Not to split hairs too much, but given COCORAHS and climate reports I'd move the purple and blue boundaries 10 miles or so northwest. Centennial Airport, the nearest climate site around 5 miles SE of the Denver line in Arapahoe County and about 3 miles SE of me, got 1.58" (122% of normal) in September and is at 0.11" so far in October.

North Metro has really been winning out lately... 0.19" here since 10/1 after about 1.2" in September.

0.12" here, pretty representative of most of the Denver Metro area by COCORAHS. Nice- helped incrementally with crispiness. BTW, though not mountains but relatively close- the hailstorm in McCook, NE yesterday was pretty devastating. 2 hours of hail up to 3" from a rare stationary supercell. I hope they got most of the crops in already!

Yes, I feel like since we moved to the Denver Metro in 2010, September and even October have shifted from real transition months to "warm, dry and dark" (the length of daylight is one thing that hasn't changed!) while April-May have just become more variable.

I love to see an argument on this page- don't think I've seen one in a long time, maybe ever! The New England forum has them like hourly.

Wow. And Centennial Airport got 0.40" for the month. Insane difference in less than 30 miles. We got 1.07" at my house, roughly 3 miles north of the airport.

Interesting! Thanks. Quite a few spots where there is 50-75% of normal (far SE Aurora) and 200+% of normal (Bennett) within 10 miles of one another. There is practically NO green on this map in the northern half of Colorado! Also, we got half an inch of rain this afternoon/evening.

What's interesting the last few days is that despite the seemingly random radar patterns, the distribution of heavy rain seems non-random- the places that get a lot of rain one day tend to get a lot on subsequent days. Would be interesting to see a cumulative map. We got another 0.07" for a total of 0.40" for the 5-day period.

APA (Centennial Airport) is at 0.30" for the month, which I think is pretty typical for the immediate I-25 corridor (say 10 miles either side) north of Castle Rock. We're at 0.36" at my house.

Beautiful fire prevention!!

Today could finally be better... or not... wow this monsoon thing and the AM stratus/PM nothingburger pattern is so weird. Let's see if we can double our monthly rainfall- would not be hard.

actually I'm halfway in between I-225 and Centennial Airport, where the blue dot is in this radar image from a few weeks ago. In the little finger of D2 drought on the map just SE of Denver. We did pick up another 0.11" early this morning, so that's good.

Quite the deluge here, with a 3-day total of 0.04" (0.08" for the month).

Airmass has cooled and stabilized north of the Palmer Divide. So convective possibility has disappeared. Swing and a miss for strike one. Need something to generate lift, or upslope, or something.

Will be interesting to see what happens with this pattern change. Over the last 60 days we've had 0.34" of rain. Ground moisture in non-irrigated spots is nonexistent. 40+ year old trees in the neighborhood are very stressed and some are dying.
