Vandy Posted June 30, 2012 Share Posted June 30, 2012 One might think with the East getting heat we'd get a break. I suppose 90 was a break... This week's heat looks to be worse. Perhaps a few degrees cooler but dews in the 40s-50s as the afternoon moisture rolls in. Link to comment Share on other sites More sharing options...

Vandy Posted July 2, 2012 Share Posted July 2, 2012 I was up at Chasm Lake by Long's today and for about two hours in the late morning we had a dense smoke fill the valley, which then began to let up. Anyone know the source? Wildfires in Utah? Link to comment Share on other sites More sharing options...
mayjawintastawm Posted July 3, 2012 Share Posted July 3, 2012 101 at DIA today. 6th record high out of the last 11 days. Also the 8th day 100 or above this year... and it ain't even close to the hottest time of year! Robust, I would say. Link to comment Share on other sites More sharing options...

Chinook Posted July 3, 2012 Author Share Posted July 3, 2012 I am going to have to see it to believe it. The models do show higher moisture and chances for thunder soon. Actually precip chances look good this week and seem to show a "dirty" ridge in the medium range. Typically precipitation maxes out between July 20 and August 5. We get about 15 days worth of monsoon and flash flood potential. Things change every year though. It is not as predictable as the true North American Monsoon.

Chinook Posted July 3, 2012 Author Share Posted July 3, 2012 TEMPERATURES: THE AVERAGE TEMPERATURE FOR THE MONTH WAS 75.0 DEGREES WHICH WAS 7.6 DEGREES ABOVE NORMAL. THIS MAKES JUNE OF 2012 THE HOTTEST JUNE ON RECORD. Fort Collins had the warmest June on record, with 6.2 degrees above normal. There was 0.61" of rain. My house got considerably less rain, around 0.2" to 0.4". Fort Collins broke high temperature records on June 22, 24, 25, and 26. We had 100, 101, and 102 degree days on June 23-25. Evaporation was much above average. Something may have been a little off with that 0.61" rain total. This picture is a plot from the weighing-bucket rain gauge. This rain gauge saves information on the computer and you can plot it on the internet. It looks like it is 0.32 or 0.33". The official total of 0.61" is from the human observers using the 8" standard rain gauge. I don't know why they would be much different. It's not like snow was sitting on top of the rain gauge or something. Link to comment Share on other sites More sharing options...

It is not as predictable as the true North American Monsoon. Looks like a fairly decent setup for summertime precip. Low-level easterly flow should help the foothills cash in.

mayjawintastawm Posted July 6, 2012 Share Posted July 6, 2012 Pretty interesting BOU AFD this morning. Models are really really wet. Forecasters are meh. Given the way it looks and feels and how silly the GFS has been lately, I'm inclined to go with the meh. Temps have been overperforming and dewpoints underperforming- seems hard to break.

Chinook Posted July 6, 2012 Author Share Posted July 6, 2012 We are getting some heavy rain over the High Park Fire. Looks like storms may stall over Larimer County. Some models show maximum rainfall late at night here. Link to comment Share on other sites More sharing options...

Chinook Posted July 7, 2012 Author Share Posted July 7, 2012 I already had 0.94" in an hour and a half (3:30-5:00). It's about to rain again. There was a mudslide at Hewlett Gulch, possibly hitting Highway 14. This is the heaviest rain I have seen since 2011. This is 1/3 as much rain as we have had all year (1 vs. 3.3).

