It's spring, but it feels like summer
The numbers from the KALB-TV weather watchers network verify the unseasonable warmth we felt Tuesday. Readings were 10-17 degrees higher than is typical for mid-late March.
Why has the weather been so warm lately? The answer is high pressure aloft. Similar to a deep, warm bubble of air, the high has been dominating the central Louisiana weather pattern since the weekend with atypical warmth.
The warm air focused on portions of Natchitoches, Winn, and Grant Parishes Tuesday. You can see part of that pattern with the 89 at Colfax and 88 at Winnfield. Other readings in these parishes were comparable: Bellwood and Packton hit 89 degrees. This type of behavior is common with these warm, upper-level highs-the heat will focus in relatively small areas.
The high's day are numbered, however, as a strong disturbance moves eastward across the southern Rockies and Plains later this week and heads toward the lower Mississippi River Valley. As the disturbance destroys the ridge, rain and thunderstorms will occur with potential for severe weather late Friday into Saturday.
