A large area of cold high pressure is building eastward from the Great Lakes into New England today. This fair weather center will ensure us a couple of days of dry, with our next shot at storminess not coming until Wednesday night and Thursday morning.
The surface analysis this morning tells the story well. You can see the large high pressure area located over the Ohio Valley and Lower Great Lakes and cold temperatures extending from New England westward to the Northern Rockies.
As for us here on the Cape, readings in the upper 10s and lower 20s this morning will only top out in the upper 20s to around 30F this afternoon…which is a solid 10F below the average for the date (the average high at Hyannis on February 19th is 41F). Temperatures will fall back into the 10s tonight and will once again struggle to reach 30F tomorrow.
