Area forecast discussion, Jul 12, 6:49 AM EDT, 6 hours 47 minutes before
Area Forecast Discussion National Weather Service Blacksburg VA 649 AM EDT Sun Jul 12 2026 .WHAT HAS CHANGED... Aviation updated. Made adjustments to Pops this morning to account for radar/high res model trends. Probability of precipitation higher today than Saturday. Potential for some slow moving/anchored showers/storms along the Blue Ridge late this afternoon/evening. && .KEY MESSAGES... Key Message 1: Slow moving cold front will be the focus for showers and storms into Monday with temperatures trending cooler each day. Key Message 2: Much of the area will be dry with warm/hot conditions for mid-week. && .DISCUSSION... Key Message 1: Slow moving cold front will be the focus for showers and storms into Monday with temperatures trending cooler each day. Forecast centers around where front lays up today, but model trends indicate more of a southward push leading to an easterly low level wind, with west winds aloft. This pattern with shortwave support tends to bring slow moving or anchored showers/storms to the area, but with more cloud cover today, not as concerned with severe weather, despite the marginal risk. The potential for localized flash flooding is increasing, especially along the Blue Ridge, mainly south of Roanoke to Boone. At this time convective allowing models still differ on where this potential band of heavier rains may set up, so leaving out any flood watches, as 3/hr FFG still running 2-3", and do not thing the flooding threat is widespread enough. Until the 5h positive tilt trough pushes east Monday, shower chances will remain higher. Still being on the north side of the front will keep us cooler, but muggy with dewpoints in the 60s to lower 70s. Humidity during the day could be 70 to 90 percent. Key Message 2: Much of the area will be dry with warm/hot conditions for mid-week. High pressure will keep much of the region dry during the middle part of the week. A stray shower or storm cannot be ruled out, especially across the southern and western portions of the area. These regions will be farthest away from the center of the high, and by Thursday the next approaching weather system will be over parts of the Ohio and Tennessee Valleys. Temperatures are expected to trend milder each day, so that by Thursday, values about five to ten degrees above normal will be common across the area. When considering humidity as well, and we will be looking at much of the Piedmont of Virginia and North Carolina experiencing late afternoon heat index values around or a little over 100 degrees. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... Expect mainly a variable VFR to IFR cigs/vsbys this morning east to west, with LWB in the LIFR range. Should have some MVFR/VFR conditions for late morning, before showers/few storms arrive and start to lower most areas to sub-VFR. Still periods of VFR possible where it doesn't rain. Tonight, showers may linger but cigs and some vsbys will likely drop to IFR or worse over most areas. Amendments as necessary based on radar trends. Thunder chances seem low as cloud cover limits instability. Winds overall look to remain light and variable at around 5 knots or less. EXTENDED AVIATION OUTLOOK... Expect showers across the region through at least Monday, tapering off Monday night along with areas sub-VFR conditions for both ceilings and visibility. VFR conditions are expected for most locations Tuesday through Thursday. Prevailing winds for most locations during this period will generally be less than 7 kts. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
