Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sun Jul 02 2023 06:01:03 ACUS02 KWNS 020600 SWODY2 SPC AC 020559 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1259 AM CDT Sun Jul 02 2023 Valid 031200Z - 041200Z ....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS/NORTHERN INTERMOUNTAIN REGION...AND PORTIONS OF THE EASTERN AND SOUTHEASTERN STATES... ....SUMMARY... Scattered severe storms will be possible across portions of the north-central U.S. and into the northern Intermountain region Monday. Severe storms are also expected from southern New England and the East Coast states westward across parts of the Southeast. ....Northern Intermountain region/northern Plains... As cyclonic flow aloft expands southward across the region south of an upper low crossing the Canadian Prairie, small-scale disturbances within the flow are forecast to shift across the northern Rockies and northern Plains Monday. As an attendant cold front shifts slowly southeastward across the northern Plains and southward across Montana, daytime heating of a moist boundary layer will yield a zone of moderate destabilization roughly along the frontal zone. Subsequently, isolated to scattered afternoon storm development is expected, with potential for clustering/upscale growth during the evening as a High-Plains low-level jet develops. With a belt of 40 to 50 kt cyclonic/westerly flow near and to the cool side of the front, organized/rotating storms are expected initially, with large hail and damaging winds expected. Overnight, damaging wind potential will likely continue -- particularly from the northern High Plains into the Dakotas -- as the potentially upscale-growing storms persist through the evening and into the overnight hours. ....Southern New England southward across the East Coast States, and westward to the Tennessee Valley/Gulf Coast states... Daytime heating of a moist boundary layer ahead of a weak/rather ill-defined cold front moving eastward across New England and the East Coast states, and southward across the Tennessee Valley, will result in moderate destabilization. As a result, convective development is expected to commence by early afternoon, with scattered to numerous thunderstorms expected by late afternoon. While modest flow -- and thus generally disorganized/pulse-type storms -- can be expected across the central Gulf Coast states, a belt of enhanced mid-level west-southwesterlies is forecast from the central/southern Appalachians to the Mid-Atlantic region during the afternoon. Therefore, it appears that severe-weather risk -- primarily in the form of damaging winds and hail -- will be maximized across portions of the Carolinas and Mid-Atlantic Region, during the afternoon and into the early evening hours. ...Goss.. 07/02/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
