DISCUSSION

Issued at 212 AM MDT Wed Oct 14 2026

For the most part, precipitation has finally come to an end across Eastern Idaho as our area of low pressure continues to move eastward today. Clouds are also going to continue clearing out and we are watching for fog development in the Snake River Plain this morning, but we do also have enough of a lingering cloud deck that we may avoid the fog. We will see how it plays out over the next few hours. If we can clear out and stay clear, temperatures are expected to drop into the 20s across much of the area, so a Freeze Warning remains in effect through the morning hours. If we can hit a widespread hard freeze, this will likely be the last frost/freeze product of the season.

As this low departs our area, high pressure begins to slowly build in over the West and we will get a warming trend underway and stay dry for the next several days. Highs today will be in the 50s for most and we return to the 60s for Thursday afternoon. By Friday afternoon and through the weekend, more of us will be making our way towards and into the low 70s. We stay dry through the weekend, too, so it should be a good fall weekend to get out and enjoy. There is potential for another system to impact us next week, but there is no model agreement yet on it for timing or precipitation, though it seems likely to cool us off.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 533 AM MDT Wed Oct 14 2026

High pressure is building in over Eastern Idaho today and for most of our sites, that means dry, VFR conditions. However, as we've cleared out cloud cover we have some pockets of fog and low clouds at PIH and DIJ. Low CIGs and VIS have brought IFR and LIFR conditions at these two sites and will continue to do so on and off for the early morning. This lower cloud deck and patchy fog is near IDA, but remaining outside the terminal for now, and we will continue to watch it for the next few hours and adjust if needed. Conditions will improve later in the morning with VFR conditions expected at all sites this afternoon.

FIRE WEATHER

Issued at 212 AM MDT Wed Oct 14 2026

As the area of low pressure that has brought us so much moisture over the last several days moves eastward, isolated showers will linger this morning in the southeastern corner of Fire Weather Zone 413. Elsewhere, we are dry and will stay dry through the rest of the week and the weekend as high pressure builds back in over the area. Temperatures will be on a gradual warming trend with highs in the 50s for most today before returning to the 60s for Thursday and Friday. Through the weekend, highs reach the low 70s for parts of the eastern Magic Valley and lower Snake River Plain.

PIH WATCHES/WARNINGS/ADVISORIES
