Weather Underground Forecast for Wednesday, March 30, 2016
A low pressure system will shift across the central third of the country on Wednesday, while high pressure rebuilds over the West Coast.
A robust area of low pressure will shift east northeastward from the Intermountain West to the upper Mississippi Valley. This system will generate strong winds and moderate to heavy snow across the central and northern Rockies, as well as the central and northern high Plains. Blizzard warnings and winter storm warnings are in place for Wyoming. Winter storm warnings remain in place for Nevada, Idaho and Utah until early Wednesday morning. Winter storm watches are also in effect for eastern Wyoming, western Nebraska and western South Dakota. The same system will draw warm and moist air from the Gulf of Mexico, which will ignite rain and thunderstorms across the Plains, the Mississippi Valley, the Midwest and the Deep South. Severe thunderstorms will be possible across a handful of states, including southeast Nebraska, eastern Kansas, eastern Oklahoma, eastern Texas, Louisiana, Arkansas, western Missouri, southern Iowa, southern Mississippi and southwest Alabama. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Flash flooding will also be possible in southeast Oklahoma, eastern Texas, Arkansas, Louisiana, Mississippi, western Alabama, western Tennessee, western Kentucky and southeast Missouri. Most of the East Coast will experience dry weather, with the exception to showers and thunderstorms over the Florida Peninsula.
Out west, scattered showers and high elevation snow will continue to be possible across parts of California, but the majority of the West Coast will stay clear of precipitation.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 8 degrees at Mt. Washington, N.H. to a high of 87 degrees at Kendall, Fla.
