Nice Weather Today: Four Corners Shines, San Diego Backcountry Wins the Week
Farmington and Chinle top today's map, Fargo gets a near-perfect Sunday, and San Diego's inland backcountry towns quietly run a 7-day Nice-or-better streak.
Today's Best Air Sits Over the Four Corners, But the Real Story This Week Is San Diego's Backcountry
Good Saturday morning, y'all. Today's map has an obvious headline, and it's sitting right where the Four Corners meet.
The Ceiling Today: Farmington, Gallup, and the High Desert
Farmington and Gallup, NM, along with Kayenta and Chinle, AZ, and Blanding, UT, are running the day's best weather anywhere in the country. A flattening upper ridge and genuinely dry air have this zone at a Beautiful score of 85.1, with highs near 86°F, lows near 58°F, and dewpoints around 53°F. Cloud cover is a sparse 24 percent, rain chances sit at 4 percent, and the air is clean, with AQI near 45. Chinle is the standout city at a 92 score thanks to lighter 11 mph wind and a slightly more comfortable dewpoint.
Perfect is technically on the table for Day 1, but nothing actually clears it. The UV index runs 7.5 in this zone, just over the 7 threshold Perfect requires, and that hard gate holds even a genuinely gorgeous day at Beautiful. If you're hiking around Farmington or the Chinle area today, that's a small thing to plan around: strong sun, so bring the hat and the water, but otherwise this is about as good as a September day in the high desert gets.
Most of the rest of the country isn't nearly this lucky today. The central Plains and Midwest are stuck at Fair to Decent, dragged down by 13 to 15 mph wind and cloud cover running 50 to 77 percent, even with genuinely mild temperatures. That's the tradeoff pattern all weekend: pleasant numbers on paper, but wind and clouds keeping the feel a notch below what the thermometer promises.
Sunday's Reward: A Fall Preview in Fargo, and a Rougher Day for NFL Tailgates
Behind tomorrow's departing cold front, Fargo and Grand Forks, ND, along with Bemidji, Devils Lake, and Roseau, MN, land in a tight, comfortable band at 92.0. Highs run around 61 to 66°F with dewpoints near 40°F, wind averaging a light 9.2 mph, and rain practically absent at 1 percent. Air quality is excellent at AQI 31.
This zone comes within a tenth of a point of Perfect on the raw score, which is a little funny once you look at why it doesn't get there. Both the temperature and dewpoint sub-scores fall just under the 92 threshold Perfect requires, and they fall short specifically because the air is too comfortable to be warm enough. Cool, dry, and calm is exactly what you want for a Sunday walk or a farmers market run in the northern Plains, it just isn't going to score as "hot enough" in the framework.
Meanwhile, if you're tailgating for an NFL Sunday game, check your city first. Philadelphia, Jacksonville, and the broader Ohio Valley and Mid-Atlantic corridor are dealing with a slight risk of excessive rainfall and marginal severe potential per WPC, tied to a warm front lifting moisture north along the I-95 corridor. Cincinnati, Nashville, Pittsburgh, and Charlotte's 1 p.m. kickoffs sit closer to Fair territory than Nice, with humidity and cloud cover doing the limiting. The good outdoor seats this weekend are in Fargo, not most NFL stadiums.
The Week's Real Headline: San Diego's Backcountry Won't Quit
Here's the pattern that's easy to miss if you only look at one day at a time. Pull the full week of data and the towns dominating the rankings aren't the beach cities you'd expect. They're San Diego County's inland backcountry communities.
Campo (mean score 84.7), Pine Valley (84.6), and Potrero (84.6) top the entire week's rankings, each logging Nice-or-better conditions all seven days, with their best day (Sunday, Day 2) hitting a 92.0 score. Temecula, Etna, Descanso, Fallbrook, Alpine, Jamul, Harbison Canyon, and a long list of East County communities, Spring Valley, Rancho San Diego, Valley Center, Bonsall, Julian, El Cajon, are right behind them, most also running a perfect 7-for-7 week at Nice or better, many peaking around 82.0 on Wednesday (Day 6).
Compare that to the coastal cities that usually get the headlines. San Diego proper and Los Angeles both show up in the top 10 on most days this week, but their scores consistently trail the backcountry towns, and the discussions are blunt about why: air quality, not temperature or rain, is the ceiling. Day 2's write-up puts it plainly, San Diego's effective AQI of 52 sits just above the cutoff for the next tier up, even though every other comfort ingredient, dewpoint, precipitation, wind, already clears it. The backcountry towns, tucked into the hills and mountains away from the coastal haze, simply don't run into that same wall as often.
If you're planning a week of trail time, patio dinners, or weekend errands in San Diego County, this is genuinely useful: skip the marine layer debate on the coast and head inland toward Julian, Alpine, or the Descanso area instead. You can check the current lineup any day on the Nice Weather outlook page.
A Bonus Beautiful Stretch: Monday in the Pacific Northwest and Northern California
One more day worth flagging before it arrives. On Monday, the ceiling shifts to the Pacific Northwest and far northern California, where Portland, Salem, Eugene, Bend, and Medford, OR all reach Beautiful, with Salem, Bend, and Medford scoring 92.0. Etna, in far northern California near the Oregon border, actually posts its own best day of the week on Monday for the same reason, it sits right at the edge of this same clean, dry airmass.
Wind runs a gentle 7 mph with gusts to just 9.6 mph, cloud cover is down to 7 percent, and dewpoints hover near 43°F. It's a genuinely great day for hiking, cycling, or sightseeing across the Willamette Valley and southern Oregon high country. The one caveat worth carrying with you: dry vegetation and low humidity are keeping fire danger elevated even as the recreational weather shines, so if you're camping, be careful with anything that throws a spark.
What to Watch Behind the Nice Stretch
A couple of things worth keeping in the back of your mind heading into next week. CPC's week-2 outlook flags a slight risk of heavy precipitation and possible flooding returning to the Four Corners region by September 19-23, the same high desert that's shining today. And in the Southeast and Gulf Coast, tropical humidity keeps creeping into the Decent and Fair tiers through the extended range, with Atlanta and Jacksonville both showing up as the drag cities in the Day 4-7 discussion thanks to dewpoints in the upper 60s. None of that changes the picture for the next few days, but it's a reminder that this dry, comfortable stretch out west has an expiration date.
For now, though, the map is generous. Whether you're chasing high desert sunshine in the Four Corners today, a crisp fall preview in Fargo tomorrow, or you just live somewhere in San Diego's East County and haven't checked the forecast all week, you're sitting in a good spot.
