.DISCUSSION...
A strong cold front will continue to shift south through the remainder
of East Texas, Southern Arkansas, and North Louisiana this evening, ushering
much cooler and drier air into the area tonight through Saturday. A few
sprinkles may accompany the front and behind it tonight, with a return to
more seasonal conditions is expected areawide Saturday. However, much lower
RH`s will return Saturday, as they fall to 20-30%. North-Northeast 20 ft
winds will increase to 15-20 mph with gusts to 30 mph behind the front later
this evening/overnight, persisting through the morning Saturday before gradually
relaxing to 10-15 mph with occasional higher gusts for the afternoon.
Winds should decouple after sunset Saturday as surface high pressure settles into
the area, although southerly 20 ft winds will return Sunday as this ridge
shifts east away from the region, resulting in a quick warming trend and a
gradual modification of humidities. However, min RH`s Sunday will remain
abnormally low at 30-35%, although southerly 20ft winds will remains 10 mph
or less through the day. Additional RH recovery is expected as we move into the
new work week, which will aid in the return to much above normal temperatures.
The potential will exist for the awaited return of scattered showers and
thunderstorms to the region Tuesday night and especially Wednesday, with the
period of unsettled weather expected to linger through the end of the work
week.

Fire Danger Statement
National Weather Service Shreveport LA
142 PM CDT Fri Mar 27 2026

...ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED FOR ALL OF OUR
FOUR STATE REGION WHICH INCLUDES EXTREME SOUTHEAST OKLAHOMA,
SOUTHWEST AND SOUTH-CENTRAL ARKANSAS, EAST TEXAS, AND NORTHERN AND
CENTRAL LOUISIANA...

Weather conditions will be favorable for wildfire growth.

* TIMING: From 11:00 AM Saturday Morning through 7:00 PM Saturday.

* RELATIVE HUMIDITY: Afternoon values will range from the 20 to 30
  percent range.

* WIND: Sustained northeast to east winds around 10-15 mph early
  in the day with gusts up to 20 mph. Winds will begin to weaken
  though during the afternoon hours, around the time RH values
  reach their minimum.


* FUELS: Critically dry.

These conditions will support the spread of wildfires. Outdoor
burning and activities that involve open sparks or flames are
discouraged. Please report all wildfires to local law enforcement
as soon as possible.

Fire Weather Parameter Definitions

Cloud Cover

Predominant cloud condition (e.g., cloudy, pcldy, clear).

Precip Type

Type of precipitation expected to occur such as rain, showers, thunderstorms.

Temp (24H Trend)

Forecast maximum or minimum temperatures in Fahrenheit with a 24-hour trend note in parenthesis.

RH % (24H Trend)

Forecast maximum or minimum relative humidity with a 24-hour trend noted in parenthesis.

20FT Wind (MPH)

20-foot wind speed (mph) and direction (eight compass points).

Precip Amount

Amount of liquid precipitation expected to the nearest hundredth (0.01).

Precip Duration

Number of hours measurable precipitation is expected to last.

Mixing Hgt (M - MSL)
and
Mixing Hgt (FT - MSL)

A projected height in meters or feet above mean sea level through which vigorous mixing will take place based on the maximum temperature on a given day. It is the height at which smoke will lose its buoyancy and stop rising. It is valid for the afternoon hours when temperature nears the predicted maximum.

Transport Wnd (M/S)
and
Transport Wnd (MPH)

The predicted average wind in meters per second or miles per hour in the layer below the mixing height near the predicted maximum (usually in the afternoon).

Vent Index

The Ventilation Index parameter is obtained by multiplying the mixing height in meters times the wind speed in meters per second.

Cat Day

The Vent Index corresponds to a Catgeory Day.

< 2000	1
2000 - 3999	2
4000 - 7999	3
8000 - 16,000	4
> 16,000	5

Mix Hgt 500

The temperature in Fahrenheit needed to achieve a mixing height of 500 meters. If the expected high temperature is cooler than the 500 meter mixing height temperature, then the mixing height parameter above will be less than 500 meters.

Stability Class

The stability class based on wind, incoming solar radiation (sun angle), and cloud cover. The more unstable the forecast stability class, the more readiliy a pollutant is dispersed.

Stability Class Description
A	Extremely Unstable
B	Unstable
C	Slightly Unstable
D	Neutral
E	Slightly Stable
F	Stable
