Passing shower tonight, pushing warmth out tomorrow
The final weekend of the Carnival Season and the second for LSU Baseball should enjoy some more nice weather.
Today and Tonight: Morning fog will give way to sunshine and then a cold front will approach the area late. Ahead of this, temperatures will again stride for 80 degrees. As the front arrives during the evening hours, clouds will increase and a few showers may develop along the boundary. Coverage should be very low, but we can’t call it completely dry. This of course means a passing shower isn’t out of the question for the Krewe of Southdowns parade or the LSU Baseball game. Overnight, showers will end with cooler air moving in as winds shift northwesterly.
Up Next: Beneath sunny skies, weekend high temperatures will revert to more seasonable readings in the upper 60s. Sunday Morning will be chilly with lows near 40 degrees. It now looks as though showers and thunderstorms will be scattered about on Monday as highs return to the 70s. Of the two days, Mardi Gras looks less active, but still not totally dry. Another cold front will come by on Wednesday with showers and thunderstorms.
THE SCIENCE: A cold front will approach the area on Friday. Ahead of it, thermometers are expected to remain warm, registering yet another 80 degree day this winter season. Some sunshine is expected with a few more clouds developing into the afternoon hours. Some lift located ahead of and along the front may support the development of a few showers along the immediate boundary however; widespread or organized precipitation is not expected. Any rain that occurs will come after dusk. Rain coverage should not exceed 10-20 percent. By the weekend, the cold front will have pushed southeastward through the region with clearing and cooling in its wake. Skies should be cloud free through the weekend with light, northerly winds maintaining seasonable temperatures as highs make it into the upper 60s. Some wholesale changes have been made to the forecast for next week. A warm front will lift through the region on Monday. With some positive vorticity advection ongoing in the upper levels, scattered to numerous showers and thunderstorms are expected to develop. A lull may occur in the Tuesday timeframe before an eventual cold front comes by Wednesday triggering another round of showers and thunderstorms. It appears as though the front will orient parallel to the jet flow as it cross the region which will slow movement and also cause the front to weaken.
