Get ready for a cooler start to your Wednesday in most areas and a warmer afternoon on the way for today. Skies are clear and winds are lighter across northern California for the start of your Wednesday morning and that has allowed for more substantial cooling in many areas compared to yesterday. Areas along I-5 are much cooler than 24 hours ago, with both Redding and Red Bluff sitting at around 15 degrees cooler than early Tuesday morning. Valley and foothill areas are starting out in the 30's to 40's this morning, with an inversion layer keeping most foothill areas warmer than the valley. Mountain areas have dipped back into the teens to lower 30's overnight. Skies will be sunny and winds will be out of the northwest to around 10mph in the valley today. Sierra and foothill locations will have winds out of the northeast or east up to around 15mph today. High temperatures are projected to end up slightly warmer than what we had on Tuesday. Valley areas will top out in the mid 60's to low 70's this afternoon, while foothill areas end up in the mid 50's to mid 60's, and mountain areas range from the upper 40's to mid 50's in the Sierra to 50's to lower 60's in the Northern Mountains.
Our forecast is dominated by high pressure off to our east in the Desert Southwest, but we will see areas of low pressure tracking through to our north on Thursday and Saturday into Sunday. This will allow for some thin clouds to track across northern California but no rain is expected through this weekend. The clouds will help to keep low temperatures a little more moderate on Thursday morning and Sunday morning, and will help to keep high temperatures somewhat in check on those two days, but we will still end up well above average for each of the next 7 afternoons. There is little change in the temperature trend through this upcoming weekend. Valley areas will mostly dip into the mid 30's to low 40's overnight, and will top out in the mid 60's to lower 70's. Foothill areas will mostly dip into the 40's in the mornings and end up in the 50's to 60's in the afternoons, and mountain areas will dip into the teens to lower 30's overnight and end up in the upper 40's to lower 60's through this weekend. High pressure will continue to build into our region early next week, and that is expected to bring even warmer high temperatures back into our forecast on Monday. The latest models are showing dry weather through at least the middle of next week, but longer range models are hinting at a wetter second half to your December forecast. We'll be keeping a close eye on the conditions and our fingers crossed for a wet pattern developing across our region.
