No need for that jacket as you're getting ready to head out the door this morning, but some of you may want to have an umbrella handy. Our forecast continues to be influence by low pressure off the coast to our west, and high pressure centered just off to our east. The low pressure off the coast will have a bit more influence today, and will bring a modest dip in high temperatures, breezy south winds, and the potential for scattered showers to areas from Shasta County to the coast and Oregon border. High pressure to our east will keep most of us dry, and will keep out temperatures at least close to the average for this date today. Some clouds are brushing through the Northern Mountains and Shasta County for the start of your Monday, while the rest of our region remains mostly clear. The best chance for showers will stay in the Northern Mountains today, but there is also a decent chance for at least some light precipitation in the Shasta County mountains through the day. Temperatures are starting out in the 60's to low 70's in the valley, 50's to lower 60's in the foothills, and in the 40's to 50's in most mountain areas this morning. Winds will be out of the south in the 10 to 20mph range, with gusts up to around 30mph through the day. High temperatures are projected to end up in the mid 80's to around 90 degrees in the valley, upper 60's to lower 80's in the foothills, and in the upper 60's to upper 70's in our higher elevations this afternoon. Humidity will dip to below 30 percent. Our fire danger will end up in the moderate to high range due to the gusty south winds through the day.
Low pressure will track through the coast to our north from tonight through Tuesday, and the high pressure to our east will build into northern California. This will result in sunny to mostly sunny condiitons, the return of north wind, and temperatures warming by several degrees compared to Monday. We'll still end up just around average for this time of year. We'll be dry, with high temperatures in the upper 80's to lower 90's in the valley. We'll have high temperatures in the 70's to mid 80's in the foothills and mountains on Tuesday afternoon. The heat will ramp up on Wednesday as high pressure continues to build across the southwest. Triple digit high temperatures are in store for the valley on Wednesday, and we'll end up in the 80's to 90's in the foothills and mountains. An Excessive Heat Watch is set to go into effect for the valley and foothills on Thursday afternoon, and is currently set to stay in effect through Saturday evening. This will very likely be upgraded to an Excessive Heat Warning as we get closer to Thursday, and it may be extended through Sunday. Valley areas will range from 104 to 113 degrees from Thursday through Sunday, while we end up in the 90's to triple digits in our mountain and foothill areas. The heat is a major concern and will be dangerous late this week through this weekend. We'll also be very dry, with plenty of sunshine as the high pressure dominates the southwest. Make sure to plan ahead to get your outdoor activities done in the morning, drink plenty of water, dress for the heat, and keep a close eye on your loved ones during this dangerous heat event.
