January 19, 2000 (1:00PM)
Finaaly, our first measurable snowfall of the 1999-2000 winter
season will come to fruition tomorrow as a period of light to
possibly moderate snow will envelop the region by daybreak
on Thursday. Jan 19 0Z models runs seemed relatively
unimpressive for our area, but the 12Z runs proved to
be a bit more touch and go. The ETA, which was most
unimpressive in my opinion last night, came back strong
this afternoon developing the secondary much closer to
the coast and drilling areas like Boston and Cape Cod. The
NGM continued to drop decent QPF's in our area today as well
did the AVN to an extent, then the NGP to an even
lesser extent. But rather than disect every single model
and nail down the differences, let's use them
merely as guidance here. We are now into the point of
nowcasting, so let's see how this should unfold as of
now. Tonight should be calm and seasonable. We will
see increasing clouds with lows in the mid 20's. Light
snow should break out by daybreak or roughly sometime between
5 and 7 AM. It should remain light most of the day and
may even stop for a point. Later in the afternoon, we
may begin to pick up more moderate snowfall as temps
hover in the lower 30's. By this point, a secondary low
is really getting cranking somewhere off the DelMarVa
peninsula. Coastal areas south and east stand to see
a decent dumping of the white stuff, so it's a little too
early to be specific for them, but I feel that up to
six inches is possible in a few coastal sections.
Snow should taper to flurries late tomorrow night, winds
should really beging to howl, and the temperature will
nosedive. Friday's high temperatures could be just as cold
as what we saw earlier in the week. So, all in all,
tomorrow looks messy, more for the commute home than into
work. Total accumulations the way I see it now for
Delaware County: 2-4 inches of snow. There are still a
few runs of the models left, so this number could be
adjusted either up or down, but looks good right now.
Check back later this afternoon for an update. Take care!
