Backdoor Front to Provide a Refreshing Break from Late Summer Heat

Good Tuesday afternoon to everyone, plenty of things going on in the weather world...


Hurricane Humberto is on the move toward the east a few hundred miles off the Southeast US coastline. The storm will be no threat to the mainland US but could make a fairly close approach to Bermuda in the next few days.


A backdoor cold front is located across the Mid-Atlantic Region and back into the Midwest. That front will drop southward over the next 24 hours and will usher in some big changes to the weather here locally...





A look at the FutureCast is showing the evolution of things for the next 24 hours...a few showers are possible late today across the region as this front gets closer. By tonight, the backdoor front will be entering our northern tier of counties (Alexander and Catawba)







Shower chances may increase overnight as the front works west through the Foothills. Northeast winds will rush in overnight helping provide some upslope component to the low level flow. That and the convergence with the front could yield some wet weather overnight...







Shower chances will persist past daybreak and could provide a wet commute to school or work in the morning. Best chances of showers and/or drizzle will be along the Blue Ridge with drier conditions expected in the Southeast portions of the coverage area...









Northeast winds in a damming configuration will result in much cooler conditions for Wednesday and the rest of the work week. Tomorrow's high's will struggle to reach the 70's under mostly cloudy skies.


By Thursday, those same northeast winds along with the flow on the backside of Humberto should push much drier air in from the Mid-Atlantic and is going to provide the region with a fall preview of sorts, especially in regards to night time lows.


As you can see on the image below, water moisture content by Thursday has been greatly reduced to almost nothing from the Mid-Atlantic down through the Carolinas. And by Friday the dry and pleasant air will encompass all of the Southeast US...




Daytime highs Thursday and Friday will be in the 70's with refreshing morning lows in the lower to mid 50's. For our friends in the mountains, 40's are likely especially on Friday morning.


Unfortunately all good things must come to an end...by the weekend, surface wind flow will begin to take on a southeast orientation and that will gradually warm things back up.
