Weather Underground Forecast for Friday, May 23, 2014
A cold frontal boundary will extend from the southern Plains to the Mid-Atlantic on Friday, while a separate cold front will approach the northwestern corner of the country.
A cold frontal boundary will continue to interact with warm, muggy air from the Gulf of Mexico to trigger widespread showers and thunderstorms across the NationÂ's midsection on Friday. Strong to severe thunderstorms will be possible over western Texas and southeast New Mexico, while strong thunderstorms will also develop across the Intermountain West, the central Plains and the southern Plains. These thunderstorms will be capable of producing large hail and dangerous straight line winds. Along the eastern end of this frontal boundary, an area of low pressure will bring rain and thunderstorms to the Tennessee Valley, the Mid-Atlantic and the Northeast. High pressure will keep the upper Midwest and the Ohio Valley clear of precipitation, while a separate high pressure system over the Gulf of Mexico will keep conditions clear across the Gulf Coast and the Southeast.
Out west, a cold frontal boundary will approach the Pacific Northwest on Friday. This system will push showers across Washington, Oregon and parts of northern California. The Southwest will avoid wet weather as a ridge of high pressure continues to linger over the eastern Pacific. Temperatures are forecast to range between the 80s and 90s across the southern California and Arizona deserts.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 24 degrees at Bryce Canyon, Utah to a high of 95 degrees at FENTRESS NALF, Va.
