Area Forecast Discussion National Weather Service Sacramento CA 202 PM PDT Thu Jul 29 2021
SYNOPSIS. Late day mountain thunderstorm chances expected through the weekend. Above normal temperatures are expected through Friday with a slight cooling trend for the weekend and early next week.
DISCUSSION. Ridge of high pressure remains centered over much of the Central US with the western edge situated over California. This will continue to bring southwest flow into interior Northern California, drawing in monsoon moisture into the area. Afternoon and evening shower and thunderstorm chances continue over the next several days. Thunderstorms already began forming over the Sierra late this morning, and best chances will remain along and east of the Sierra crest south of Plumas County and along the Coastal Range. Better chances of more widespread mountain showers and thunderstorms are possible tomorrow as the potential spreads north into the Shasta County mountains. Any thunderstorm may be accompanied by gusty and erratic winds, brief downpours, and lightning.
Temperatures are forecast to remain above normal through tomorrow as high pressure remains over the area. Current temperatures around 1pm are overall similar to yesterday, and highs are forecast to top out around 100 to 108 degrees in the Valley and upper 70s to upper 90s in the mountains and foothills. Overnight temperatures are forecast to be fairly toasty once again tonight, only falling to the low to mid 70s in the Valley and foothills with some thermal belt locations in the foothills only falling to the low 80s. Wildfire smoke continues to impact temperatures around the Dixie Fire. Smoke is forecast to continue the diurnal flow that's generally been observed by draining into the northern Valley in the early morning hours before the southwest flow increases and pushes it back to the north/northeast.
An upper level trough forming off of the eastern Pacific Coast will lower heights over Northern California this weekend, moderating temperatures. Temperatures are forecast to fall back to near normal by Saturday, which is 90s across the Valley and foothills and 70s to upper 80s in the mountains. -HEC
EXTENDED DISCUSSION (Monday THROUGH Thursday). Northern California will likely see southwesterly onshore flow over the region throughout the extended forecast period. Cluster analysis is in agreement high pressure over the Southwestern US and troughing off the Pacific Northwest Coast will keep Northern California near seasonal temperatures with little day to day change in the forecast. Thermal belts will also continue to see mild overnight lows. This pattern will also support a Delta Breeze. Some discrepancies emerge by the later part of the week in terms of the depth and location of the trough off the Pacific Northwest Coast. This could lead to some changes in the forecast from persistence by the weekend.
AVIATION. VFR conditions at TAF sites with passing mid to high level clouds AOA 15K ft AGL. Local MVFR/IFR conditions in wildfire smoke over Plumas and Butte counties. Surface winds under 12 kts except local southwest gusts 25-30 kts vicinity west Delta. Isolated-scattered showers and thunderstorms over high elevations of the Sierra south of Tahoe with isolated activity north of Tahoe through 03z, weakening to isolated showers and dissipating after 07z. Chance of MVFR weather in heavier storms with isolated downdrafts G40 kts lee-side of Sierra. Temps AOA 105 deg F will result in density altitude 3000-3500 ft Thu and Fri afternoons.
STO WATCHES/WARNINGS/ADVISORIES. None.
