A weak upper level low (Shaded “U” shape with blue arrows) is moving toward us as weak high pressure (Shaded “Arch” shape with blue arrows) moves away. A relatively dry cold front will move through bring cooler temperatures behind it. A peek at the future shows a cold front moving in for Mother’s Day producing another chance of showers.
