Frontal Passage leads to Fall Like Weather

Good Morning Folks! We'll deal with a frontal passage today (Tuesday) and this will bring with it widespread showers and thunderstorms this afternoon, followed by lingering scattered showers Wednesday afternoon as a small piece of energy swings into the region. NW flow will ramp up tomorrow and continue into Thursday, setting the stage for fall like weather, with a noticeable drop in humidity levels and of course cooler temps. Humidity slowly returns as we head into the weekend, settling back into a summertime setup by Saturday and temps are likely to rise to above normal levels by early next week. Looking at the long range outlook, it seems the last week of August and first week of September will feature a drier pattern and one that should result in above normal temps.

Cloudy skies, high moisture levels and a frontal passage will make up the action today, with widespread showers developing by the early afternoon hours, winding down this evening. The front itself will be off to the east by the early morning hours on Wednesday, however NW flow will be strong enough to keep isolated showers possible throughout the night, especially along the TN line. Temps today only reach the upper 70's, perhaps 80°F if enough sunshine pokes through the thickening cloud cover. Most of SW NC will pick up a half inch of rain, but it wouldn't surprise us to see a few locations closer to the TN line pick up an inch or more, more so because heavy downpours are a possibility. In terms of rainfall distribution, the higher amounts will be found along the TN line and any ridgelines facing due west, but also the larger ridgelines such as the Cowee Mountains and Great Balsams. Temps tonight dip into the low 60's under cloudy skies with isolated showers for most of the region through sunrise on Wednesday.

Wednesday is more or less a transition day as the front will be off to the east by sunrise, but as we mentioned above, NW flow keeps shower chances alive throughout the day. A round of showers is possible later in the day as an upper level piece of energy swings through the NW flow, so keep this in mind for your commute home. Temps will rise to the upper 70's in the valleys but only make it to the low 60's along the ridgelines! Overnight lows will dip into the upper 40's across our highest peaks and settle into the mid 50's for the valleys and by the evening hours, much drier air will be in place, so it may be a perfect night to crack open the windows!

Thursday through Saturday features a dry pattern but as moisture returns to the region this weekend, isolated pop up showers are possible, however coverage will be so small that most of us won't experience showers. Temps Thursday push again into the upper 70's across the valleys, but rise to the mid 60's across the ridgelines. Overnight lows Thursday night will be the coldest of the week as they dip into the low - mid 50's under clear skies for most of us, while the highest peaks flirt with the upper 40's once again.

We'll circle back Thursday to discuss the pattern change for late this week, which will lead to a warming trend as we head into next week. ENJOY!
