The nation’s weather

Weather Underground midday recap for Sunday, June 09, 2013.

The remnants of post-tropical cyclone Andreas continued on an east-northeast track away from the New England coast toward southern Newfoundland, Canada on Sunday. Rain and windy weather conditions impacted portions of Atlantic Canada through Sunday before the system became absorbed by another low pressure system east of Newfoundland later in the day.

Behind this activity, a storm system from the Plains trekked eastward into the Midwest on Sunday. The main low associated with this system ushered ample moisture from the Gulf of Mexico northward into the East as it moved across the Mid-Mississippi Valley toward the Ohio Valley and it¼’s associated warm front reached across the Ohio Valley and the Mid-Atlantic. Areas of scattered showers and thunderstorms spread northward from the Central Gulf Coast States through the Midwest as the system progressed. Heavier precipitation and stronger thunderstorms developed ahead of an associated cold front that reached from the low through the Southern Plains. The Storm Prediction Center issued a slight risk of severe weather for the Lower to Mid-Mississipppi Valley and the eastern Tennessee Valley and Lower Appalachians vicinity. Severe thunderstorms in these areas had the potential to produce locally damaging wind gusts and large hail.

Finally, out West, the strong high pressure system that supported extreme heating in the inland areas of California and the Desert Southwest during the last couple of days began to shift to the east on Sunday. This transition allowed a cool down to begin over the region. A closed low off the California coast also moved inland over California and triggered chances of showers in parts of the central valleys and the Sierra Nevadas.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of 32 degrees at West Yellowstone, Mont. to a midday high of 104 degrees at Henderson, Nev.
