Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Jul 06 2023 06:06:15 ACUS02 KWNS 060606 SWODY2 SPC AC 060604 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0104 AM CDT Thu Jul 06 2023 Valid 071200Z - 081200Z ....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CENTRAL HIGH PLAINS VICINITY EASTWARD TO WESTERN PARTS OF MISSOURI AND NORTHWESTERN ARKANSAS... ....SUMMARY... Scattered strong/severe storms are expected across central portions of the country on Friday. ....Central Plains and vicinity... Thunderstorms are forecast to be ongoing across portions of the central Plains and southward into Oklahoma at the start of the period, in the form of one or more weakening MCSs. Some severe threat may linger during early parts of the period, but should diminish through the morning. By afternoon, re-initiation of storms is expected, along remnant outflows as well as westward into the southern High Plains in an upslope-flow regime. With moderate destabilization expected through peak heating in areas away from ongoing clouds/convection, and aided by 35 to 45 kt mid-level flow, storms should organize locally, with potential for large hail and damaging wind gusts. Overnight, potential for storms to grow upscale into clusters is expected, which would result in continued severe potential. Some models hint that MCS potential may extend as far east as the Mid-Mississippi Valley/Illinois late in the period. ....Northern Plains... A cold front is forecast to shift southward across northern Minnesota and North Dakota during the day Friday. Modest destabilization is expected through the afternoon, limited by scant boundary-layer moisture. However, the limited moisture also suggests a rather deep mixed layer, which could support a few gusts to severe levels with stronger storms, through early evening. ....The Northeast... A weak cold front is progged to progress eastward across the northeastern U.S. Friday. Ahead of the front, a moist airmass will modestly destabilize through the afternoon, supporting scattered storms, with a few clusters or bands of convection possibly evolving. Still, shear will remain fairly weak (mid-level flow generally at or below 25 kt across the warm sector), suggesting storms will remain generally disorganized. A few stronger gusts in the 40 to 50 MPH range will be possible, through late afternoon. ...Goss.. 07/06/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
