Marine Weather and Tide Forecast for Tall Timber, CO

DISCUSSION /Through Sunday/
Issued at 155 PM MST Sun Nov 9 2025

Models show the northerly flow aloft tonight to gradually weaken and become northwesterly by Monday afternoon as upper riding moves slowly eastward towards Colorado. The northwesterly flow aloft is expected to continue through Tuesday night at jet level speeds of 30 to 50 mph. By Wednesday, the upper ridge is over the CWA and the zonal flow aloft is progged to increase in speed.

The QG fields point to very weak or no synoptic scale energy over the CWA tonight through Wednesday night. The QPF fields show no measurable precipitation through Wednesday night either. Will keep the dry weather going through Wednesday.

For temperatures, thickness fields point to daily highs getting 10 to 15 degrees F above normal much of the week. There is an outside chance of a record high or two being set through Thursday.

There will be elevated fire weather conditions; mainly Tuesday afternoon, across the plains due to the warmth, dryness and fairly breezy winds that are expected.

For the later days, Thursday through Sunday, zonal flow aloft on Thursday increases and becomes southwesterly by Friday ahead of an approaching upper trough. The trough axis is over the western Colorado border 00Z Saturday, then it moves across the CWA through mid day Saturday. The GFS is stronger than the ECMWF with this feature. This system will bring a chance of precipitation to the CWA Friday into early Sunday, especially in the mountains. Strong north-northwesterly flow aloft moves in early Sunday but then decreases through the day.
