Day 1 Convective Outlook

0147 PM CST Fri Jan 27 2017
Valid 272000Z - 281200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected across the contiguous United States
through tonight.
No changes are made to the outlook for this issuance.
..Broyles.. 01/27/2017
.PREV DISCUSSION... /ISSUED 1025 AM CST Fri Jan 27 2017/
...Discussion...
A continental-polar air mass extending through much of the Gulf
should preclude thunderstorm potential. Modest low-level warm-air
advection tonight should result in elevated showers developing from
the Edwards Plateau to south Texas. Buoyancy and instability should
remain too weak to support charge separation.
