The nation's weather

[May 05, 2011] (AP) The strong cold front that brought active weather to the Northeast on Wednesday will move offshore into the Atlantic Ocean on Thursday as its parent low pressure system stalls in Maine.

Wraparound winds associated with this low will usher moisture onshore, creating scattered showers from Vermont through Maine and chances of precipitation in eastern Massachusetts. Temperatures near the freezing mark will allow for some wet snow development in the higher elevations. While rainfall totals in this area are expected to remain low, expect some rivers to remain flooded due to previous soaking rains.

Behind this system, another low pressure system in the central Plains will lift northeastward into the upper Mississippi Valley on Thursday. Periods of light to moderate scattered showers are expected to develop from parts of central and southern Minnesota and northwestern Wisconsin through parts of northern Missouri during the day.

Finally, the ridge of high pressure over the West will start to give way to a trough of low pressure moving into the Pacific Northwest. A cold front will approach the Pacific Northwest coast Thursday, bringing small chances of rain to primarily the coast of northern Washington. Expect chances of rain to increase in the region as we enter the weekend and this trough pushes ashore. To the south, warming along the California coast will wind down Thursday as winds become onshore again. Inland areas of the state see continued warming.

Temperatures in the Lower 48 states Wednesday ranged from a morning low of 14 degrees at Pinedale, Wyo., to a high of 97 degrees at Palm Springs, Calif.
