It's a quiet start on FIRST ALERT Doppler radar, with temperatures in the upper 60°s to lower 70°s. However, rain coverage will increase throughout the day. There's a sun/cloud mix Friday morning, with clouds and a 70% chance of rain and thunderstorms in the afternoon. It will be "somewhat" cooler, with a high of 87°.
Overnight, it will be mostly cloudy, with scattered rain and a low of 70°. Saturday, there's a 70% to 80% coverage of showers/storms, with a high in the mid/upper 80°s and for your Sunday, depending on position Invest 90L in the Gulf of Mexico, rain is still probable, with temperatures in the mid 80°s.
Additional development of Invest 90L, ultimately becoming Alberto, now seems to be a near-certainty. In addition, updated forecast models are showing a general consensus landfall forecast somewhere between southeast Louisiana and the Alabama/Florida line as a tropical or sub-tropical storm. The general thinking is that it does not reach the Central Gulf Coast before Monday.
