A high pressure ridge (shaded “Arch” shape with blue arrows) is still dominating our weather pattern. A cold front has slipped through continuing the chance of rain, but Thursday will see dry weather with some sunshine. Another frontal system (position shown is Saturday) will be sliding by the high pressure that will bring the showers back through the weekend and beyond.
