Good afternoon, We wanted to send a quick briefing to highlight a dangerously cold airmass which is expected late Friday into Saturday across southern New England. Wind chills are expected to drop to -20 to -40F late Friday night and Saturday morning. In addition, widespread moderate to heavy freezing spray is expected on the coastal waters with gale force winds. Thanks.
