RAH - Sunday afternoon update.
By Thursday morning, we'll
see moist WSW flow aloft beginning to overrun the cold low level
airmass advecting into NC, thus many of the models have been
suggesting some light precip developing to our SW and skirting at
least our southern and southeast zones during the daytime and
evening Thursday. It's worth noting that the operational ECWMF has
been shifting the precip shield further and further south with
recent runs (given its further southward progression of the
aforementioned cold front). That said, if the GFS and Canadian
verify, which suggest that precip will fall farther north than what
the ECMWF shows, forecast soundings from these models suggest an
opportunity for some wet snowflakes to mix in with the otherwise
light rain over the south and southeast portions of our CWA. Clearly
there is a great deal of uncertainty with this part of the forecast,
so the best advice now is to stay tuned to future forecasts for
updates, but right now we are not forecasting anything that would
lead to substantial weather impacts for central NC later this week.
