Meteorologist Myles Henderson’s First Warning Forecast

More sunshine and even cooler… If you liked yesterday’s weather, then you will enjoy today and the next few days. Expect highs in the low 80s today, actually below normal for this time of year. Dew point values will fall into the low 60s and upper 50s, very refreshing for this time of year. We will see plenty of sunshine with a few clouds blending in at times. Rain chances remain very slim.

Expect highs in the low to mid 80s for Wednesday and Thursday, with more sunshine and very slim rain chances. Highs will climb back into the upper 80s to near 90 for Friday and the weekend. As temperatures go up, so will the dew points. Heat index values will return to the upper 90s by Friday.

Today: Mostly Sunny, Cooler. Highs in the low 80s. Winds: NE 5-15

Tonight: Mainly Clear. Lows in the upper 60s. Winds: E 5-10

Tomorrow: Mostly Sunny. Highs in the low to mid 80s. Winds: NE/E 5-10

Tropical Update

Tropical Storm Gaston continues gaining strength in the eastern tropical Atlantic. Gaston is about 685 miles west of the Cabo Verde Islands and moving WNW at 21 mph. Maximum sustained winds have increased to near 65 mph with higher gusts. Additional strengthening is likely and Gaston should become a hurricane later today. As of now, Gaston is no threat to land.

Moving: WNW at 21 mph

Min pressure: 1002 mb

Fiona has weakened to a post-tropical cyclone about 430 miles south of Bermuda. The leftovers of this system will continue to drift generally NW over the next few days.

We are also watching a tropical wave located about 300 miles east of the Leeward Islands. Environmental conditions are somewhat conducive for development of this system during the next couple of days while it moves west-northwestward at 15 to 20 mph near the northern Leeward Islands and the Greater Antilles. This system will likely continue toward Hispaniola, Puerto Rico, and the southeastern and central Bahamas later this week.

* Formation chance through 48 hours: Medium (50%)

* Formation chance through 5 days: Medium (60%)
