Thursday PM Forecast: weak front brings subtle change ahead of weekend
A beautiful stretch of spring weather continues across the Baton Rouge area, with sunshine dominating the forecast and just a slim chance of rain in sight. Adding to the pleasant conditions, there is no noticeable humidity in sight.
Tonight & Tomorrow: Overnight, a weak front will slide through the region, but don't expect much more than a few high clouds and maybe a slight breeze. Temperatures will drop into the upper 50s. By Friday, cooler and drier air settles in behind the front, bringing dew points down into the 40s and highs in the mid-to-upper 70s — perfect weather for getting outdoors.
Weekend & Beyond: The weekend continues this cool and dry trend, with sunny skies, highs in the mid-70s, and crisp morning lows in the upper 40s — about 10 degrees below normal for April. Saturday and Sunday look absolutely gorgeous.
Heading into next week, high pressure sticks around and gradually warms us up. Monday and Tuesday bring a return to low 80s for highs, with slightly milder mornings in the upper 50s and low 60s. A weak front is expected to pass through Tuesday night, but with limited moisture, the best we can expect is a brief spotty shower — only about a 10% chance, and most will stay dry. Wednesday looks sunny again, with highs in the low 80s and morning lows dipping back into the 50s. All in all, it’s a calm, comfortable, and mostly dry spring forecast — ideal for enjoying some fresh air without sweating it out or getting rained on.
