Cold front arrives later today
For a second straight day, the record high temperature was tied as Wednesday topped out at 90 degrees. While there were some spotty showers, the Baton Rouge dry stretches was officially extended to 17 days with no precipitation at Metro Airport. After a slight shot at ending that streak today, the area will most definitely see the streak of above average temperatures conclude today.
Today and Tonight: After partly sunny skies early and highs in the mid 80s, a cold front will arrive Late Thursday, bringing the best opportunity for showers and thunderstorms in quite some time. Late in the day, a broken line of showers will cross the area from northwest to southeast as the front moves through. North winds of about 10mph will then take over, sending Friday Morning lows down to near 60 degrees. Any rain that develops will be over with by dawn.
Up Next: Highs won’t exceed the mid 70s Friday or Saturday Afternoon and weekend morning lows will flirt with the upper 40s. Clear skies are expected throughout. For high school football games, be sure to bring a jacket as thermometers will fall back into the 60s through the game. For those planning on spending Saturday at LSU or Southern University, take layers. Morning tailgates and the late afternoon/evening gameplay will be chilly in the 60s and 50s, while the midday hours could be briefly comfortable with sunshine running temps into the mid 70s. Hey, sounds like football weather! The nice conditions will carry through Sunday.
The Tropics: An unorganized area of showers and thunderstorms north of the Turks and Caicos will find upper levels slowly becoming more favorable for development over the next few days. A tropical or sub-tropical storm may form—which would be named Otto—but regardless of development, the same cold front bringing relief to the local area will push this system out to sea.
Forecast Discussion: As a cold front moves into Louisiana on Thursday, shallow moisture and associated frontal lift should provide the best chance for Southeast Louisiana and Southwest Mississippi in more than two weeks. Even so, many locations—especially those south of I-10—may stay dry. Prior to the front, highs will make it into the upper 80s. As the front crosses from northwest to southeast through Thursday Evening, winds will begin to turn northerly and the onset of drier and cooler air will begin. By Friday Morning temperatures will fall back into the lower 60s and potentially lower if clouds scurry through before dawn. Continued north winds on Friday will leave highs in the mid 70s despite ample sunshine. The remainder of the weekend will feature the coolest mornings since Early May with possibly some upper 40s and seasonable sunny afternoons with highs in the mid to upper 70s. A surface high pressure area will end up east of the region by early next week allowing east-southeast winds to moderate the air mass back to slightly above average temperatures. Another shot at rain isn’t foreseen through next Wednesday.
