Tonight: Partly cloudy skies with increasing winds to near 10 mph. Cold air advection begins to take place dropping lows to near 50 degrees.
Tomorrow: Northerly winds persist nearing 10 to 15 mph as cold air continues to usher into the area. There will be a gradual clearing of clouds as the frontal zone departs to the south. High temperatures will be cooler in the mid 60s.
Beyond: As northerly winds continue to bring cold air southward along with a surface high, Tuesday night into Wednesday morning will be the coldest with lows below or near freezing. Areas north of the I-10/I-12 corridor have the best chance of seeing sub-freezing temperatures, especially if the winds decrease enough by Wednesday morning. There is a freeze watch currently in place from 1 AM to 9 AM Wednesday morning for parishes just below and north the I-10/I-12 corridor. Clear skies, dry air, and cooler temperatures persist for the week before a gradual warming by the weekend.
Tracking the Tropics: The Atlantic is quiet for now, and development is not expected in the next five days. There is no imminent threat to the Gulf Coast.
