While much of the western U.S. is feeling record-breaking heat over the weekend, a big change to the weather pattern is expected as we head into next week. As this transition occurs, Montana will see rounds of thunderstorms, with some severe potential.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-10 183309-1746923595438.png">With temperatures pushing 90°F across Big Sky Country, sufficient instability will be available for thunderstorms to develop and strengthen. These storms could organize underneath strong upper-level winds. The upper-level dynamics are ahead of a significant trough that will ultimately impact the rest of the country in the days ahead.<video src="https://media.weathernationtv.com/app/uploads/2025/05/nwfun-1746923732052.mp4" controls="true" width="100%"></video>While the northern Rockies will be looking at thunderstorms this weekend, the main core of the upper-low will move onshore by Monday morning, beginning the transition to a cooler and wetter pattern.<video src="https://media.weathernationtv.com/app/uploads/2025/05/ddddddssss-1746932648342.mp4" controls="true" width="100%"></video>By the middle of next week, expect a significant cooldown along with widespread precipitation accumulation across the western half of the country. In fact, many of our mountains across the West could see significant snow!<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-10 183723-1746923854605.png"><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-10 183809-1746923897591.png">We'll continue to update this developing story as more details come into focus here on WeatherNation!

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.

Florida can not seem to shake the storms over the last few days! Since last Monday, there have been stormy conditions, even bringing some small hail across the Sunshine State. More rain is forecast as a frontal boundary continues to stall. <img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-10 182854-1746923341782.png">Florida is famous for its sunshine, but at the end of spring, the skies often tell a different story. Each year, Florida’s rainy season brings afternoon downpours, rumbling thunderstorms, and the occasional flash flood. Understanding this seasonal shift is especially important to visitors due to how energetic these storms can be&nbsp;(Hello, lightning).Over the following days, any thunderstorm could drop some hail or damaging winds. Flooding rainfall is also possible as multiple inches of rain could swamp some roadways and low-lying areas.So, When Is Florida’s Rainy Season Usually?&nbsp;Florida’s rainy season typically runs from late May through mid-October, aligning closely with the Atlantic hurricane season. During this time, the state receives nearly 70% of its annual rainfall (Goodbye drought), with frequent storms developing in the early afternoon and clearing by evening.<img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746760892920.png">&nbsp;The pattern is driven by a combination of high humidity, warm temperatures, and prevailing sea breezes that converge inland, lifting moist air high into the atmosphere where it condenses into rain-producing clouds.&nbsp;What to Expect Daily&nbsp;Afternoon thunderstorms are the hallmark of Florida summers. These storms are usually short-lived but intense, capable of producing heavy rainfall, lightning, and gusty winds. It is common to see sunshine in the morning, followed by a dramatic downpour after 2 PM.&nbsp;Despite the daily rain, most of Florida’s rainy season does not consist of day-long washouts.

A break in storms for the Northeast is on the way this Sunday, but first, another round of heavy showers is expected. This follows heavy rain earlier in the week, leaving soils saturated and primed for additional flooding.<img src="https://media.weathernationtv.com/app/uploads/2025/05/through ffo-1746911006647.png">A few showers linger in Maine, and everything clears out as the low moves east.

Looking at the rain from a glass half full lens, the Four Corners has received beneficial rain and snow over the last several days. Rain and Snow totals have already started piling in for Colorado. In the past 24 hours the highest totals for rain have been over 2.50 inches for Rye and Denver has seen over an inch of rainfall. <img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-07 053642-1746617812907.png">The rain is not the only factor. So far, Colorado has seen over half a foot of snow, and totals will be on the rise Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-07 053705-1746617844560.png">Clouds and rain will linger through mid-morning before another round of rain will move through in the afternoon. This slow moving storm system will also deliver a big cool-down. The temperature will drop by 10-20 degrees (or more). The heaviest snow across the Colorado Rockies will continue through Wednesday for elevations 8000 ft+, along with heavy rainfall in the foothills, front range, and plains.<video src="https://media.weathernationtv.com/app/uploads/2025/05/2025-05-07 05-40-05-1746618046345.mp4" controls="true" width="100%"></video>This event could bring in some much-needed snow for the higher terrains to keep the ski resorts open a little while longer across parts of the Rockies. Snow totals will likely reach 2' in the high peaks of the Colorado Rockies. Pikes Peak under a Winter Storm Warning with up to 4 feet by early Wednesday. Late-season winter storms can pose a significant risk to hikers and outdoor recreationists unprepared for winter conditions.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-07 053756-1746617906825.png">The soaking rain is another issue, as well. Some areas will be picking up 1-3 inches of rain along the I-25 corridor. Parts of southeastern CO could see isolated flooding with these showers. The mountains will keep afternoon shower chances throughout the weekend, while the rest of the areas will start to dry out.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-07 053803-1746617915680.png">After Wednesday, temperatures will start to warm back up. The area will dry out as a ridge of high pressure moves in. By the end of the week areas in the Four Corners can see temperatures 80 degrees and higher with plenty of sunshine.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-07 053931-1746617979062.png">Stay with WeatherNation for the latest.

Major Spring Storm Continues With Rain & Snow For the Rockies

Fall and winter become Santa Ana season for southern California. It looks like 2018 will end and 2019 will begin with a round of the signature dry, gusty, fire danger inducing winds.

Santa Ana winds are offshore, or northeasterly, winds that descend in elevation in southern California. High pressure over the Great Basin sets up the pattern. As the winds get closer to sea level, they speed up, warm the air and dry things out. This often greatly increases the risk of wildfires.

<img class="alignnone size-full wp-image-101736" src="https://media.weathernationtv.com/app/uploads/2018/12/LA-Santa-Ana-Expl.jpg" alt="" width="1920" height="1080" /> <img class="alignnone size-full wp-image-101737" src="https://media.weathernationtv.com/app/uploads/2018/12/LA-Santa-Ana-Set-Up.jpg" alt="" width="1920" height="1080" />

Monday December 31 will bring a Santa Ana set up back to the region. NWS Los Angeles highlights the timing for the strongest winds in their forecast discussion:
"The strongest Santa Ana winds with this event are
expected to occur in the LA/Ventura county mountains (including
the Santa Monicas) where damaging gusts of 55 to 65 mph will be
possible which will likely require later shifts to issue a high
wind watch for these areas as we draw closer to the event. Wind
gusts of 35 to 55 mph will be possible across coastal and valley
areas with this upcoming event."
<img class="alignnone size-full wp-image-101739" src="https://media.weathernationtv.com/app/uploads/2018/12/LA-Mon-Noon.jpg" alt="" width="1920" height="1080" /> <img class="alignnone size-full wp-image-101738" src="https://media.weathernationtv.com/app/uploads/2018/12/LA-Tue-AM.jpg" alt="" width="1920" height="1080" />

Red Flag Warnings may also be issued for the tandem fire danger. You may remember the <a href="https://media.weathernationtv.com/news/top-10-events-of-2018/">incredibly costly and destructive wildfires</a> in southern California earlier this year that made our Top 10 events of 2018.

The addition of holiday festivities could make the strong winds potentially more damaging. Anyone headed to Pasadena for the Rose Parade will need to keep a close eye on the forecast through Tuesday.
