Weather Alert Day: Dangerous heat expected Tuesday and Wednesday
LINCOLN, Neb. (KOLN) - Dangerous heat is expected across much of the state over the next several days as a dome of high pressure aloft will strengthen over the area which will send actual air temperatures into the mid and upper 90s and lower 100s. Those temperatures are numbers we’ve already seen this year, but combined with dew points ranging from the mid 60s to the mid 70s, heat index values will be extremely high Tuesday, Wednesday, and even into Thursday afternoon across much of the state as they could reach between 100° and 110° at times. Heat Advisories are in place across much of the state beginning at 12 PM on Tuesday and lasting for several days. For Lincoln and southeastern Nebraska, it is in place from 12 PM Tuesday to 9 PM Thursday with the Heat Advisory ending at 9 PM Wednesday for northeastern Nebraska and across central and western Nebraska as well.
Afternoon highs on Tuesday should reach the mid to upper 90s for most of the state with some triple digit heat across northern and western sections of the state possible. With dew points reaching the mid 60s to mid 70s, heat index values by the afternoon will reach the mid and upper 90s to lower 100s for the western half of the state and between 100° and 110° for the eastern half of the state.
Wednesday should see similar conditions with afternoon highs into the mid and upper 90s with some temperatures reaching between 100° and 105° across western Nebraska. Heat index values again will be well into the triple digits for much of the state, with the most oppressive conditions expected across the eastern third of the state where heat index values could reach as high as 115° at times.
With temperatures and feels like temperatures this hot, it is even more important to make sure you are taking care of yourself if you have to spend any extended amount of time outside. Make sure to take breaks inside in the air conditioning, drink plenty of water, and make sure you’re wearing proper clothing like long-sleeve and light colored clothes. Heat stroke and heat exhaustion can set in very quickly in conditions like we are expecting, so make sure to take the heat seriously - on average, heat kills more people every year than any other weather related phenomena!
Along with the blistering heat and humidity, we should see hazy sunshine through the day on Tuesday with mainly dry weather across the state. We could see some patchy morning fog and perhaps some fair weather cumulus into the afternoon with how hot and humid it is expected to be, but other than that we should just be dealing with some hazy sunshine.
Thursday will remain very hot and humid for southeastern Nebraska, but the extended forecast does offer us some relief from the heat late this week and into the weekend as a cool front will slip through the area Thursday and into Friday which should help cool back temperatures into the upper 80s with some scattered rain chances. Those rain chances look to hang around the forecast into the weekend and early next week as the ridge breaks down and several upper level disturbances move through the area.
