849 FXUS66 KSTO 042102 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 102 PM PST Wed Dec 4 2024 .SYNOPSIS... Areas of low elevation morning fog persist through much of the week ahead alongside otherwise dry and gradually warming weather. More seasonable temperatures and breezier winds then expected through the weekend into early next week. .DISCUSSION... Morning fog dissipated some time around 10am and conditions are clear today otherwise on GOES Visible Satellite Imagery. Temperatures are near normal to slightly above normal across the area today, with Valley highs in the 60s, and 50s to 60s at higher elevations. The forecast remains much the same the rest of the week, as high pressure remains over NorCal. On Saturday, a shortwave trough is expected to move onshore near the Pacific Northwest which, while not expected to bring much moisture, will lower temperatures slightly. There is also a 5 to 10% chance of 0.01 inches of measurable precipitation, though this is not very likely. // SP/JB, PhD .EXTENDED DISCUSSION (Sunday THROUGH Wednesday)... Upper ridging builds inland Sunday into Monday with some gusty north to east wind. Pressure gradients relax Tuesday morning, but tighten again over the northern and eastern foothills and mountains Tuesday night into Wednesday morning and again Wednesday night into early Thursday. NBM advertising some precip chances over northern portions of the CWA Wednesday, but forecast confidence is low. // SP/JB, PhD && .AVIATION...
