<p style="text-align: justify">The National Hurricane Center has 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.</p><video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer invest futurecast-1752602957570.mp4" controls="true" width="100%"></video><h1>Forecast Models</h1><p>Since this is an area of investigation, there are forecast models, known 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.</p><video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer invest spag-1752606518967.mp4" controls="true" width="100%"></video><h1>Forecast Factors</h1><p>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.</p><video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer invest steering-1752603031336.mp4" controls="true" width="100%"></video><p>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.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/07/Web 2-1752495335806.png"></p><p>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.</p><p><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.</p><p></p><p></p><p></p>

Flash Flooding Threat Continues in Texas

<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-size: 13.5pt; color: #454545;">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.

Severe Storm Risk Pushes into the Great Lakes, Ohio Valley

1-1752289754425.png

February is a little longer this year thanks to 2020 being a leap year, but how is that calculated? Hint: It's not every four years! Meteorologist Steve Glazier explains in the video below.

https://youtu.be/S_csshx2Xr8

Here are the basic guidelines for calculating a leap year:
<ul>
 	<li>Any year evenly divisible by 4, except if that year is also evenly divisible by 100, unless that year is also evenly divisible by 400</li>
</ul>
Confused? Be sure to watch the video above! Long story short, it does not take exactly 365 calendar days to make one orbit around our sun. It takes roughly 365.24 days and that extra time needs to be accounted for occasionally to make sure time is correct. That's why an extra day is added on to February every four years (mostly, according to the exceptions above). Enjoy the extra day this weekend!
