The overnight NAM model gives G.R. a high of 79° today (Weds.) and a 2 pm temp. of 50° on Thurs. The GFS has high temps. no warmer than the mid 50s from Thursday thru Weds. of next week.
Cold air coming over (relatively) warm water makes for bigger waves. Small Craft Advisories are in effect from 2 pm to 10 pm today – then we go to Gale Warnings through early Thursday. Waves should eventually reach 5-8 feet.
BOTH the GFS and the NAM give G.R. a 100% chance of rain today – esp. between 2 pm and 8 pm.
