The nation's weather

[July 09, 2010] (AP) High pressure over the East Coast was expected to finally push eastward due to an incoming front from the central U.S. on Friday.

A low pressure system moving through Canada would continue pulling a cold front through the country. The system would start the day over the Great Lakes and mid-Mississippi River Valley and move southeastward into the Northeast, stretch down the Ohio River Valley and into the lower Mississippi River Valley. The system would kick up scattered showers and thunderstorms, some of which may turn severe as ample moisture feeds into it from the Gulf of Mexico. This slow-moving system would allow for another heavy flooding day for the Mississippi River, as well as the Ohio River. Rainfall totals up to an inch along the front were expected, with closer to 2 inches in areas of severe storm development. As this system moved eastward, the East Coast would be alleviated from hot temperatures and would not remain under a heat advisory much longer, as highs returned to the upper 80s.

In the south, the remnants of Tropical Depression Two would continue skirting through Texas and northern Mexico. Flow around the system would pull moisture in from the Gulf, allowing for periods of heavy rain to develop throughout the day. This would bring another round of heavy flooding to the region.

Out West, mild weather would persist as a ridge of high pressure lingered over the West Coast. A few patchy clouds may linger along the coasts, with plenty of sunshine and warm conditions inland.

Temperatures in the Lower 48 states Thursday ranged from a low of 35 degrees at Monarch Pass, Colo., to a high of 107 degrees at Williams Gateway Airport, Ariz.
