morning AFD from LWX about the "event"
Thursday looks to be our next chance at any impactful weather. A
emerging shortwave trough will deepen over the Central Plains
as a surface low develops over the TN Valley. With the jet
stream orientated in a SW to NE trajectory, patten looks
indicative for a Miller B type of system: where an emerging low
out of the TN/OH valley phases its energy with a developing low
off Cape Hatteras. Guidance has been pretty persist on this set-
up, resulting in a quick moving snow event. While not expecting
amounts to be as drastic as they were yesterday at this time, do
think this system is capable of producing a more widespread
1-3" or 2-4" event with locally higher amounts possible along
the higher terrain due to upslope processes. Given the fact that
this is still a few days away, the forecast is subject to
change and confidence on any definitive outcome still remains
low at this time. However, confidence is increasing for the
possibility of a low end, plowable event. Best estimate for
timing at this juncture would be late Thursday night into Friday
morning, which would make traveling for the Friday morning
commute hazardous.
