We seem to have fallen through both holes in the swiss cheese, with 0.06" rain total the last 2 days.

It was noticeable pretty much every day since last Friday around the Front Range, except Sunday which was a lot prettier. Figures that the one year we have a wet Spring, we get smoke from other places.

Congrats and welcome! I don't think we have any posters from WY so that's especially good. Also, noticed you're from Fleetwood- we lived in Allentown (actually Emmaus) for several years in the mid 90s and my wife grew up in Bethlehem.

And DIA was a relative low-precip site compared to several others in the Metro area. Places that got the brunt of the thunderstorms received 1-1.25 inches on the 10th, and much of the south and east metro area received 3.7-4.3 inches on the 11th. So this was really significant, especially because on the 10th the QPF predictions were mostly between 1.5 and 2.5 inches for the entire event. The Cherry Creek Reservoir level went up 9 feet over the last 3 days. This is 1.8 feet short of the 3rd highest level ever, in 1983, and about as high as I have seen it in our 13 years here, comparable to the September 2013 flood. This is also a special event because prior to the rain, it was at its lowest point in several years due to the dry winter.

What we are all thinking.... if this had come two months ago!! Sump pump working overtime.

And now the total is up to 4.79" at one and 5.02" at another. Still raining, less hard. I think it took about 7 months to get the previous 5" and this time it took 32 hours.

The two PWSs nearest me (my rain gauge still broken) have had 3.75 and 3.92 inches of rain in the last 26 hours. I think that's the most in that short a time since the 2013 floods.

Did that once to find a 2" stone, while it was hailing, with a bike helmet for protection. Wife thought I was nuts. But it was warm and I didn't want it to melt.

Round 1: A few 1 inch hailstones and a whole lotta rain. We were in 2 tornado warnings inside of an hour I think, but just radar indicated.

I think so- I really liked their short term discussion. Struggling to get out of the soup here and get a little heating.

Here we go, severe season started with a bang last night north of Denver and the current main event might be today. Enhanced risk for severe for the immediate Denver metro and northeast. Keep those cars inside, sports fans.

I'm going to start a spring-summer thread with today's interesting scenario as the first post. 8 pages + 1 post for all of fall and winter... we could use some more traffic! 48.8" snowfall for the 22-23 season at my house, barring anything the rest of May.

There was a narrow N-S band of 1.4-1.8 inches just north and south of DIA from Weld County south to SE Aurora, according to COCORAHS.

Two things really surprised me about that storm: 1) the snow level for real accumulation was much higher than forecast- looks like about 7500 feet; and 2) the total precip was much, much less than forecast south and east of the Metro area. Heavy precip over 2 inches was confined to the Pueblo area. Even SE Colorado got shafted. If it hadn't been for the convection earlier in the day, it would have been bust-o-rama for everyone.

Around an inch of rain here from everyone else's home weather stations, the most in just about 8 months. Temp 39 and it doesn't seem likely that we'll see a single flake. Looks from radar that the snow level is right around 6200 ft.

Some really nice rain for about the last 4 hours, even before the "main event" (or non-event for us). Of course my rain gauge decided to jam right after it started. Have to go up on the roof tomorrow.

The Keenesburg tornado was a landspout. There was some video someone took from a car, looks like they were on I-76. Little bitty thing. We had some nice sunshine today that yielded just enough instability to create some thunderstorms.

Models coming in more south again, with less QPF locally and some with a precip hole over the Denver metro. Why am I not surprised. Good for SE CO though.

OK now GFS says 4" of snow and only 0.88" QPF for my house (like half of the 18z run) while NAM says 14" of snow and 2.5" QPF on the 00z runs. GFS ensemble is 1.4" QPF but only 3 inches of snow (that actually sounds pretty realistic). SREF mean is close to the GEFS. NAM is nuts. Bedtime.

something looks weird to me though with that- I can only see Euro ensemble with free pivotalweather, but the maximum QPF (like Pueblo/Walsenburg) looks to be too close to where the 500 mb low tracks, which is not too far from where it tracked last run, though it is faster this time. But I certainly do not speak fluent modelese.

Smokeybandit, I think this one's for you... I'll be right on the hairy edge at 5650'. Honestly big snow this time of year doesn't excite me quite as much as it would in March, but I'll take it.

3.2" for the final today as we were under that very last band of snow that only quit around 1 PM. The next week system looks really interesting- sometimes (May 21 last year anyone?) they wind up colder than billed, which could make for a notable Tuesday night/Wednesday. Good thing few trees have leaves yet. After this week we can make a warm season thread, but maybe not yet.

Nice 2.5" of snow last night, the most moisture at one time in a couple months. Pretty.

The story of the Spring to date.

GFS is like a 6 year old kid... entertaining, but enough to give you a headache sometimes.
