Jackson Hole weather this week

Just your ID

Jackson Hole scores 8.2 out of 10 and has no genuinely clear day in the next 16.

8.2/10

No clear day

0 genuinely clear days, 0 partly cloudy, 3 overcast, 1 wet, 0 stormy — out of 16 forecast days.

Bright days 0 vs dull days 4. Dull wins, so we do not call this a good week.

We are not showing a flattering tier word here. Why the score and the sky can disagree.

The model gives this week 8.2 out of 10 because it is warm and largely rain-free, and those are the two things the score measures. It is not measuring sunshine. With 0 genuinely clear days and 4 dull ones, expect grey skies. We are showing you the number and the contradiction rather than only the number.

4-day window, 0.5% rain-affected — Warm, dry, and the sun never shows — zero clear days in 4, one rainy day

How this week got its score

4 forecast days: 0 clear/mainly clear, 0 partly cloudy, 3 overcast, 1 wet (fog/drizzle/rain/showers), 0 stormy.
Trimmed mean of day scores 8.1 × 0.55 = 4.44
Worst day drag: worst day is 7.0 × 0.25 = 1.75 - one bad day cannot be averaged away.
Longest consecutive run of good days (≥7.0) is 4/4 = 100% coverage × 0.20 = 2.00
Best single day is 8.5 but it only counts through the trimmed mean - a lone great day cannot carry the window.

The full model, including why a single great day cannot rescue a bad week, is on the methodology page.
