The main weather story for the nation on Saturday will be the heat out West, specifically the Desert Southwest.

Hot temperatures are anticipated across the Desert Southwest and spreading northward across the Western states as a strong ridge of high pressure continues building northward. This will create warm, dry, and sunny conditions.

Excessive-heat advisories have been issued for many areas as high temperatures may reach over 115 degrees for the desert locations. Record-breaking high temperatures are likely for areas near Las Vegas, Phoenix and Death Valley Expect high temperatures in these areas to range from 115 to 120 degrees on Saturday.

Meanwhile in the East, a broad low pressure system over Eastern half of the nation will allow for a frontal boundary to continue sliding southeastward throughout the day. This will trigger more showers and thunderstorms along the East Coast from the Northeast through the Gulf of Mexico. There is a slight chance that these storms will turn severe with strong winds and large hail.

Shower and thunderstorm activity will also persist behind this system from the Great Lakes through the Midwest and Eastern Valleys.

Temperatures in the Lower 48 states Friday ranged from a morning low of 36 degrees at Stanley, Idaho, to a high of 108 degrees at Palm Springs, Calif.
