.PREV DISCUSSION... /ISSUED 1010 AM CST Mon Jan 23 2017/

A deep upper low will continue to track eastward across the Mid
Atlantic states today, providing cool temperatures aloft and
marginal instability for a few thunderstorms.  Scattered showers and
thunderstorms will also be possible over parts of the southwest US
as strong onshore flow and several embedded shortwave troughs affect
the region.  Severe storms are not anticipated in either of these
areas.
