May 18 tropical storm arthur Visible Satellite Monday evening

 

Tropical Storm Arthur has reached winds of 50 mph and is now moving away from the eastern US coast. This is the closest pass by Ocean City, MD and they were hit pretty hard today with wind and rain earlier today. But gusts didn’t get much over 30 mph.

I just wanted to share the satellite images of this first named storm of the season in frame but safely at a distance. The latest info and forecast maps are below.

Maryland and East Coast Weather

We are in the ambiguous zone between the Tropical Storm and slow moving upper level storm in the MidWest. This is what has made our forecast difficult this week.  We get the clouds and cooler easterly winds, but that is also stalling the other storm to our west.

We may end up cloudy and cooler (in the 60s), but little to no rain until Friday.

Tropical Storm Arthur Computer Models

There is forcing that will curve Arthur down to the south, but it should deteriorate and not return to the coast.

Ocean Wave Model Timeline

A persistent easterly flow in the 20 to 25 knot range should last much of the week. This is what will keep temperatures cooler the average/normal.
