More than 100k in the dark in Ashe, Avery, Watauga, Burke, Caldwell, Cleveland, Catawba, Alexander, Lincoln Co.

Discussion:
Upper level low over the Ohio Valley will keep light showers in the forecast today. We’re starting the morning with patchy fog and muggy conditions with temps in the mid to upper 60s. Thankfully, rainfall totals will remain light this afternoon with most of the region staying dry. It will remain slightly muggy with isolated showers Tuesday as highs warm into the low 80s. A cold front will clear out this stagnant pattern Wednesday bringing drier to the region late week. By this weekend another cold front will push into the area bringing back some rain chances Friday into Saturday with much cooler temperatures as highs top out in mid 70s Sunday.
Tropics Update:
TS Issac and TD Joyce developed in the Atlantic late last week. They will both dissipate without any major impact to land.
TD 12 is located over the Eastern Atlantic. No immediate threat to land, but it is forecast to become a major hurricane over the Central Atlantic by late week. Next name up is Kirk.
Broad Area of Low Pressure over the western Caribbean (this is one to watch) – right now producing disorganized showers and storms. This is one to watch as it drifts in the Gulf it could become a tropical depression or tropical storm later this week. It could bring heavy rain and gusty wind to the Gulf coast later this week.
