The nation’s weather

Weather Underground midday recap for Tuesday, September 10, 2013.

Wet weather continued to pound the Great Basin and Southwest on Tuesday, while excess heat warnings were issued along the eastern Midwest. Thunderstorms remained stalled along the western Gulf of Mexico, as well as the Florida coast.

More thunderstorms swept through the Southwest and Great Basin earlier today, dampening an already saturated area and triggering more flash floods across the region. Flood warnings were issued in New Mexico, Colorado, Utah, and Arizona this morning as a result of persistent thunderstorm activity. Localized rivers and streams were much more vulnerable to precipitation compared to normal situations as thunderstorms have persisted for several days. Meanwhile, the majority of the West Coast experienced warm, dry conditions as high pressure continued to dominate the area.

The Midwest recorded very warm conditions earlier today, sparking excess heat warning advisories. Temperatures exceeded 100 degrees across the eastern Midwest, while the bulk of the area observed temperatures above 85 degrees. Strong thunderstorms were also observed in northwest Tennessee, while parts of the Texas coast also experienced spotty thunderstorms.

The Northeast experienced spotty showers and thunderstorms earlier Tuesday, while temperatures remained in the 60s and 70. The Southeast recorded temperatures in the 80s and 90s, while parts of Florida experienced spotty thunderstorms.

Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 28 degrees at West Yellowstone, Mont. to a midday high of 99 degrees at Jonesboro, Ark.
