7/20 – Rob’s “High Heat Indices” Midday Forecast

After a rain-free and clear start to the day, heating and moisture flow has triggered a few clouds along the coastal counties.

High-pressure through the interior will remain in place for the next few days causing heat levels to remain high especially over the central portion of the nation. This will help cause a noticeable decrease in showers/t-storms coverage through Friday, but will also cause an increase in temps and Heat Index values through Friday.

Oppressive heat is expected to affect the area but should remain just under heat advisory criteria, although a few isolated
locations could actually reach 108 degrees with no cloud cover. Thunderstorms numbers will be at a minimum through at least Friday…increasing for the weekend as temps drop back to around 90 degrees. An upper low-pressure system will retrograde from the South Carolina/Georgia coast and begin to affect this area Friday night into Saturday. By Sunday, rain chances fall back to normal levels for this time of year.
