July 28, 2020 – Hot and dry weather continues across the region for the next week. A few thunderstorms will be possible late today across the mountains to the north of Redding.
Discussion
Clear skies cover interior NorCal early this morning as the blow off from yesterday’s thunderstorms is moving north and dissipating. Satellite imagery shows extensive stratus along the coast, but profiler data indicates its depth is only around 1500 ft, enough to continue a moderate Delta Breeze. Current temps are a little cooler across most of the area compared to 24 hours ago and generally range from the mid 40s in the colder mountain valleys to the upper 70s across the north end of the Sacramento Valley.
Not a whole lot of change in the weather is expected across the region over the next several days as the hot and dry pattern persists. The weak trough that has been lingering along the coast the past several days will be displaced by high pressure extending up from the Desert Southwest. Temperatures will be near to slightly above average for mid-summer.
Less thunderstorm activity is expected today as chances will mainly shift north of the region, though a few late day storms may pop over the mountains north of Redding. Dry southwest flow expected the remainder of the week.
Extended Discussion (Saturday through Tuesday)
The synpotic setup by this weekend will feature a high amplitude ridge over the Desert Southwest with an upper level low in the Gulf of Alaska. Central and northern California will be in the middle with dry, southwest flow aloft.
The National Blend of Models advertises high temperatures in the middle 90s to low 100s across the Sacramento Valley, or within several degrees of early August climatological normals. Onshore flow will continue with the occasional breezes impacting locations around the Delta. No precipitation is forecast in the extended.
