Good Tuesday I'm Chief Meteorologist Christopher White. Our western counties are wet this morning as light Easterly flow banks moisture up against the Blue Ridge. Potential Tropical Cyclone 10 is inland over Charleston this morning and will track NNE along the Carolina Coast. Low pressure to the Northwest of the Carolinas starts to move into the region this afternoon bringing shower chances back later today. A cold front will cross the region and stall Wednesday along I-85. Tropical Storm Harvey continues to funnel torrential rainfall back into Houston. Harvey will finally begin to lift NE late today and tomorrow.
PTC10 along with a high pressure ridge to the east of Florida have created Easterly flow across the Carolinas. As the sun rises this morning we expect these showers to start to taper off. This afternoon there should be some breaks of sunshine. With the approach of that upper low from the NW and the attendant cold front apparoaching the mountains a few showers or storms will likely develop this afternoon. The best chance will be from Asheville, West. Those could move out into the foothills by late afternoon into the evening. As sunset occurs tonight these showers and storms should dicipate. Highs continue to be about 5 degrees below normal today, topping out in the mid to upper 70's.
Wednesday will feature a day where we are kind of in between systems. The cold front should be draped from West to East near the I-85 corridor. Harvey will once again be on land and begin his trek NE. PTC#10 should be a deepening fish storm, moving off the Carolina Coast. Expect mostly cloudy skies locally. Harvey's remnants look like they will begin to interact with the stalled cold front by late day Wesnesday. This likely will push the front back North as a warm front. Rainfall could be heavy at times going into Wednesday Night but we don't expect any flooding issues locally Wednesday Night. The heaviest rain will be across the SW mountains and the western slopes of the Blue Ridge Wednesday night and Thursday. Temps will continue to remain below normal, in the mid and upper 70's.
Thursday looks like a wet day. The old frontal boundary will stall again and Harvey will be lifting NE through the Mid Mississippi River Valley. Harvey will spread rich tropical moisture North but most of that for Thursday looks to remain over SC. Light and moderate rainfall is likely off and on Thursday across our viewing area. Temps remain below normal.
Friday continues to be unsettled and wet. With the front draped across the area and pieces of energy from Harvey rotating up into it, rain should continue off and on. High pressure will ridge South from the Great Lakes creating a wedge scenario. Going into Saturday. In fact high temps Saturday could remain in the 60's with periods of heavy rainfall. If there are any flooding issues it would be localized and quick to pass we believe at this time. We will continue to keep you updated on this evolving weather pattern.
