Just a few showers over the Mountain Empire this morning, and not expecting any flooding from this. && .KEY MESSAGES... 1) Isolated shower and thunderstorm chances continue today, with increasing severe threat on Friday and Saturday. && .DISCUSSION... KEY MESSAGE 1: Isolated shower and thunderstorm chances continue today, with increasing severe threat on Friday and Saturday. The large scale pattern continues to remain largely unchanged from earlier in the week, with upper level ridging remaining quasi-stationary across the western Conus, and upper level troughing across the Northeast. At the surface, a stationary front will generally remain within the vicinity of the Virginia and North Carolina border through at least the weekend, which will allow for daily chances of showers and thunderstorms. With the upper level pattern mentioned above, there continues to be a marginal threat for Mesoscale convective systems to enter the area along this stationary front out of the Ohio valley through the weekend. There continues to be some uncertainty in the severity of these systems as they approach the area, as timing of them entering the area will determine how severe they will be. If these systems approach during the afternoon and evening hours, with a peak unstable environment over the region, then increased chances for severe winds will be possible; however, if these systems approach overnight or during the early morning hours, the chances for severe winds diminish significantly. By late Friday, the upper level ridge also starts to build over the central Gulf states, which will nudge the train tracks so to speak for these MCS further north and east of the region during the weekend. Overall, the chance for showers and thunderstorms looks to continue for the next several days, with today remaining limited in coverage for much of the region. Temperatures through the period will likely stay above normal except a brief drop to near normal this weekend. && .AVIATION /12Z THURSDAY THROUGH MONDAY/... VFR conditions are expected for a majority of the TAF period for all terminals. During the early morning hours, lowering CIGs and VSBYs due to river valley fog are impacting BCB and LWB. These IFR to LIFR restrictions look to lift to VFR levels shortly after sunrise. VFR conditions are expected at all terminals through the remainder of the TAF period, with only isolated shower and thunderstorm activity possible for today. Possible river valley fog and low CIGs look to impact BLF, BCB, and LWB again early Friday morning. Winds will generally remain light from the west/northwest at 10 knots or less. Winds look to go calm after 00 UTC Friday at all terminals. OUTLOOK... Pattern trend continues with daily chances for storms, though the best chance for organized storms is Friday and Saturday, otherwise more diurnal activity into the weekend. Mainly VFR outside of any storms and late night fog/stratus. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...EB/WP AVIATION...EB/WP
