May 10, 2014 - Scattered showers and isolated thunderstorms possible over the Shasta County mountains and down the Sierra today. Breezy and gusty Northerly winds in the valley today. Below normal temperatures Saturday, followed by dry and above normal temperatures next week. Highs may reach 15-20 degrees above normal by mid week.
Scattered showers and isolated thunderstorms possible over the mountains today as a shortwave moves through Northern California as an upper level low over the Pacific Northwest moves to the southeast. Lingering showers are possible over the Sierra into this evening. People in the mountains should be prepared for rapidly changing weather conditions in the mountains today.
Upper level low over the Pacific Northwest will move to the southeast today. A piece of energy will move around the back side of the low into the far north and down the Sierra Nevada for possible scattered showers and isolated thunderstorms into this evening. Snow levels will lower to around 6000 feet later today.
Breezy to locally windy conditions today for the valley and over exposed areas in the mountains and foothills. Northerly flow will continue over the interior the next several days with easterly winds developing over the mountains tonight and Sunday.
High pressure will build over the region through the middle of next week. Each day temperatures will be getting warmer, warming into the 90s by Tuesday.
Extended Discussion (Wednesday through Saturday)
High pressure will continue to build over California Tuesday through Thursday of next week, with Wednesday and Thursday expected to be the warmest days. On those two days, a few NorCal locations may touch 100 degrees, potentially the first hundred degree days of the year. Forecast highs will be roughly 15-20 degrees above normal, and may be close to record levels.
A shortwave trough is expected to pass through the Pacific Northwest next Friday. This feature should weaken the ridge and bring stronger onshore flow, leading to cooler temperatures.
