A strong disturbance aloft in the southern jetstream triggered significant rain again today. That feature also helped push another cold front through the area.
Thermometers across central Louisiana showed a wide range of temperatures today. Southern locations felt the warm sector as temperatures soared to 68 at Grand Coteau and 67 at Opelousas. In contrast, Portions of Winn, Natchitoches, and Sabine Parishes never experienced the warm front. Readings there stayed in the lower 40s all day.
The upper-level disturbance tapped good quality moisture and produced significant rainfall. Down Highway 1 near River View Church, two inches fell. Lecompte measured 1.80; Simpson 1.77; and Oakdale 1.70. Nickel-size hail fell briefly at Simpson in a thunderstorm.
The disturbance has passed to our north and east and Wednesday's weather will settle down. However, a second, reinforcing cold front will arrive early and will strengthen the grip the cold air has help lately.
