Marine Weather and Tide Forecast for Raymer (New Raymer), CO

DISCUSSION /Through Tuesday/
Issued at 1231 PM MST Tue Feb 10 2026

Current water vapor imagery shows moisture embedded in zonal flow aloft. Light snow showers are ongoing across the Park Range and northern Front Range mountains, with a few scattered snow showers spilling onto the northern plains. Expect these showers to continue through this evening and tonight, with a couple of inches of accumulation for the high terrain. For the northern I-25 corridor and plains, snowfall is too light and temperatures are too warm for measurable accumulations this evening. However, there could be slick spots on the roads this evening as temperatures drop to near-or-slightly below freezing.

Flat upper level ridging returns on Wednesday through Friday, with southwest flow over the state as a trough off the coast of California digs south and travels east. Pacific moisture will trickle into the region on Wednesday, allowing for a prolonged and more widespread period of precipitation across the mountains through Friday. Relatively warm temperatures on Wednesday will keep snow levels around 8000 ft, which will result in a rain/snow mix for lower elevations in the mountains. Despite best forcing southwest of us, the development of a 700-mb jet and ample moisture availability will allow for enhanced snowfall on Wednesday. This is reflected by frontogenesis in hi-res models across our northern mountains. Areas in the Park Range could see snowfall accumulations between 6-15 inches, with greater amounts of around 20 inches at higher elevations. For the northern Front Range mountains, 4-10 inches with localized higher amounts are possible. For this reason, have decided to issue a Winter Storm Warning for the Park Range and a Winter Weather Advisory for the northern Front Range mountains Wednesday morning through Thursday morning. Opted out of any winter weather highlights for our southern mountains due to less favorable orographics. However, 2-6 inches is expected for areas along and south of the I-70 mountain corridor, with higher amounts possible at highest elevations.
Travel will be difficult to hazardous in the mountains, particularly in the morning and evening. Unfortunately, the plains are expected to stay dry on Wednesday, with the exception of a few light showers in the northern plains. Temperatures will be reaching up to the high 50s/low 60s.

Snow will gradually taper off in the mountains throughout the day Thursday, as flow aloft weakens with the eastward trek of the trough. Cold air will be advected into the region in the late afternoon, which will drop snow level to around 6000-6500 ft.
However, very light snow showers are expected by then, with only a few inches in additional accumulation.

Guidance has continued to struggle how to handle the evolution of the trough as it transforms into a closed low and treks east on Thursday, with the most recent model runs now trending towards a more southward track. With this change in track, precipitation potential and QPF amounts has decreased across the plains. This is reflected in a downward trend in QPF amounts on the GFS and ECMWF ensemble runs, with some solutions showing no QPF for much of the plains. With the expected warm temperatures, scattered light rain showers (potentially rain/snow mix at times) are possible across the plains late Thursday and into Friday. As of now, precipitation chances have decreased for Saturday. However, if the track of the low begins trending northward, confidence will increase for precipitation late Friday and into Saturday.

Upper level ridging returns this weekend, along with well above normal temperatures. Ensemble guidance has trended towards max temperatures in the high 50s to low 60s across much of the plains.
After that, another disturbance could bring mountain snow at the beginning of next week.

AVIATION /00Z TAFS through 00Z Thursday/
Issued at 502 PM MST Tue Feb 10 2026

VFR conditions expected throughout the TAF period. DEN will have easterly winds that will give way to southeast winds this evening. Around 05-06Z, drainage winds will develop at DEN and APA.

All terminals will have light and variable winds during the mid to late morning hours. A DCVZ will develop to the southeast of DEN and APA during the afternoon on Wednesday. This will likely shift winds to the northeast at BJC and DEN during the afternoon. Then, winds will shift to the northwest as the DCVZ intensifies. APA may continue to have a westerly component of the winds throughout the daylight hours. However, a brief period of light easterly winds may occur from time to time.

Otherwise, high level clouds will persist with some mid level clouds Wednesday afternoon.
