The National Hurricane Center upgraded the chance for tropical formation late Monday. There's now about a 40% chance in the next 48 hours of formation. This area is denoted the title AL93, or Invest 93L, since they're running the hurricane models on this area of low pressure. The development of tropical characteristics, however, may only matter in name alone.<video src="https://media.weathernationtv.com/app/uploads/2025/07/lklkhh-1752628482805.mp4" controls="true" width="100%"></video><h1>Forecast Models</h1>Since this is an area of investigation, there are forecast models, commonly referred to as spaghetti plots. According to the NHC, this system is forecast to move west across the Florida Peninsula on Tuesday before moving into the northeastern Gulf mid-week. Conditions remain favorable for additional development, and if it remains offshore, it could become a tropical depression later this week.<video src="https://media.weathernationtv.com/app/uploads/2025/07/sphagettis-1752628561366.mp4" controls="true" width="100%"></video><h1>Forecast Factors</h1>Why is the northern Gulf being highlighted for development in the middle of July? Models favor upper-level troughing to develop over the region toward the middle of the week, which is likely to spur lift and heavy rain. An area of high pressure will slide west by Thursday, helping steer our system to the north, into land. Where that happens is still up in the air. It will depend on the strength of both the system and the high.<video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer invest steering-1752603031336.mp4" controls="true" width="100%"></video>Warm water is a necessary ingredient for tropical formation, and temperatures in the Gulf are plenty warm to fuel tropical systems. Typically, sea-surface temperatures in the upper 70s are needed for tropical cyclone development.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Web 2-1752495335806.png">Water temperatures tend to warm more quickly early in the season in the Gulf and western Atlantic. However, with the presence of some elevated wind shear, conditions won't be the richest for development. That interaction with wind shear and some lingering dry air could help limit any rapid development.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-15 055224-1752580353462.jpg">As we continue to iron out the details of this system, check back with the forecast, especially if you have interests along any of the Gulf Coast states.

A cold front pushing through the Eastern Seaboard was responsible for dozens of reports of flash flooding on Monday, so much so that the Governor of New Jersey declared a State of Emergency for flash flooding.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1945122429342282186" src="https://x.com/WeatherNation/status/1945122429342282186"></div><img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-14 205829-1752548331902.png">The flash flooding in the Northeast on Monday led to airport delays at Newark, JFK, and LaGuardia.

Alana Cameron was born and raised in Canada in the city of Mississauga, just outside of Toronto. Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation.

A strong July cold front is racing through the Northern Rockies and Dakotas. Cities that were in the 90s are now in the 60s. That cold front and temperature contrast also sparks a severe weather risk. Temperatures are well below average across the north-central plains.<img src="https://media.weathernationtv.com/app/uploads/2025/07/cooler air-1752628088005.png"><h1>Severe Weather Outlook</h1>SPC has issued an Enhanced Risk (level 3 out of 5) for severe weather overnight.

It has been 10 days since the devastating floods swept through the Texas Hill Country, and our hearts remain with the communities still recovering. And before they could catch their breath more rain inundated the same region once again.

Keep the rain boots handy in Florida - heavy rain is expected to inundate parts of the state from the end of the weekend into the middle of the upcoming week. Rainfall totals are expected to average 3-6" in Central and South Florida, with higher totals likely for areas that see multiple heavy downpours. Some locations may end up with 7-10" of rain by the time this storm system moves out.This system could develop into our next tropical system.

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.

Friday was another busy day with severe weather and flash flooding. A Flash Flood Emergency was issued for Davenport, IA after they picked up over four inches of rain. The winds from Friday's storms were over 70 plus mph!<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-12 055745-1752321471706.png"><h1>Timing</h1>Friday's leftover storms will be the catalyst for additional shower and thunderstorm development across parts of the Ohio Valley and Great Lakes region on Saturday, as will the frontal boundary that moves into the region. The surface low could also help to spur a few supercells, capable of producing a tornado or two in eastern Michigan, primarily from the late morning through mid-afternoon.<h1>SATURDAY</h1><video src="https://media.weathernationtv.com/app/uploads/2025/07/FORECAST-1752352202968.mp4" controls="true" width="100%"></video>As the front continues to move, strong thunderstorms may redevelop early Saturday over the central High Plains. Behind the front, a high-pressure system ushering in cooler, drier air from western Canada will settle over the northern High Plains, bringing a temporary break from the stormy conditions. <img src="https://media.weathernationtv.com/app/uploads/2025/07/PIC 1-1752352628146.jpg">Rainfall rates will remain high, with 1-2" of rain per hour possible.

Colorado will get a good dose of snow tonight and through tomorrow morning. Winter weather alerts are in place for much of Central and Southern Colorado extending into parts of New Mexico.

If you live south of Denver, this will mean some snow will accumulate on those pumpkins tonight but no worries.....it does appear the moisture moves out just in time for trick-or-treating.

This will mean your morning commute to work tomorrow might be a bit on the treacherous side as snow will still be falling. Snowfall amounts will range from 3-6 inches of heavy, wet snow that will stack up fast overnight tonight..

The highest snowfall will be south of Denver. The San Juans and Sangre De Cristo will end up with close to a foot of snow for elevations above 7,000 feet.
