Temperatures will tumble later this evening after a cold front pushes through this afternoon. Some brief cloud cover will move through just behind the front, then skies will clear again overnight.
The forecast brings the front through Acadiana around midday. Winds will then pick up from the north and could be quite gusty later this afternoon. After a midday high in the upper 60s, temperatures will likely drop back into the upper 50s again by sunset. Winds will remain in the 15-20mph range into the evening.
Overnight, the winds will lighten up somewhat. With clear skies and very low dew points, temperatures will drop to near 30 in Alexandria, 31-32 in areas north of US 190, and 33-34 along the I-10 corridor. South of I-10 should see temps between 34-38 with lows near 40 right along the coast. Winds will remain in the 10mph range, so wind chill values early Wednesday should be in the upper 20s.
This won't be a pipe bursting freeze, just a light freeze that will kill tender, tropical vegetation. The best thing to do is bring in or cover the more suseptable plants. The higher winds won't prevent a freeze, but frost shouldn't be a problem. Pets will need a warm spot too.
Temperatures will only recover into the upper 50s on Wednesday and breezes will make it feel more like the 40s most of the day. Wednesday night into Thursday morning will be equally cold, but since winds are expected to be very light, frost could be an issue. Keep in mind that frost might form in areas where the temperature hovers just above the freezing mark. Frost could be over the northern half of Acadiana early Wednesday and patchy rural areas south of I-10.
