Good evening, many were anticipating snow this weekend, and did see the first measurable snowfall. Tonight I’m watching the chances of seeing our first measurable snowfall greater than an inch. First of all, the National Weather Service in Louisville has confidence that several areas tomorrow morning will get some intense snows, a Winter Weather Advisory is in place for most of the area.
Now… Let’s talk about the set-up. Hi-Res NAM shows some hitching snow bands moving into the area Thursday morning, mostly light snow, but you may experience periods of heavy snow at times. Several of these heavier bands of snow could put down an extra quick half inch to an inch of snow on top of the accumulating light snow. The front will also bring gusts of about 30-40 mph, which could cause near whiteout conditions on the roads. School closings and delays are likely to more across central and northern Kentucky.
Accumulations… It’s a very tricky forecast to grip, Snowfall ratios are around 5 to 1, which means that 1 in of rainfall would be equivalent to 5 inches of snow. Also, these bands will be isolated bands of heavy now, which makes it harder for models to pick where the most snow will fall. The latest NAM total precip shows the general areas that could anticipate more accumulation than others. With the potential water to snow equivalent, several spots could anticipate upwards to about 2” of snow.
However, the GFS pushes the heavier totals more to the north.
With that being said, I’m sticking with my forecast of 1-2” generally for the area. Could some get an impressive 3”? Possibly so. Areas south of I-64 can anticipate a coating-1”.
Also, the snow isn’t the only concern. Wind Chill readings are expected to be in the single digits and lower teens.
Scott County Schools, i’m giving a 7/11 on the Snowday chance tomorrow.
