The First Warning Storm Team is tracking more hot and humid weather.

An isolated shower is possible this evening, but rain chances are slim. Lows tonight in the lower 70s. Watch out for areas of patchy fog tonight and tomorrow morning.

If you thought Wednesday was warm and humid, Thursday will be just the same. Highs in the upper 80s, but will feel like the lower 90s thanks to the humidity. Expect partly cloudy skies with low rain chances.

Temperatures will climb to 90 to end the work week. The humidity will make temperatures feel close to 100. We are tracking a cold front that will bring in showers and storms later Friday and into Saturday.

Tonight: Partly cloudy and sticky. Lows in the low and mid 70s. Patchy fog. Winds: E 5-10 mph.

Tomorrow: AM patchy fog. A slight chance for an isolated shower, otherwise partly cloudy (15%). Highs in the upper 80s. Winds: SE 5-10 mph.

Tomorrow night: Mostly cloudy. A slight chance for a shower. Lows in the mid 70s. Winds: S 5-10 mph.

Tropical Update

Gert is moving rapidly toward the ENE near 37 mph. An even faster motion toward the east-northeast is expected through Thursday, followed by some deceleration and a turn toward the northeast Thursday night and Friday. Maximum sustained winds are near 105 mph with higher
gusts. A weakening trend is forecast to begin Thursday morning, and Gert is likely to lose its tropical characteristics by Friday. Hurricane-force winds extend outward up to 35 miles from the center and tropical-storm-force winds extend outward up to 140 miles

Location: 40.1°N 58.4°W
Moving: ENE at 37 mph
Min pressure: 967 mb
Max sustained: 105 mph

A low pressure system located about 650 miles east of the Lesser Antilles has become a little more concentrated. Upper-level winds are forecast to become more conducive for development during the next day or so while the low moves westward at 15 to 20 mph across the tropical Atlantic Ocean, crossing into the Caribbean Sea on Friday.  Hurricane hunter aircraft is scheduled to investigate this system on Thursday, if necessary.

Formation chance through 48 hours: MEDIUM…50 percent.

Formation chance through 5 days: MEDIUM…60 percent.

Another area of low pressure is located about 950 miles west of the Cabo Verde Islands. Gradual development of this system is possible during the next few days while it moves WNW at 15 to 20 mph, but upper-level winds are expected to become less conducive for tropical cyclone formation when the disturbance moves north of the Leeward Islands this weekend.

Formation chance through 48 hours: MEDIUM…40 percent.

Formation chance through 5 days: MEDIUM…50 percent.

A tropical wave located southeast of the Cabo Verde Islands is producing disorganized showers and thunderstorms. Environmental conditions are forecast to become more conducive for development over the weekend while the system moves westward to west-northwestward at about 15 mph.

Formation chance through 48 hours: LOW…near 0 percent.

Formation chance through 5 days: MEDIUM…40 percent.
