Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0213 AM CST Sun Jan 15 2017 Valid 171200Z - 181200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE LOWER TO MIDDLE TEXAS COAST... ...SUMMARY... A marginal severe threat will be possible in the Texas Coastal Plains near and to the north of Corpus Christi, Texas on Tuesday. ...Lower to Middle Texas Coastal Plains... An upper-level low near Baja California is forecast to move slowly eastward on Tuesday as southwest mid-level flow remains located across the southern Plains. A cold front is forecast to move slowly southward to the lower to middle Texas coast by Tuesday afternoon with surface dewpoints in the coastal areas remaining in the 60s F. Some instability may develop by afternoon south of the front mainly in the vicinity of Corpus Christi. NAM forecast soundings in this area at 21Z on Tuesday show surface dewpoints in the mid 60s F, SBCAPE near 500 J/kg and 0-6 km shear of 55 to 60 kts. This may be enough for a potential for hail and marginally severe wind gusts with surface based storms that develop along and just to the south of the front. The area with the greatest potential for marginally severe convection will depend upon the exact position of the cold front by Tuesday afternoon. ..Broyles.. 01/15/2017Read more
