Weather Underground Forecast for Saturday, September 28, 2013.
A cold front will continue to inch closer to the Pacific Northwest on Saturday, while a ridge of high pressure will keep the Northeast cool and dry.
Moderate to heavy rain will dampen the Pacific Northwest on Saturday as a strong cold front boundary approaches the coast. Considering the amount of rain the Pacific Northwest has been receiving, flooding will definitely be possible in Washington, Oregon, Idaho, and western Montana. Rain may also move as far south as northern California on Saturday as the system moves southeastward towards the states. The Great Basin will experience drier conditions on Saturday as a cold front moves out of the region and into the central U.S. Rain and thunderstorms can be expected from the southern Plains to the upper Midwest on Saturday as a cold front boundary will stretch from Texas to Minnesota. Rain will also be possible in the Ohio River Valley towards the end of Saturday. Meanwhile in the Northeast, a high pressure system will continue to usher cool, dry air in from Canada. This system will keep the majority of the East Coast dry through Saturday. The Southeast may experience spotty showers and thunderstorms due to a low pressure system off of the Atlantic coast. This system may draw a moist air mass into parts of Florida and Georgia on Saturday, which could spur some afternoon thunderstorms.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 21 degrees at Truckee-Tahoe, Calif. to a high of 96 degrees at San Antonio Stinson, Texas
