This Hazardous Weather Outlook is for North and Central Texas.

.DAY ONE...Tonight.

Low thunderstorm chances will return late tonight, generally towards
Palestine and Athens.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Thunderstorm chances will increase on Thursday, especially along and
east of the I-45/US-75 corridor as a surface front surges east
through the area late in the day. A few strong to briefly severe
storms will be possible during the afternoon and evening, accompanied
primarily by a risk of marginally severe hail.

Very windy conditions are expected Thursday, as a vigorous storm
system and strong cold front move across the area. North/northwest
winds around 30-35 mph, with gusts of 40-55 mph, are expected by
Thursday evening, especially towards western North Texas. Wind
speeds will slowly decrease early Friday but will remain gusty
through the day.

Rain is expected to mix with or change to a wet snow, possibly heavy
at times, generally along and west of a Jacksboro to Mineral Wells to
Lampasas line late Thursday. The highest potential for impactful
snow will likely exist from Thursday evening into early Friday
morning. Anywhere from a trace to around 4 inches of snow
accumulation is expected, generally on grassy and elevated surfaces.
Some slushy road accumulation will be possible in heavy snow, though.
A combination of strong winds and moderate/heavy snow may locally
reduce visibility below a half mile, creating very hazardous driving
conditions.

Some potential exists for a rain/snow mix to develop towards the I-35
corridor Friday morning. Although warm ground temperatures and
lighter precipitation rates should preclude significant impacts, a
low probability exists for a brief burst of moderate/heavy snow
around the time of the morning commute. Continue to closely monitor
the forecast.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.

...WIND ADVISORY REMAINS IN EFFECT FROM 3 PM THURSDAY TO NOON CST
FRIDAY...

* TIMING...3 PM Thursday to Noon Friday, with the highest winds
  expected Thursday evening into early Friday morning.

* WINDS...Northerly winds will increase to around 25 to 35 mph,
  with several gusts upwards of 40 to 45 mph. An isolated gust as
  high as 50 mph is possible.

* IMPACTS...Loose outdoor objects, such as decorations, will
  likely be blown about in the wind. Driving will become difficult
  on east-west oriented roads, especially for those in high-profile
  vehicles. A few falling tree branches will pose a hazard to
  those outside. Additionally, isolated power outages will be
  possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Strong winds with gusts to 50 mph are forecast to occur. These
winds will make driving difficult for all vehicles. Boaters
should stay off area lakes as waters will become very rough. Weak
trees may be blown over and some minor structural damage is also
possible. Residents should take action to ensure all lightweight
outdoor objects are secured.
