Southwesterly surface winds, fairly dry air and sunshine will make for unseasonably hot conditions Sunday with highs in the mid to upper 90s.
This will be followed by a significant cool-down as a front drives through Texoma Monday.
Lows should return to the 50s for Tuesday and Wednesday morning with daytime highs around 80. Nice!
Southerly wind brings back surface moisture beginning Wednesday; the next rain chance comes with a slow-moving upper low and surface cold front late in the week.
