National Weather Service Nashville TN
127 PM CDT TUE SEP 20 2016

.DISCUSSION...

Upper ridge will continue to build in this direction out of the
southern plains for the remainder of this week and over the
weekend keeping dry weather across our area as carolina system
continues to waddle around before finally getting picked up by
northeast, mid Atlantic upper trough that develops late in the
work week and lifts it out early this weekend. Upper ridge
dominates Middle Tennessee weather right through the weekend and
into at least the first of next week and this means above normal
temperatures during this period.

.Climate...Nashville is averaging 4.9 degrees above normal so far
this month with Clarksville averaging 3.4 degrees above normal and
Crossville 3.7 degrees above normal. Rainfall at Nashville has
totaled 1.64 inches so far this month which is 0.46 inch below
normal. Clarksville has measured 1.29 inches which is 0.87 below
normal while Crossville has totaled only 0.82 inch which is 1.60
below normal.

Nashville averages 47 days with 90 degrees and above. The most
ever is 96 days back in 1954.

The ranking goes like this for days 90 and above:

1954...96 most ever

1944...79
1953...78
