SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1205 PM CDT Fri Oct 31 2025 Valid 011200Z - 021200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS COASTAL TEXAS... ...SUMMARY... Strong to isolated severe storms capable of large hail will be possible on Saturday late afternoon/evening across portions of Coastal Texas. ...Synopsis... A positively tilted mid-level trough will amplify as it moves across the southern Plains on Saturday. A cold front will accompany this trough and race south across Texas during the day. Low-level moisture will remain mostly offshore, but at least some deeper moisture may push a few counties inland across the Texas coastal counties. ...Texas Coast... Mostly weak instability is forecast to develop across coastal areas of south and southeast Texas on Saturday morning and afternoon as temperatures warm into the 70s with dewpoints potentially as high as the low 60s. A significant warm nose between 850 and 700mb will suppress convection for much of the day. However, by late afternoon/early evening, as forcing increases ahead of the approaching trough and with the southward moving cold front, expect inhibition to erode and scattered thunderstorms to develop. The greatest instability will likely remain offshore or right along the coast. Therefore, there is a relatively limited areal extent for storm maturity. Nonetheless, expect a few strong to isolated severe supercells to develop right along the coast with large hail as the primary threat. ..Bentley.. 10/31/2025
