Area Forecast Discussion National Weather Service Blacksburg VA 954 PM EDT Mon Jun 24 2024

High pressure and a less humid air mass over the Ohio Valley will be centered over the central Appalachians by Tuesday morning. A cold front crossing the region on Wednesday will bring a return of showers and thunderstorms, especially in the afternoon and evening.
Thursday and Friday are expected to be warmer and more humid with a low probability of any precipitation.

As of 945 PM EDT Monday...

Again, no major changes are planned for the overnight forecast.
Other than the far southeast portion of the region, skies have cleared. The southeast is expected to follow suit. Have made only minor adjustments to hourly conditions through the early morning hours of Tuesday.

As of 655 PM EDT Monday...

No major changes are expected to the ongoing forecast.
Currently, winds are still around 10 to 15 mph for much of the region along with some gusts near 15 to 20 mph. Around and just after sunset, these winds will trend to values around 5 to 8 mph and weaker. The cumulus clouds will also dissipate leaving a mostly clear to clear night across the region. Have tweaked hourly temperatures, dew points, wind speed/gusts, and sky cover to better reflect the latest conditions and expected trends through the late evening.

As of 215 PM EDT Monday...

Key messages:

- Dry and less humid

Surface dew points were already dropping behind the cold front that was pushing through southeast Virginia and eastern North Carolina. Cloud cover will erode after sunset and wind speeds will also diminish. Despite the drier air, the cooler temperatures over the warmer water of area rivers and lakes will result in shallow fog Tuesday morning. Little cloud cover is expected Tuesday and a large rise in temperatures will bring highs into the lower 80s to lower 90s.

As of 130 PM EDT Monday...

Key Messages:

1. Hot and more humid by Wednesday.
2. Showers and thunderstorms Wednesday into Thursday.

Nearly zonal flow aloft Tuesday night turns more southwesterly, as another trough digs into the Tennessee and Ohio Valleys, while a cold front approaches the central Appalachians from the west. Though surface high pressure will keep the weather quiet through the beginning of Wednesday, southwesterly flow ahead of the cold front brings in additional moisture and warmer temperatures, so a return to hot and more humid conditions Wednesday. Instability will increase over the area with diurnal heating, increasing potential for showers and thunderstorms as the front nears the area. Though timing details are still uncertain at this time, some guidance is suggesting prefrontal storms to develop over the Piedmont by early to mid afternoon, and then another round of storms attendant to the frontal passage in the west by the evening, as said in the forecast discussion from the previous shift. There is a marginal risk for severe thunderstorms, damaging winds being the greatest threat, and possibly heavy rain, given precipitable water values near the 90th percentile relative to climatology. However, the better upper dynamics look to stay farther north, closer to the upper trough.
Similar to the frontal passage this past weekend, the showers and storms with the front may not make it over the Blue Ridge Wednesday night, also noted in the previous forecast discussion, as instability decreases through the night.

High pressure builds back in over the region behind the front by Thursday, sliding across the northeastern US, which will keep the weather quiet for most into the end of the week. However, east to northeasterly flow around the high could bring some moisture into the area from the Atlantic, and the front lingers across the Carolina coast, so may see some showers and storms develop over that area Thursday afternoon.

Temperatures Wednesday will be the hottest of the forecast period, in the mid to upper 80s in the west, and mid to upper 90s in the east. The increased humidity will bump heat indices back into the upper 90s to near 100 in the Piedmont, though cloud cover and rain could impact high temperatures. Thursday will be several degrees cooler than Wednesday, closer to seasonal normals, behind the front.

As of 130 PM EDT Monday...

Key Messages:

1. Hot temperatures Friday and into the weekend.
2. Increasing probability for showers and storms Sunday.

High pressure will trek across the northeastern US Friday and into the weekend, and ridging at 500mb builds over the southeast states.
With heights increasing over the Mid Atlantic once again, temperatures will climb back to the mid to upper 90s in the east, and mid 80s in the west, though the higher elevations will remain a few degrees cooler. As the high continues to shift further east, return flow from the Atlantic will advect moisture into the area, and increasing surface based instability from diurnal heating will increase chances for afternoon showers and thunderstorms developing across the mountains Friday and Saturday. The next cold front approaches from the west by the weekend, and looks to cross the area Sunday. With better forcing via the front, and upper level support as mid level trough crosses the Great Lakes into the Northeast, there is higher probability for more greater coverage of showers and storms Sunday afternoon into the evening. Moderate to heavy rain looks possible with these storms, as forecast precipitable water values near the 99th percentile relative to climatology. High pressure builds back in over the region for Monday behind the front, bringing a return to mostly dry weather.

As of 725 PM EDT Monday...

VFR conditions are expected through the vast majority of the valid TAF period concluding at 00Z Wed/8pm EDT Tuesday. The exception will be some late night/early morning fog within mainly the mountains river valleys. Northwest to north winds around 10kts with gusts 15 to 20 kts will weaken fairly rapidly after sunset and either be sustained around 5 to 7kts or become light and variable through the night and into Tuesday.

Confidence in the above aviation forecast scenario is high.


VFR conditions expected through much of the week, with the only exception being areas of valley fog in the early morning hours, and with any storms Wed.

The chance of showers and thunderstorms will be confined to the southern Blue Ridge and foothills on Thursday and Friday.

Isolated afternoon and evening thunderstorms.are possible anywhere across the region on Saturday due to a hot and unstable airmass.
