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. Instead, brief but powerful storms roll through, often leaving behind cooler temperatures and stunning sunsets.&nbsp;Safety Tips During the Rainy Season&nbsp;<ol><li>Check the forecast daily: Download the WeatherNation app for frequent updates.&nbsp;</li></ol><ol start="2"><li>Be cautious on roads: Rain can make roads slick (Google 'Florida Black Ice') and cause flash flooding in low-lying areas.&nbsp;</li></ol><ol start="3"><li>Avoid open water and outdoor activities during storms: Lightning is a serious threat in Florida, often referred to as the lightning capital of the U.S.&nbsp;</li></ol><ol start="4"><li>Have a hurricane plan: June through November is also hurricane season, and some rainstorms can be part of larger systems.&nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/05/TRT 22 Hurricane Prep Week Sizzle with Michael Brennan-1746706747636.mp4" controls="true" width="100%"></video></li></ol>Tonight - MondayThe Storm Prediction Center has put Florida in a Slight Risk for severe storms.

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.

[<a href="https://cpo.noaa.gov/News/News-Article/ArtMID/6226/ArticleID/1685/Lack-of-Moisture-Connected-to-Drought-Propagation-in-North-America" target="_blank" rel="noopener">NOAA</a>] Droughts have disastrous impacts on the agricultural, economic, and public health sectors. With the formation of droughts still being researched, scientists ability to forecast droughts for North America has been greatly affected. <a href="https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2019GL082475" target="_blank" rel="noopener">In a new research paper</a>, Julio E. Herrera‐Estrada and co-authors used reanalysis data from 1980-2016 in combination with a moisture-tracking model to identify the effects that reduced moisture transport has in drought formation and dissemination in North America.

<img class="alignnone size-full wp-image-88125" src="https://media.weathernationtv.com/app/uploads/2018/02/midwestfarmlanddrought_noaa.png" alt="" width="650" height="375" />

They found that a decrease in moisture transport upwind resulted in more droughts across the United States. Also, they found that due to a lack of moisture exports, agricultural droughts upwind caused significant droughts downwind. In particular, the decreased moisture transport from land areas accounted for 62% of the precipitation deficiency in the high-profile Midwest drought of 2012.

<img class="alignnone size-full wp-image-109129" src="https://media.weathernationtv.com/app/uploads/2019/06/600600p6226EDNmainimg-2019-05-06.jpg" alt="" width="512" height="330" />

Furthermore, a decline in recycled moisture within a region corresponded to a decrease of transported moisture to that region. These results suggest that land‐surface may contain useful information for drought prediction, and highlight the importance of sustainable land‐use and of regional cooperation for drought risk management.
