Gotta get back to court, but here's thinking of all of ya!
Mesoscale Discussion 0126
NWS Storm Prediction Center Norman OK
0301 PM CST Thu Feb 20 2020
Areas affected...Parts of northeastern North Carolina and
southeastern Virginia
Concerning...Heavy snow
Valid 202101Z - 210000Z
SUMMARY...Snow, occasionally at heavy rates near or in excess of 1
inch per hour, appears increasingly probable within a corridor
across the North Carolina piedmont into southeast
Virginia/northeastern North Carolina Tidewater region by 6-7 PM EST.
DISCUSSION...Large-scale ascent, downstream of a low-amplitude short
wave trough digging into the lower Ohio Valley, is supporting a
broad shield of precipitation now overspreading a stalled or slowly
moving frontal zone extending across much of the Southeast. With
the continuing east-southeastward progression of the mid-level
impulse, models indicate that a surface frontal wave will gradually
deepen east of the Carolina coast through early evening, while
lower/mid tropospheric frontogenesis intensifies across the southern
Mid Atlantic Coast region.
Across the North Carolina coastal plain into the Tidewater of
northeastern North Carolina and southeastern Virgnia, the latest
Rapid Refresh suggests that lift will become increasingly maximized
in the mixed-phase layer supportive of large dendritic ice crystal
growth. While forecast soundings suggest that temperature profiles,
particularly near the surface and perhaps within a layer between
850-700 mb, are still marginal for snow reaching the surface across
much of this corridor, modification is ongoing in response to
evaporative cooling and melting of precipitation. This will
continue as precipitation persists and rates intensify.
Aided by the onset of diurnal boundary layer cooling, and perhaps
weak low-level cold advection in the wake of the frontal wave, a
transition to snow appears probable by 23-00Z, if not before, along
a corridor extending from roughly the Raleigh NC metropolitan area
into the Hampton Roads vicinity. It appears that this probably will
include general snow rates in excess of 1/2 inch per hour, with
rates occasionally on the order of 1 inch per hour in one or more
developing narrow heavier bands, which may continue into mid/late
evening.

Sleet fest 2020 well underway, finally mixed out the RN, now just need to start mixing SN. 0.22" and counting wasted on a mixed bag, 35.6/34.9

Snowing here although the rates are less than desirable..
+SN. Shaded grass is whitening.
I know I know!!! I'm way too excited! It is POURING huge flakes. Some are HUGE!! Pretty much straight up snow only.
Heavy snow here, starting to get patchy grassy accumulation
Can't remember the last winter MD I was under. Still coming down good here.

This would be 1/2-3/4 in per hour rate if we're not losing some of it to warm soil. But... it's accumulating some on grass. Already sticking on our cars, mulch, and pine needles.

106.1 said the snow will exit around 6PM, so we have a few more hours to get some accumulations. Dusting now, maybe we get to 1.5, 2 at the top.
