Area forecast discussion, May 14, 12:40 PM EDT, 33 minutes before
Area Forecast Discussion National Weather Service Charleston WV 1240 PM EDT Mon May 14 2018 .SYNOPSIS... Unsettled pattern dominates the work week with thunderstorm chances and temperatures remaining above normal. && .NEAR TERM /THROUGH TONIGHT/... As of 1240 PM Monday... Updated product suite for inclusion of Severe Thunderstorm Watch 88 for a good chunk of our northern CWA. Again, the southern extent to the severe weather threat is uncertain but watch area highlights the counties under greatest threat and can be extended southward if need be. Otherwise, no major changes with forecast or severe weather expectations going forward. Did increase PoPs a bit up north now with thunderstorms forming and heading east-southeast. As of 1018 AM Monday... Latest update from SPC places our northern counties into an Enhanced Risk for severe weather, with primarily a damaging wind threat later today. Convection should erupt as outflow boundary from activity over northern Ohio, now progressing through central Ohio, enters our northwest counties around 16-18z. This should then form into a line which will progress quickly southeastward through the remainder of the afternoon. Most of the HiRes guidance shows this scenario, with some variability on how far south the convection makes it. The inherited forecast seems to have placement of PoPs and timing down well based on current expectations so will not make any changes right now. The HiRes guidance is very progressive, with overnight convection remaining well north, so hydro concerns seem to be taking a backseat to the damaging wind threat. Will focus messaging on the increased severe weather threat and timing. As of 255 AM Monday... No major changes to the synoptic pattern governing the weather in the near term. Upper level dome of high pressure remains over the southern Appalachians, leaving zonal 500mb gradient flow most active across the far northern tier of the CWA. Models are hinting at an MCS developing over the southwestern Great Lakes, and propagating around the upper ridge in the 500mb gradient and into the upper Ohio Valley. It is a little unclear at this point as to what the origin of our convection will be later today in this region, whether is the remnants of this feature, or residual waves aloft, but regardless, this will be a main driver in the convection as it moves into moderately unstable air. Slight risk from SPC resides here, but the southern portion of the CWA, if it receives convective activity at all, should be in less unstable air. Thunderstorm threat will extend into the overnight. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... As of 220 AM Monday... Repetitive pattern continues through mid week with surface boundary oscillating in the vicinity as several waves move through. Hard to get too much detail into POP forecast with uncertainty in timing of each of these. Continued idea of showers and storms possible throughout the period, generally with max POPs during peak instability in the late afternoon and evening. Stuck with a consensus blend for temperatures which keeps both highs and lows well above average. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 220 AM Monday... Unsettled pattern continues through the long term forecast with a surface boundary in the area providing showers and thunderstorms from time to time. Timing any individual wave remains uncertain. Above normal temperatures continue with very little variation from day to day. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... As of 820 AM Monday... The overall weather pattern will remain the same...in a convective environment that will be dependent on upper level waves traversing the area to help initiate thunderstorm activity, which will largely be a post 21Z time frame type issue. Have utilized the PROB30 groups for the northern terminals. Will have to evaluate the fog potential for Monday night after rain unfolds.
