Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0736 PM CDT Mon Jul 06 2020 Valid 070100Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHERN/CENTRAL PLAINS AND OVER THE MIDDLE ATLANTIC... ...SUMMARY... Scattered severe thunderstorms will continue across parts of the northern/central Plains tonight. Isolated severe will also continue this evening across the Middle Atlantic. ...Middle Atlantic... A large cluster of disorganized thunderstorms has evolved over the Middle Atlantic this evening. A significant cold pool has formed beneath this cluster of storms which has stabilized much of NJ/eastern PA and southern NY. Air mass remains fairly unstable along a corridor from south-central PA to southern MD and this should be the zone where the strongest convection persists for the next several hours. Isolated damaging winds remain the primary threat. ...Northern/Central Plains... Several long-lived supercells are tracking southeast across the northern High Plains this evening. Favorable east-southeasterly low-level inflow is noted ahead of this activity over southeast MT to the northern slopes of the Black Hills. Scattered severe should continue southeast this evening, aided in part by an increasing LLJ that should focus into south-central SD by 06z. CAMs suggest this convection may propagate toward southeast SD by sunrise. Otherwise, a small cluster of severe is spreading slowly south across northeast NE. 00z sounding from OAX was modestly unstable with relatively steep lapse rates. It's not entirely clear how far this activity will propagate, so severe probs will be adjusted to account for some uncertainty ahead of this convection. ..Darrow.. 07/07/2020Read more
