Weather Summary

Weather Underground Forecast for Wednesday, March 17, 2010.

Another day of mild weather is anticipated over most of the US on Wednesday. A large ridge of high pressure will continue to build over the Central US and stretch over most of the East Coast. However, a small yet intense trough of low pressure will continue to move through the Southeast. It will start the day in eastern Texas and pick up moisture from the Gulf of Mexico as it moves over the Gulf states. Cool air associated with this system will allow for highs to only reach into the 50s and 60s. This system has a history of producing scattered showers and thunderstorms, but if they develop, storms will remain mild and are not expected to turn severe. Rainfall totals will also be light, with up to a half of an inch expected in most areas, up to an inch in the vicinity of thunderstorm development.

Meanwhile, a weak front that moved through the Upper Midwest will lose most of its strength as it moves into the Great Lakes. This may kick up a few cloudy skies, but precipitation is not anticipated. Most of the Midwest, Great Lakes, and New England will see another warm day with highs in the 60s.

In the West, another Pacific Storm pushed a cold front onshore, which will continue moving through the Pacific Northwest on Wednesday. This system has little moisture associated with it, but will bring cool and breezy conditions to the Pacific Northwest. Expect highs in the 50s with winds gusting up to 20 mph. California, however, will see another warm and sunny day with highs in the 70s.

Temperatures in the Lower 48 states Tuesday ranged from a low of 7 degrees at Leadville, Colo. to a high of 84 degrees at Camp Pendleton, Calif.
