A very active week is now underway, beginning with scorching hot temperatures Monday afternoon. Triple digits are expected over West Side Valleys and Northern California today. Morning clouds and fog at the coast will gradually clear into midday. Isolated thunderstorms are possible into this evening east of the Cascades and over Siskiyou County.
A widespread event is likely Tuesday ..meaning lots of thunderstorms with frequent lightning, even for the West Side. Showers and storms will likely begin popping up by mid afternoon. Strong winds, small hail, locally heavy rain and frequent lightning will all be threats with these storms. Today, the storms will be on the drier side but as moisture continues to stream in over the next 48 hours …heavy rain is more likely.
Either way, the lightning threat is of big concern this week. An upper level low in the Gulf of Alaska, plus monsoonal moisture over the Desert Southwest will help to filter in moisture all week long. Each day another round of showers/storms are likely through the end of the week and into the weekend for the Basin and Shasta Valley. For the West Side, best bet for storms looks to be Tuesday and Thursday. We will likely see fire weather watches/warnings all week long. Temperatures will stay hot as well, in the 80’s and 90’s depending on location.
The timing of each round of storms will change from day to day so keep it here with Newswatch 12 for the latest updates. Lots to watch out for this week! You can find more information on Facebook and/or Twitter!
