A quiet weather pattern will remain for most of the nation today. However, a pesky low pressure system causes trouble in the north-central U.S., while a few other weather headaches develop in the Northwest, Northeast and Florida.

This pesky low pressure system will slowly slide from the central Plains into Midwest and Ohio Valley for the middle of the work week. There will be a warm front ahead of the low pressure system, with a cold front slicing across the nation’s midsection. If that wasn’t enough, a reinforcing cold front will drop south across the northern Rockies and northern Plains.

The result will be chances for precipitation from the northern Rockies and northern Plains into the Midwest and Great Lakes throughout the day. Snow will pile up in the northern Rockies, with a rain/snow mix for the Upper Great Lakes. The northern Plains, Midwest and Lower Great Lakes will see rain showers. Rain will also likely move into the Ohio Valley in the evening.

The other troublesome areas today include the Northwest, Northeast and Florida. A new Pacific storm system will bring rain and mountain snow showers to the Northwest late in the day and night. There could be a few flurries or snow showers early in the day across interior New England as a storm system moves out of the region. Florida could also see a few rain showers due to a stalled front just off the coast.

Otherwise, a large portion of the nation will see dry, quiet weather today. This includes California into the Four Corner states and south-central U.S. as well as most of the Southeast and Mid-Atlantic.

The coldest spot in the Lower 48 will be the interior Northeast, where temperatures will only peak in the 20s and 30s. Expect 40s and 50s for the Great Lakes, Upper Midwest and Ohio Valley into southern New England and the Mid-Atlantic. The tallest parts of the Mountain West will also observe highs generally in the upper 30s and 40s.

Milder 60s and 70s will dominate most areas. This includes the Northwest, the northern half of California and the rest of the Rockies into the northern half of the Plains, most of the Mississippi Valley, the Deep South and Southeast. Eighties will be widespread across the southern Plains, with 80s and 90s in southern California and the Desert Southwest.
