Only northern Arkansas is under a marginal risk (level 1 of 5) of severe weather today. The primary concern with any thunderstorm will be strong gusty winds. Some of the stronger storms could produce heavy rain leading to localized flooding.
The weather pattern will be undergoing a change starting as early as Sunday. Upper level high pressure will be building over the area and dominating through the week. This pattern promises to bring hot and humid conditions to the state with little if any chance of precipitation.
Upper level high pressure will begin to build over the region this week and become the dominant weather feature through next week. The forecast is calling for hot and humid conditions with heat index values over the century mark for many parts of the state.
Here is a look at the maximum heat indices expected this weekend. While it will be hot out there, especially Sunday, these values will likely be even higher next week.
Dangerous heat will be building over the region this week and now would be a good time to remember that the temperature inside a car with closed windows can become deadly in a short amount of time. Remember, beat the heat, check the back seat!
