Weather Underground Forecast for Saturday, November 17, 2012.
Wet weather continues in the West, while the East remains dry and quiet on Saturday. Two areas of low pressure will merge over the West Coast on as a low pressure system drops in from the Gulf of Alaska and a another trough of low pressure slides over California. As these systems will continue pushing abundant moisture onshore, bringing more rain showers to the West Coast, with snow expected in the Cascades and the Sierra Nevadas. Expect heaviest rain and snow showers to develop along a cold front that moves onshore by Saturday evening. Higher elevations may see over a foot of snow through Saturday night, while lower elevations may see up to an inch of rain. Strong winds will also develop along this front with gusts from 65 to 75 mph at highest mountain passes.
Meanwhile, in the East, dry and quiet conditions will prevail as high pressure remains the dominant weather feature. This will continue pulling cool air in from the north, maintaining chilly Fall temperatures. High temperatures will remain in the 30s and 40s in the North, while the Eastern Valleys will see highs in the 50s and 60s. Further south, expect for an area of showers and thunderstorms to move up the coast from eastern Florida through the Carolinas. These storms will be light and limited to the coastal areas.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 6 degrees at West Yellowstone, Mont. to a high of 78 degrees at Hollywood, Fla.
