As many head back to work and school, our weather pattern digs into a state of normal for the week ahead.
Forecast Discussion: Small variances in the upper level pressures and temperatures will interact with a weak area of high pressure along the east coast to send impulses of energy through our region. Meanwhile, a steady southeasterly surface wind flow will... more »

Unchanging average September weather is expected for the week ahead.
Forecast Discussion: The upper level trough that activated showers and thunderstorms this weekend is flattening out. It is a dip in pressures and temperatures aloft from west to east that cause the atmosphere to churn and lift air. Those lifting motions in turn create showers and storms. As the trough flattens,... more »

Things are finally starting to settle down. 100% of the viewing area saw measurable rainfall today, and some areas saw heavy rain. We saw 1.39 inches at the Baton Rouge airport, which was nowhere near our record of over 4 inches for this day in 1991. The southwest part of the state including St. Mary Parish in our viewing area... more »

Aided by tropical moisture, a storm system will bring heavy rain to some spots this weekend.
Forecast Discussion: An upper level trough advancing eastward out of the Rocky Mountain West will generate the needed uplift and forcing to enhance shower and thunderstorm development late Friday and especially Saturday. Moreover, the remains of Invest 98L in the Gulf will inject more moisture... more »

Heading into a long weekend, outdoor planners will have to monitor the forecast closely.
Forecast Discussion: The week will round out in typical August fashion with warmth and humidity each day before afternoon showers and thunderstorms develop. By Late Friday and Saturday though, an upper level trough to the west plus a broad high pressure in the Mid-Atlantic, will kick up... more »

Over the next several days, the weather pattern will gradually become more active.
Forecast Discussion: The upper level trough of low pressure that spawned Monday's round of thunderstorms continues to sag southwestward into the Gulf of Mexico. Actually, the National Hurricane Center is monitoring it as a potential area for spin up of a weak tropical low-nothing too concerning for the... more »

Far fewer thunderstorms are expected Tuesday Afternoon than what was found on Monday.
Forecast Discussion: An upper level low pressure system and weak surface boundary that triggered widespread shower and storm activity on Monday Afternoon has passed by to the west and the resulting lack of uplift will mean fewer showers and thunderstorms for Tuesday. Closer to the low, a few... more »

The oppressive heat will be quelled this afternoon by a batch of showers and thunderstorms.
Forecast Discussion: A weak boundary stalled in the northern Gulf of Mexico, combined with an upper level disturbance will set off showers and thunderstorms on Monday. The two will combine to greatly enhance uplift around the region and with such hot and humid air in place... more »

Things are beginning to cool down, and we can expect rain again in the forecast for Monday. As an impulse pushes this way from Georgia, that will spin up showers and thunderstorms on Monday. That is our best chance for rain. Tuesday and Wednesday look a little dry, but we're keeping some rain chances in the forecast as we get... more »

Well, relatively speaking, we've been on the cool side this year, but with temperatures reaching the upper 90s, we are looking at the hottest weekend of the year thus far. August is typically the hottest month in Louisiana.
An area of high pressure parked right over us will be keeping rain chances low, while raising temperatures and pumping in that extra... more »

After many hot days in a row, thermometers will take a further turn upwards today.
Forecast Discussion: A ridge of higher pressure and temperature aloft will build into the region while a surface high pressure system sets up in Southern Louisiana. The ridge will promote a warmer, more stable atmosphere and overall sinking motion in our atmosphere. Such processes will inhibit... more »
