Temperatures will dip into the low and mid 70s overnight. It will be rather muggy. We could see a little bit of patchy fog to start the day on Friday.

Friday will be another hot one. Highs will soar to the upper 80s. Some 90s could mix in. We could see a shower or storm in the afternoon as a cold front approaches from the north. This will be a slow moving front.

Rain chances will continue for the weekend as the front lingers over the region. We will see partly to mostly cloudy skies with on and off showers and storms through the weekend. The northern portions of the viewing area will have the best chance to see showers and storms on Saturday. Highs will drop into the low 80s for the weekend but it will still be muggy. We are giving both Saturday and Sunday a 60 percent chance for some showers and storms.

Temperatures will warm back to the mid and upper 80s Monday through Thursday. A chance for some scattered showers and storms on Monday and Tuesday. Looking drier on Wednesday and Thursday with partly cloudy skies.

We are tracking a broad area of low pressure 500 miles WSW of the Cabo Verde Islands is gradually becoming better defined, although the associated shower and thunderstorm activity has not yet increased much in organization.  Environmental conditions are conducive for further development, and a tropical depression is expected to form within the next day or two while the system moves slowly westward across the tropical Atlantic Ocean.

* Formation chance through 48 hours: High (80%).

* Formation chance through 5 days: High (90%).

A tropical wave and an accompanying low pressure system near the west coast of Africa is producing a large area of thunderstorms. Environmental conditions appear conducive for development, and a tropical depression or tropical storm is likely to form over the weekend while the wave moves westward or west-northwestward over the far eastern tropical Atlantic Ocean. Interests in the Cabo Verde Islands should monitor the progress of this system, and potential tropical cyclone advisories could be issued on Friday.

* Formation chance through 48 hours: High (70%).

* Formation chance through 5 days: High (90%).
