12/12 12pm Update: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – December...

We have temperatures a touch above normal through Friday - and dry. Our next storm system begins to dump a prolonged period of snow on the mountains starting today (Thursday) but snow doesn't begin to fall until later Friday night. We'll see a snowy weekend (Saturday and Sunday) but with only moderate accumulation. Next week starts very cold - the thaw will be delayed.

Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – December 10-11, 2019

After 15 snow flakes fell in town this afternoon (Monday) we enter a very normal, dry (boring) stretch of weather. The models are in a lot of disagreement over what will come next; the weatherunderground and GEM models drop good snow on Longmont Saturday into Sunday. The GFS and NAM do not.

Update 12/8 8am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – December...

We have a cool down from a mild Saturday (that might not be as warm as expected if the high clouds stay in place and keep the cold air at the surface from mixing out) on to a chilly Monday. A storm system arrives Sunday into Monday putting fresh snow down in the mountains, but little moisture and warm temperatures (again) will keep us snow-less and possibly dry. Next week looks seasonably normal with no storms on the horizon.

Update 9:30pm 10/6 Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – December...

Our next storm is moving in with temperatures just at freezing at storm start rising to 40F during the height of the precipitation. Again, not a good recipe for a snow storm. Snow (and rain) could start as early as 6am, but will really get underway from 9am to 5pm. We have dry weather and warming temperatures through Saturday then another weather-fly my get in our ointment.

Another (deep southwest) storm will effect Colorado Thursday, but don't look for much snow from it in town. We get pretty warm for the weekend (relatively speaking) and sink into the ice box for most of next week.

Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – December 2-3, 2019

The next 10 days will see slightly cooler weather than normal and (at this point) a minor chance of rain/snow early Thursday morning. Quiet weather is back for a slow melt.

12/1 8:30am Update: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – Nov...

Happy Thanksgiving everyone! It will remain below freezing today with partly cloudy skies and no new snow (but a foot is sitting around). The mountains get another big snow hit tomorrow but we may see nothing to **maybe** an inch. The big news is very strong winds blasting the state for 12-18 hours on Saturday. This will blow snow around and create hazardous ground conditions, difficulty driving, snow drifts etc. Beyond that we go to the 40'sF for highs and enjoy a boring week with a very slow melt.

Update 11/27 11am: Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – November...

Impressive snow has and is still falling. Longmont has a foot as a base with snow ending around 12-2pm today (Tuesday). We remain cold and snow-free until the western counties get their snow on Friday. We may see 1-3 inches along I-25 (but who will notice it?).

Delayed Start For Several City Facilities Tuesday Due To Weather

Rec Centers, Youth and Senior Centers, and Longmont Museum will open at 10am. Due...

Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – November 26, 2019

A major winter storm dropping feet of snow in places along I-25 and the Foothills will begin to impact the area by mid-afternoon with rapidly deteriorating road and travel conditions by evening. A winter storm warning is in place and blizzard warnings will probably be issued for areas just east of us later today. Skies clear Tuesday afternoon with windy conditions. Thanksgiving looks dry and cold (and white). A small snow storm will re-coat the snow Friday before a dry and cold weekend.
