70 / 61 warm southerly and more humid flow continues as the cut low spins to our west. Dual ULL SW and into the Mid west looks like eyes on the 500 MB chart today. Scattered showers and storms later this PM and otherwise warm/humid with this flow mid - upper 80s - think the warm shots will be shy of 90 but could be close with enough sun. Sun - Fri looks unsettled with Monday /Tue the wettest days as the ULL heads east and a more E/NE onshore flow cools it down. Perhaps a break mid week on Wed before trough moves through THu/Fri and bring more clouds and rain. 6 day totals 2 - 4 inches with some spots higher. 5/ 9 and into mid month looks near normal and drier. No exceptional temp swings either way currently forecast through the 15th.
