A few scattered showers are possible overnight as the weak shear-line lingers across our islands with the Atlantic High Pressure System weakly maintained. Slight hazy conditions should be clearing by Monday as Tropical Storm Dorian approaches the island chain. Ahead of the Tropical Storm Dorian, lower level moisture/cloud patches could result in a few scattered showers from Sunday.
Cloudy to overcast skies, with pockets of moderate to heavy showers, periods of rain and thunderstorm activity with occasional gusty winds can be expected across our area by late Monday into Tuesday. Instability could linger on Wednesday with upper-level features enhancing shower activity.
