SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0638 AM CST Fri Mar 07 2025 Valid 071300Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm development will be possible in parts of the Desert Southwest and southern Plains today into tonight. The potential for severe weather is expected to remain low. ...Synopsis... Water-vapor imagery this morning shows a mid-level low and associated trough over the lower CO Valley/Baja vicinity. Models show this mid-level low moving east into NM by late tonight. In the low levels, a low initially over KS will move east along a frontal zone and weaken as it moves into the lower OH Valley. A trailing cold front will push southward into central TX by daybreak Saturday. A weak area of low pressure will move from NM into the Edwards Plateau tonight. Southerly low-level flow/warm air advection around 850 mb will act to moisten profiles from central/north TX into southern OK during the 08/09-12 UTC period. Forecast soundings over western north TX show cold 500-mb temperatures (around -20 deg C) and upwards of 500-1000 MUCAPE. Isolated to widely scattered showers and a few elevated thunderstorms are possible. The majority of members from the latest convection-allowing model guidance (e.g., 00 UTC HREF, MPAS) imply limited storm intensity. The strong effective shear/cold mid-level temperatures could support hail with the stronger elevated cells, but the severe threat is currently expected to be low. ..Smith/Dean.. 03/07/2025
