Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Nashville Tennessee
125 am CST Monday Jan 26 2015
Mesoscale update...making some changes for the early morning
hours. Radar shows light precipitation east of I 65...with just
some patchy drizzle to the west. Not seeing any more upstream...so
removed precipitation altogether for our northwest counties. Lowered probability of precipitation
elsewhere...and backed off on snow for parts of the area. We will
show a mix just for the upper Cumberland and parts of the Highland
Rim. Low level temperatures are too warm elsewhere...and when the colder
air does move in around daybreak...moisture will be too shallow
for much Snowflake production.
Along with the light mix for the high elevations...some patchy
freezing drizzle is possible from daybreak through middle morning.
The highest elevations of the plateau from Jamestown to Monterey could
still pick up one half inch of snow between daybreak and middle morning.
Previous discussion... /issued 1137 PM CST sun Jan 25 2015/
radar imagery indicates light shower activity is progressing
through the area...with forecast soundings depicting light
precipitation for the first half of the taf period. Expect a
transition from rain to snow...or possibly drizzle...though it is
doubtful it will be an impact to visible. Ceilings will remain
low...degrading to IFR early...then improving to MVFR between 12z
