Weather Underground Forecast for Wednesday, Feb. 19, 2014

A cold frontal boundary is expected to move across the Pacific Northwest and Intermountain West on Wednesday, while a weaker cold front will stretch from the southern Plains to the Great Lakes.

Active weather will continue to impact the northwestern portion of the country on Wednesday. A cold front associated with a wave of low pressure is expected to bring rain to the lower elevations across Washington, Oregon and northern California, while the higher elevations will experience mostly snowy weather. Parts of the Cascades and the Rockies are forecast to receive heavy snow showers. The Southwest will continue to stay warm and dry on Wednesday as a ridge of high pressure builds along the coast of southern California.

A separate cold front will stretch across the southern Plains, the lower Mississippi Valley, the Tennessee Valley and the Ohio Valley. A warm, muggy air mass from the Gulf of Mexico will interact with this frontal boundary to produce widespread rain and thunderstorms. This system will also bring light snow showers to the Mid-Atlantic and Northeast, while a coastal system may bring heavy snow showers to northeastern New England. The majority of Georgia and Florida will stay clear of wet weather as high pressure builds off of the coast.

Temperatures in the Lower 48 states Tuesday have ranged from a morning low of -20 degrees at Presque Isle, Maine to a high of 85 degrees at Pecos, Texas
