Over the last week, the southeast has enjoyed near-normal temperatures; however, as you probably have noticed, we began to heat up over the last couple of days. This trend will continue throughout this upcoming week as the Texas ridge of high pressure strengthens and wobbles eastward. This pattern will result in abnormally high temperatures, especially in the western sections of the Southeast.
850mb temperature anomalies show that the lower atmosphere is projected to be well above the average temperature for this time of year. This heat will transfer to the surface as locations from Kentucky to Louisiana warm up. This surge of warmth is expected to takeover in most of the region by the middle of the week. The Weather Prediction Center shows a possibility of heat indices reaching heat advisory criteria for many locations along the lower and middle Mississippi River Valley regions.
The strong ridge of high pressure over Texas will keep temperatures in the western portions of the southeast above average for several days. The Climate Prediction Center indicates that, in the next 14 days, the high pressure system will stay over the south central US. Because the system has strengthened, its influence will stretch across the southeast as well as most of the country. As a result, communities from the Carolinas to the Mississippi River will see some variation of a warmup.
Today, there is a slight risk (2-out-of-4) of excessive rainfall for parts of Kentucky and the middle Mississippi River Valley. As that high pressure system strengthens, however, future rainfall estimates in the Southeast look to be below average over the next week and a half. Looking further into the future, signals indicate that the western half of the region will have slightly below average rainfall while precipitation may be slightly above average in the eastern portions of the region.
