Halloween is here, and it's going to be the coldest night so far this season. This Canadian air is actually a little late in getting here, according to Louisiana Climatologist Barry Keim.
"I'm surprised it took this long to finally get this firs real surge of Canadian air down here," said Keim. "We've had a couple of surges before this one, but they didn't have the bite this one has to it. In fact, some of those earlier surges were actually air coming off the Pacific Ocean, the north Pacific."
Those fronts were milder by comparisons, dropping overnight lows only to the 50s and 60s, with daytime highs in the 70s. Temperatures have fallen into the 50s for today and tomorrow, with overnight lows in the mid-30s north of the lake, and mid-40s on the south shore.
Meanwhile, as we close out October, Keim says we can pretty much also close the book on hurricane season for Louisiana.
"As far as hurricane season goes, by the time we get to the end of October, if we make it through Halloween, the season is over as far as I'm concerned," Keim said. "We have over 150 years of records, and we've never had a landfall in Louisiana in the month of November."
Hurricane season ends November 30, although December named storms have happened as recently as 2007, when Tropical Storm Olga (not to be confused with last weekend's storm that caused power problems lasting into this week for some Louisianans) formed north of the Leeward Islands and hit the Dominican Republic.
