Afternoon heat index values in the Heat Advisory area will range between 105 and 109 degrees. There will also be a slight chance of showers and thunderstorms region wide today.
Drier air will slowly filtered into the region from the northeast on Sunday and Monday. By Tuesday morning, moisture will begin increasing enough to support shower and thunderstorm chances, which will steadily increase as we head into Wednesday. In addition, temperatures will be on a gradual downtrend during this time frame, and high temperatures only in the upper 80s to near 90 degrees are possible by the middle of the week!
A pattern change will occur this weekend as the hot upper level high moves off to the northwest. This will bring northerly flow aloft to the region and push a cold front into the area by Saturday. The front will move through by Sunday with slightly cooler conditions with lower humidity expected behind it. There will be a low chance of rain each day from Saturday through the middle of next week.
