A deep dip in the jetstream swept over central Louisiana Tuesday and brought an uncommon mixture of weather.
Initially, the day began chilly with lows in the lower 40s to the lower 50s. Natchez, Miss. was the cool spot with a low of 42 degrees. Winnfield and Fairfield reported 43 degrees. Oberlin reported the warmest reading with 51 degrees. The long-term daily average is 52 and the record is 32 in 1971.
Afternoon highs ranged from the middle 60s to the lower 70s. Natchez, Miss. reached 64 degrees for the lowest afternoon high while Oakdale and Anacoco hit 73. The long-term daily average is 76 and the record is 89 in 2011.
Very cold air aloft was associated with the trough aloft. When combined with the modest daytime surface heating, an unstable atmosphere resulted. In fact, reports of small hail were received in the First Alert Storm Center office from Vidalia, near Marksville, Bunkie, east of Winnfield, Cloutierville, and Plaucheville. Strong wind was also reported, with gust of 35-45 mph reported at local airports with reliable wind instruments. Rainfall was not impressive, with Winnfield the highest total at 0.39 inches. Bunkie had 0.36, and Marksville 0.30 inches.
Wednesday will be a much more settled day with plentiful sunshine.
