Area Forecast Discussion National Weather Service Blacksburg VA 251 PM EDT Thu Sep 16 2021
SYNOPSIS. Shower and storm chances remain through at least Friday, but not widespread as moisture lingers from a dying front and tropical low off the east coast.
NEAR TERM /THROUGH FRIDAY/. As of 221 PM EDT Thursday .
Shower chances linger into Friday but still scattered about .
Lingering frontal boundary in the VA/NC piedmont will be the focal point for showers/few storms through early evening, interacting with tropical moisture from a low off the NC coast. Further west, there is another area of troughiness associated with upper trough axis in the central Appalachians. Showers will be widely scattered through early evening. Expect clouds and patchy fog overnight.
Friday, the deeper moisture edges east but still enough upper support and weak low level northeast flow to allow for a few showers/isolated storms to occur mainly midday to afternoon.
Lows tonight will be more like late Aug with lower 60s west to upper 60s east.
Consensus of models showing more sunshine Friday afternoon, so temperature forecast may be warmer, though weak northeast flow may keep it tempered in the 70s west, with lower to mid 80s east.
Forecast confidence is average to above average on temps/sky cover and average on pops.
SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/. As of 210 PM EDT Thursday .
Our weather pattern will continue be influenced mainly by a deep low pressure system drifting northward off the lower Mid-Atlantic coast. This low will continue radiating waves of moisture westward across the Appalachian chain, supporting spotty, in-and-out shower activity into Friday night. Better chances for rainfall will be found along the crest of the Blue Ridge and other ridgelines as the generally northeasterly winds around this low push the moisture into the higher terrain. Weather forecast models are still hinting that a nearly north-to-south boundary will develop Friday night across the Piedmont to the Blue Ridge, providing focus for shower activity, but am still uncertain where exactly or to what degree this any rainfall will develop.
On Saturday, the low pressure system will begin to shift northeast away from our region. Regardless, enough moisture will remain to support renewed spotty shower activity as daytime heating commences.
Saturday night into early Sunday, we can expect a cold front to pass across the central Appalachians before eventually stalling across the Carolinas. High pressure behind the front will shift across New England and then quickly extend southward across the Mid-Atlantic to wedge against the eastern face of the Appalachians. Airflow around this high pressure will bring easterly winds that will carry Atlantic moisture across the mountains. This will keep showers in the forecast Sunday and Sunday night, with highest rain chances found across the Highlands of North Carolina.
LONG TERM /MONDAY THROUGH THURSDAY/. As of 230 PM EDT Thursday .
Looking to Monday, with high pressure centered across New England and low pressure developing across the Rockies, winds across the Tennessee Valley will come from the south, drawing the remnant deep moisture left over from Tropical Depression Nicholas northward. At this time, it appears that the brunt of this moisture, and therefore the potential for heaviest rainfall, will remain to our west. That stated: will have to keep an eye out that some of this moisture may work it's way into the Highlands of North Carolina and western Virginia, providing the focus for heavy rain and flooding.
The better chances for heavy rain appear to be during the middle of next week, when a cold front approaching from the west will push the axis of deepest moisture more across the Appalachian chain.
AVIATION /19Z THURSDAY THROUGH TUESDAY/. As of 101 PM EDT Thursday .
Mainly VFR conditions across the area this afternoon except for a few pockets of lingering MVFR cigs near the mountains. Meanwhile, showers near LYH and DAN from earlier in the day have dissipated and all sites are dry as of 17Z. Additional showers and isolated thunderstorms should develop across the eastern sites around 20Z or so and migrate westward through 22Z. Coverage will be less at the western-most sites with an overall decrease area-wide after 00Z with the loss of daytime heating and instability. Later tonight there is good potential for stratus as well as at least some fog development, especially where rain occurs later this afternoon.
Winds through the period will be light/easterly.
Extended Aviation Discussion .
Spotty sub-VFR conditions will continue into Friday as shower and storm chances remain with low pressure advancing northward off the Atlantic coast. Drier conditions are expected heading into the weekend and early next week as high pressure builds over the region.