mayjawintastawm Posted July 7, 2012 Share Posted July 7, 2012 wow, and we've managed to eke out maybe 0.2" if I hold the rain gauge just right. DIA has had nada measurable. Foothills/mtns, Palmer Divide, and north are the winners. Better than nothing though and the windows are open!!! Link to comment Share on other sites More sharing options...
Amped Posted July 7, 2012 Share Posted July 7, 2012 Hopefully nobody is flooded. Narrow canyons are prone to flash flooding, and the long term drought won't help much. Link to comment Share on other sites More sharing options...
Chinook Posted July 7, 2012 Author Share Posted July 7, 2012 FTG radar says that Fort Collins has gotten 0.3" to 2.10". I estimate 1.16" here at my place. Fort Collins-CSU had 0.76" as of 8:00 and we have gotten some more (0.10") since then, so maybe 0.86" for Fort Collins-CSU. Mesonet stations have 0.20 to 0.65". That's a large range. I guess we will see more detail on precipitation when we can look at the CoCoRAHS map tomorrow. It has been so dry that there hasn't been more than 1" of rain for a storm total since September or October. We got about 1" of liquid equivalent from snow on maybe 3 occasions. I am seeing a little bit of lightning in the distance. Link to comment Share on other sites More sharing options...
icebreaker5221 Posted July 7, 2012 Share Posted July 7, 2012 Cocorahs spotters report anywhere from 1.82" in the SW corner of Boulder county to 0.12" in the NE corner, with most places around a half inch for the day yesterday. Last night was one of the most persistent, steady stratiform rains in months! Link to comment Share on other sites More sharing options...
marsman Posted July 7, 2012 Share Posted July 7, 2012 Is this crazy outflow I'm seeing on the radar moving out from Pueblo and Colorado Springs? Taken today, 4:30pm local time.

Chinook Posted July 8, 2012 Author Share Posted July 8, 2012 We got another 1 to 1.5" here. FTG radar says there is 4" at Wellington and 5" at Masonville. Link to comment Share on other sites More sharing options...

More lines like this were visible on the WunderMap from the storms east of Denver. Yup, outflow from storms around here can easily go 50 miles or more without anything to stop it. Before things got wet the past few days, we'd often have a period in the early evening where it would go from calm and hot to a little cloudy, 10 drops of rain, and 40 MPH gusts for a few minutes as a boundary passed. A few weeks ago I was in a plane flying into DIA and during final approach the wind went from a 5-10 knot headwind to a 20 knot tailwind. Fun. Good thing I wasn't flying the plane!

Chinook Posted July 8, 2012 Author Share Posted July 8, 2012 Most of Fort Collins got about 0.8" yesterday. It was moderately heavy for a long time. I think my place got 1.16" and 0.56" on the last two days (total: 1.72"). Areas around here are above and below that 1.72" for the last two days. (2.19" at Fort Collins CSU for July so far.)

From BWI by any chance? Was on a flight into DEN that was diverted to Colorado Springs after 3 or 4 landing attempts. Pilot aborted the first landing attempt with less than a minute to go. Flaps were fully extended, unsure if the gear was down. Made a hard bank right to abort, before we hit bad turbulence. I assume there was a downburst in the landing path. Don't know if it was the pilot or the tower that called it off, but may have saved lives by doing so. Link to comment Share on other sites More sharing options...
mayjawintastawm Posted July 9, 2012 Share Posted July 9, 2012 No, from DCA...close! Not much turbulence but a nice push at the end. Good thing they make runways long here- we used 11,000 of the 12,000 feet and were flying an A320. Wondered if we would have gone around if we were in a bigger plane.

Chinook Posted July 9, 2012 Author Share Posted July 9, 2012 We had some more heavy rain last night, without much thunder. I may have gotten about 1". Total rainfall was variable throughout the city.

My grass is happier and I turned off the AC for 5 days. Now we are back into at least moderate heat for a few more days though. Oh well, it's summer.

Chinook Posted July 13, 2012 Author Share Posted July 13, 2012 Looks like northern Arizona, Utah, eastern Nevada have around a 70% chance of thunderstorms. I think a lot of that area will get over 0.2" in the next two days. The HRRR shows considerable night-time rain for Utah. Hopefully the moisture spills over from the western Rockies to my area.

Chinook Posted July 20, 2012 Author Share Posted July 20, 2012 It was actually a reality. It was -15 on December 9 2009. I actually like it when it's 90 degrees and dry vs. -15 degrees. Link to comment Share on other sites More sharing options...
