LITTLE ROCK — Little Rock registered its hottest day so far this year Sunday when the official temperature at the citys airport climbed to 106 degrees Fahrenheit, prompting an Arkansas Storm Team Alert Day and raising concerns about heat-related illness and wildfire conditions across the region.
Storms arrive with weak cold front
Thunderstorms developed across parts of central and northern Arkansas Sunday afternoon and evening as a weak cold front moved into the state. Meteorologists reported a possible microburst near Pinnacle Mountain in Pulaski County at roughly 3:45 p.m. CDT. While showers and storms will continue to pop up into the overnight hours, forecasters say coverage will be scattered and not everyone will see rain.
Heat to linger for much of the week
With the region's persistent high pressure beginning to break down, the immediate effect is an increase in daily rain chances, but it does not translate into prompt relief from the heat. Forecasters expect Little Rock to remain at or near triple-digit temperatures through the latter part of the week. Northern Arkansas is likely to see highs drop into the 90s on Monday, Aug. 17, behind the weak front, but southern Arkansas may not see that same easing.
By the end of the work week, another frontal passage is expected to push more widely through the state and bring highs down into the 90s by next weekend, according to the Arkansas Storm Team guidance.
Wildfire danger remains despite rain chances
Even though showers and storms will be more common this week, fire officials and meteorologists caution that wildfire risk persists. Brief, high-intensity storms and downburst winds can complicate firefighting efforts and spark new blazes in dry, fuel-rich areas. The Storm Team noted that the elevated fire danger continues alongside the heat and storm pattern.
- Sunday high (Little Rock airport): 106°F
- Notable event: Possible microburst near Pinnacle Mountain, Pulaski County, ~3:45 p.m. CDT
- Short-term trend: More daily rain chances; triple-digit heat likely to persist in Little Rock through late week
- Later trend: Cold front expected to lower highs into the 90s by next weekend
What residents should know and do
Health and safety officials typically advise these precautions during prolonged extreme heat and scattered storm events:
- Limit outdoor exertion during the hottest parts of the day and seek air-conditioned shelter when possible.
- Stay hydrated and check on vulnerable neighbors, including the elderly and those with chronic health conditions.
- Prepare for sudden storms: secure loose outdoor items and be ready for brief periods of strong wind.
- Be cautious with fire sources and heed local restrictions; even with rain chances, fuels remain dry in many areas.
The Arkansas Storm Team encourages residents to download their app for the latest updates, interactive radar and alerts for severe weather and heat advisories.
Local impacts and outlook
Travel, outdoor work and recreational plans may be affected this week both by heat and by the possibility of localized storms. While scattered showers could offer short-lived relief in some communities, the combination of sustained high temperatures and lingering dry fuels means the statewide wildfire outlook remains a concern until a more substantial and sustained pattern change arrives.

|---|---|
| Sunday | Hottest day at 106°F; scattered storms and possible microburst |
| MondayThursday | Daily rain chances; Little Rock likely still at/near triple digits through late week |
