An upper level trough of low pressure (Shaded “U” shape with blue arrows) moved to the east giving us a short break from the showers today as weak high pressure (shaded “Arch” shape with blue arrows) tried to take over for today at least. Another low will follow closely behind increasing onshore airflow bringing more clouds and increased chances for rain for Friday.
