An area of interest in the Gulf of Mexico has a 50% chance of tropical cyclone formation in the middle of the week, bringing impacts to the gulf coast states. Severe weather is also likely in the upper Midwest on Wednesday, including possibility of strong tornadoes.

Sun 6/14 2 PM EDT: A trough is producing showers and storms over northeastern Mexico, and no development is expected in the next 24-48 h. However, the system could move into the northwestern Gulf by midweek where conditions may become more favorable for development. Heavy rain and flash flooding are possible across parts of Texas and Louisiana this week. Check out hurricanes.gov and weather.gov for the latest information.
Tropical Weather Outlook: 200 PM EDT Sun Jun 14 2026. For the North Atlantic...Caribbean Sea and the Gulf of America: 1. Northwestern Gulf of America: A trough of low pressure located over northeastern Mexico is producing disorganized shower and thunderstorm activity. Development is not expected during the next day or so while the trough remains inland and drifts northward over northeastern Mexico or southern Texas. The system is then forecast to move northeastward and could re-emerge over the northwestern Gulf of America late Tuesday or Wednesday, where environmental conditions may support some development around midweek. Regardless of formation chances, heavy rainfall and flash flooding are possible across portions of eastern and southern Texas and Louisiana this week. Formation chance through 48 hours...low...near 0 percent. Formation chance through 7 days...low...30 percent.

As for next week, organized severe weather may (once again) be present in the Midwest on Wednesday, moving eastward on Thursday. There is also a 20% chance of tropical cyclone development in the Gulf of Mexico later this week (highlighted in yellow).

Yesterday was ultimately very active in the Midwest/Northeast U.S, with large swaths of wind damage observed in both areas; largely isolated activity elsewhere. Likely a lot of weak QLCS tornadoes that are not mapped here as well.

Things have calmed down on the tornado side, with only a handful of persistent supercells south of Chicago being the focus. 2 separate squall lines have formed in Michigan and Illinois, with embedded wind damage/tornado threats.
