Tuesday AM Forecast: Few comfortable days remain before return of humidity
A weak front today brings a temporary halt to warming conditions. A sprinkle or two may fall as the front passes, but overall the most notable change will be a cloudier start to your Tuesday.
Today & Tonight: Mostly cloudy skies and mild temperatures in the 60s Tuesday morning are a sign that a front is near. As the front moves through the Capital Area this morning, a few light showers may develop, although most will remain dry. By the afternoon, skies will clear and the return of sunshine will help warm highs to the upper-70s paired with a northerly breeze. Clear skies overnight will allow temperatures to drop near 49° in Baton Rouge early Wednesday. A light jacket may be needed.
Up Next: Wednesday will be very comfortable with low humidity, light winds, full sunshine, and an afternoon high near 80 degrees. Thursday will keep the pleasant conditions going, with mostly sunny skies and highs in the mid-80s.
Easter Weekend: On Friday, a southerly breeze will ramp-up and assist in the return of gulf moisture (a.k.a. humidity) to the area. The return of a muggy feel will also be accompanied by warming temperatures and increasing clouds. Friday afternoon will see a mix of sun and clouds with highs in the upper-80s. Saturday will also be warm with a few more clouds around. On Easter Sunday, a few spotty showers (20% coverage) may squeeze out of mostly cloudy skies, although no washout is expected. Highs on Easter will reside in the mid-80s after a mild morning with lows in the upper-60s. Into the next workweek, there is a decent signal that daily rain chances may make a return.
