We are stuck in the same weather pattern most of the week. A Bermuda high just off the coast coupled with low pressure disturbances moving in the area from the Great Lakes along with what is termed an upper level trough (as the wind moves from the west to the east it tends to either bow down, like a feeding trough, or bow upward called a ridge) will aid in the dynamics which will allow for scattered storms. This pattern stays the same for the rest of this week. Therefore, we could see, with the heating of the days, storms forming in the afternoons. Most storm activity will fade in the evening as the heating of the day cools. Wednesday we should see more storms as a cold front moves into the area adding to the dynamics already in place. So, for the rest of this week we can expect scattered thunderstorms each afternoon. I will talk more about Wednesday later on Tuesday. These scattered storms could be slow movers and therefore dump a lot of rain. Wind and lightning will be the other major threats.
Concerning the tropics, thus far there are a couple areas of interest, but nothing close to us. One of the areas of interest, now termed Invest 99L, looks interesting as some of the early models have it moving toward the eastern seaboard, but this is way too early to talk about anything definite. But know I will be following it and will let you know if I think it is something for us to be concerned about here in MD.
