Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1211 AM CST Fri Jan 29 2021 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the U.S. on Saturday. ...Synopsis... The deep shortwave trough currently off the West Coast is expected to move through central/southern CA and the Southwest today, reaching the southern High Plains by early Saturday. This system is then forecast to continue northeastward throughout the day Saturday, eventually reaching the mid MS Valley while also developing a closed mid-level circulation. Surface low associated with this system will likely be centered near the CO/KS/OK border intersection early Saturday, before moving eastward along the OK/KS border and deepening throughout the day. This low is then forecast to becoming increasingly occluded as it moves across the Lower MO Valley into the Mid MS Valley Saturday evening through Sunday morning. Strong moisture advection is anticipated ahead of this system and its attendant cold front across the southern Plains. However, cold and dry antecedent conditions and fast eastward progression of the shortwave will keep 60s dewpoints south over the TX coastal Plain, away from the steeper mid-level lapse rates farther north. Enough mid-level moisture is expected to reach the OK/KS and adjacent Ozark Plateau for isolated lightning flashes within the deeper elevated storms within the warm conveyor. ..Mosier.. 01/29/2021
