CTP's thoughts for Friday.....
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Clipper moving across the Great Lakes on Fri should produce a
little light snow, but does not look like a significant
snowfall. However, the GFS has the sharpest part of the upper
trough passing overhead late Fri/early Fri night. Temps are
already cold, but depending on timing, SNSQ are possible, esp if
the forcing arrives mid-aftn. The air mass behind the clipper
system is very cold, and we have made sure to stay on the low
side of guidance for temps Sat- Sun night. Sun night may be the
coldest as the sfc ridge will be cresting overhead and lake
effect clouds will be going away.
