Area forecast discussion, May 6, 3:11 PM EDT, 2 hours 16 minutes before
AREA FORECAST DISCUSSION National Weather Service Morristown TN 311 PM EDT Fri May 6 2022 .SHORT TERM (Tonight and Saturday)... Key Messages: 1. The severe thunderstorm threat will continue through the remainder of the afternoon, diminishing this evening. 2. Lingering showers under an upper low on Saturday, with cooler temperatures. Discussion: The threat of severe thunderstorms continues for the entire area, with the threat shifting to the northeastern portions over the next few hours. Radar signatures in last hour have shown less rotation, so the tornado threat may be diminishing, although it cannot be ruled out entirely yet in southern sections. The primary threats through the evening will be large hail and damaging winds. The large hail threat will be rising in the next hour or two as WBZ heights drop with the passage of the mid/upper trough axis. The severe threat will end once the trough moves east, which is expected to occur around 00-02Z. A slow-moving closed mid/upper low will track across the central Appalachians tonight, and be located near the Chesapeake Bay area tomorrow. Cold temps aloft and overcast cloud cover will keep temperatures well below normal through Saturday. Light showers under the low will be scattered to numerous through the day, with greater coverage in northern sections. DGS .LONG TERM (Saturday Night through Friday)... Key Messages: 1. Some lingering showers possible Saturday night, mainly across far NE TN and SW VA. 2. Warming temperatures and dry conditions into the new work week. Discussion: On Saturday night, an upper level low ENE of the CWA will continue to shift eastward through the weekend, all while a deepening trough over the western CONUS begins to amplify ridging over the midwest. Some lingering activity will be possible Saturday night as the upper level low still meanders eastward, however, just expect light rain showers generally in far northeast TN and southwest VA. Heading into the work week, the synoptic pattern will continue to amplify. This will result in upper level ridging and surface high pressure influencing the weather across the south and central Appalachian region. Warming temperatures can be expected into the midweek with temperatures above normal by Tuesday through Thursday. By the end of the week, guidance suggest the upper level low shifting ENE at the start of the period will sink back southward. There still remains some discrepancies among long term guidance, nonetheless, NBM has populated with a return of some slight chance to chance PoPs Thursday and Friday afternoon. Currently nothing stands out enough to go against it this far out. Temperatures should remain above normal Friday as well. KS && .AVIATION... 18Z TAF DISCUSSION. Thunderstorms will be affecting the area through the rest of the afternoon, tracking from SW to NE. Gusty winds are expected at the TAF sites with the storms, along with IFR vis in heavy rainfall. Most of this activity should exit the area by 00Z. Tonight, an upper low pressure system will track overhead, which will lead to low clouds developing at all sites. MVFR cigs are expected to prevail, although IFR may be possible at TYS and moreso at TRI. A few scattered showers will also linger into tomorrow morning at TRI.
