MEMPHIS - We'll dive back into the 90s this afternoon, couple that with rising humidity it's safe to say 'summer is back!' An area of high pressure in the upper levels of the atmosphere will drive up the heat today while keeping storm chances low. The air under an area of high pressure sinks; when air sinks, it compresses and warms. On that same note, thunderstorms need to be able to rise to form and when air is sinking, storm formation is very limited. That doesn't mean it won't rain this afternoon but storm coverage will be isolated. Dew points have risen into the low 70s; some call that oppressive pushing the heat index near or above 100°. The heat and humidity stay cranked through Wednesday before a cool front slides across the Midsouth. This front will spark scattered showers and thunderstorms Wednesday and Thursday; the set up does pose a threat for a few severe storms, stay tuned. The front will be east of us Friday; by then highs will be back in the 80s and the mega humidity will be gone as well.
Have a great week!
