Severe thunderstorms are not forecast through tonight across the contiguous United States. ...Synopsis... A mid-level low, initially over Baja California, will weaken as it evolves into an open trough, before reaching far west TX and Chihuahua, Mexico. Meanwhile farther north, a broad belt of strong cyclonic mid-level flow will encompass much of the northern tier of states east of the Rockies. The split-flow upper-air regime will be hostile to appreciable airmass modification over the Gulf Coast. A few weak thunderstorms are possible as pockets of elevated instability develop over TX and the Arklatex. Elsewhere, convective activity will be suppressed. ..Smith/Lyons.. 02/01/2023 Read more CHECK UPDATE ZOOM GRAPHIC
