Severe Thunderstorms And Heavy Rain Expected From Ohio Valley To Interior Northeast

Scattered to numerous severe thunderstorms are expected from the Ohio Valley to western New England this afternoon and evening ahead of a strong cold front. Widespread damaging winds and a few tornadoes are possible, mainly over parts of New York into Pennsylvania. In addition, these storms may contain heavy rainfall that could lead to flash flooding.

We will be closely watching a potential tropical cyclone over the western Gulf of Mexico over the next few days. Many of the computer models take this system somewhere along the central part of the coast of TX toward the end of the week. This could potentially mean very heavy rainfall for parts of the area. Stay tuned to the forecast over the next few days for updated track and rainfall information.
Mostly sunny skies and warm conditions can be expected today with highs in the mid to upper 90s and southerly winds around 5-10 mph.
An Ozone Action day will be in effect on Tuesday for portions of North Texas. Conditions will be favorable for elevated levels of ozone pollution. You can prevent ozone pollution by: sharing a ride, walking, riding a bicycle, and keeping your vehicle properly tuned.
A cold front will move into the region Tuesday evening and overnight, bringing better chances for showers and storms to North Texas. The highest chances will be near and north of I-20. Any storms will be capable of producing locally heavy rainfall and strong winds during this period. Chances for scattered thunderstorms will spread to all of North and Central Texas on Wednesday afternoon.
