AREA FORECAST DISCUSSION
National Weather Service Morristown TN
1105 AM EDT Sun Mar 28 2021

.UPDATE...
MORNING UPDATE.

&&

.DISCUSSION...
Precip finally making an exit to the east and cold front sweeping
through area now west to east. Should have gusty winds this
afternoon across the area as High Pressure fills in. Wind
advisory continues in the mountains until 2pm. These stronger
winds are mainly a pre-frontal threat, so frontal passage will
offer some gusty winds, but for the higher elevations, the winds
will actually decrease, so 2pm expiration looks fine.

Temperatures will likely be dropping this afternoon as the cooler
air moves in--might be offset by diurnal heating somewhat, but
will take a while for clouds to erode from the west, so even
diurnal heating will be muted.

&&

.AVIATION...
12Z TAF DISCUSSION.

For the next hour, a line of showers and some embedded
thunderstorms will move east of the terminals. Lower ceilings and
visibilities will continue mainly MVFR conditions but possibly
IFR for an hour. Showers will persist through late morning behind
initial line with mainly MVFR conditions. Gusty west to northwest
winds to about 20 knots will continue through most of the day.
Skies will begin to clear from the southwest between about 18 and
00Z. VFR conditions from about 22Z through the end of the TAF
period with winds decreasing after 00Z this evening.
