Advisory, which is in effect from 11 AM this morning to 7 PM CDT
this evening. 

* TIMING...11 AM CDT through 7 PM CDT Friday.

* WINDS...Southwest winds 20 to 30 mph with gusts up to 40 mph.

* IMPACTS...Lightweight objects such as trash cans and patio 
  furniture will be easily blown about by the gusty south winds. 
  In addition, high-profile vehicles traveling east to west on 
  highways and interstates will be subject to very gusty 
  crosswinds. Finally, open waters on area lakes will be 
  dangerous and very choppy. Use extreme caution. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Wind Advisory means that sustained winds of at least 20 to
30 mph are expected. Winds this strong can make driving

wish to take action to secure trash cans...lawn furniture...and
other lightweight outdoor objects that may be blown around in the
strong winds.

Area Forecast Discussion...UPDATED
National Weather Service Fort Worth TX
1210 AM CDT Fri Mar 24 2017

.AVIATION...
Stratus will spread north from South Texas on a 50-knot low-
level jet. Expect MVFR ceilings to move into Waco 06-07z and into
the Metroplex 08-09z. As an upper level trough and surface
dryline approach from the west, scattered showers and a few
thunderstorms may reach the I-35 corridor before daybreak. The
atmosphere is expected to be capped, so for now have just included
VCSH for the 11-16Z period. The stratus will be quickly swept to
the east as the dryline passes. Winds will shift to the southwest
at 15-25 knots. Some gusts over 30 knots behind the dryline. The
gusts should die off toward sunset Friday. As Pacific cold front
moves through the Metroplex Friday evening, winds will shift to
the west northwest at around 15 knots.

.UPDATE...
Have extended the Wind Advisory for areas along and northwest of a
Cameron to Rockwall to Sherman line through 4 AM and just left the
rest of the Wind Advisory to expire at 1 AM. Sustained winds
of 20 to 30 mph continue across most of the forecast area and
as of 11 PM, there were some gusts to 40 mph. Wind speeds should
slowly decrease to 15 to 25 mph overnight.

.PREV DISCUSSION... /ISSUED 320 PM CDT Thu Mar 23 2017/
The current upper level pattern is defined mainly by an upper
level ridge near the MS Valley and an upper trough over the Four-
Corners region. At the surface, a strengthening lee-side cyclone
will keep the tight pressure gradient going, and the resulting
strong south winds should persist well into the evening. The wind
advisory will remain valid through 06Z tonight, and the evening
and overnight shifts can take a look at the possibility of
issuing another advisory if conditions look right tomorrow. At
this time, things look a little too borderline to issue this
early.

The strong south winds are advecting moisture northward across the
forecast area in advance of the storm system to our west. Surface
heating and strong dynamic forcing will generate convection later this
afternoon over the TX Panhandle and West-Central Texas. Activity
will likely be focused along a dryline, which will be forced
eastward as the upper trough moves east. Storms may initially
become severe, but will likely lose some of their intensity while
entering our west counties due to the lack of any appreciable
instability (mainly the result of the time of day). Still, some
gusty winds may occur (probably not any gustier than our Wind
Advisory winds from today) along with some occasional cloud to
ground lightning.

Showers and storms will cross the I-35 corridor pretty close to
Friday morning rush hour, and then begin to intensify while
moving into a more favorable convective environment across the
eastern third of the area. Damaging winds and hail will be the
primary threat Friday afternoon, mainly for areas along and east
of I-45/HWY 75.

Precipitation will work its way east of the forecast area Friday
evening, with cooler and drier air spreading in behind the dryline
and Pacific cold front. The primary concern across the western
portion of the forecast area will again be fire danger, which
will be near critical levels due to the warm, dry and windy
conditions. The Fire Weather Watch has been expanded to include
areas generally along and west of a line from Gainesville to
Granbury to Comanche. If conditions continue to look ideal for
rapidly spreading wildfires, a Red Flag Warning may eventually be
issued.

A fast-moving shortwave trough will cross the Southern Plains on
Sunday, bringing a quick round of convection to parts of the
region. The best mid-level lapse rates and moisture will exist
over the northeastern counties, which is where POPs will be
highest. Rain chances will be mainly Sunday Night, and will
decrease the farther southwest you go.

A brief period of shortwave ridging aloft will bring nice weather
to the area late Monday and Tuesday. A slower-moving and deeper
upper low is then progged to cross the Desert Southwest Wednesday
and into West-Central Texas Wednesday night. This system has the
potential to bring some much needed and more widespread rainfall
as it taps into deep Gulf moisture. Depending on how much
instability and shear we can muster, there may also be some
windows for severe weather. But it's still a bit too early to rely
on convective parameters which may change from model run to model
run. Either way it looks like we are in for a fairly active and
progressive pattern for the next week.

This Hazardous Weather Outlook is for North and Central Texas.

.DAY ONE...Tonight.
Windy conditions will continue across the western two thirds of the
region through 4 AM with south winds in the 20 to 30 mph range with
some gusts up to 40 mph possible.

Thunderstorms will approach from the west late tonight, potentially
reaching the I-35 corridor before daybreak. However, with a strong
cap remaining in place, severe storms are unlikely. Any storm that
does develop overnight may contain gusty winds and cloud to ground
lightning.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
Thunderstorms will spread from west to east through the morning
Friday. As the storms move east of the Interstate 35 corridor early
Friday afternoon they may increase in intensity as they encounter
unstable air. Some strong to severe storms will be possible with
strong winds and large hail the primary hazards. All storms will
move into East Texas Friday evening.

The fire threat may reach critical levels Friday afternoon along and
west of a line from Gainesville to Granbury to Comanche where windy
and dry conditions are expected.

The next chance for thunderstorms will be Sunday afternoon through
Sunday night. Some of these storms could become severe. At this
time, the main hazards appear to be damaging straight-line winds and
large hail. The gusty winds associated with this system may
re-aggravate fire weather concerns Sunday afternoon.

The active springlike pattern will persist, and thunderstorm chances
will return on Tuesday and increase on Wednesday as the next system
approaches.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not expected at this time.
