SPC Oct 6, 2021 1730 UTC Day 2 Convective Outlook

SPC 1730Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1213 PM CDT Wed Oct 06 2021 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms will be likely on Thursday from parts of the Southeast northward into the southern Great Lakes. Additional thunderstorms will be possible from parts of the Intermountain West to the northern Plains. Severe potential is expected to be low with this activity on Thursday. ...Synopsis... An upper low over the mid-MS Valley will shift east/northeast toward southern Lake Michigan by Friday morning, with an attendant trough extending southward to the northern Gulf coast. A moist airmass will reside across much of the Southeast into the Ohio Valley. Areas of showers and thunderstorms are likely to be ongoing Thursday morning, along with widespread cloudiness. This will serve to limit heating and destabilization, despite a moist airmass. As such, instability will remain weak. While a couple of strong storms could develop across northern GA/SC, overall severe potential appears too limited to include probabilities at this time. Southwesterly deep-layer flow will persist across the western states as a series of weak shortwave impulses migrate across the Great Basin. Isolated thunderstorms are possible from northeast NV into northern UT/southeast ID during the late afternoon/evening. Instability will remain weak and vertical shear modest. However, steep midlevel lapse rates will overspread the region. While overall severe potential will remain low, a couple of storms could produce small hail, mainly across northern UT. ..Leitman.. 10/06/2021 Read more LIVE: spc.noaa.gov
