Area Forecast Discussion
National Weather Service Huntsville AL
243 AM CDT Sat Jun 6 2020

.NEAR TERM...(Today)
Issued at 242 AM CDT Sat Jun 6 2020

This morning will start off with some foggy conditions across the TN
Valley. A few spots could see patchy dense fog so use extra caution
when driving. Fog should dissipate around 8-9am.

A ridge of high pressure will build in across the Southern Plains and
into the Midwest today before slowly sliding eastward. This will keep
conditions dry, however with a boundary lingering to our south, a
very isolated shower/storm mainly south of the TN River could develop this
afternoon. We were able to reach the 90`s yesterday in a few
locations and expect daytime highs around 90 degrees across the TN
Valley today.

.SHORT TERM...(Tonight through Monday)
Issued at 242 AM CDT Sat Jun 6 2020

Overnight lows will only fall towards 70 degrees, and with mostly
clear skies along with nearly calm conditions, patchy fog is
possible once again.

The previously mentioned ridge will build eastward on Sunday keeping
conditions dry, and temps a tad warmer reaching the lower 90s. As
TS Cristobal slides closer to the Gulf coast on Sunday, will start to
see southeasterly winds pick up with speeds around 10kts in NW AL
compared to ~5kts in NE AL. As Cristobal moves inland on Monday,
winds will increase a little bit more becoming 10-15kts with gusts
~20kts across NW AL. Will see some associated rainfall from it`s
outer bands start to reach the forecast area Monday afternoon where
isolated to scattered thunderstorms are possible. Cloud cover will
start to increase from south to north on Sunday and continue through
Monday as the TS approaches. The cloud cover and rainfall will keep
temps a few degrees lower on Monday with daytime highs reaching the
lower 80s.

.LONG TERM...(Monday night through Friday)
Issued at 242 AM CDT Sat Jun 6 2020

Showers and thunderstorms associated with the outer bands of TS
Cristobal will begin to enter the forecast area on Monday
afternoon/evening. The center of the circulation will rapidly move
northward across LA and MS on Tuesday, which will keep the bulk of
the heavy rain to our west. By Tuesday night, the remnants of
Cristobal will be absorbed in an eastward advancing shortwave trough
located across the northern Plains into the upper Midwest with a cold
front to the south of the trough. While the impacts in our area will
be minimal from the tropical system, a wet pattern will continue
through the middle of the week before the aforementioned cold front
swings through the area on Wednesday night. Ahead of the front,
strong low and mid level southerly flow will advect moisture in from
the Gulf of Mexico northward across AL and as a result rain and
thunderstorms are likely throughout the day Tuesday and Wednesday.
Hot and dry weather returns post frontal system for the second half
of the work week with afternoon highs in the mid 80s.


.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1057 PM CDT Fri Jun 5 2020

Periods of high cirrus will continue to stream in from the southwest
tonight. Even so, calm winds will allow for fog development near the
terminals, some of which may result in IFR or worse visibilities. Fog
mixes out early this morning, leaving behind mostly clear skies and
light winds.
