WEATHER ALERT DAY: Dangerous heat index values likely Through Saturday
UPDATE:
Our ABC 17 Stormtrack Weather Alert Day has been extended to include Saturday as heat will build ahead of a cold front that pushes through the region over the course of the day.
Storms will also be forecast for Saturday, with some potential for strong to severe storms, but the overall threat is low.
SETUP:
Upper level high pressure has been creating stifling conditions for the folks in the west for the last few weeks, but now as the feature that is acting as a "heat dome" is inching closer to mid-Missouri. We can't totally blame our heat on this upper level high pressure though, as low level winds from the south are helping bring in warm air as well. Still, this upper level high will aid in supplying warmth to us on the fringe of it's influence, and will help to block any large upper level features from the north west, although some small disturbances may bring limited chances for rain.
The combination of warmer than normal temperatures and humid to tropical dew points at times will create potential for heat index values in the 100-110 degree range.
TIMING:
The National Weather Service has continued a heat advisory for Mid-Missouri through Saturday as heat could last through the afternoon for areas that remain dry. This alert time frame will begin at 11 am, or midday Thursday, and last through Friday at 9 p.m.
IMPACTS:
Heat-related illness will be the main concern. At a heat index of 105 degrees, all people are serious risk of heat-related illness with prolonged exposure.
Heat related illness can sneak up on you, know how to protect yourself, and understand the signs to watch out for.
All people should stay inside if possible, and take steps to keep themselves cool if outdoor activity is a must.
Heat stroke and Heat exhaustion are two different illnesses, and have varying degrees of severity. If a person has a throbbing headache, aren't sweating, have a high fever, dry and red skin, a rapid pulse, nausea or unconsciousness, they may have heat stroke and 911 needs to be called.
