Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SABINE RIVER VALLEY INTO THE LOWER TO MID MISSISSIPPI VALLEY SUMMARY Thunderstorms with potential for isolated severe wind gusts and perhaps a brief tornado or two will be possible today from the Sabine and Lower Mississippi Valleys northward into the Mid Mississippi Valley. Sabine River Valley/Lower to Mid Mississippi Valley An upper-level trough will move across the Great Plains today, as cyclonic south-southwesterly flow precedes the system over the lower to mid Mississippi Valley. Ahead of the system, a north-to-south corridor of low-level moisture will be in place along and ahead of a pre-frontal trough. Near the moist axis, a long broken line of thunderstorms will be ongoing at the start of the period from western Missouri southward into western Arkansas and east Texas. This line will progress eastward into the lower to mid Mississippi Valley during the day. As it does so, surface temperatures will warm ahead of the line allowing for weak destabilization. Any potential for moderate instability will be minimized by abundant cloud cover. Over the top of this airmass, moderate to strong deep-layer shear will be present, which will support an isolated severe threat during the afternoon and evening. Line segments that can become semi-organized will have potential for isolated severe wind gusts. In addition, a marginal tornado threat will be possible with any QLCS structures. The severe threat will be minimized by poor lapse rates. The threat could persist into the late evening or even into the overnight period as the line moves eastward across the lower to mid Mississippi Valley, toward a strengthening low-level jet.
