Daily briefing: Monsoon brings flood threat

Monsoonal moisture brings the risk of flash flooding in the Southwest. Cooler air holds steady across the Plains, Midwest and Northeast, while the heat remains persistent in the Pacific Northwest. These details, along with our daily tropical outlook, are published every weekday at 5 a.m. ET.

Showers and storms will dot the Plains and Southwest today, bringing the threat of flooding, especially in the Southwest, where monsoonal moisture may produce some heavy downpours.

The eastern half of the country will remain mostly dry, with just a few showers developing along a stalled front, and seabreeze thunderstorms forming in Florida. Much of the Plains, Great Lakes and Northeast will experience cooler-than-average temperatures and sunshine.

Temperatures will stay above average across the Pacific Northwest while more comfortable highs in the 70s and 80s stretch from the Plains to the Northeast. Keep an eye on the TemperatureRadar to see if more comfortable highs are in your forecast.

Tropical Storm Fernand is northeast of Bermuda and continues to move north-northwest. This storm will not impact land and is expected to dissipate by the end of the week.
