I don't want to throw cold water on this - I want snow as much as anyone, but...
RAH is very skeptical. Of course, this was posted before 5AM,
but how much has changed to challenge their logic?
While many models continue to indicate the possibility of some
rather impressive snowfall accumulations, still thinking
accumulations and overall impacts will remain far less than the
numbers that the raw model solutions keep pushing out. Several
limiting factors will be at work, including: (1.) Persistent above
freezing surface temperatures that will help temper/melt the
majority of the snowfall. (2.) 10:1 snow to liquid ratios are not
likely in an event like this, expect closer to 5:1 or even less than
that. (3.) The parent high remains in an unfavorable climatological
location for delivery of efficient cold air. While there is some
indication that the high may break off to our north becoming a bit
more favorable, thinking that we`ll need to rely on a stronger than
anticipated bombing coastal low to truly get the cold air in place
in-time for a significant snowfall event. Another possibility would
be the presence of lower than anticipated surface dewpoints in place
Thursday afternoon and evening across central NC, which will promote
a more lucrative wet-bulb effect. A more reasonable, way-to-early
forecast would be closer to an inch on grassy and elevated surfaces
along and southeast of the I-95 corridor with a half inch or so
measured up to about the Triangle region. Elsewhere an exciting
trace amount would be prevalent.
