The nation’s weather

Weather Underground midday recap for Saturday, July 13, 2013.

Wet weather continued in parts of the East on Saturday as a frontal boundary stalled across the Mid-Atlantic coast and Southeast. Ample moisture streaming across the region aided in producing areas of scattered showers and organized thunderstorms with periods of locally heavy rainfall from the Florida Panhandle through the Mid-Atlantic States and southern New England coastal areas. Areas of the Florida Panhandle through coastal areas of the Mid-Atlantic remained at risk of heavy rains and increased risks of local flooding and flash flooding through the day.

Behind this activity, showers and potentially strong to severe thunderstorms continued in the Northern and Central Plains into parts of the Upper Midwest as a frontal boundary reached from North Dakota into the Northern Rockies by the late afternoon and a trough of low pressure extended through the Plains. The Storm Prediction Center issued a slight risk of severe thunderstorm development for parts of the Northern Plains through the afternoon. Damaging wind gusts and large hail may develop in these areas due to strong unstable environmental conditions.

Finally, out West, monsoonal moisture streamed across the Four Corners and triggered chances of showers and thunderstorms.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 32 degrees at Truckee-Tahoe, Calif. to a midday high of 105 degrees at Hays, Kan.
