Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Aug 08 2024 00:56:10 ACUS01 KWNS 080056 SWODY1 SPC AC 080054 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Wed Aug 07 2024 Valid 080100Z - 081200Z ....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PART OF THE CENTRAL HIGH PLAINS AND IN EASTERN NORTH CAROLINA... ....SUMMARY... Scattered strong to severe storms with severe wind gusts and isolated large hail will continue across parts of the central High Plains this evening. An isolated tornado threat will also continue along and near the Atlantic Coast in North Carolina. ....Coastal North Carolina/Far Eastern South Carolina... Tropical Storm Debby will continue move slowly northwestward, moving inland this evening into eastern South Carolina. Rainbands currently extend from near the center of Debby into eastern South Carolina and southern North Carolina. The WSR-88D VWP near Wilmington, North Carolina has 0-1 km storm-relative helicity near 200 ms2/s2 with gradually veering winds in the low to mid-levels. This, combined with surface dewpoints in the upper 70s F, will support a tornado threat this evening. Tornadoes will be possible mainly with cells that can become semi-discrete within the rainbands of Debby. The threat could continue into the late evening and early overnight as Debby moves across South Carolina. ....Central High Plains... The latest water vapor imagery shows evidence of a subtle shortwave trough over the central High Plains. Near this feature, scattered thunderstorms are ongoing from western Nebraska into eastern Colorado. The storms are located along the western edge of a pocket of moderate instability, where the RAP is analyzing MLCAPE in the 1500 to 2500 J/kg range. RAP forecast soundings near the instability axis early this evening have 0-6 km hear in the 30 to 40 knot range, with 700-500 mb lapse rates of 7 to 8 C/km. This will continue to support isolated large hail within rotating cells this evening. Severe wind gusts will also be possible near and just ahead of the more intense line segments. The potential for severe wind gusts should continue for much of the evening as the cluster of storms moves across southwest Nebraska and northwest Kansas. ...Broyles.. 08/08/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
