It's midweek and a chill remain in the air from Monday's cold front. High pressure at the surface continues to keep central Louisiana in its grip. The result was that temperatures stayed below normal for another day.
The pattern of morning lows showed considerable variation. Lower readings prevailed in the western and northern areas while observers in the southern Parishes reported higher temperatures. Many, Peason Ridge, and Bellwood all dropped to 28 degrees, but Opelousas remained at 39. The reason for the difference was high/mid level cloudiness over the central and southern portions of the area. A strong disturbance aloft brought the clouds in Tuesday evening and they stayed most of the night.
The sky cleared nicely Wednesday afternoon and temperatures rebounded into the 50s. Both local airports saw 56 for a high. The average is 61 and during the heat wave of 2007, the thermometer soared to 83.
Temperatures tonight will bottom out and a warming trend will commence Thursday afternoon into the weekend. A progressive flow pattern aloft will aim another disturbance toward central Louisiana this weekend. This feature, combined with more moisture and higher temperatures, will bring rain back to the forecast.
