After weeks of hot and mostly dry weather, the Southwest is beginning its transition into the annual North American Monsoon Season. A shift in the overall weather pattern is allowing deeper moisture to move north from the Pacific and Gulf, setting the stage for a daily chance of showers and thunderstorms across parts of Arizona, New Mexico, southern Utah, southern Colorado, and Nevada.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 061205-1783858333542.jpg">The North American monsoon is a seasonal wind shift that occurs each summer, transporting moisture from the eastern Pacific Ocean and Gulf of California into the Desert Southwest. As the moist air combines with intense daytime heating and mountainous terrain, thunderstorms become much more common during the afternoon and evening hours.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-11 074047-1783777256375.png">The first surge of monsoonal moisture is expected to increase storm coverage through the coming days. While many of these storms will produce beneficial rainfall for areas experiencing drought, they will also be capable of dropping heavy rain over a short period of time. Because the Southwest’s dry soils do not absorb water efficiently, runoff can develop quickly, creating a heightened risk of flash flooding in washes, slot canyons and other low-lying locations.<video src="https://media.weathernationtv.com/app/uploads/2026/07/2026-07-12 06-14-51-1783858518113.mp4" controls="true" width="100%"></video>Recently burned areas will be particularly susceptible to flooding and debris flows. Vegetation lost to wildfires leaves hillsides unable to absorb rainfall, allowing water, mud, and rocks to move rapidly downhill during intense thunderstorms.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 061320-1783858409508.jpg">The arrival of the monsoon may provide some relief from the persistent heat that has gripped the region in recent weeks. Increased cloud cover and scattered thunderstorms can help lower daytime temperatures, although conditions will remain warm and humid compared to the typically dry desert climate.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 061401-1783858450467.jpg">As the monsoon continues to strengthen through July, residents and visitors across the Southwest should be prepared for rapidly changing weather conditions each afternoon. Even storms that last only a short time can produce dangerous flash flooding, making it important to avoid flooded roadways and never enter fast-moving water.

Monsoon Moisture Returns to the Southwest, Increasing Storm and Flash Flood Potential

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

Life-threatening flash flooding developed overnight Thursday into Friday in Missouri to the SSW of St. Louis. Parts of Iron and Reynolds counties recorded upwards of 6-12 inches of rain, leading to water surging into homes and businesses. This resulted in numerous water rescues by emergency personnel, over 90 in fact, but the great news is everyone has been accounted for!<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2075552085597429997" src="https://x.com/WeatherNation/status/2075552085597429997"></div> With all of that heavy rain, the rivers rose very quickly leading to catastrophic river flooding like the Black River. In Annapolis, MO, the Black River crested at a new record high of 28.73 feet on Friday.<img src="https://media.weathernationtv.com/app/uploads/2026/07/PIC 3-1783811279974.jpg"><video src="https://media.weathernationtv.com/app/uploads/2026/07/VO_071026_RNC_LESTERVILLE,MO_INSANE VIDEO OF OF CATASTROPHIC FLOODING IN LESTERVILLE_FB_MS_E071026-1783735634947.mp4" controls="true" width="100%"></video><h1>Forecast</h1>Heavy rain and storms will continue to slowly follow the frontal boundary south through Sunday into early next week.

Extreme heat will get worse across the West this weekend, expanding into the Plains and Upper-Midwest through next week. Record highs fell on Saturday across parts of Wyoming and Montana with cities topping out over 100 degrees. Some of these forecast highs for cities like Billings, Montana could close to beating their all-time record highs. The all-time record in Billings is 108°, but it looks like it may be even warmer than that by Sunday afternoon.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 053147-1783855914393.jpg">Extreme heat watches, warnings, and advisories have been issued from Utah and Colorado into the Great Lakes.<img src="https://media.weathernationtv.com/app/uploads/2026/07/PIC 2-1783811581349.jpg">Heat safety will be a key concern going forward. Be sure to stay hydrated and keep looking in the back seat before locking the car. The heat will spike sharply on Sunday in the Central and Northern Rockies before temperatures slowly drop.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 053216-1783855941818.jpg">Extreme Heat Warnings cover parts of Utah, Colorado, and the Grand Canyon/Colorado River region in northern Arizona.<img src="https://media.weathernationtv.com/app/uploads/2026/07/PIC 2-1783811651778.jpg"><img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 054342-1783856632172.jpg">All time records could be broken in the Central Rockies as well. Salt Lake City has reached 107° fives times before in the past. They have a chance to do that again on Sunday. If they surpass 107, it would be a new all-time record.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-12 054403-1783856652680.jpg">Long-term models suggest this might be something to get used to, however. This ridge looks to linger in the area and could strengthen by next weekend. The Climate Prediction Center is highlighting much of the West with above-average temperatures into the middle of July.<img src="https://media.weathernationtv.com/app/uploads/2026/07/Screenshot 2026-07-07 161953-1783462799142.png">Here are a few heat safety tips for people affected by the heat.<img src="https://media.weathernationtv.com/app/uploads/2026/07/pic5-1783634512392.png">
