Area Forecast Discussion National Weather Service Nashville TN 238 PM CDT Sun May 24 2020 .DISCUSSION... Broke out once again a late afternoon zone grouping to emphasize continued development of isolated to scattered showers and thunderstorms as remaining afternoon hours progress. Otherwise, a blended model consensus solution continues to be used through next Sunday. Models continue to be in general good agreement with big picture details, although in some instances quandaries concerning microscale details still persist. Expect this late afternoon diurnal driven convection to diminish as early evening hours tonight progress. Blended model consensus solution remains quite consistent since yesterday morning's model runs. Still looks like Memorial Day through at least end of work week a weather pattern will develop supporting at least mid afternoon to early evening shower and thunderstorm development each day. Aloft, this weather pattern consist of an upper level blocking ridge remaining quasi stationary and enhanced across locations approaching U.S. eastern seaboard while a cut off upper level low drops into southern plains and remains quasi stationary across this region through at least the Thursday afternoon hours. This weather pattern will support a more robust moisture advection fetch established from northern Gulf of Mexico Region into mid state region during this time. Just like yesterday at this time, multiple model sounding instability indicies support diurnal driven convective development, including high afternoon CAPE values. A shallow surface boundary may still try to push southward through mid state region as next Saturday progresses. This due to fairly strong surface/lower level atmospheric high pressure push into/across Ohio Valley Region, and eventually into mid state region. In upper levels though, upper level troughing may slightly deepen from northeast to southwest across mid state region as synoptic upper level trough becomes more enhanced across eastern Canada down through the Appalachians. It is expected that passing front will be rather shallow in nature as it pushes through mid state region. It still could potentially be until at least Monday for decent drying to occur across our area. Thus expect potential of isolated to scattered showers and thunderstorms to persist across mid state region through upcoming weekend also. As for temperatures, they will remain several degrees above seasonal normal values through first part of next weekend. Memorial Day will be warmest day of period, with highs mid to upper 80s, lower 80s higher elevations of Cumberland Plateau Region. So agree with morning discussion reasoning that heat and humidity will definitely be turned up for next several days across mid state region. && .AVIATION... 18Z TAF DISCUSSION. Short term models all have very isolated convective coverage this afternoon so went ahead and removed VCTS from all sites. One feature to watch will be a small mesolow noted on visible satellite lifting northeast out of West Tennessee. There's a small chance this will be able to trigger a couple showers and storms that potentially affect CKV, BNA, or MQY. Confidence in this idea is not high enough, however, to include. Some light fog at CSV near dawn is possible. Otherwise, tafs will be VFR. Winds will mainly be around 5 kts out of the south. && .PRELIMINARY POINT TEMPS/POPS...
