Weather Underground midday recap for Saturday, July 04, 2009. The most active weather this Independence Day stemmed from a developing low pressure system that moved out of the Rockies and into the Plains. A tremendous amount of moisture streamed ahead of this low pressure system and produced widespread precipitation from the Plains through the Ohio Valley. Some thunderstorms were embedded in this precipitation field, but none were severe in nature.

A front swept through New England and instigated scattered showers through the area. These showers were reinforced by a second front that moved through the area in the afternoon.

Warm Holiday weather was experienced in the Southern Plains and Southeast as Heat Advisories were in effect due to heat indices well into the triple digits.

Warm temperatures were also making parts of the Northwest uncomfortable with some areas experiencing temperatures into the 90s.

The Northeast rose into the 60s and 70s, while the Southeast saw temperatures in the 80s and 90s. The Southern Plains rose into the 90s and 100s, while the Northern Plains sawa temperatures in the 70s.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 35 degrees at Truckee, Calif to a midday high of 106 degrees at Hearne, Texas.
