Severe thunderstorms are not expected Monday. ...Discussion... A return to negligible severe potential across the CONUS will occur on Monday. In the West, a broad upper trough will progress with multiple embedded shortwave impulses. The primary impulse will move across parts of CA into the southern Great Basin, aiding in overall amplification of the trough by Monday night. A large plume of cool mid-level temperatures combined with modest

A few thunderstorms may occur over parts of southern Florida and the Keys on Monday. ...Synopsis... As upper short-wave troughing departs the Northeast Monday, briefly zonal/westerly flow aloft will prevail. Later in the period, however, gradual amplification of the flow field will begin over the West, as a short-wave trough digs southeastward out of the Pacific Northwest across the Great Basin toward the Four Corners region.

Locally strong wind gusts are possible Sunday morning, particularly across portions of the Southeast but possibly as far north as the Mid-Atlantic region. ...Synopsis... A vigorous/fast-moving short-wave trough -- embedded in broader cyclonic flow aloft -- will move quickly eastward across the eastern quarter of the U.S. Sunday. As this feature reaches the Atlantic

Severe weather is expected from East Texas into much of the Southeast and parts of the Mid-South on Saturday. Scattered to numerous damaging wind gusts and a few tornadoes are the primary threats.

Thunderstorms are not expected on Wednesday. ...Synopsis... A deep mid/upper-level trough will remain in place over most of the CONUS on Wednesday. Anomalously cold conditions are expected from the Great Plains to the Eastern Seaboard, in the wake of a strong cold front. Weak MUCAPE may persist across far south FL and the Keys very early in the forecast period, but deep convection appears unlikely due to warm temperatures

Thunderstorms are not forecast on Tuesday through Tuesday night. ...Synopsis... Thunder potential will be nil across much of the CONUS during the D2 period. Deep convection will be relegated to the Gulf, initially over the west-central portion before spreading towards the southeast part late. The slimmest of elevated buoyancy (MUCAPE below 100 J/kg) along the Upper TX to LA Gulf Coast may coincide with mixed-phase parcels, supporting weak convection

Thunderstorms are not forecast on Monday or Monday night. ...Synopsis... Thunderstorm potential is negligible across the CONUS on Monday through Monday night. One exception could be from the Middle TX to southwest LA Gulf Coast where weak elevated convection should develop early morning Tuesday. This will occur with strengthening warm-moist advection centered on 750-700 mb, downstream of a positive-tilt mid/upper-level longwave trough.

A tornado and isolated damaging winds will be possible across central Florida through Sunday afternoon. ...Central FL... Within a longwave upper trough over much of the CONUS, an intense mid-level jet streak will move across parts of the Southeast and off the Mid-Atlantic coast by 12Z Monday.

Isolated thunderstorms are possible across the Lower Mississippi and Tennessee Valleys, and central Gulf Coast region Friday night into early Saturday morning. ...Synopsis... A short-wave trough digging southeastward out of western Canada across the north-central U.S. will partially phase with a second trough moving out of the Desert Southwest across the southern Plains, resulting in evolution of large-scale troughing across the CONUS.
