BREAKING NEWS Chico Police looking for 20th Street Park stabbing suspect Full Story

A warming trend & more mountain thunderstorms ahead

The threat of showers and thunderstorms continues across the mountains, and there is a slight chance for active weather in the valley today.

Posted: May 17, 2018 6:35 AM

More active weather is on the way for your Thursday, but will not be as widespread as what we've had over the last two days. There will be a very modest chance for a stray shower or two, and a thunderstorm popping up in the valley late today, but that doesn't look all that likely at this time. The best chance for showers and thunderstorms will be in the Sierra this afternoon and evening, but there is also a decent chance for some active weather to brush across the Northern Mountains and Sierra Foothills later today. Temperatures are starting out slightly warmer for your morning, with valley areas dipping into the 50's to low 60's overnight, and mountain areas ranging from the mid 40's to low 50's early today. Skies are starting out mostly cloudy, but we are expecting some clearing to result in partly cloudy skies in the valley this afternoon. Mountain areas will stay mostly cloudy, and become active later today. Winds are projected to be light, and humidity will dip to as low as 30%. Those conditions, paired with slightly warmer high temperatures will result in low to moderate fire danger this afternoon. Thunderstorms will elevate the concern for fire danger late today. High temperatures will end up in the low 80's in the valley later today, and in the 60's to 70's in the mountains this afternoon. Showers and the chance for thunderstorms will persist into the evening for the Sierra.

Mostly dry, and slightly warmer weather is on tap for your Friday. Temperatures will start out in the same range as today, but will become around 4 or 5 degrees warmer for the afternoon. Valley areas and the Northern Mountains are projected to stay dry on Friday, but we could see more active weather popping up across the Sierra from Plumas County down to the South. Saturday will be similar to Friday, but might get a little warmer. There will be a chance for Sierra showers and thunderstorms but most areas look like they'll stay dry elsewhere. Temperatures will become slightly cooler on Sunday, and the chance for active weather will become a bit more widespread. Most valley areas will stay dry on Sunday, but Redding will have a decent chance for some wet weather passing through. Both the Sierra and Northern Mountains will likely have showers, and the chance for thunderstorms on Sunday.

Temperatures will stay in the high 70's to low 80's in the valley for the start to middle of next week. There is a decent chance for more active weather ramping up on Monday, and slowly tapering off through Wednesday. We'll have a much better idea of what's in store for next week as we get a little closer, as models are currently split on what to expect from Tuesday through the end of next week.
