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.

.DISCUSSION...
Hot, humid, and mostly dry conditions will return today, with temperatures
climbing into the mid 90s to near 100 degrees once again, with the hottest
temperatures expected over East Texas. Isolated afternoon showers and a
few thunderstorms will be possible over portions of Western Louisiana and
portions of Deep East Texas, before diminishing around/shortly after sunset.
Min RH`s this afternoon will range from 30-40%, although some isolated locales
in Southeast Oklahoma and Southwest Arkansas may see lower min RH`s of 25-30%,
with variable 20ft winds around 5 mph. Good RH recovery is expected tonight,
with hot, humid, and dry conditions returning Sunday as min RH`s fall to 30-35%,
and 20ft winds become more south-southeast 5-10 mph. Upper level ridging will
shift east into the Mid-Mississippi Valley Monday, before shifting east into
the Tennessee Valley and Gulf Coast states by midweek, maintaining hot and
humid conditions over the region, with only minimal relief in the form of
isolated afternoon showers and thunderstorms possible over portions of Deep
East Texas and Northcentral Louisiana through next Friday.

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
