Issued at 1001 PM EDT Wed Apr 2 2025 A strong surface pressure ridge that extends along the Atlantic Coast and westward across the Gulf is generating fresh east to southeasterly breezes across the forecast area this evening. The breezy conditions is pumping in relatively warm and humid air with temperature still near 80 and dew points in the mid 70s. Meanwhile, strengthening deep layered ridging stretches north and northeastward across our area. This evenings sounding indicated a modest 1.15 inches of precipitable water with a good amount of lower level inhibition. Surprisingly, this inhibition begins rather low at around 950 mb. As a result, shower activity has been very limited. The tight pressure gradient will persist through the night and will maintain the breezy to windy conditions. This flow will hamper night time cooling. As a result, expect overnight lows to hold in the upper 70s, while dew points may slip a couple degrees in to the lower 70s. Forecast sounding suggest the lower level inhibition will weaken. However, moisture and instability will remain limited, and lower level lift will be weak at best. As a result, while a shower or two cannot be absolutely ruled out, rain chances will be slim. && .MARINE...
