Area Forecast Discussion National Weather Service Charleston WV 1012 PM EDT Mon Jun 11 2018 .SYNOPSIS... Unsettled conditions expected through mid week. Front late Wednesday may reduce rain chances for the end of the week. && .NEAR TERM /UNTIL 2 AM TUESDAY MORNING/... As of 1010 PM Monday... Will tweak the pops and sky cover a bit overnight to better represent current trends. As of 605 PM Monday... Will update pops to adjust for current radar and HRRR trends for late this afternoon and early this evening. As of 105 PM Monday... Latest surface map shows a stationary front was located across portions of southeast Ohio and the northern counties of West Virginia. This boundary and a mid-level disturbance was resulting in widespread showers across much of the region. Have not seen much in the way of thunderstorms. However, still can not rule one or two out until around sunset. Some areas across our northern counties have seen rainfall amounts around or in excess of an inch. The showers should be exiting the areas where the heavier rain fell and do not expect to see any water issues. Areas farther south could still see some heavier rain amounts this afternoon as PWAT values are still quite high. Will have to continue to watch rainfall amounts. However, do not expect any water issues at this time. The boundary is forecast to push south tonight with drier air filtering in from the northeast. Northern portions of the area should be dry with some showers possible across the south. The front will begin to return back north as a warm front on Tuesday with precipitation chances increasing from the southwest. Models suggest thunderstorms will be possible and have continued mention of storms in the forecast. Clouds and precipitation have acted to keep temperatures cooler than expected today. MAV guidance is warmer for highs on Tuesday than MET guidance. Believe there will be enough breaks in the clouds for temperature to warm to near MAV numbers. In addition, a blend of temperature guidance shows values close to the MAV and will generally be followed. Also used a blend of guidance for lows tonight. && .SHORT TERM /2 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... As of 345 PM Monday... Shower and thunderstorms chances remain high through Wednesday evening as a frontal boundary works slowly across the region. PWATS remain elevated so some localized flooding will be a possibility due to the repeating rounds of showers and storms that are expected. Temperatures are tricky due to cloud cover and rain potential so stuck with the blended model guidance which offers lows in the 60s and highs in the muggy 80s for most locations. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 345 PM Monday... Cold front sinks south of our region on Thursday...but just barely. Behind this front, models indicate that a drier airmass will advect into much of the area with dewpoints falling into the 50s and low 60s by late Thursday into Thursday night. This should quell our shower/storm chances for a time, but the airmass slowly modifies as we go into the weekend bringing a renewed threat for precip. The blended model guidance PoPs were fairly high considering the strength of the ridge building overhead and low initial dewpoints. So, pared PoPs back some and made them more diurnal in nature and focused on the higher terrain Friday and Saturday afternoon before smearing them out over the entire CWA Sunday into Monday. A complicating factor is MCS potential with the area remaining in northwest flow through the weekend and on Monday as the ridge builds in but predictability is too low to factor that in right now. There will be no big change in temps behind the front, except for lows Thursday night which should take advantage of the lower dewpoints to fall into the comfortable 50s to low 60s. The mercury will then inch upwards through Monday as the ridge builds in. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/... As of 605 PM Monday... A frontal boundary will linger across the area overnight, then push back northward on Tuesday. This will allow for some restrictions in showers and thunderstorms at times. Tonight is a tough forecast regarding fog. Some areas got an abundance of rain, but there will be some flow overnight. Confidence in whether fog will form or not is low. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z WEDNESDAY... FORECAST CONFIDENCE: Low. ALTERNATE SCENARIOS: Timing and restrictions in showers and thunderstorm could vary. Fog may or may not form overnight.
