Get ready for another hot and dry day across Northern California. Skies will be sunny, but still hazy from the current wildfires burning in Northern California. Air quality is improved compared to yesterday afternoon, and will more than likely stay in the moderate or good range for your Tuesday. Temperatures have dipped into the low to mid 60's in the valley overnight, and into the 40's to 50's in the mountains this morning. Winds are starting out of the Northeast to around 8mph, but will be out of the South to 10mph today. The Delta Breeze will have very limited cooling impacts, but should help to keep high temperatures from getting hotter than yesterday. Humidity is expected to dip into the 10 to 30 percent range this afternoon. High temperatures are projected to end up in the mid 90's to low triple digits in the valley this afternoon, and in the 80's to 90's in the mountains later today. The dry and hot conditions will result in high fire danger across the region today. Make sure you're dressed for the hot weather as your getting ready this morning, and please don't forget to stay hydrated.

There is a very subtle but welcome cooling trend on the way for the rest of the week. Temperatures are projected to be in the mid to high 90's on Wednesday, and will then fall back into the low to mid 90's for the end of the work week. Clouds will make their way back into Northern California towards the end of the week, but we are expecting to stay dry through your extended forecast. Temperatures will stay in the low to mid 90's for your upcoming weekend, and low temperatures are expected to fall back into the mid to high 50's in the valley by the latter part of this week. There are conflicting projections for our forecast next week. One solution is warmer, while the other continues the cooling trend. We're going with the cooler solution for now, but that is subject to change if the models start leaning towards the warmer trend.

Wednesday was a scorching day for parts of the valley as northerly airflow really warmed our temperatures. The breezes will continue Thursday, but their direction will shift and it will be slightly cooler.
