SPC Mar 2, 2022 2000 UTC Day 1 Convective Outlook

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0120 PM CST Wed Mar 02 2022 Valid 022000Z - 031200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... No thunderstorms are forecast across the United States today or tonight. ...Discussion... No changes are required to the ongoing outlook. ..Goss.. 03/02/2022 .PREV DISCUSSION... /ISSUED 1011 AM CST Wed Mar 02 2022/ ...Synopsis... Northwesterly flow aloft will continue across the eastern half of the CONUS today in the wake of a trough passage off the East Coast. A second low amplitude shortwave/upper-level jet over the Ohio Valley will reinforce dry offshore flow at the surface across the eastern half of the country. The limited surface moisture and lack of stronger forcing for ascent will keep thunderstorm chances very low. To the west, another low-amplitude shortwave trough moving onshore across the Pacific Northwest will support scattered showers and shallow convection through the day. However, warm temperatures aloft and the resulting poor thermodynamics will likely not support thunderstorms. Read more CHECK UPDATE ZOOM GRAPHIC
