Meteorologist Myles Henderson’s First Warning Forecast

Heat, humidity, and a severe threat… Highs will climb to the low and mid 90s this afternoon, almost 10 degrees above normal for this time of year. With the humidity, it will feel more like the upper 90s to low triple digits. Clouds will continue to clear out this morning and most of today will be sunny. Strong to severe storms are possible this evening and tonight. The biggest threat will be on the Middle Peninsula, Northern Neck, and Eastern Shore.

Wednesday will be the most comfortable day of the week. Temperatures will dip to the upper 80s with lower humidity. Sunshine will return tomorrow, and rain chances will be slim.

Heat and humidity will ramp up for the end of the work week. Highs will climb to the low and mid 90s with afternoon heat index values in the triple digits. We will see a nice mix of sun and clouds with an isolated shower/storm possible.

The biggest rain chance this week is set for Saturday. The leftovers of Tropical Storm Laura will be pushed over the Mid-Atlantic by a cold front. The biggest chance for rain and storms will be Saturday night. Winds will also pick up, SW 10-20 with gusts to 30 mph.

Tropical Update

Hurricane and Storm Surge Warnings issued for parts of the Gulf Coast. Hurricane Laura is centered about 585 miles SE of Lake Charles, Louisiana and moving WNW at 16 mph. On the forecast track, the center of Laura will move across the southeastern Gulf of Mexico today. Laura is then forecast to move over the central and northwestern Gulf of Mexico tonight and Wednesday, approach the Upper Texas and Southwest Louisiana coasts on Wednesday night and move inland near those area on Thursday.

Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 75 mph with higher gusts. Significant strengthening is forecast during the next 36 hours, and Laura is expected to be a major hurricane at landfall.

Marco is a remnant low just south of Louisiana and moving west. Marco should continue moving west just offshore the coast of Louisiana until the system dissipates.
