Strong high pressure over the southwest will lead to hot temperatures across the region through the week. Temperatures will be 10 to 20 degrees above normal, peaking today through Thursday. Santa Maria's hottest day is expected tomorrow, while Santa Barbara's was today. Gusty north winds will affect southern Santa Barbara County today leading to critical fire weather conditions. A cooling trend is expected to begin by Saturday and continue into early next week.
Heat wave has arrived. Temperatures along the coast on Tuesday were in the 80s and 90s and inland spots were in the triple digits to high 90s.
Hot, dry and windy conditions have prompted a red flag warning along with a wind advisory for the Santa Barbara South Coast and county mountains through Wednesday early morning.
Excessive Heat Warning for mountains and valleys continues until Friday night. The excessive heat warning for the Central Coast will continue until 9PM Wednesday night.
Excessive heat warning for coastal areas south of Point Conception expires as we will see several degrees of cooling Wednesday as a weak eddy circulation develops and onshore flow increases.
Warm winds along the Central Coast should actually increase temperatures there, and in some spots they could hit the triple digits.
Increasing onshore flow and slowly weakening high pressure aloft will start the cooling trend over the weekend into early next week. Temperatures still above normal but only by 5-10 degrees or so with the biggest anomalies in the interior valleys. Marine layer stratus will become more widespread along the coast but likely staying out of the valleys through the weekend.
Cooling trend to continue Monday and Tuesday.
