SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1136 PM CST Tue Nov 17 2020 Valid 191200Z - 201200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The threat for thunderstorms should be negligible on Thursday. ...Synopsis... The large-scale flow regime will trend more zonal into Thursday as a series of midlevel shortwave troughs progress inland over the northern Rockies and northern Plains. Rising heights with time over the Pacific Northwest coast suggest that shallow convection is unlikely to produce much if any lightning. Some shallow, elevated convection will be possible during the day across the northern Plains where lingering steep lapse rates and moisture aloft could contribute to very marginal buoyancy rooted above the surface. However, the threat for thunderstorms should remain too low for an outlook area. Elsewhere, gradual moistening in easterly low-level flow could support a few convective showers across far south FL and the Keys, but pronounced midlevel convective inhibition will keep the convection too shallow/warm for charge separation. ..Thompson.. 11/18/2020
