Premium BoulderCAST Daily – Sat 12/28/24 | Gusty downslope winds on the Plains and snow in the mountains

It will be a gusty afternoon across the Plains as west-northwest winds interact with the terrain and cause strong downslope flow. Height and pressure differences from west to east will also fuel these winds. The downslope winds will favor highs in the lower 50s, again on the mild side. Both the HRRR and NAM-NEST show surface wind gusts out of …

Premium BoulderCAST Daily – Fri 12/27/24 | Quiet on the Plains – Snow in the Mountains

The week ends on the quiet side under a mixture of mostly cloudy skies and a few pockets of sunshine. Highs should reach the mid to upper 40s on the Plains, coolest in Boulder with some low to middle 40s per the latest NowCAST update. Meanwhile, west-northwest flow will persist over the higher terrain, with some 3 to 7 inch …

Premium This Weekend in Colorado Weather: Moist northwest flow produces on-and-off Mountain snow, but mostly dry & mild for the lower elevations

Yesterday was only the second Christmas in recorded history with Boulder reporting exclusively measurable rainfall, but not a single snowflake. That last and only prior occurrence of a rainy Christmas was way back in 1942. https://twitter.com/BoulderCAST/status/1872054051107717333 Be careful out there this morning as skies have mostly cleared overnight with temperatures dropping several degrees below freezing. Everything that was wet from …

Premium BoulderCAST Daily – Tue 12/24/24 | A mild & sunny Christmas Eve, but a chance for late-day rain/snow showers on Christmas Day after 3PM

The weak shortwave disturbance that moved through overnight brought a wave of light snowfall to the Mountains. It wasn't a lot of snow, but it was unsurprisingly enough to close down I-70 at a few of the passes due to slick roads and copious Christmas collisions. Several ski resorts are reporting 2-4" of snow overnight, with Loveland leading the way. …

BoulderCAST Daily – Sun 12/22/24 | Still quiet today but watching snow for Christmas

Temperatures today will remain in the lower 60s, but we will see an uptick in clouds today ahead of a system to our west. We are still watching a system coming in Wednesday for Christmas, with a cold front dropping down Christmas evening. The GFS has been trending wetter with snow chances on the evening of the holiday, with some …

Premium BoulderCAST Daily – Sat 12/21/24 | Staying mild this weekend in the low 60s

Temperatures this weekend will remain on the mild side with lower 60s for the Denver Metro area. This afternoon, expect lots of sunshine and light winds. Lows tonight will dip into the lower 30s. We will see similar conditions on Sunday. On our weekend outlook, we discussed the chance of snow on Christmas. The GEFS precipitation forecast is shown below. …

Premium BoulderCAST Daily – Fri 12/20/24 | Unseasonably warm today but Arctic air is not far from us

Warm Chinook downslope winds this afternoon will favor unseasonably warm highs in the lower 60s over much of the forecast area today. What a great way to end the week. If you have time, spend a little time outside in the middle of your work day. Or better yet, take off early for a hike or walk. Don't be surprised …
