Weather Underground midday recap for Saturday, May 17, 2008. A low pressure system off the New England coast continued moving northeastward into the Canadian Maritimes. Wraparound moisture produced morning precipitation in coastal New England.

Behind this system, a cold front swept through the Great Lakes and into the Northeast. There was not a lot of moisture associated with this front, but scattered showers were reported from Wisconsin and Michigan through New York and Pennsylvania.

Farther to the south, moisture from northern Mexico streamed north of the border and into New Mexico and Texas. Scattered showers and a few thunderstorms were produced from this moisture.

A very strong ridge of high pressure that has brought warm to hot temperatures the past few days continued to supply warm air to much of the West. There was some cooling in sight for coastal areas as the marine layer was once again approaching from the ocean.

The Northeast rose into the 60s and 70s, while the Southeast saw temperatures in the 70s and 80s. The Northwest rose into the 80s and some 90s, while California saw inland temperatures in the 90s and 100s.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of 26 degrees at Berthoud Pass, Colo. to a midday high of 105 degrees at Palm Springs, Calif.
