Still near 10º above average each day with a consistent chance at showers and storms

-- Each day will be partly cloudy to mostly sunny.  Consistent chances for showers and storms across the area will manifest themselves in the early afternoon and early evening.

Thursday:  High near 85 with a low around 65.
Friday:  High near 88 with a low around 68.
Saturday:  High near 91 with a low around 69.
Sunday:  High near 91 with a low around 69.

The summertime weather pattern that has set up in the southeast won't be changing this weekend, with persistent southerly/southwesterly flow continually advecting warm air and additional moisture from the Gulf of Mexico. Several areas of vorticity appear to be rounding the ridge this weekend, especially more potent one late Thursday afternoon and evening.  As these coincide with daytime heating, some strong and potentially severe thunderstorms cannot be ruled out of the forecast.

Finally, by Sunday, a frontal boundary will approach the Ohio River from the north and become quasi-stationary, blocked by high pressure over most of the Atlantic.  For now, it doesn't look as though any break from the well-above average temperatures will come until Wednesday or Thursday next week.

A look at next Wednesday's forecast shows a cold front draped from the Huntington, WV area southwestward toward southern AR.  Until then, we'll be much warmer than normal for early May.
