The nation’s weather

Weather Underground Forecast for Saturday, August 24, 2013.

Little change is anticipated for the nation on Saturday as showers and thunderstorms persist for the Southwest and Rockies, as well as the Southeast and Gulf states. In the Eastern Pacific Ocean, Tropical Storm Ivo continues trekking northward up the coast of Baja California. Expect heavy rainfall and strong winds to develop for the southern portion of the Baja California peninsula on Saturday. At the same time flow around the system will also push abundant moisture northward, bringing moderate to heavy showers and thunderstorms to the desert Southwest starting late on Saturday. Lighter and more widespread showers and thunderstorms will expand northward over the Great Basin and Central Rockies, into the Northern Rockies. Fire danger will also remain high for these areas due to increased lightning activity.

Meanwhile, in the East, moisture from the Gulf of Mexico continues pouring northward into the Southeastern states. This will maintain shower and thunderstorm activity from eastern Texas through South Carolina. Meanwhile in the North, a low pressure system moves off the northern Rockies and advances northeastward into central Canada. This will push a warm front into the northern Rockies and upper Midwest, which will kick up a few more scattered storms from northern Minnesota into the Great Lakes.

Temperatures in the Lower 48 states Friday have ranged from a morning low of 33 degrees at Truckee-Tahoe, Calif. to a high of 104 degrees at Mesa, Ariz.
