Today's Weather Outlook

Monsoon rain will continue to headline the weather as August draws to a close, while a disturbance crawls into the Northeast.

The big story for today will be in the Southwest, where monsoonal showers and thunderstorms will continue to pummel Arizona, Utah and western Colorado. Flooding of typically dry washes is possible, so use extreme caution if you see water on the road.

The Gulf coast will have showers and a few thunderstorms to contend with as an area of low pressure tries to organize into a tropical depression along the Louisiana coast. Regardless of its success, drenching downpours can be expected from the Louisiana-Texas border all the way into Florida.

The other area to receive weather trouble will be from the Great Lakes into upstate New York. Here, a warm front will be inching eastward, bringing a parade of thunderstorms from the Michigan Upper Peninsula to the Poconos and Catskills.

Otherwise, August will wrap up on a sunny note, with high pressure dominating the West Coast, the Front Range, Plains, Ohio and Tennessee valleys, and Eastern Seaboard.

The Northeast will stay relatively cool today, with highs in the upper 70s to lower 80s. Meanwhile, the rest of the East, including the Mid-Atlantic, Southeast, Great Lakes, Mississippi Valley and Plains will see the mercury skyrocket into the 90s and even triple digits. On the West Coast, cooler 60s and 70s will be found near the immediate coast, with 80s common across the Intermountain West. Cloud-cover will help keep temperatures in the 70s to lower 80s from Arizona to Montana, with just a few 90s in place across the California deserts.
