SHORT TERM /Tonight through Monday Night/...
Ridge of high pressure dominating period as it slides southeast into
the region. Remnants of cold advection stratocu in the far north
should continue to clear out late this afternoon with strong
subsident flow. With gradient winds set to lax overnight under clear
skies, the radiational cooling component will take over from the
advection process and allow for widespread locations reaching the
freezing mark. The previous Freeze Warning looks on track with the
fcst so no changes have been made. This may very well be the last
Warning of the season for the CWA based on agricultural interest
since Nov 20 is usually the end of the Watch/Warning/Advisory
issuances.

Winds quickly shift out of the SE for Monday as the center of the
aforementioned high shifts quickly off the mid-Atlantic coast.
Should still be a below normal temp day, though will feel much more
pleasant compared to today with less winds and temps moderating back
close to the upper 50s/low 60s. With this shift in the low level
fetch and a quick transition from NW flow aloft to amplifying SW
flow east of a developing northern Gulf trough, we should see some
moisture return off the Atlantic coast Monday night, which should
allow for a low level cloud deck pushing in across the southern
majority of the area after midnight.

LONG TERM /Tuesday through Sunday/...
No major changes needed for the extended portion of the forecast.
Have only made some minor tweaks to the pops for Thanksgiving as the
models have become into slightly better agreement.

Both the ECMWF and GFS have come in a bit drier for Thanksgiving.
Models do have some slight timing and synoptic pattern differences,
but both keep a surface low pressure well to the south of the CWFA.
Have tweaked pops downward across the southern CWFA, but in reality
most areas went from around 30 percent to 20 percent.
