newtownwx Posted April 16, 2015 Share Posted April 16, 2015 Models are already slow with the precip. This thing is just going to sit and pump moisture. Let the dumping ensue! Link to comment Share on other sites More sharing options...
WeatherEmperor Posted April 16, 2015 Share Posted April 16, 2015 I'm in Boulder, CO right now and the snow is extremely heavy. Temp actually dropped 2 degrees to 32 in the last couple hours I believe. Not looking good for my drive home. Flakes have gotten bigger though, which could mean a change to rain eventually? Sometimes? I don't know. Link to comment Share on other sites More sharing options...
Chinook Posted April 16, 2015 Author Share Posted April 16, 2015 Snow has started to accumulate on trees and grass, but not pavement. I thought my area would be seeing rain right now. Link to comment Share on other sites More sharing options...

I thought my area would be seeing rain right now.The cad high doesn't erode until tonight on most models so not surprised in hindsight. GFS and Rgem show over 5 liquid in northern CO, you gotta get up to some place with elevation. Link to comment Share on other sites More sharing options...
newtownwx Posted April 16, 2015 Share Posted April 16, 2015 Radar is really beginning to fill-in. WV imagery suggests plenty of moisture primed and ready to go. Hang on, this could be a wild storm. Link to comment Share on other sites More sharing options...
Chinook Posted April 16, 2015 Author Share Posted April 16, 2015 We had some very large 1" width snowflakes falling quickly for a while. About 1" of snow is on the ground and 2" is on the roofs of cars. The snow has gotten much lighter. One of our stations recorded 0.36" of water in the rain gauge in a couple of hours. http://www.atmos.colostate.edu/wx/fcc/fccwx_plot_display.php Link to comment Share on other sites More sharing options...
mayjawintastawm Posted April 16, 2015 Share Posted April 16, 2015 We had perhaps an inch on the grass before the precip lightened and the sun angle increased. Pretty much all snow though, right around 32-33 F all morning. Rush hour traffic was horrible. Roads were slushy and in fact pretty slippery around 8:30, better now. APA had 0.29" melted from 6 AM-noon. The plants will be happy. Link to comment Share on other sites More sharing options...

Chinook Posted April 17, 2015 Author Share Posted April 17, 2015 The precip has changed to slushy raindrops for the last 4 hours. Lots of puddles. 0.5" to 0.7" water equivalent across town. Link to comment Share on other sites More sharing options...
Amped Posted April 17, 2015 Share Posted April 17, 2015 http://www.ericcalkins.com/ Estes park had about 2" on the ground until 15 minutes ago, now they have 3" Link to comment Share on other sites More sharing options...

huronicane Posted April 17, 2015 Share Posted April 17, 2015 I've got a bit over 2" in Northglenn. Tomorrow, now, that looks interesting Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
Chinook Posted April 17, 2015 Author Share Posted April 17, 2015 The Windsor tornado in 2008 formed with a large upper low much like this, (farther west, in Utah) with SSE winds at 500mb. This could be a reason to watch some of these areas closely, as the 00z NAM shows some excellent 2000 J/kg CAPE values around Wray, CO. Link to comment Share on other sites More sharing options...

mayjawintastawm Posted April 17, 2015 Share Posted April 17, 2015 5" of wet snow by 11 PM last night at our house (5650 ft) compacted to 4.3" of slop on the table in the backyard at 6:30 AM. Drizzle and very dense fog (100 yd visibility at best) now. Had a brief burst of sleet or very small hail about 10 AM, no thunder. Hard to tell which it was, as it merged with the slop.

huronicane Posted April 18, 2015 Share Posted April 18, 2015 Drove up by Fort Morgan to watch the storms roll through. Decent rotation with the storm, but could never produce. Had a few wall clouds though. On the way back to Northglenn, looked to the southeast and got a good picture of a developing storm with orientation completely opposite of typical, courtesy of the upper air pattern. And a Weather Channel producer asked to use some of my pictures on the air, but without access to TV, don't know if they made it on or not.

Chinook Posted April 18, 2015 Author Share Posted April 18, 2015 Nice. Those looked like little storms on radar. Oh well, if you can see a wall cloud without being hit by hail, that's a win. We had 2.2" to 2.4" storm total since Wednesday's sprinkles/graupel. That's a lot for us. I don't think we have seen a 2-day period this wet since the floods of 2013. Oh boy, was it ever fun to get raindrops blown in my face. It's like I never left Ohio. Link to comment Share on other sites More sharing options...
huronicane Posted April 18, 2015 Share Posted April 18, 2015 I kept driving through the storm and got into the extreme hail core. It wasn't terribly large hail, almost all of it was 1/2" or smaller, but the quantities were insane. It had accumulated several inches deep on I-76 and I saw a few accidents caused by people spinning out in it. Link to comment Share on other sites More sharing options...
Chinook Posted April 18, 2015 Author Share Posted April 18, 2015 It looks like the storm is over for now. CoCoRAHS snow reports on highway 72 seem to be 24" to 27" Link to comment Share on other sites More sharing options...
Chinook Posted April 18, 2015 Author Share Posted April 18, 2015 Talking about snow in the mountains, I saw quite a bit of snow above 5700ft today. It looks like 10-14" fell at 6000-7000ft Link to comment Share on other sites More sharing options...

boulderrr Posted April 20, 2015 Share Posted April 20, 2015 We easily got over 2' from this previous storm. A lot of it was compacted down by graupel. It was the first time in the last two winters that we would not have been able to get our vehicles out without digging. Driving from Ned to Boulder was crazy going from 2'+ to no snow in less than 10 miles. Link to comment Share on other sites More sharing options...
