Sounding discussion...

The 00z sounding shows some marginal instability as indicated by
MLCAPE values of 619 j/kg and mid-level lapse rates right at
6.0c/km. However, this instability has had very little moisture to
work with as indicated by the unseasonably low precipitable water
value of 1.5 inches. This dry air mass is advecting in from the
north on the back of deep layer northeast flow extending
throughout the atmospheric column. Overall, other than the slight
increase in instability due to daytime heating there has been
little change in the airmass since the sounding 12 hours prior. 32
