Good Wednesday to everyone across the Western North Carolina Foothills and Western Piedmont…
We are looking at some changes in the weather as we head toward the weekend but for today we continue to find ourselves in a hot and muggy regime. A cold front will pass through the Western Carolinas by this afternoon, ahead of the front we have a chance at a few showers and thunderstorms. The one limiting aspect to this frontal passage is that we don’t have a large influx of moisture on southerly winds. Infact there is more of a westerly downslope orientation to the winds at the surface. Temperatures this afternoon will top out in the upper 80’s to low 90’s.
As this front moves east of the area tonight some drier air will push into the region, especially for everyone in the northern tier of the coverage area. Thursday will feature partly cloudy skies and temperatures about 3-5 degrees cooler than Wednesday’s values. But more notable will be the lower dewpoints (Upper 50’s- Low 60’s) that will make for a more comfortable feel outdoors.
This nice weather will get even better come the weekend as a large high pressure will dominate from the northern tier of the country. Friday and Saturday’s high will be even cooler as a secondary push of cooler air comes in. Temperatures both days could run in the low to mid 80’s with morning temperatures in the mid 60’s.
By the time we get to Sunday, attention will begin focus somewhat to our south as a pair of tropical systems could begin to influence the weather across the Southeast US. The likely re-emergence of former Tropical Storm Harvey in the Western Gulf of Mexico could make landfall along the Texas Coast by Sunday morning possibly as strong as a hurricane. Harvey once it makes landfall will not be a fast mover so excessive rainfall looks like a big threat for that area. Meanwhile a disturbance across Florida and the Bahamas could organize into potential tropical low and it would begin its trek up the Southeast US Coastline.
The Southeast coastal low would only influence the surface wind pattern for our part of the world on Sunday and Monday as it would keep northeast surface winds in place. There may also be a slight increase of clouds as a result of the flow coming off the Atlantic. Then by Tuesday a developing trough in the middle part of the country may be just the kicker to send Harvey out from the Western Gulf Coast Region and send it east or northeast.
Needless to say the end of the 7-Day Forecast period has a lot of uncertainty right now here in the Western Carolinas. We will monitor that timeframe early next week and adjust the forecast with each package.
