113 ACUS02 KWNS 131723 SWODY2 SPC AC 131722 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1122 AM CST Fri Dec 13 2024 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Saturday. ...Central/Southern Plains to the Lower Ohio Valley... An upper low will move from the central Plains to the Great Lakes on Saturday. A surface low will weaken through the day as this trough advances northeast. A sustained low-level jet will advance from the Ozarks to the Ohio Valley and provide ample ascent and elevated instability for thunderstorm activity through the day. Instability should remain too limited for any severe weather threat from this elevated convection. Weak surface heating across the ArkLaTex may be sufficient for a few surface-based storms. However, instability will be weak and ascent will mostly be focused north of this area. Therefore, no severe storms are anticipated. ...California to the Pacific Northwest... A trough approaching the Pacific coast on Saturday will result in scattered thunderstorm activity from southwest Washington to central California as cooler air aloft steepens lapse rates across the region. Overall, weak instability combined with relatively weak low-level flow should preclude any severe weather threat. A more focused low-level jet will result in stronger low-level flow across the central California Coast late Saturday morning into the early afternoon. However, during this period, forecast soundings indicate minimal to no instability which should preclude any severe weather concern. ..Bentley.. 12/13/2024 $$
