Monday Evening Weather Headlines

  1. Hurricane Barbara upgraded but won\u2019t last very long as it reaches much cooler water, dry air, and wind shear. Tropical Storm Cosme to the WSW is in better shape and should become a Hurricane as well, minimal, Category 1, before decaying.

  2. We\u2019re stuck in an unsettled and wet pattern for the foreseeable future across the Plains and Eastern U.S. into mid-June.
