Wednesday, August 20 Forecast Discussion

Temperatures today have been able to reach the middle 90s area wide with just a pop-up storm or two out there. The little clouds and rain that are out there will dissipate after sunset, leaving us with a clear but muggy night today.

Rain chances go to virtually zero until Monday as high pressure builds in above and at the surface. Winds will be very light, offering little relief from the heat, as temperatures soar to the upper 90s for Thursday and Friday and lower 100s for Saturday and Sunday. Heat index values will exceed 100 and 105 through the weekend. You should make sure you are staying hydrated, taking plenty of breaks in the shade, and checking on children, pets, and the elderly throughout the weekend.

Relief begins to return on Monday as it looks like showers and storms could roll into the area from the east as our winds in the mid levels of the atmosphere turn easterly thanks to high pressure moving to our north. The easterly winds will also start to pump in cooler air, meaning highs drop from 100 on Sunday to 97 Monday and down to 94 by Wednesday.

In the tropics, there is a tropical wave in the Central Atlantic, east of the Lesser Antilles, that bears monitoring through the weekend. The National Hurricane Center currently gives this system a 50 percent chance to develop over the next two days and 60 percent over the next five. Because we are reaching the peak of hurricane season, a system could develop at anytime and head in any direction. Any threats to the United States would not arrive until the start of next week at the earliest. For the latest tropical information, visit our hurricane page, www.wtok.com/weather/hurricane.
