Moisture associated with the remnants of Laura are set to bring soaking rain starting the weekend. A cold front eventually clears things out by Sunday, which will bring a markedly drier air mass into the region. Temperatures during this period will be generally cooler than at most points this week, in the low-80s. Next week, we could see a return to hotter weather towards mid-week.
Rest of today – increasing clouds with high temperatures in the upper-80s. Chances for rain and thunderstorms later in the day along a warm front that’s forecast to lift through during the day. Overnight lows in the low-70s with rain chances continuing.
Saturday – Laura, which wrought serious devastation over the Gulf Coast, will make itself felt on Saturday, contributing tropical moisture to rain that will impact the area. This moisture will contribute to very high precipitable water content > 2″, which could lead to localized flooding. Mostly cloudy with rain possible throughout the day. Stronger storms are possible in the afternoon. High temperatures in the low-80s. Overnight lows in the upper-60s with rain chances diminishing as a cold front sweeps through.
GFS model precipitable water content valid 8AM Saturday. Very moist values of > 2.00″ are possible. 
Weather Prediction Center’s analysis of possible rainfall totals Saturday. Parts of the region could see easily see 0.75-1.00″.
Sunday – by the morning, the trailing cold front associated with the primary low bringing this rain should’ve already pushed through. This will lead to a much drier, cooler day, with high temperatures peaking around 80ºF and plenty of sun. Winds may be gusty at times from the northwest. Overnight lows in the low-60s due to good radiational cooling with clear skies and winds calming.
Monday – even cooler than Sunday with high temperatures in the upper-70s, and sunny skies. Overnight lows in the mid-60s.
