An upper level high pressure ridge (Shaded “Arch”shape with blue arrows) has taken control of our weather producing warmer offshore airflow. Look for plenty of sunshine and warmer temperatures today and Thursday. We have the potential of reaching 86 degrees or more for high temperatures today and Thursday. Upper level Low Pressure (Shaded “Oval” shape, then “U” shape) will replace the high pressure and return the much cooler onshore airflow. By Friday night into Saturday a weak frontal system will return the slight chance for showers.
