A high pressure ridge (shaded “arch” shape) is taking over and will dry us out as the trough of low pressure (shaded “U ” shape) pulls farther away from us. A weak frontal system is sliding down from the north along the the ridge. It won’t be until the end of the week that another frontal system will move south of us spreading some clouds and rainy weather at us.
