At Stevens Field the high temperature so far today has been 42. The low in the last 24 hours was 33. Winds in the last 24 hours peaked at 21mph at 9:15am this morning. We hit 25mph in O’Neal Park around sunrise.
|Average High||Record High / Year||Average Low||Record Low / Year|
|47||72 / 1989||15||-8 / 1948|
Precipitation summary… Wolf Creek reported 9” of new snow. Temps up there are in the mid-20s so it’s dense snow. Here in the valley, cold air hung on longer than I expected resulting in more snow than I expected. Liquid equivalent amounts were in line with my forecast. Check out the CoCoRaHS reports below…
Rest of today through Sunday… The “atmospheric river” event is on-going. It’s weakening and slowly moving south. Chama, Dulce, and Farmington will likely get more precip than us over the next 24-30 hours.
The bulk of the precip is done in the valley but snow will continue to fall in the mountains. Showers in the valley will be more hit and miss this afternoon through Sunday afternoon. A stray thunderstorm or two is also possible this afternoon and tomorrow afternoon.
Temps… Saturday and Sunday highs will be in the low to high 40s. Tonight lows will be in the mid-20s to mid-30s. Lows Sunday will be in the high teens to mid-20s.
Winds… Winds today will peak in the 20-25mph range. Winds tomorrow afternoon will peak in the 15-20mph range.
Hit and miss showers (convective activity) will help bounce snow levels around considerably until this evening. Most forms of precip are possible with the showers: rain, snow, graupel, and even small hail. Colder air will gradually move in overnight and snow levels lower to around 7,000ft by Sunday morning. As snow levels lower tonight, moisture will decrease, and showers will be more hit and miss.
Additional precip amounts…
Valley below 7,600ft: up to 0.15” of precip with up to 1” of snow
Valley above 7,600ft: up to 0.25” of precip and up 2” of snow
Mountains above 9,000ft: 8-14”
Precip will be spotty in the valley.
*** There is a WINTER STORM WARNING for the southwest San Juan Mountains for elevations above 8,000ft for a total of 10-20” of snow with up to 30” possible along with winds to 50mph valid until 6am Sunday. ***
*** The Colorado Avalanche Information Center has issued an AVALANCHE WARNING valid until 7am on Sunday. Large and dangerous avalanches will occur naturally and will also be very easy to trigger. ***
*** Be careful of roof avalanches! ***
Monday and Tuesday… Transient ridging will dry us out a bit. Monday afternoon spotty showers are possible, mostly over the mountains. The lucky spots in the mountains could see another 1-3” of snow and lucky spots in the valley could get up to a half inch. Most of Tuesday will be dry. Late Tuesday night clouds and the chance for showers will increase, especially over the mountains.
Temps… Highs will be in the mid-40s to low 50s. Lows Monday will be in the high teens to high 20s and on Tuesday they’ll be in the mid-20s to mid-30s.
Winds… Afternoon winds will peak around 15mph.
Wednesday through Thursday night… The next system will move through. The storm track, storm energy, and moisture are all lining up for another good round of precip. The amount of warm air and snow levels are going to be challenging again.
Temps… Wednesday highs will be in the low to high 40s and lows will be in the high 20s to mid-30s. Thursday highs will be in the high 30s to low 40s and lows will be in the high teens to mid-20s.
Winds… Peaks winds will be in the 15-20mph range.
Snow levels… Will bounce around the 8,000ft to 8,500ft range Tuesday afternoon to Wednesday evening and then gradually lower below 7,000ft by Thursday morning.
Valley below 7,600ft: 0.3” to 0.60” of liquid equivalent and 1-3” of snow
Valley above 7,600ft: 0.50” to 0.75” of liquid equivalent and 3-6” of snow
Mountains above 9,000ft: 10-18” of snow
** The forecast models still indicate a wide variance in precip totals so I’ll adjust them as the data gets better. **
Remember to “spring forward” your clocks tonight.
My next post will be tomorrow. I’ll include a storm summary and snowpack update.
