Weather Summary

Weather Underground midday recap for Monday, February 13, 2012. A storm raced out of the Rockies and into the Plains on Monday, producing a good shot of Winter weather in the Plains and Mississippi Valley. Winter Weather Advisories were posted from eastern Oklahoma through the western Tennessee Valley in anticipation of several inches of new snow. Snow fell as far north as Minnesota and Michigan, but lighter snow was reported the farther north you went. In the warmer air closer to the Gulf Coast, rain fell in Louisiana and Mississippi.

Wet weather also greeted the West Coast as a Pacific storm slammed into California. This storm lacked a tremendous amount of moisture, but it has been a very dry Winter for the state thus far, and any precipitation is very much welcomed. Up to a foot of new snow is possible from this storm in the higher elevations of the Sierra Nevadas when all is said and done.

The East Coast was dry as a high pressure continued to dominate, but the region experienced another chilly day. By the afternoon, temperatures were still in the 20s and 30s for many areas in New England, while temperatures in the 30s were experience as far south as Arkansas. Morning temperatures were in the 20s in northern Florida.

The Northern Plains rose into the 20s and 30s, while the Northwest saw temperatures in the 30s and 40s. The Southwest rose into the 40s, 50s, and some 60s.
