After record setting heat across the Ozarks this afternoon, it will remain very warm and muggy as we head into the evening. A few storms could pop up through early evening but anything that does manage to develop will quickly die out after sunset. Overnight temperatures will only fall into the upper 60s for most locations.
Memorial day will be another sunny and hot day for the entire region and once again, some records could be tied or broken with highs reaching the low 90s. Drier air in the mid and upper levels of the atmosphere means that storm chances will be very slim with most places staying dry.
By Tuesday, the remnants of Tropical Storm Alberto will be just east of the Ozarks. Moisture rotating around the system will push west into Missouri and set the stage for a better chance of scattered thunderstorms during the afternoon. With more cloud cover, temperatures will cool slighty into the upper 80s but humidity will be very high making it feel uncomfortable.
Wednesday into Thursday will feature a northwest flow aloft with a ridge of high pressure to our southwest. With plenty of moisture still around and a series of disturbances moving through, this will set the stage for more active weather with a few rounds of thunderstorms possible. Instability will be quite high so there will be the possibility of some severe weather both days.
Beyond this time, forecast models build a very strong ridge of high pressure across the central plains and this could bring the hottest temperatures of the season so far. Highs by the end of the week and into the weekend will soar into the mid 90s with heat indices potentially in the triple digits!
