeling rains. Reminiscent of last Sept except maybe 1/4 the intensity. About an inch at our house, no flooding. Could be worse! Link to comment Share on other sites More sharing options...
tacoman25 Posted July 31, 2014 Share Posted July 31, 2014 DEN ended up with a two day storm total of about 2.80". Pretty impressive. Finally got a lot of rain last night and today here: 1.95" total. This storm ended up performing about where models projected: 1-3" most places along the Front Range, with some higher amounts. Link to comment Share on other sites More sharing options...
Chinook Posted July 31, 2014 Author Share Posted July 31, 2014 I think my place got about 0.8" on both days Link to comment Share on other sites More sharing options...
ConiferMtnMan Posted August 13, 2014 Share Posted August 13, 2014 Been awful quiet around here for a while. Was a great summer with all the moisture around and cool weather. Only 45 days to snowmaking up at Loveland ski area. Love seeing the first dustings of snow on top of the mountains. It's not long now! Any westerners dreaming of winter with any first guesses on what it'll bring? I'm thinking a below average snow year for the mountains west of the divide, near or above on the plains and in the foothills. Still haven't learned the local climate well enough to say that's any more than a hunch though. Link to comment Share on other sites More sharing options...
Chinook Posted August 17, 2014 Author Share Posted August 17, 2014 As far as climate goes, I don't really have a particular guess. A few big Denver snowstorms have occurred with moderate or strong El Nino winters, but not all of them. My best snowstorms here were in 2006 and 2009, which were El Nino; moderate El Nino in 2006-07 and weak El Nino in 2009-10. (I think.) I know northern Colorado snow is favored with La Nina, southern Colorado snow is favored with El Nino. The CFSv2 keeps putting out winter seasonal forecasts that follow the standard moderate/strong El Nino precipitation forecast. El Nino looks to be weak, though. I don't even know if this CFSv2 forecast will be close. You never know, the CFSv2 may change its mind in a few weeks. They run this model with new initial conditions every 10 days.

Chinook Posted August 22, 2014 Author Share Posted August 22, 2014 After a relatively boring few days, we will most likely get several areas of heavy rain in NE Colorado. The shortwave kicking out from Arizona will provide the lift. Today's PW values in Colorado are very high, at 1.1-1.5" east of the Rockies. The 0-6km shear and CAPE also show some pretty decent values. My guess is that there will be a few severe storms between Denver and the northeast corner of Colorado. 300mb winds are now up to 55kt out of the SW, so this is a healthy sign that 0-6km shear will be large enough for some supercells.

andyhb Posted August 22, 2014 Share Posted August 22, 2014 moderate El Nino in 2006-07 and weak El Nino in 2009-10. (I think.) Other way around. Link to comment Share on other sites More sharing options...
Chinook Posted August 25, 2014 Author Share Posted August 25, 2014 The CFS says, bring on the rainy season in the West. So many of these areas are in drought, hopefully this is a very good signal. usPrecSeaInd1.gif The last 60 day precip % of normal plot shows that this (90-day) Jun-Aug CFS plot was actually pretty accurate for the Rockies Link to comment Share on other sites More sharing options...
Chinook Posted August 25, 2014 Author Share Posted August 25, 2014 This storm ought to delay a few planes in Denver. It has a hail core that is sitting next to the runways. Colorado will be in a new wet pattern in the next few days with a stalled front, and an upper low currently in Nevada. Link to comment Share on other sites More sharing options...
