Meteorologist Myles Henderson’s First Warning Forecast

Sunny and cooler… Get ready for a beautiful stretch of weather this week. The cold front that brought us the showers and storms last night is moving out. We could see a few leftover clouds this morning but expect sunshine for most of today. Cooler and less humid air is moving in behind the front. Expect highs in the mid 80s today, near normal and about 10 degrees cooler than yesterday. It will also be breezy with north and northeast winds at 10 to 15 mph.

Sunshine continues for midweek with even cooler and drier air moving in. Expect highs in the low 80s for Tuesday and Wednesday, with dew points in the low 60s. Rain chances will remain low with only a stray 10% chance in the mix. Highs will climb back into the upper 80s to near 90 to end the work week and start the weekend.

Today: Mostly Sunny, Cooler, Breezy. Highs in the mid 80s. Winds: N/NE 5-15

Tonight: Mainly Clear. Lows in the mid 70s. Winds: NE 5-10

Tomorrow: Mostly Sunny, Cooler, Breezy. Highs in the low 80s. Winds: NE/E 5-15

Tropical Update

Fiona weakens to a tropical depression. Fiona is located about 525 miles NE of the northern Leeward Islands and about 670 miles SE of Bermuda. Fiona is moving WNW 18 mph and will continue that motion with a gradual decrease in forward speed today and tomorrow. Maximum sustained winds have decreased to near 35 mph with higher gusts. Little change in strength is forecast during the next 48 hours, but Fiona could become a post-tropical remnant low in the next day or two.

5:00 AM AST Mon Aug 22

Location: 24.4°N 58.4°W

Moving: WNW at 18 mph

Min pressure: 1008 mb

Max sustained: 35 mph

We are also watching two other systems in the Atlantic…

  1. A tropical wave located about 900 miles east of the Lesser Antilles. Dry air near this system is expected to limit significant development during the next few days while the disturbance moves westward to west-northwestward at 15 to 20 mph. Environmental conditions could become more conducive for development late this week when the system is moves closer to Hispaniola and the Bahamas.

* Formation chance through 48 hours: Low (10%)

* Formation chance through 5 days: Medium (40%)

  1. Thunderstorm activity continues to show signs of organization in association with a tropical wave and a large area of low pressure located almost 300 miles south of the southern Cabo Verde Islands.

Environmental conditions are conducive for development, and a tropical depression is likely to form later today while the system moves westward at 15 to 20 mph over the eastern tropical Atlantic.

* Formation chance through 48 hours: High (90%)

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