6/26 – Rob Knight’s “Hot/Humid, Summertime” Forecast
Summertime conditions continue across the forecast area. In the upper portions of the atmosphere, a weak ridge of high-pressure is trying to maintain its position over the southeastern states while a trough moves through the upper Mississippi Valley. Expect high temps maxing out in the lower/mid 90s, with scattered showers and thunderstorms.
The resultant heat indices should mainly be in the 100 to 105 range. This falls below heat advisory criteria of 108+, so will not issue one for today.
The remainder of this week will basically be the same each day with highs in the lower 90s, heat indices right at to just below heat advisory criteria, and scattered afternoon t-storms. It will be a day to day decision on the need for an advisory. Moving into the weekend, an upper ridge currently near the desert southwest will track across the midsection of the country this week. As it makes its way towards the Appalachian Mountains, the local area will be in less of a subsidence region. This should allow for noticeable uptick in sjowers/t-storms and a drop in max temps.
