Saturday August 22 2020
There is a lot to cover in this morning report and I wanted to simplify it for you. We have had local rain and the short range modeling has not been doing a good job handling it. Showers and storms will be scattered today and Sunday, but I will elaborate on that below.
The major weather story is the two Tropical Storms that are both expected to be in the Gulf of Mexico early next week. This would be only the third time on record. There has been a shift in the tracks and timing. This will not impact us, but it is worth following for national and scientific interests. Check out the wind forecast including both storms. The updates and forecasts for each storm are below.
Tropical Storm Winds: Laura AND Marco
Local Weather
Rain has been falling this morning in southern Maryland and some showers have lingered. The short rang models have missed a lot of the activity, so we need to extrapolate and anticipate at least the chance for showers across parts of central Maryland this afternoon.
Stronger storms may turn severe in the mountains later today.
Sunday, the best chance for storms will be in the late afternoon and evening.
Temperature Forecast This Weekend
It will feel warmer and more humid.
Temperature Outlook
Tropical Storms Update
As of this morning, these are both minimal storms. T.S. Laura has 40 mph, T.S. Marco has 45 mph winds. Both are expected to intensity when reaching the Gulf of Mexico after the weekend.

Tropical Storm Laura
This track has shifted south, taking it across the Northern Caribbean Islands. This will limit is growth potential until passing Cuba and entering the Gulf on Monday night. This is now expected to pass well south of Florida, but they will get some rain on The Keys.

Tropical Storm Marco
This storm is now expected to short north and just clip Cancun. This will allow it to grow more rapidly than Laura. It will enter the Gulf of Mexico first, and track farther west. The curve on Monday is expected in part as a response to Laura. Two tropical systems will NOT merge, but they can repel or orbit around each other. It’s called the Fujiwara Effect.
