Big Changes Through the Weekend

By Staff

Published Oct 17, 2012 12:12 PM EDT | Updated Oct 18, 2012 3:15 AM EDT

Copied

Some big changes will take place from the weather experienced today to the weather by the weekend and early next week up and down the West Coast.

In central and Southern California and the Southwest, the above-normal temperatures, and in some areas just plain old hot weather, of late will be going about a bit of a cooling process. By the weekend, temperatures will be near normal in the Desert Southwest but below normal for coastal and coastal valley areas. High temperatures by Saturday and Sunday in places like Los Angeles and San Diego will be 20-plus degrees lower than today. A return of morning low clouds is also likely in these areas. In the Central Valley, it won't be quite as dramatic but a good 10 to 15 degrees of cooling is likely.

In the Northwest, wetter, and in some areas whiter, weather is likely along with colder temperatures. A strong and cold upper-level trough will develop south of the Gulf of Alaska. This will eventually form a cold upper-level high off the Northwest coast early next week. This is likely to bring periods of rain west of the Cascades and some showers east along with a big drop-off in temperatures. Snow is likely to fall in the Cascades with snow levels dropping below pass level in Washington state by Sunday. Next week it's likely to get even chillier with even lower snow levels and additional showers or rain along with snow in the mountains.
