July 9, 2020 – Dry weather with seasonably hot temperatures for the next week.
Discussion
Clear skies cover the region early this morning. The Delta Breeze is a bit stronger early this morning compared to early Wednesday, and current temperatures are running a bit cooler compared to 24 hours ago where its influence is present. Elsewhere, current temps are running slightly warmer compared to yesterday.
Hot and dry weather will continue across the region through the upcoming weekend. Temperatures will remain a little above average today and Friday, then warm a bit over the weekend as ridging over the Southwest extends slightly north and westward.
Highs over the weekend are forecast to be around 5-10 degrees above average with much of the Central Valley in the 100 to 105 range beginning Saturday and continuing into early next week. At least a trickle of a Delta Breeze is expected to continue over the weekend which will help overnight lows in the valley to make it down into mostly the 60s to lower 70s. Heat risk looks like it will stay mostly in the low to moderate category into early next week.
Extended Discussion (Monday through Thursday)
Upper level troughing will remain in place over the PacNW for the extended period with upper level ridging over the four corners region. This will bring zonal to slight troughing over NorCal and keep a quiet weather pattern in place. Highs will be warm running 5 to 10 above normal for the start of the period but will fall to near normal by the end of next week as more troughing builds over the west coast. Some light north winds are expected Tuesday, otherwise we will see light onshore flow except through the Delta where gustier winds are expected.
