SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0746 PM CDT Fri Jun 13 2025 Valid 140100Z - 141200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF THE HIGH PLAINS FROM SOUTHEAST MONTANA TO NORTHWEST TEXAS... ...SUMMARY... Scattered severe thunderstorms are expected this evening across much of the High Plains from southeast Montana into northwest Texas. Hail and wind remain the primary concern. ...01z Update... Mid-level speed max is currently translating across the northern Rockies and this feature should suppress the height field across western/northern MT as the evening progresses. Scattered strong-severe thunderstorms have developed ahead of the short wave and this activity will propagate across southeastern MT over the next several hours. Farther south across eastern WY/CO, high-level diffluent flow is contributing to scattered robust convection where moist southeasterly low-level flow has persisted, and is currently contributing to a corridor of moderate-strong instability. Some increase in the LLJ across the central High Plains may enhance the longevity of this convection, though deep-layer flow is somewhat lacking. More isolated strong/severe convection is also noted along the NM/TX border. These storms will propagate southeast with an attendant risk for some hail/wind. ..Darrow.. 06/14/2025
