Severe Storms

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 AM CDT Sat Mar 15 2025 Valid 161200Z - 171200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE ATLANTIC COASTAL STATES... ...SUMMARY... Isolated severe thunderstorms with a few tornadoes, scattered damaging winds, and marginally severe hail will be possible on Sunday across parts of the East. ...Atlantic Coastal States... At the start of the period, a mid-level trough will be located in the mid Mississippi Valley, with south-southwest flow in place across much of the eastern U.S. A 90 to 100 kt mid-level jet streak should be located over the southern Appalachians. At 12Z on Sunday, a broken line of strong storms is expected to be ongoing within relatively close proximity to this jet. The stronger cells within this broken line may be associated with an isolated severe threat, as it moves eastward across Virginia, the Carolinas, southeast Georgia and northern Florida. The severe threat is expected to ramp up during the mid to late morning as surface temperatures warm ahead of the line. Isolated severe gusts should occur with the more organized short multicell line segments. Cells that remain discrete could also have a threat for isolated large hail and tornadoes. The tornado threat is expected to remain isolated, with the greatest potential in the central Carolinas and south-central Virginia. The severe threat is expected to be maintained into the afternoon, as the storms move toward the Atlantic Coast. While the shear environment will be impressive, instability is forecast to remain weak with poor low-level lapse rates. This should keep any severe threat relatively isolated. ...Southern and Central Appalachians... A mid-level trough will move slowly through the mid Mississippi Valley on Sunday, as a jet streak translates northeastward into the central Appalachians. During the morning, convection that is located near a pre-frontal trough, will move eastward away from the higher terrain and into the lower elevations of the Atlantic Coastal Plains. Further west, a cold front is forecast to advance eastward to near the crest of the southern Appalachians by afternoon. Ahead of the front, surface heating will take place allowing for weak destabilization. In addition, the environment will consist of cold air aloft and strong large-scale ascent near the mid-level jet. This should support a marginal severe threat in the afternoon, with isolated severe gusts and hail possible. This severe threat could extend northeastward into parts of West Virginia and Pennsylvania, where weak instability is also forecast to remain weak. ..Broyles.. 03/15/2025 Read more

The tornado threat is expected to remain isolated, with the greatest potential in the central Carolinas and south-central Virginia. The severe threat is expected to be maintained into the afternoon, as the storms move toward the Atlantic Coast. While the shear environment will be impressive, instability is forecast to remain weak with poor low-level lapse rates. This should keep any severe threat relatively isolated. ...Southern and Central Appalachians... A mid-level trough will move slowly through the mid Mississippi Valley on Sunday, as a jet streak translates northeastward into the central Appalachians. During the morning, convection that is located near a pre-frontal trough, will move eastward away from the higher terrain and into the lower elevations of the Atlantic Coastal Plains. Further west, a cold front is forecast to advance eastward to near the crest of the southern Appalachians by afternoon. Ahead of the front, surface heating will take place allowing for weak destabilization. In addition, the environment will consist of cold air aloft and strong large-scale ascent near the mid-level jet. This should support a marginal severe threat in the afternoon, with isolated severe gusts and hail possible. This severe threat could extend northeastward into parts of West Virginia and Pennsylvania, where weak instability is also forecast to remain weak. ..Broyles.. 03/15/2025 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 AM CDT Sat Mar 15 2025 Valid 161200Z - 171200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE ATLANTIC COASTAL STATES... ...SUMMARY... Isolated severe thunderstorms with a few tornadoes, scattered damaging winds, and marginally severe hail will be possible on Sunday across parts of the East. ...Atlantic Coastal States... At the start of the period, a mid-level trough will be located in the mid Mississippi Valley, with south-southwest flow in place across much of the eastern U.S. A 90 to 100 kt mid-level jet streak should be located over the southern Appalachians. At 12Z on Sunday, a broken line of strong storms is expected to be ongoing within relatively close proximity to this jet. The stronger cells within this broken line may be associated with an isolated severe threat, as it moves eastward across Virginia, the Carolinas, southeast Georgia and northern Florida. The severe threat is expected to ramp up during the mid to late morning as surface temperatures warm ahead of the line. Isolated severe gusts should occur with the more organized short multicell line segments. Cells that remain discrete could also have a threat for isolated large hail and tornadoes.
