.UPDATE...
Issued at 830 PM CST Thu Jan 9 2025
Have updated the short-term grids with the most recent model data
and there`s no appreciable change in the forecast. We are still
expecting widespread amounts of 4-7". Some locations will likely
exceed that range. Other locations, mainly our southern areas near
the TN/AL border, can expect less than 4", but also with light ice
accumulations. Either way, the impacts are going to be the same
area-wide. Radar imagery shows the leading edge of the snow just
now reaching the Memphis Metro Area. The environment across Middle
Tennessee is still relatively dry. Dew points are mostly in the
teens, and the evening sounding from OHX gives a Precipitable
Water of just 0.16", which is actually below the 10th percentile
for this date. So we`re going to need quite a bit of moisture
advection in order for precipitation to start reaching the
ground. That should happen rather quickly now that the upper ridge
has passed east of Middle Tennessee and the upper flow is in the
process of turning southwestward. The forecast is still on track.
