Our Current Weather Pattern - Variable
We are currently under the influence of an upper trough from 32 North 71 West, across Cuba to around 19 North 81 West. Then we have a surface low located over the Eastern Bahamas with a stationary front extending North Eastwards from this low. Upper level diffluence and surface forcing is generating overcast skies and possible thunderstorms from 19 North, to 32 North and between 63 West and 73 West. We fall within the approximate 240 miles band of showers and thunderstorms caused by this surface low.
Over Hispaniola, the local topography, (i.e., our mountains and terrain) is causing enchanced lift of the cloud cover. Two further surface troughs is helping to create more rain and thunderstorms on our end of this large weather pattern. San Juan Doppler radar indicates that the most organized activity is moving over Hispaniola into the deep moisture associated with the upper trough.
The weak low will be meandering around North of us through Friday, and the upper trough is expected to finally flatten by Saturday. So, this messy weather will most likely diminish by the weekend. We should see more sunshine after that.
