Significant travel weather for the next 2-3 days.

Weather Impacts Pacific:

— South-central Washington, including the Yakima Valley: Patchy dense fog this morning may reduce visibility to one-quarter mile or less. I-82, US-12 and US-97 may be affected.

— Northern California, including Redding, the northern Sacramento Valley, adjacent foothills, lower Sierra Nevada slopes and Coast Range: A Red Flag Warning continues until 5 p.m. North to northwest gusts of 20–35 mph and humidity of 10–20% will support rapid fire spread, with the strongest winds this morning. I-5, CA-36, CA-70, CA-99, CA-162 and CA-299 may be affected.

Weather Impacts Mountain:

— Central Montana, including Fergus County below 4,500 feet and the Snowy and Judith mountains: A High Wind Warning is in effect today. West winds of 30–40 mph with gusts to 60 mph will create hazardous crosswinds, including along US-87 and US-191.

— West-central and northwestern Wyoming, including the Absaroka Mountains, Cody Foothills and Upper Wind River Basin: High Wind Warnings continue today, with west winds of 30–40 mph, gusts to 60 mph and localized gusts to 75 mph in the Absarokas. Strong crosswinds and vehicle blow-over risk are possible on exposed routes including US-14, US-16, US-20, US-26, US-212 and US-287.

— South-central and southeastern Wyoming, including central Carbon County, the North Snowy Range foothills and central Laramie Range: A High Wind Watch covers portions of the area today. West winds of 25–40 mph with gusts near 60 mph may produce hazardous crosswinds along I-25, I-80, US-30 and US-287.

— Central, southern and eastern Wyoming: Red Flag Warnings are in effect from noon to 8 p.m. West to northwest winds of 20–40 mph, gusts of 45–60 mph and humidity of 10–20% will support rapid and potentially erratic fire spread. I-25, I-80 and numerous U.S. highways may be affected.

— Star Valley in west-central Wyoming: A Freeze Warning continues until 9 a.m., with temperatures of 26–30°F.

— Southwestern Colorado near Ouray and the Gold Mountain burn scar: A Flood Advisory continues early this morning. Thunderstorms have produced rainfall rates above 1 inch per hour, with flash flooding and debris flows possible near Cutler and Dexter creeks and along US-550.

— Southeastern Arizona, western New Mexico and nearby far southwestern Colorado: Heavy thunderstorms may produce flash flooding this afternoon and evening. The greatest excessive-rain risk is focused from southeastern Arizona into portions of western New Mexico, while surrounding flood risk extends into adjacent areas including far southwestern Colorado. Stronger Arizona storms may produce 1–2 inches of rain with isolated totals above 2 inches, flooding washes, burn scars, low-water crossings and other flood-prone terrain.

— Southeastern Arizona and portions of New Mexico Tuesday, then much of New Mexico and adjacent southeastern Arizona/far southwestern Colorado Wednesday: Repeated afternoon and evening thunderstorms will maintain a flash-flood threat. Wednesday may be the more active day, with localized 2–3 inch totals possible in western and northern New Mexico, including vulnerable burn scars. This wording intentionally keeps the day-by-day geography separate rather than applying one categorical risk level to the entire three-day footprint.

Weather Impacts Central:

— Much of North Dakota: A High Wind Warning and Wind Advisories are in effect today into early Tuesday. Western areas may see west winds of 30–40 mph with gusts to 55–60 mph this afternoon and evening; central and eastern areas may see gusts around 50 mph later today and tonight. I-94, US-2, US-52, US-83, US-85 and US-281 may be affected.

— Northern South Dakota: Wind Advisories cover much of northern South Dakota today into tonight. Northwestern areas may see gusts of 45–60 mph with blowing dust, reduced visibility and flying debris; gusts farther east may still make travel difficult for high-profile vehicles. US-12, US-83, US-85 and US-212 may be affected.

— West-central and northwestern Nebraska: A Red Flag Warning is in effect from noon to 8 p.m. West to northwest winds of 20–30 mph with gusts of 35–45 mph and humidity of 12–17% will favor rapid fire spread. US-20, US-26 and US-385 may be affected.

