The nation's weather

[April 20, 2010] (AP) Stormy weather with cooler temperatures were forecast to develop across the western U.S. on Monday as a strong spring storm pushed across the California coast.

Increasing instability across California would translate into scattered rain showers and thunderstorms through the afternoon. As this system pushed inland, plenty of Pacific moisture and energy would lift over the mountains and trigger high-elevation snow showers with gusty winds. Winter storm warnings and advisories would remain in effect for the Sierras in anticipation of more snow. By the end of the day, moisture and associated frontal systems would kick up additional precipitation across the Intermountain West and the northern Midwest.

Meanwhile, in the central and eastern U.S., a broad ridge of high pressure was expected to continue producing mostly fair weather conditions from the Plains to the East Coast. Forecasters said a few showers may develop across the southern Plains due to moisture trickling in from the Gulf of Mexico. Active weather was also expected to continue across southern Florida as moist easterly flow spread across the Florida Peninsula.

Temperatures in the Lower 48 states Sunday ranged from a low of 17 degrees at Williston, N.D., to a high of 91 degrees at Goodyear, Ariz.
