SPC May 28, 2021 0600 UTC Day 2 Convective Outlook

SPC 0600Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1223 AM CDT Fri May 28 2021 Valid 291200Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SOUTHEAST COLORADO AND NORTHEAST NEW MEXICO... ...SUMMARY... Widely scattered severe thunderstorms capable of large hail and severe gusts are possible Saturday for parts of southeastern Colorado and northeastern New Mexico. ...Central and southern High Plains... A weak mid-level disturbance is forecast to crest a flattened mid-level ridge over the southern High Plains on Saturday. Moist east-southeasterly upslope flow will maintain a fetch of appreciable moisture into southwest TX and southeast NM, with the northern periphery of the ribbon of moisture extending into eastern CO. A plume of steep mid-level lapse rates coupled with strong heating near the higher terrain, will favor diurnal storm development with storm coverage highest over southern CO and northeast NM. Strong to severe multicells and perhaps a supercell or two, will lend a risk for large hail and severe gusts. This activity will likely form near the terrain-preferred areas and move east-southeast into the High Plains during the late afternoon/evening. ...Northeast NC... A mid-level trough over the OH Valley will slowly move eastward during the period. A surface low will weaken during the day as it moves southeast from the VA/NC border to east of the Carolinas as a cold front pushes southeast. Forecast soundings show moderate destabilization over the coastal plain with upper 60s F dewpoints and 1000-2000 J/kg MLCAPE. A few strong to severe storms may be capable of an isolated wind damage threat. ..Smith.. 05/28/2021 Read more LIVE:
