At Stevens Field the high yesterday afternoon was 41 and today we hit 32. The low this morning was 27. As of 6pm, the temp at the airfield is already down to 24. Winds at the airfield peaked at 35mph today. Winds on the Wolf Creek summit/Lobo Overlook sensor peaked at 56mph. Wind chills up there this afternoon were in the -20 to -25 range – brrrrr!
|Average High||Record High / Year||Average Low||Record Low / Year|
|44||58 / 1973||10||-25 / 1952|
Precip summary… Snow started this morning about when most of the CoCoRaHS observers do their daily reports. Snow totals will be in tomorrow’s reports, but I expect they’ll be under a half inch – disappointing. Wolf Creek reported 2” this morning – also disappointing.
The central and northern Colorado mountains did quite well. The Colorado Avalanche Information Center reported up to 20” and issued an avalanche warning for a few mountain ranges.
There is nothing on radar in our region this afternoon.
This evening through Thursday evening… Another transient ridge will move through with drier air. Tomorrow morning will be the coldest of the season so far. The cold spots could dip below zero – brrrr.
Thursday night through Monday evening… An active and complicated pattern is setting up. The big subtropical high over the Gulf will slowly weaken and move south. This will allow the West Coast systems to drop a little farther south before they move into our area.
Two troughs are expected. The first will move through Friday evening and take a similar track as today’s system. The second will move through Monday evening and take a more southerly, more favorable route.
Upper level flow will stay primarily out of the southwest with a few brief periods of more westerly flow. Southwest flow will continue to push waves of moisture and energy through our area while the brief periods of westerly flow will give us a bit of a break. Unfortunately the southwest flow will also push periods of warmer air in too.
It’s going to be a complicated forecast with snow levels bouncing around. Precip will fall on and off and be mostly light. But the long duration, nearly 4 days, will result in accumulating snow.
*The best chances for precip are sunrise to sunset on Friday and Sunday afternoon to Monday evening. Saturday will be a lull with scattered showers. Snow levels will be at their highest on Sunday afternoon up to 8,500ft.*
My initial snow forecast for Friday through Monday evening…
Valley below 7,500ft: 2-4”
Valley above 7,500ft: 4-8”
*** This snow will fall over a four day period mixed with intervals of afternoon rain. Snow amounts will vary considerably and are dependent on the surges of warmer air. ***
