SPC Feb 27, 2022 1630 UTC Day 1 Convective Outlook

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1014 AM CST Sun Feb 27 2022 Valid 271630Z - 281200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms is negligible across the U.S. today and tonight. ...Synopsis... An expansive surface high will remain entrenched across the central CONUS today, limiting the potential for deep convection for most of the country. A weak cold front continues to push east/southeastward across the southeastern U.S., and will eventually move offshore later today. This may support a few offshore thunderstorms late this evening off the FL/GA/SC coast. Across the Pacific Northwest, onshore flow will continue to bring scattered precipitation to western OR/WA, but both observed and forecast thermodynamic profiles appear too marginal to support much lightning potential. ..Thompson/Moore.. 02/27/2022 Read more CHECK UPDATE ZOOM GRAPHIC
