Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1208 PM CDT Mon May 01 2017 Valid 021200Z - 031200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE MIDDLE TO UPPER TEXAS COAST... ...SUMMARY... Thunderstorms will be possible from the western Gulf Coast to the northern Plains through Tuesday night. A few thunderstorms with hail or strong wind gusts may develop late Tuesday night near the central to upper Texas Coast. ...Middle to Upper Texas Coast... An upper-level trough will amplify and move southeastward across the intermountain west into the southern and central Rockies from Tuesday into Tuesday night. A 40 to 55 kt low-level jet will develop in the southern Plains ahead of the trough resulting in strong moisture advection across the southern half of Texas. Surface dewpoints are forecast to increase into the upper 60s and lower 70s F across the Texas Coastal Plains with moderate instability developing during the overnight period. This combined with lift associated with warm advection and moderate deep-layer shear should be enough for a marginal severe threat late in the period in and to the west of the Houston area. Strong wind gusts and hail will be the primary threats with the greatest potential in the 09Z to 12Z timeframe early Wednesday morning. ..Broyles.. 05/01/2017Read more
