The nation's weather

[August 18, 2010] (AP) Showers and thunderstorms were forecast to push through the Southeast on Wednesday as a cold front made its way across the region.

This cold front and an approaching trough of low pressure would bring much cooler temperatures to the East, especially the Northeast, where highs would drop between 10 and 15 degrees in some cases. Highs in the Southeast would remain relatively warm, although as storms moved through, afternoon temperatures should drop.

The northern Plains would also see some wet weather as an arctic cold front passed through the region. Temperatures would be cool for August, but not record-breaking.

In the West, monsoon thunderstorms would pop up throughout the Four Corners region as subtropical moisture streamed into the region. Thunderstorms were also possible in the Northwest, where very dry conditions at the surface might cause precipitation to evaporate before it hit the ground, leading to a dangerous fire weather scenario. Temperatures in the Northwestern interior would remain hot with very low humidity. When combined with dry thunderstorms, fires were very likely.

Elsewhere on the West Coast, temperatures would remain below normal, with morning fog and drizzle along the coast. Inland temperatures would be pleasantly warm but still below normal.

Temperatures in the Lower 48 states Tuesday ranged from a low of 31 at Charleston, Nev., to a high of 121 at Death Valley, Calif.
