DISCUSSION

Precipitation has finally come to an end across eastern Idaho. The area of low pressure that impacted us the last few days is over southeast Utah. This low continues to weaken and move eastward today with high pressure building in from the west over southeast Idaho.

There are some lingering clouds across our eastern areas currently but most areas have cleared out. With high pressure, clear skies, and lingering moisture expect patchy fog tomorrow morning. Expect dry conditions through Monday with a gradual warming trend under high pressure. Winds will remain light through Sunday. For lower elevations, highs today will be in the 50s for most and we return to the low 60s for Friday afternoon. Expect mid 60s by Sunday and Monday.

Overall, the models are showing a system starting to move into the area by early next Tuesday. Though, models continue to disagree on exact timing. Some models hold off the system until later next week. If models stay on the same track, expect winds to pick up by Monday afternoon. Currently models show good precipitation chances Tuesday and Wednesday. Currently, overall accumulation looks light to moderate, 0.10 to 0.25 for valleys and 0.25 to 0.5 for mountains.

Leftover CIGs from the previous days' storm will evaporate this evening with the continued eastward progression of that storm. No precipitation expected from these remmants. SKC should develop everywhere tonight, with the no-observations KDIJ and KPIH being the last at around 15/05Z. Weak pressure gradient allows downslope-downvalley wind to develop at KBYI, KPIH, and KIDA. KSUN also has its usual NNW wind for the overnight hours. KDIJ is the only question mark, but windspeeds never get more than 8KT. Light wind and unrestricted VSBY and sky condition continues well beyond the 16/00Z end time for the forecasts.

FIRE WEATHER

Issued at 1158 AM MDT Wed Oct 14 2026

High pressure continues to build into East Idaho through the weekend. Dry conditions with a gradual warming trend are forecast. Afternoon highs look to increase back to the mid to lower to mid 60s by Sunday for most lower elevations. There is potential for the next system to arrive as early as Tuesday, bringing the next round of light rain and high elevation snow to East Idaho.
