Colder weather arriving for much of the country

After a few days of warm weather across much of the central and eastern U.S., things will be changing on Tuesday as a strong cold front ushers in a much colder air mass for the middle of the week, according to the National Weather Service (NWS).

For the western U.S., a series of weak disturbances aloft and a surface cold front working its way across the Intermountain West will generate patchy areas of rain from the Pacific Northeast to the northern Rockies.

Given the lack of deep moisture with this system, rainfall amounts are expected to be generally light with snow confined to the highest elevations and north of the border in Canada.

Another area of precipitation worth mentioning will be moisture increasing over Texas and New Mexico from a trough and upper level low situated over Mexico.
