Area Forecast Discussion National Weather Service Sacramento CA 308 PM PDT Wed Aug 12 2020

SYNOPSIS. A strong heating trend is expected this week with widespread triple digit highs by late week through the weekend. This is forecast to bring the longest heat wave of the season so far. Isolated thunderstorms are possible over the Sierra Crest south of I-80. Above normal temperatures are forecast to continue next week.

DISCUSSION. After a cool start. temperatures are are generally about 5 degrees warmer than yesterday early this afternoon. Highs in the Valley are expected in the mid 90s.

Main story over the next several days will be the warming trend heading into the weekend. Upper level ridge over the desert southwest will gradually build westward by the end of the week. As a result, the region will experience day-to- day warming into the weekend with triple digit heat becoming widespread as by Friday. Friday afternoon highs have trended warmer, with Valley highs 102-106, so the Excessive Heat Watch has been expanded in time to start Friday afternoon. The Watch continues through early Sunday evening.

Further warming is forecast on Saturday as heat risks reach the moderate to high levels for most communities in the Sacramento Valley and northern San Joaquin Valley. In fact, some locations in the southern Sacramento Valley – such as Sacramento – will be approaching daily record highs around Saturday. The current forecast on Saturday calls for highs around 101-105 deg F in the southern Sacramento Valley / northern San Joaquin Valley, and 103-108 deg F in the northern Sacramento Valley, corresponding to about 8 to 15 deg F above middle August normal climatology. Overnight temperatures are forecast to remain warm with many Valley and adjacent foothill locations remaining in the 70s to low 80s for Friday and Saturday nights. Sunday may be slightly less hot as a shortwave brushes by to the north and heights lower slightly. Overall, though, the ridge pattern will be persistent and will bring a long period of heat.

Southerly flow will bring some monsoonal moisture northward late in the week into early next week. Forcing is limited, but afternoon instability could be enough for some isolated thunderstorms on the Sierra Crest south of I-80.

EXTENDED DISCUSSION (Sunday THROUGH Wednesday). Concluding the weekend, a sprawling ridge of high pressure over the Four Corners will makes its westward move toward the southwestern U.S. At the same time, an offshore trough will open up while shearing as it moves toward coastal Oregon late Sunday night. Some residual moisture will likely lift northeastward with this system from what is currently Tropical Storm Elida. Precipitable water values rise into the 1 to 1.25 inch range into early next week with much of the moisture rooted in the mid to upper levels. This may introduce some shower and thunderstorm activity to the Sierra crest, mainly south of Highway 50 across sections of Alpine and Tuolumne Counties.

The mentioned upper ridge will encourage the continuation of hot weather with highs running around 10 to 15 degrees above climatology. By early next week, the center of the dome of high pressure will be around the Nevada/Utah/Arizona border. Mid-level heights are expected to rise to around 594-597 dm with 850-mb temperatures up to 26-29C. This will perpetuate the threat of excessive heat as high temperatures remain in the 100-105 degree range. Moreover, little overnight relief is anticipated as low temperatures stay in the 70s, locally near 80 degrees in some Sierra foothill locations. Given the continued hot weather, drink plenty of fluids, stay in air-conditioned rooms, and never leave children or pets unattended in vehicles. ~BRO

AVIATION. VFR conditions over interior NorCal the next 24 hours. Southwesterly surface wind gusts 20-25 knots possible in the vicinity of the Delta. Local southerly surface wind gusts to 20 knots in the northern Sacramento Valley possible through 06Z tonight.

STO WATCHES/WARNINGS/ADVISORIES. Excessive Heat Watch from Friday afternoon through Sunday evening for Carquinez Strait and Delta-Central Sacramento Valley- Motherlode-Mountains Southwestern Shasta County to Western Colusa County-Northeast Foothills/Sacramento Valley-Northern Sacramento Valley-Northern San Joaquin Valley-Southern Sacramento Valley.
