DISCUSSION

Issued at 149 AM MDT Sun Oct 18 2026

An area of low pressure over Southern California is moving northeast today, which is tempering our high pressure just a bit to keep us a few couple of degrees cooler this afternoon than yesterday. We'll still be a bit above our seasonal norms though, back into upper 60s and low 70s in the eastern Magic Valley and lower Snake River Plain. Winds remain fairly light today, making for another beautiful fall afternoon to wrap up the weekend.

To start the week, the upper level low that will bring us moisture eventually will be dropping south along the West Coast and our afternoon highs will still be in the 60s and low 70s with an increase in wind gusts to around 20 to 25 mph in the afternoon and evening. As that low continues to drop southward, we will see it pull a bit of moisture northward as early as Tuesday, but that precipiation chance continues to look like isolated activity, at best. That low makes its move eastward in the second half of the week as troughing moves into the PNW on Friday. The combo of this trough and low farther south will bring more widespread moisture and a temperature drop for Thursday and Friday. While exact numbers of how much precipitation we'll see is expected to vary greatly over the next few days, there is decent agreement on temperatures falling into the low and mid 60s on Thursday and 40s and 50s by Friday.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

VFR conditions continue once again today with some FEW mid and upper level clouds at times through the afternoon and evening. Winds remain light and variable for most of the day.

FIRE WEATHER

Issued at 149 AM MDT Sun Oct 18 2026

Today will be nearly a repeat of yesterday as far as temperatures, min RHs, and winds go across the area. Even Monday will have little to no forecast changes. On Tuesday, an isolated shower chance is introduced and will at least increase min RHs across the area. It's not until Thursday/Friday that we see bigger changes for the forecast as a low to our south brings Pacific moisture back to the area and troughing from the north brings in cooler temperatures. Expect a wet, cool end to next week.
