UPDATE

Issued at 1136 AM MST Tue Nov 3 2026

Quiet weather over the area today. A few areas of low clouds linger over western Wyoming, but continue to dissipate. Seasonal temperatures and light winds persist through the much of the week. A quick-moving system to the south tonight and into Wednesday brings increased clouds across the south, with some light rain showers from an Afton-Rock Springs line and south.

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 to keep an 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 /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1051 AM MST Tue Nov 3 2026

The low clouds across western terminals are expected to decrease over the next few hours. Otherwise, VFR conditions are expected today with mostly clear skies this afternoon. High clouds will increase this evening as they move in from the west, spreading east through Wednesday morning. These clouds and drier air at the surface are expected to keep fog impacts minimal for Wednesday morning.
