Today is going to be windy & dry which means high fire danger. A smoky haze will also remain for the forseeable future.
A low pressure system from Canada slid south into Utah. This is what us meteorologists refer to as an inside slider system. High pressure will be pushed to our west due to this inside slider. This will cause a very sharp surface pressure gradient along the Sierra Nevada. This means pressure will drop rapidly the farther east you are. This sharp change in pressure will bring very strong north to east downslope winds into our region. Wind gusts could get up to 30 mph in the valley and top off at 50 mph in the foothill & mountain regions, especially in canyons and along ridgelines such as in Jarbo Gap. The windiest time will be this afternoon. Downslope winds are also very dry, with daytime humidity across the region expected to fall between 5 and 15%. The windy, dry weather has causeed a RED FLAG WARNING to be issued for today through Wednesday morning.
Yesterday record highs were broken again but today we are much cooler with many only reaching the low-90s this afternoon. We'll keep this cooler weather the next few days.
We'll warm up slightly Thursday-Saturday, with some possibly back into the upper-90s, but Sunday and Monday cool back down with another low-pressure system nearing the regions. Valley highs on Monday may stay in the upper-80s.
