    Lots of warm moist Gulf air lifts north today into the weekend. Convective storms may breakout further south later today. Fragmented showers & storms will spread north into North/Central West Virginia & the higher elevations Saturday & again Sunday afternoon/evening. Warmer temperatures and higher humidity will make a comeback over the weekend. Heat indices will eventually reach the mid/upper 90s next week. Weak cold front may bring a few chance showers Tuesday next week.

    For today, not much chance for thunder across much of our coverage area. Only exception is along southwestern portions of our state, due to slightly higher temps & more upper level moisture. Elsewhere, mostly sunny skies & highs in the low/mid 80s make for a pleasant end to the work week. Increasing cloud cover may hinder the lighting effects of a full moon. Otherwise, conditions remain cool & calm overnight with lows in the mid to upper 50s.

    Temperatures & humidity will be on the increase Saturday as more warm, moist air lifts north. Upper level instability increases with daytime heating. Chance for showers and storms will spread north, into Central West Virginia & into the mountain counties Saturday evening & again on Sunday. Considering the near-saturated air, any weekend storms-although short-lived, could dump heavy amounts of rain. The way these humid, summer-time systems go, much of our forecast area may skate through the weekend on a dry note. Again, best chances for precip will be further south.

    Mercury will continue to rise Sunday, Monday and through next week. Dew points will stay in the upper 60s/low 70s. This hints at heat indices beyond the mid & upper 90s by midweek. Tuesday, a weak cold front will head east across the southern Great Lakes, weakening as it crosses the Ohio River Valley. We may see a few pop up showers Tuesday into Wednesday. But the bigger headline will be the hot air mass pressing eastwards from the Midwest next week.
