A high pressure ridge is taking over and will dry us out. A weak frontal system will bring a few showers today into Saturday with some sunshine and then the dry weather, except for a slight chance of showers, begins. A high pressure ridge (“Arch” shape shaded and with blue arrows) is falling in behind the low and will dry us out and show us that illusive bright orb called the sun. It won’t be until the middle to the end of next week that a frontal system will move through adding to the clouds and rainy weather.
