Key Messages
- A warming trend will continue through the week.
- Elevated to locally critical fire weather conditions will occur across central and southern Utah Tuesday.
- Moisture increases late in the weekend and into the weekend.
Discussion
...Mostly dry and hot conditions will continue for most of the upcoming week as the monsoon moisture tap remains cutoff given a broad ridge draped across the southern plains. Diurnal convection will remain isolated (<30% chance) each day with most of this staying confined to the terrain.
A weak shortwave will be passing through Montana on Tuesday. This will increase southwesterly flow across the region with afternoon gusts 20-25 mph, and a slight increase in PoPs across far northeastern Utah and southwestern Wyoming.
The ridge strengthens across the southwest later this week with highs in the mid to upper 90s across most valley locations on Thursday and Friday. This ridge will start to advect more moisture into the area through the weekend which will help to increase precipitation chances across most of the area with temperatures remaining warming than normal for this time of year.
Aviation
...KSLC...Predominantly VFR conditions will continue through the TAF period with FEW-SCT midlevel clouds. South winds will largely prevail through the night into Monday morning. Northwest winds are expected to return Monday afternoon between 19- 21z.
REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will prevail areawide through the valid TAF period. Isolated showers and thunderstorms are expected to develop Monday afternoon mainly over the higher terrain. Generally light winds with typical diurnal trends are expected at area terminals.
Fire Weather
, Issued 126 PM MDT Sun Aug 16 2026... Conditions will become gradually hotter and drier through Thursday, with a low chance of showers and thunderstorms developing on Monday and Tuesday afternoons. Chance for wetting rains remains near zero. Near critical to critical humidities will become more widespread across most valleys with most higher terrain seeing minimum RH in the 25-40% range. Southwesterly winds will increase slightly on Tuesday and Wednesday afternoons, resulting in widespread elevated fire weather conditions with isolated areas reaching critical values for wind and RH, primarily in valley locations where RH is lower.
Monsoonal moisture looks more likely to return by Friday, though isolated thunderstorms could develop across far southern Utah by Thursday afternoon. This monsoon push will likely result in increasing RH, wetting rain chances, and lightning probabilities.
