000 ACUS01 KWNS 061950 SWODY1 SPC AC 061948 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0248 PM CDT Mon Jul 06 2026 Valid 062000Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER MISSISSIPPI VALLEY...THE ARKLATEX...AND CENTRAL VIRGINIA INTO EXTREME NORTHERN NORTH CAROLINA... ...SUMMARY... Widely scattered severe thunderstorms capable of large hail and severe wind gusts remain possible across the eastern Dakotas and western Minnesota this afternoon and evening. Isolated to scattered damaging wind gusts will also be possible with the strongest storms in the southern Mid-Atlantic, Carolinas, and ArkLaTex regions. ...20Z Update... The previous forecast (see below) remains on track, with only minor changes made to the thunder and severe probabilities to reflect the latest observations and numerical guidance consensus. ..Squitieri.. 07/06/2026 .PREV DISCUSSION... /ISSUED 1128 AM CDT Mon Jul 06 2026/ ...MN/ND... Morning water vapory imagery shows a fast-moving shortwave trough over southern Manitoba, with its associated surface cold front sagging southward across ND. This front will serve as the focus for scattered thunderstorm development by mid-afternoon from northern MN into eastern ND. Strong heating ahead of the front and dewpoints near 70F will yield MLCAPE over 3000 J/kg. Forecast soundings show relatively steep mid-level lapse rates and favorable deep-layer shear for supercells capable of large hail and severe wind gusts. These storms may persist through the evening, spreading southward into central MN and eastern SD. ...Mid Atlantic/Carolinas... Another day of scattered afternoon thunderstorms will affect much of the Mid Atlantic and Carolinas region today. Vertical shear and steering flow is rather weak, suggesting storms will be poorly organized. However, strong heating and steep low-level lapse rates, combined with substantial CAPE in forecast soundings, suggest that the strongest cells will pose the risk of damaging wind gusts over a relatively broad area again today. ...AR/LA/OK/TX... Strong heating and ample low-level moisture will lead to scattered afternoon thunderstorms again today over much of AR, southeast OK, northeast TX, and northern LA. This is near a mid-level trough where lapse rates and mid-level temperatures are more favorable for robust up/downdrafts capable of damaging wind gusts. Have opted for a small SLGT risk for parts of this area where convective coverage appears highest. ...Northern UT into WY... Scattered high-based fast-moving thunderstorms are expected this afternoon over northern UT, moving northeastward into western and northern WY. The strongest of these cells will pose a risk of damaging wind gusts. $$
