ACUS02 KWNS 140556 SWODY2 SPC AC 140555 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1255 AM CDT Sat Jun 14 2025 Valid 151200Z - 161200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN AND CENTRAL HIGH PLAINS... ...SUMMARY... Scattered severe storms, capable of large hail and severe wind gusts, are expected on Sunday in parts of the northern and central High Plains. Additional strong to severe storms are possible in parts of North Carolina and Virginia. ...Central and Northern Plains... A mid-level ridge will remain in place across the High Plains on Sunday, as a subtle shortwave trough moves into the central and northern Rockies. At the surface, a low is forecast to deepen over Wyoming as upslope easterly flow remains in place across much of the central and northern Plains. Across the moist airmass, surface dewpoints will be mostly in the 60s F, which will contribute to the development of moderate to strong instability by afternoon. Convection is expected to initiate in the higher terrain of the northern High Plains, with storms moving eastward into the lower elevations during the mid to late afternoon. Large-scale ascent should remain relatively weak, favoring discrete modes. Forecast soundings near the instability axis at 21z have 0-6 km shear around 40 knots which will support supercell development. In addition to the shear, 700-500 mb lapse rates are forecast to be very steep in the 8 to 9 C/km range. This will be favorable for large hail with supercells. Hailstones greater than 2 inches in diameter will be possible within the more intense cores. A wind-damage threat is also expected to develop. Low-level flow will increase during the early evening, which will help maintain a severe threat. Further to the east into parts of the mid Missouri Valley, and southward into the southern Plains, convective coverage is expected to remain very isolated due to warm air aloft and the presence of the mid-level ridge. In spite of this, some convection will be possible as low-level convergence increases during the day along pre-existing outflow boundaries. Mid-level directional shear is evident on forecast soundings. This could be sufficient for some cell organization and a severe threat. Hail and strong wind gusts would be possible. ...Northern North Carolina/Southern Virginia... A subtle mid-level shortwave trough is forecast to move into the southern and central Appalachians on Sunday. At the surface, a lee low is forecast to develop over central North Carolina. Surface dewpoints will be in the upper 60 to mid 70s F from the Appalachian foothills to the North Carolina and Virginia coasts. Topographic forcing in the Appalachians and large-scale ascent ahead of the approaching trough will support scattered convective initiation around midday. These storms will move eastward into the lower elevations during the afternoon. As low-level lapse rates become steep in the mid to late afternoon, a few marginally severe wind gusts will be possible with the stronger multicells. ..Broyles.. 06/14/2025 $$ |