— A small portion of northeastern Kansas and northwestern Missouri: A Flash Flood Warning continues until 10:45 a.m. CDT. Between 2.5 and 4 inches of rain has already fallen, with another 1–2 inches possible. Flooding of highways, streets, underpasses and low-lying areas is likely; I-29 is affected.

— Eastern Nebraska, western and central Iowa, northern and western Kansas and far northwestern Missouri: Scattered strong to severe thunderstorms are possible late this afternoon and evening. The greatest severe-weather risk is centered on eastern Nebraska and western Iowa, where large to very large hail, damaging winds and isolated tornadoes are possible. I-29, I-35, I-70 and I-80 are among the major corridors potentially affected.

— Eastern Nebraska, south-central and southeastern Minnesota, central and southern Wisconsin, most of Iowa and far northwestern Missouri: Multiple rounds of thunderstorms may produce significant flash flooding tonight into early Tuesday. A Moderate Risk is focused on central and southern Iowa, where localized rainfall of 3–6 inches and scattered flash flooding are possible, including around Des Moines. I-29, I-35, I-39, I-41, I-43, I-80, I-90 and I-94 may be affected.

— Central Plains and Midwest Tuesday into Wednesday: The heavy-rain corridor shifts and expands across southeastern Nebraska, central and eastern Kansas, Iowa, northern Missouri, Illinois and southern Wisconsin. Training thunderstorms may produce 2–4 inches Tuesday evening near northeastern Kansas, southeastern Nebraska and northwestern Missouri, followed Wednesday by widespread 2–3 inch totals and localized amounts above 4 inches from eastern Nebraska into Iowa and surrounding Midwest areas.

— Eastern Kansas, northern Missouri and central/northern Illinois Tuesday: Scattered strong thunderstorms may produce isolated damaging wind gusts during the afternoon and evening. I-29, I-35, I-55, I-64, I-70, I-74, I-80, I-90 and I-94 may be affected.

— Southern Plains and Texas: Heat Advisories continue today. Eastern and southern Oklahoma, much of eastern, central and southern Texas, western and south-central Arkansas and northern Louisiana will see heat indices generally around 107–111°F, with localized values up to 114°F in the Coastal Bend and Lower Rio Grande Valley. I-2, I-69C, US-83 and US-281 are among the affected corridors.

— Lower Ohio and Tennessee valleys Tuesday and Wednesday: Heat indices near 105°F are expected across portions of southern Illinois, Indiana and Kentucky, with Middle Tennessee potentially reaching about 108°F and northern Alabama near 105°F.

— Lower Mississippi Valley and Mid-South: Heat Advisories cover portions of southeastern Kansas, Missouri, Arkansas, northern Louisiana, Mississippi, western Tennessee and southwestern Kentucky today and Tuesday, with heat indices generally 105–110°F. Southeastern Missouri and southwestern Kentucky may remain near 105°F into Wednesday.

Weather Impacts East:

— Southern Lower Michigan, northern Indiana and northwestern Ohio Tuesday: Isolated strong to severe thunderstorms may produce locally damaging wind gusts during the afternoon and evening. I-65, I-69, I-75, I-80 and I-90 are among the major corridors potentially affected.

— Northwestern Indiana Wednesday into early Thursday: Repeated heavy thunderstorms may produce flash flooding and disruptions on I-57, I-65, I-80, I-90 and nearby U.S. highways.

Tropical Weather Outlook for the next 7 days:

— Eastern Pacific: Tropical Storm Norbert, about 1,725 miles west of the southern tip of Baja California, has 40 mph winds and is moving west at 13 mph. Tropical Depression Fifteen-E, about 735 miles southwest of Baja California, has 35 mph winds and is moving west-southwest at 9 mph. Fifteen-E may briefly strengthen into a tropical storm today, while both systems should weaken during the next couple of days. Neither storm threatens the continental United States.

Extended Hazard Outlook

Confidence in the Extended Outlook:

Confidence is above average for the earlier period, with generally good agreement on the large-scale pattern, although uncertainty remains in how the western U.S. pattern evolves. Confidence decreases to average later in the outlook as solutions diverge and uncertainty increases around the evolving transitional pattern.
