Valley Forecast Check · Week 2 · Oct. 22–28
After today’s storms, all four Phoenix TV stations see a dry, sunny stretch, with highs near 80 this weekend and mid-80s early next week. The big split is Thursday: ABC15 and 12News give it a 70–80% chance of rain, while Arizona’s Family says 19%. And Arizona’s Family and FOX 10 posted the exact same high for all seven days.
This week’s check was pulled midweek (Wednesday, Oct. 21), so the scorecard covers Sunday through Tuesday only. Next week it’s back to a full week.

This week’s rain chances
Rain chance: the odds that any one spot gets at least 0.01 inch. FOX 10 shows icons, not percentages, so we list its icon as a word. The average uses the three stations with percentages.

How right were they?
We checked last week’s forecasts (pulled Saturday, Oct. 17) against what actually happened at Sky Harbor, Sunday through Tuesday. The National Weather Service recorded highs of 84, 91 and 93, and no rain.
Closest this week: FOX 10. Every station guessed too cool on Monday and Tuesday. Forecasts said 87 to 90; Sky Harbor hit 91 and 93.
Why does it say cloudy when it’s raining?
A forecast icon shows the main weather for the whole day, not every hour. A “40% chance of rain” means about a 4-in-10 chance that any one spot gets at least a little rain (0.01 inch). It doesn’t mean rain for 40% of the day. The Valley is huge, so a storm can soak one neighborhood while Sky Harbor stays dry, and the forecast was still “right.” That’s also why a 40% day that stays dry isn’t a miss.
Why are the numbers so similar?
When stations match almost to the degree, they’re probably starting from the same computer forecast data and adjusting a little. This week Arizona’s Family and FOX 10 matched on all seven highs. We don’t know for sure, so if you work at one of these stations, tell us how you build your forecast.

Heads up: this is real money, and you can lose what you put in. Arizona’s attorney general has fought Kalshi in court. A federal judge has blocked the state from prosecuting it, but after an August 2026 appeals ruling went against Kalshi in a Nevada case, Arizona asked to lift that block. As of Oct. 21, 2026, the block still stands. Postmarq isn’t paid for this link.
