SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1109 AM CDT Sun Jul 06 2025 Valid 061630Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING OVER PORTIONS OF THE CENTRAL PLAINS... ...SUMMARY... Scattered storms capable of producing severe wind gusts and large hail are expected along the central High Plains. Large hail and significant severe gusts are possible. ...Eastern WY/CO and western NE/KS... Subtle mid-level forcing will overspread eastern WY/CO this afternoon as a weak shortwave trough and associated mid-level speed max approach. Surface dewpoints are a little higher than yesterday, with greater CAPE aiding in the development of scattered afternoon storms over the foothills and along the DCVZ. Very steep mid-level lapse rates and 30kt+ of deep layer shear will promote a few supercell structures capable of large hail. As the storms build eastward, congealing updrafts will likely result in a greater risk of damaging winds through the evening over northeast CO and western NE/KS. ...Central Plains to IN/MI... A weak surface boundary extends from south-central KS across MO/IL into parts of IN/Lower MI. Morning visible imagery shows pockets of strong heating to the south of the boundary, where steep low-level lapse rates and ample CAPE will be present. Scattered thunderstorms are expected to develop along the entire length of the boundary later today. Winds aloft are sufficiently strong over MI/IN for some convective organization, with occasional bowing structures capable of damaging wind gusts. From IN southwestward, weak steering flow will result in slow-moving multicell storms with occasional intense downdrafts. ...NC... TD Chantal is moving slowly northward into central NC. A large shield of cloud cover surrounding the center is limiting heating, and low-level shear profiles have not been particularly strong. Nevertheless, 12z CAM solutions generally agree that the strongest updrafts today will be near and just northeast of the circulation center. A tornado or two is possible this these storms, and in any more isolated convection that might form in the outer bands over eastern NC. ..Hart/Moore.. 07/06/2025 Read more
