SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1218 AM CST Sat Mar 09 2024 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected on Sunday. ...Discussion... A moderately amplified and progressive large-scale pattern will exist over the CONUS on Sunday, with mid/upper-level troughs moving generally eastward over the Northeast States and Pacific Northwest/Great Basin, while a slower-moving southern-stream cutoff low moves across the southern High Plains. A cold front will continue to progress southeastward across central/southern Florida, in addition to clearing coastal southern New England early in the day. A marginal thermodynamic environment will support a low potential for thunderstorms (near 10 percent) in both of these regions near the front. Thunderstorms will also be possible across parts of the coastal Pacific Northwest, where steepening lapse rates associated with an inland-advancing upper trough will support isolated low-topped thunderstorms. ..Guyer.. 03/09/2024 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1150 PM CST Fri Mar 08 2024 Valid 091200Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN PARTS OF THE SOUTHEAST... ...SUMMARY... A few tornadoes and scattered damaging winds are possible through early evening across parts of the Southeast States. ...Southeast... An extensive swath of stratiform rain is ongoing across parts of GA/SC to the northeast of deeper convection that extends towards the central Gulf Coast. This ongoing activity will play a pivotal role in the overall severe threat in terms of both magnitude and timing. Latest guidance has generally trended towards more probable deep convection evolving east from the central Gulf Coast vicinity across parts of north FL and south GA during the morning to afternoon. This should occur as greater diurnal surface heating ensues ahead of it over the FL Peninsula. Low-level hodographs will be enlarged early with a gradual weakening trend into the afternoon as flow becomes veered and wanes. As such, a relative peak in the tornado/wind threat may occur during the late morning to early afternoon. Farther north into the Carolinas, the severe threat appears conditional on sufficient destabilization in the wake of the extensive rain swath shifting east-northeast through this morning. Guidance is insistent that at least weak surface-based instability should develop by afternoon. But with the likelihood of deep convection persisting in south GA/north FL, and recent observational trends, MLCAPE should tend to be rather limited. Still, with appreciable mid-level height falls and strong low to deep-layer shear, the conditional setup could favor a few low-topped supercells in the afternoon with a tornado/localized wind threat. ..Grams/Thornton.. 03/09/2024 Read more
