Thunderstorms are not forecast across the continental U.S. through the remainder of today or into tonight. ...20z Update... No changes were made to the prior outlook. Broad high pressure over the central US will continue to favor cool, dry and stable conditions behind a cold front. This will negate thunderstorm potential. See the prior outlook for more info. ..Lyons.. 01/23/2025 .PREV DISCUSSION... /ISSUED 1013 AM CST Thu Jan 23 2025/ ...Synopsis... A shortwave trough currently moving through NM is forecast to continue east-southeastward across the southern Plains today, helping to induce an eastward shift in the mean upper troughing across the central and eastern CONUS. As it does, another surge of cold and dry continental air is anticipated across the Plains and MS Valley, with associated high surface pressure contributing to continued offshore flow. High surface pressure will remain over the western CONUS as well. Resulting dearth of low-level moisture will preclude thunderstorm development.
