DISCUSSION

Issued at 1248 AM MST Tue Nov 3 2026

Precipitation has ended across the area, with winds finally subsiding over northern Johnson County. Skies remain overcast over much of the CWA early this morning, with clear skies over southwestern portions of the state. Low clouds/fog will be possible at times through the rest of the morning, with many locations having cloud heights drop below 1000ft at times already. There is not a strong signal for fog with low visibilities at any particular area, but will continue on eye on any developing trends. Skies will quickly scatter out by 18Z, with mostly clear skies across areas east of the Divide.

There are not many changes with the forecast from the previous discussion. Conditions are expected to remain dry through the rest of the week, as an area of high pressure settles over MT today. Temperatures will stay at or slightly below normal through the week with winds staying light. The high center will also keep a weak Pacific system to the south over UT/CO Wednesday, with the main impact being mainly in the form of cloudy skies over southern/southwestern portions. Isolated showers will be possible over the western half of Sweetwater County and southern Lincoln County from the northern end of this low pressure system.

The pattern then briefly becomes more active by Thursday as a trough moves over the Northern Rockies and pushes the high center over the Northern Plains. The chance for high winds in northern Johnson County no longer looks likely as models have now trended toward a ridge building over the Great Basin and Northern Rockies, keeping the PFJ further north away from the region. Temperatures will trend above normal Sunday and Monday as the aforementioned ridge shifts more over the Northern Rockies and Alberta/Saskatchewan.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 945 PM MST Mon Nov 2 2026

Mainly VFR conditions, except for KRKS, with some light rain and MVFR ceilings ongoing for the first hour or two to start the period. Otherwise, VFR thereafter with a limited coverage of possible IFR conditions with fog/stratus at KBPI/KPNA and LIFR at KJAC between 11-14Z. However, confidence low with the ongoing mid level ceilings across much of the CWA limiting development but carrying TEMPO groups with these limiting visibilities but scattered low stratus. Clouds finally do start to clear west to east as high pressure builds in, scattering and lifting out after 14-18Z and into the afternoon hours for the remainder of the period. Light winds throughout, 10kts or less, at all locations with no other weather elements at this time.
