August 22, 2019 – Above average temperatures are expected into next week. Dry weather pattern continues.
Latest satellite imagery indicates high clouds spreading SEwd across interior NorCal as upper level trough moves through the PacNW. Therefore, cloud cover has kept current temperatures generally 5 to 15 degrees warmer than 24 hours ago.
Above normal temperatures are expected through the forecast period as the upper trough exits the region, and strong high pressure builds over NorCal.
Northerly winds will develop behind the trough, boosting high temperatures a degree or two compared to yesterday’s readings.
Valley locations should see temperatures in the mid 90s to around 104, while highs in the low 70s to mid 80s are expected over the mountains. These forecast highs will range from 5 to 10 degrees above normal. Overnight lows will provide some relief from the hot daytime temperatures, with Valley readings in the 60s.
Extended Discussion (Monday through Thursday)
Upper high extends NW from the Desert SW over interior NorCal as EPAC high extends inland. Weak upper low lifts from the SW over NorCal Wednesday into Thursday. This will result in gradual downward trend in high temperatures, but continued above normal temperatures with triple digit heat in the Northern Sacramento Valley and upper 90s elsewhere in the Central Valley. Dry weather forecast through the extended period.
