A week low will track through northern reaches of the CONUS and Canadian border this week yielding some upper Midwest and New England shower chances. Cold air on the backside of this system will bring some light snow showers to the Canadian Prairies. Two stronger storms are likely this weekend which are likely to bring showers and storms to the Desert Southwest and the S Plains. An addition Central US low pressure system is possible early next week. Widespread warmth is expected across the Eastern CONUS on Halloween and this weekend.
