As an upper-level trough moves eastward into our area, the surface high pressure system keeping things dry for the past couple days will be pushed out into the Atlantic and a surface cyclone will pass us to our northwest. During this transition from a high pressure to a low pressure system, a southerly/southwesterly wind will persist, bringing temperatures into the mid and upper 60s for the start of the week. Happy Halloween Seawolves!
