DISCUSSION
Issued at 103 PM MDT Thu Oct 15 2026
High pressure remains in place through the weekend with temperatures continuing to warm to around or slightly above normal. Saturday looks to be the warmest with afternoon highs rising into the mid 60s for many. Dry conditions remain in place through the weekend into the beginning of the work week. Beginning early next week, an upper low drops south along the west coast. Increasing southerly flow looks to bring moisture north into East Idaho by Tuesday, possibly as early as late Monday for some. The southerly flow MAY be able to enhance precipitation into portions of the central mountains late Tuesday into Wednesday. Ensemble means dig the upper low south into southern Nevada in a split flow pattern through late Wednesday, then slowly weakens and ejects the trough northeast through the remainder of the week. Clusters tell a much different story with significant differences in treatment of the split low. NBM appears to split the difference, keeping East Idaho unsettled and cool for the remainder of the week.

FIRE WEATHER
Issued at 158 AM MDT Thu Oct 15 2026
High pressure will be in control of our forecast for the rest of this week and through the weekend. Highs will continue to gradually warm with most returning to the mid 60s by Saturday afternoon. Dry conditions across the area mean min RHs drop to 15-25 percent in the Central Mountains on Friday, which looks to be the driest day of the next several. It's not until next week that we see highs drop back into the 50s and precipitation chances return to the forecast.
