Birds – and butterflies – are migrating south for the winter. There are so many that we can see them on radar! Senior meteorologist Matthew Cappucci has an update.

SURPRISE! A new tropical storm appears to be forming about 400 miles west-southwest of the Azores. This was not in the forecast.

The National Hurricane Center now estimates a 60 percent chance that "Fay" forms by Friday evening.

It formed thanks to a swirl of counterclockwise "spin", or vorticity, spun up on the western side of a clockwise-spinning high pressure system. That lobe of spin was anchored beneath a weak upper-air trough, or low pressure system, that encouraged thunderstorms to form over water temperatures around 82 degrees.

A cohesive, low-level center appears to be forming, and convective (thunderstorm) development is deep (tall) enough that this system will probably be named soon.

It should remain southwest of the Azores and pose little/no threat to land.

Honestly, we're not expecting much out of today's low-end severe weather risk in Iowa.

Despite a juiced-up lower atmosphere, there is a stout "cap" at 3,000-5,000 feet, working to suppress storm growth. Models don't even simulate any!

If one forms, brief, isolated tornado risk.

Isolated severe weather is possible this evening in Iowa.

A greater storm chance exits Saturday from the Kansas-Colorado border to Kansas City.

We're seeing lots of hype on social media about a potential system in the northwestern Caribbean.

However, false positives – i.e. simulated storms that NEVER happen – are a known bias of the American GFS model.

Locally significant flooding is likely in the Desert Southwest amid robust monsoonal downpours. There could also be a few severe thunderstorms, especially in Utah. Senior meteorologist Matthew Cappucci has an update.

Thirty years ago this week, “Hurricane Huron” formed over Lake Huron.

It wasn’t exactly a hurricane, but it DID exhibit some curiously tropical characteristics.

We’d probably consider it “subtropical.”

MetNote #9 Issued 2:45 PM ET Tuesday, September 15, 2026 30 years ago this week, something unprecedented happened over the Great Lakes – "Hurricane Huron." Nothing like it has been documented since…

Waves of moisture will propagate along a slow-moving cold front sagging across the Plains and Midwest. A few pockets of flooding are likely, especially near St. Joseph, Missouri. Senior meteorologist Matthew Cappucci has an update.

Robust moisture pooling along a slow-moving cold front is increasing the risk of scattered flooding across portions of the Plains and Midwest.

The risk is greatest north of Kansas City near St. Joseph, Missouri, where 3-5 inches are possible through early Wednesday.

Otherwise, a general 1 to 2 inches is expected from the Texas Panhandle through Iowa and central Illinois.

This is caused by isentropic ascent, i.e. warm, moist and less-dense air spilling up and over a lip of cooler, denser air to the north. As warm air rides over cool air, moisture is squeezed out of the air, forming raindrops.

A hurricane-like system is forming in the Mediterranean. Greece, southern Italy, northern Libya and Egypt should monitor the progress of this system. Matthew Cappucci has an update.
