SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0223 PM CDT Mon Sep 23 2024 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential is uncertain, but limited, on Wednesday. ...Synopsis... The upper-level trough across the Midwest into the Mid-South is expected to evolve into a strong trough in the lower Great Lakes/Northeast and a cut-off low in the Ozarks. A surface cold front is expected to be positioned from near the upper Ohio Valley southward into Mid-South and westward into the southern Plains. In the Gulf of Mexico, current NHC forecasts show a hurricane moving north-northeastward in parts of the eastern Gulf. ...Western/central New York... A narrow warm sector may exist ahead of the cold front. Subtle forcing from the trough to the north may promote storm development during the afternoon. Given the potential for cloud cover/precipitation early in the day, along with the strongest mid-level ascent arriving during the evening, uncertainty is too high for severe probabilities. ...Mid-South/Southeast... Strong mid-level flow around the eventual cut-off low could allow for some storm organization near the cold front. There is a fairly strong signal for precipitation to be ongoing during morning and into the afternoon. Surface-based destabilization is at best uncertain and perhaps not very likely. No severe probabilities will be added. ...Portions of the Florida Peninsula... Given the forecast track of the tropical cyclone by NHC and available model guidance, there is some potential for low-level wind fields to increase in parts of the southern/central Florida Peninsula towards Thursday morning. Given the trough to the north of the expected hurricane and the uncertainty of the exact position of the system and any related outer convective bands, will continue to withhold low tornado probabilities. ..Wendt.. 09/23/2024 Read more

MD 2097 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHERN KENTUCKY...MIDDLE/EASTERN TENNESSEE AND FAR WESTERN NORTH CAROLINA
Mesoscale Discussion 2097 NWS Storm Prediction Center Norman OK 0113 PM CDT Mon Sep 23 2024 Areas affected...Portions of southern Kentucky...middle/eastern Tennessee and far western North Carolina Concerning...Severe potential...Watch unlikely Valid 231813Z - 231945Z Probability of Watch Issuance...20 percent SUMMARY...Convection should gradually expand in coverage this afternoon with a few stronger multi-cell clusters possible. Isolated damaging winds are the most likely threat with the more persistent/stronger storms. Environmental conditions are not overly conducive for longevity or severity, a watch appears unlikely. DISCUSSION...As of 1810 UTC, afternoon visible and radar imagery showed scattered thunderstorms developing south of a stationary frontal zone over parts of the TN Valley and southern KY. Driven primarily by strong diurnal heating of a seasonably moist (upper 60s to low 70s F dewpoints) air mass, SPC mesoanalysis shows 1000-1500 J/kg of MLCAPE, despite poor mid-level lapse rates. In the absence of significant height falls aloft, convective coverage should gradually increase through the afternoon with continued heating. As storms deepen, flow aloft will also gradually increase from the west. While area VADs are not overly strong, especially with eastward extent, 25-30 kt of flow aloft will support some potential for organization into multi-cell clusters. Damaging winds associated with water-loaded downdrafts appear to be the most likely threat given poor low and mid-level lapse rates and limited storm organization. Hi-res model guidance and observational trends suggest storms will gradually move eastward into parts of eastern TN/southeast KY and the western Carolinas later this afternoon/evening. An isolated risk for damaging winds will accompany the stronger/more persistent clusters. However, the lack of more significant upper-level support, poor lapse rates and marginal deep-layer shear suggests the threat is unlikely to be widespread enough to warrant a WW. ..Lyons/Guyer.. 09/23/2024 ...Please see www.spc.noaa.gov for graphic product...

Apples were shriveling on the trees in a Fayette County orchard. A 17-acre wetland preserve has been dry for the past month. What would have been the deepest part of the wetland where the water was about five feet deep has cracks in the soil about six inches deep. Farmers’ Advance (Camden, Mich.), Sept 23, 2024
