Springfield, Mo. – Dangerous heat will grip much of southwest Missouri through Tuesday, with heat index values climbing as high as 110 degrees while isolated afternoon thunderstorms offer little relief from the oppressive conditions.
According to the National Weather Service in Springfield, a Heat Advisory remains in effect from 1 p.m. Monday until 7 p.m. Tuesday for much of southwest and central Missouri. Afternoon heat index values are expected to range from 100 to 110 degrees, creating an elevated risk of heat exhaustion and heat stroke for anyone spending extended time outdoors.
Communities including Springfield, Joplin, Branson, Lebanon, Rolla, West Plains, Nevada, Clinton, Pittsburg and surrounding areas will see afternoon highs generally ranging from the upper 80s to lower 100s, with overnight lows only falling into the mid-60s to upper 70s, limiting overnight cooling.
According to the National Weather Service, daily afternoon thunderstorm chances of 15% to 30% are expected Monday and Tuesday. While storms will be scattered and many communities will remain dry, any thunderstorm that develops could produce brief heavy rainfall, gusty winds and dangerous cloud-to-ground lightning.
Residents should drink plenty of water, wear lightweight clothing and limit strenuous outdoor activities during the hottest part of the day. Frequent breaks in air-conditioned locations are recommended, and children or pets should never be left unattended inside parked vehicles.
The hottest conditions are expected Tuesday before temperatures gradually begin to ease later in the week. Additional heat-related alerts could be issued if the dangerous heat persists or expands across southern Missouri.
