Storm Tracker Forecast: Hot today, but cooling down late week

We'll be staying hot today, but a substantial cooling trend and the potential for showers are returning in your late week and weekend forecast.

Posted: Oct 7, 2020 6:25 AM

The heat continues in your Wednesday forecast, and we'll continue to be very dry today. High pressure to our southeast continues to be the dominant features impacting our forecast today, but low pressure approaching the coast to our south will bring some modest changes this afternoon. Air quality continues to be good to moderate in the valley, foothills, and Sierra this morning but is in the unhealthy to very unhealthy range in portions of Trinity and Siskiyou Counties. Temperatures are starting out in the 50's in the valley, 50's to 60's in the foothills, and 30's to 50's in the mountains this morning. Winds are mostly out of the north early today, but will shift to become out of the southeast this afternoon. Humidity will dip to below 20 percent across our region later today, with some areas potentially ending up below 10 percent. High temperatures will top out in the upper 80's to lower 90's in the valley, and in the low to mid 80's in most foothill and mountain areas. Fire danger will remain high due to the hot and dry conditions this afternoon.

The cooling trend we've been talking about all week finally arrives on Thursday as low pressure approaches central California from the Pacific. This will leave valley areas topping out in the mid to high 70's on Thursday, while higher elevations end up in the 60's to 70's. We'll be around 2 to 5 degrees cooler on Friday, but unfortunately models are keeping wet weather to our south now. An area of low pressure is then projected to move through to our north as we head into the weekend. That will bring temperatures down into the upper 60's to low 70's in the valley on Saturday and leave mountain areas mostly in the 50's to low 60's. Showers will be possible as this system moves through to our north, but the latest models are showing very light amounts. We'll then dry out on Sunday, and warm back into the mid 70's in most valley areas. High pressure moving in from the Pacific will bring a warming trend and stronger north winds back into our forecast early next week. Valley temperatures will return to the low to mid 80's, while mountain and foothill areas end up back in the mid to high 70's. Winds up to 20mph out of the north will be possible, and gusts will likely be stronger than that. This will increase concern for fire danger early to mid week next week. Enjoy the much cooler conditions while they last, because this looks to be a very shortlived dip of our toe into the fall like weather.
