Moisture from what's left of Irma will keep our skies cloudy through the end of the work week. Temperatures will gradually cool from the mid-70s at kickoff to the low 70s by 4th quarter; overnight lows will drop into the mid-60s. It will not be widespread but just expect scattered, off and on showers through the morning. Scattered showers will be present throughout the day with highs in the upper 70s.
High pressure will slowly exit the region today and a limited amount of moisture from the remnants of Irma will move northward into the Northeast and CNY today and tomorrow. As we head into this evening, clouds will build in from the southwest as the leading edge of cloud cover and showers associated with once Hurricane Irma, slide in late tonight.
Temperatures could reach the low or mid-80s starting Wednesday.
- Weekend looks pretty good and summery for the last official weekend of summer.
It will become a bit muggier with more clouds building in today. Highs will be in the lower 70s with increasing humidity.
National Weather Service meteorologist Rodney Hinson said a warm front is expected to move from south to north across the Rock Hill area Tuesday, changing the wind directions from east to south or southwest. Temperatures should rise close to 80 degrees under a partly to mostly sunny sky.
Meteorologists also say Hurricane Jose, now north of the Bahamas, does not pose an immediate threat to the Carolinas. High pressure induces sinking motion in the atmosphere, which dries the air making it also very stable - the opposite of what showers need to form. Farther down the road, Jose should return on a northwestern path toward the East Coast of the USA, but extended models turn it toward the northeast and back out to the Atlantic in about a week.
