Warm Sunday; Then Big Change

Today is the last Sunday of summer on the calendar and on the weather map. Warm high pressure holds for one more day. While isolated afternoon thundershowers are in play, coverage should be less than yesterday. Beginning Monday, a cool wedge digs into the Southern Appalachians. Expect thickening clouds Monday with fog and periods of light rain developing. Tuesday, we are socked in with clouds, fog, and rain. A front moves through Wednesday evening with rain and thundershowers. Periods of heavy rain are possible late Tuesday through Wednesday evening. Cooler air arrives Thursday.

Today is the last day of MerleFest.org in Wilkesboro, NC. Melissa Etheridge closes out this fabulous weekend at Sunday afternoon. RaysWeather.Com is the official forecast source for the festival. Our Hour-by-Hour Forecast is available.

Forecast Discussion

We remain in a humid airmass, but triggers for afternoon thundershowers are even less than the last few days. Sunday is seasonally warm with isolated afternoon showers and thundershowers.

High pressure centered to our northeast wedges down the east side of the Appalachians Monday and Tuesday. We have thickening clouds Monday with some fog and showers increasing in coverage in the afternoon and overnight. Tuesday is cloudy, wet, cool, and foggy. Periods of heavy rain are possible late Tuesday and Tuesday night.

A sharp front moves through from the northwest Wednesday evening. Wednesday is rainy with thundershowers possible. Periods of heavy rain are possible through evening.

Clouds decrease early Thursday and you will know you are in "new air"--drier and cooler. Canadian high pressure will move across the Appalachians late this week. Fall begins on the calendar Wednesday; Thursday and Friday will be appropriately cool. Saturday afternoon will be a couple degrees warmer.

Tropics... Tropical Storm Odette transitioned into just a low off the New England Coast. Tropical Storm Peter formed yesterday and could head toward Bermuda by the end of this week. A tropical depression farther east in the Atlantic may become Tropical Storm Rose. None of these will have any direct impact on our weather.
