The first freeze of the season appears to be upon us. Cold dry air is settling in behind a cold front that moved through late Friday night into Saturday morning. Clear skies with plenty of sunshine allowed afternoon temperatures Saturday to rebound into the mid 60's. Saturday night, lows will reach the middle 30's north of the lake and 40's away from the water with temperatures closer to 50 near the lake on the south shore and coast. Sunday morning, temperatures should stay above the freezing mark.
During the day Sunday, expect more sunshine with a chilly breeze. Highs will be in the upper 50's to middle 60's. The real headlines come after nightfall with the coldest night of the season so far expected by Monday morning. Lows will dip close to freezing on the North Shore and along the Mississippi Gulf Coast. With our first chance at freezing conditions since last spring the National Weather Service issued a freeze watch for Washington, Tangipahoa and St. Tammany Parishes. The lake will keep the city in the middle 40's. The River and Bayou Parishes will likely see mid to upper 30's on Monday morning. Pipes are not a concern, but pets and plants should be cared for in the affected parishes.
The cold doesn't last long. Temperatures warm a bit as we head into the middle of next week. We may see a few showers Wednesday ahead of a weaker cool front that will clear us out again for Thanksgiving. This will keep temperatures moderate, but it won't be nearly as cool. We should see plenty of sunshine with seasonable temperatures in the low 70's for highs.
