616 FXUS61 KRNK 050005 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 805 PM EDT Fri Jul 4 2025 .SYNOPSIS... High pressure will keep the weather mostly and quiet through the holiday weekend. Chances for showers and thunderstorms return early next week. && .NEAR TERM /THROUGH SATURDAY/... As of 800 PM EDT Friday... Key Messages: 1. A mostly dry evening. Ideal for 4th July celebrations. 2. Near seasonal temperatures. Scattered showers/storms which developed along I-64 corridor have diminished. Covington and Lexington got some wetting, but most areas remained dry today. Goshen ended up the winner with respect to rainfall with radar estimating close to 2 inches falling near Lake Merriweather. A gage report from Rockbridge Baths measured 1.61, and about two tenths of an inch occurred in Lexington. For the remainder of the evening, expecting tranquil weather. Surface high pressure and subsidence should promote dry weather with mostly clear skies through the remainder of the holiday. Patchy fog is possible tomorrow morning, especially in the river valleys and around the Alleghany Highlands, as the atmosphere decouples and an inversion sets in. Fog should dissipate fairly quickly after sunrise tomorrow with daytime heating and mixing, most likely by 9am or so. Saturday looks to be another mainly dry day, as high pressure and a dry airmass remains overhead. Will likely see clouds develop by the afternoon again, and high temperatures similar to today. The National Hurricane Center has begun issuing advisories for Tropical Deppression Three in the Atlantic, which is expected to impact the Carolinas.

Key Message: 1) Tropical disturbance off the Georgia coast to potentially impact southeastern portion of the region. The main takeaway with this part of the forecast is the tropical disturbance off the eastern coast of Georgia is projected to go inland and travel northeast through the states of North Carolina and eastern Virginia. Hurricane Hunters are planning to investigate the storm system further which will assist in understanding its potential strength and movement. The NHC has a 70% chance of this system developing into a tropical storm within the next 2 days. Even if this system was to become a tropical storm, it would quickly lose strength once it hits the mainland. Current hurricane model guidance suggests the storm may be inland enough to affect areas east of the Blue Ridge, especially in the NC Piedmont and Southside VA. The overall impact of this system looks to be minimal as winds will become easterly and shift to northwesterly as the system passes with wind gusts only up to 15 mph. Precipitation accumulation looks to be up to 0.25" but confidence in this part of the forecast is currently weak given the uncertainty of the storm`s projected path. Otherwise, dew points will begin to rise into the 60s and 70s regionwide and high temperatures will be in the mid-70s to mid-80s as a frontal system approaches from the northwest. The heat index is expected to be below Heat Advisory criteria but will be close to 90 degrees for areas east of the Blue Ridge. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 130 PM EDT Friday... Key Message: 1) Multiple opportunities for showers and thunderstorms next week. An approaching frontal system will stall over the Mid-Atlantic mid- next week to provide a boundary for storm initiation. Meanwhile, two upper level ridges form over the southwestern CONUS and southern coastal CONUS. While the southwestern ridge will do more of the heavy lifting, these systems will bring relatively zonal winds to the area and direct shortwaves from the Great Plains and through the Mid-Atlantic. Several shortwaves are expected next week and with the boundary front, as well as moist and hot conditions, daily showers and thunderstorms are expected to make a return to the region. While diurnal heating will provide plenty of CAPE, Thursday afternoon looks to be the only day to have enough shear for severe storm potential. Machine Learning model guidance also suggests the highest likelihood for severe weather will be during the latter half of next week. PWATs are forecast to be between 1.25-1.75" which is a little higher than this time of year, so repeated showers also raise a concern for flooding. Confidence on flood and severe potential is currently low due how far out these events are. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... As of 800 PM EDT Friday... Overall, VFR conditions will prevail for all TAF sites through the current TAF period, ending at 00Z Sunday. Aside for some scattered high level clouds and afternoon cumulus, not much to speak of with respect to cloud cover. Winds through the period are expected to remain light, less than 10 kts. Any late night fog should be confined to the mountain valleys, potentially impacting KLWB, otherwise no vsby restriction anticipated. EXTENDED AVIATION OUTLOOK... VFR conditions are expected outside of morning valley fog through early next week. May see some isolated to scattered storms Sunday into Monday with chances increasing into the middle of next week. Moisture from TD Three is expected to remain south and east of the forecast area, but may tease KDAN late Sunday into Monday. Periods of heavy rain are expected along the coast, mainly east of I-95... see hurricanes.gov for details. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
