Weather Underground Forecast for Monday, Nov. 04, 2013.
A cold frontal boundary is expected to stretch from the Southwest to the upper Midwest on Monday, while a ridge of high pressure will build over the Northeast.
A low pressure system will usher wet weather into the Pacific Northwest on Monday, as showers can be expected along the coasts of Washington and Oregon, and snow showers can be expected in the Cascades. Snowy weather may also push across parts of the northern Rockies as a result of this low pressure system. The majority of the Southwest will stay clear of precipitation, although temperatures will drop 5 to 10 degrees due to a recent cold frontal passage.
A cold front is expected to extend from Arizona to Minnesota on Monday, triggering snow and rain across a handful of states. Showers and thunderstorms will be possible across Arizona, New Mexico and parts of the southern Plains, while snow will extend from the central Rockies to the northern Plains. Heavy snow will be possible in Colorado throughout the day. By the evening, wet weather will push into the Mississippi Valley and into the upper Midwest.
The majority of the Eastern Seaboard will stay clear of precipitation on Monday as a ridge of high pressure builds over the Northeast. The exception to this will be along the east coast of Florida, as well as Georgia, where showers and thunderstorms may develop due to an onshore flow from the Atlantic. .
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 8 degrees at Mt. Washington, N.H. to a high of 84 degrees at Tucson, Ariz.
