Although cold Saturday morning most locations on both sides of the lake managed to stay just above the freezing mark. The windy conditions and cloud cover kept temps from reaching the thresh hold, but that will not be the case tonight. This evenings Carnival celebrations will be nippy with temperatures during the evening hours dropping rapidly and putting most spots in the low 40s and even upper 30s before parading wraps up.
Perfectly clear skies and the dying wind will make for an even colder night Saturday into Sunday. A few spots to the extreme north will flirt with a hard freeze where temperatures get down into the mid twenties for several hours. That's pipe bursting cold and while the National Weather Service dropped it's hard freeze watch, conditions are such that it would only take a minor change for it to go back in that direction. I would continue to use full freeze precautions to protect people, pets, plants and pipes in the northern parts of Tangipahoa, Washington and St. Tammany Parish and the Mississippi Counties.
Sunday expect a turn around in temperatures. It will still be chilly with highs in the low 50s, but a weak warm front will approach causing late temperatures to rebound early and keeping most locations from getting down to freezing on Monday morning.
Monday afternoon a fast warm up brings highs into the 60s. More clouds and moisture push in from the Gulf to fuel our next chance for rain. That comes on Tuesday as another cold front sweeps across the area allowing temperatures to fall back into the 40s by Wednesday morning. Wednesday could be a cold and wet day with the sunshine finally returning next Thursday. Friday kicks off another round of Carnival weekend with seasonable to slightly cooler than normal readings in the 50s during the day, upper 40s for evening parades and lows in the 30s to near 40 overnight into Saturday.
