Meteorologist April Loveland's First Warning Forecast

Excessive Heat Warning in effect from 11 AM to 8 PM Thursday for Pasquotank, Camden, Western Currituck, Chowan and Perquimans Counties. Dangerously hot conditions with heat index values up to 113 expected.

Heat Advisory in effect from 11 AM to 8 PM Thursday for Gloucester, Middlesex, Mathews, Surry, James City, Williamsburg, York, Hampton, Poquoson, Surry, Sussex, Isle of Wight, Southampton, Suffolk, Franklin, Chesapeake, Virginia Beach, Norfolk, Portsmouth, Northampton (NC), Hertford, Gates, Bertie and Dare. Heat index values up to 109 expected.

Heat and humidity continue to build on Thursday. This will be the hottest day of the week. Expect dangerous heat throughout the day with highs well into the 90s and heat index values 105 to 113. We will continue with a chance for some scattered showers and storms. Any storms that form have the chance to become strong to severe. The Storm Prediction Center has northern portions of the viewing area in a level 1, which means isolated severe storms are possible. Northern portions of the Eastern Shore are under a level 2, which means scattered severe storms are possible. The biggest threat will be damaging wind gusts. The threat for tornadoes will be greatest to the north of I-64. North of our viewing area will have the best ingredients to see severe weather late Thursday into Thursday night.

A cold front will move through on Friday. It will still be hot and humid with highs in the 90s. Scattered showers and storms will be possible once again by the late afternoon and evening.

Once the cold front moves through, we will get to enjoy a comfortable start to the holiday weekend. Saturday will feature lower humidity and highs in the low 80s along with plenty of sunshine. Sunday will also be comfortable with highs in the low 80s.

Temperatures will start to trend a bit warmer on Labor Day. Expect highs in the mid 80s under partly cloudy skies.

Tropical Update:

Nana has become a hurricane and is expected to make landfall along the coast of Belize overnight.

Currently located about 60 miles SE of Belize City.

Nana is moving toward the west near 16 mph, and a westward or west-southwestward motion is expected tonight and Thursday. On the forecast track, Nana will make landfall along the coast of Belize within the Hurricane Warning area overnight, and move inland over Belize and Guatemala on Thursday. Maximum sustained winds have increased to near 75 mph with higher gusts. Little additional change in strength is expected before Nana makes landfall. Rapid weakening is expected on Thursday as Nana moves farther inland. Nana is a small hurricane. Hurricane-force winds extend outward up to 10 miles from the center and tropical-storm-force winds extend outward up to 70 miles.

Tropical Depression Omar is moving toward the east near 13 mph, and this general motion is expected to continue through Friday. A turn toward the east-northeast with some reduction in forward speed is forecast on Saturday. Maximum sustained winds are near 35 mph with higher gusts. Further weakening is forecast, and Omar is likely to become a remnant low Thursday and dissipate by Saturday night.
