Becoming Cloudy; Yuck Monday

Sunday is pleasant but cooler than seasonal averages. A slow low moves across the Southeast early this week. Skies become cloudy and rain arrives by late tonight. Monday is a raw, chilly, gray, wet day. Tuesday is only slightly better. Showers linger into a warmer Wednesday. Expect 1"-2" of rain through the 3-day period with isolated higher amounts near the Blue Ridge. Merlefest is on our minds and in our schedules Thursday through Sunday. Weather for the festival looks very good overall--cooler than average and we cannot rule out a stray, light shower Thursday and Friday.

Voting is underway in the 2019 Blue Ridge Parkway Calendar Photo Contest. We received over 700 entries in the contest (the most ever). Many thanks to all the photographers for the great response. Voting will continue until May 1, 2018.

Forecast Discussion

This week's weather is dominated by a trough in the Eastern U. S. A couple of surface low will round the southern periphery keeping our weather cool overall, very wet early, and maintaining the threat of a stray shower until next weekend.

The first surface low reaches Mississippi today and South Carolina Tuesday. From there it heads slowly up the East Coast. Skies become cloudy today and rain arrives by late tonight. Monday is not a day for outdoor activities--cloudy, foggy, chilly, rainy. Tuesday is only marginally less raw. Showers linger into Wednesday with slightly warmer temperatures. Expect 1"-2" of rain through the 3-day period with isolated higher amounts near the Blue Ridge.

Computer guidance today keeps the next low suppressed in the Gulf with a weak front arriving from the northwest late Friday. I'm wary of being overly optimistic but will go with the drier forecast trend... a stray shower possible Thursday afternoon and in the PM hours Friday, then a dry Saturday. Expect temperatures to remain slightly cooler than seasonal averages. Merlefest clothing selection should account for pleasant days, cool nights, and the potential for a stray, light showers Thursday and Friday.
