Click here to access the Weather Activity Planner. This is an experimental planning tool that provides specific weather forecast information based on the official National Weather Service forecast. Users will select from a list of weather elements, input a criteria range for the selected element (i.e., temperature between 65 degrees F and 80 degrees F), and then select a location on the map. A graph will appear illustrating at what times(s) the weather element criteria is met for the selected location. Users may select up to six different elements at a time. This tool is not intended to replace a spot forecast.

Fire Weather Planning Forecast for Southwest Arkansas...
Northwest Louisiana...East Texas...and Extreme Southeast Oklahoma
National Weather Service Shreveport LA
508 AM CDT Tue May 21 2019

.DISCUSSION...

Gusty south winds are expected today ahead of a squall line of
showers and embedded thunderstorms moving through the
Arklatex this morning through early afternoon. Farther southeast,
expect this line to hold off until between midday and late
afternoon. No fog is expected this morning, but low clouds will
be abundant this morning. Showers and embedded thunderstorms
should gradually shift off to the north tonight leaving lighter
south winds and mainly dry conditions tomorrow. Humidity will
be quite high today through tomorrow, but should trend downward
a bit for Thursday. Temperatures will cool down briefly in the
Arklatex behind the front later today into tonight, but will
rebound to above normal levels thereafter...and generally all
other areas will stay near to above normal for the next
several days.

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
