A deep trough to our west will begin moving eastward today. High pressure at the surface is still in place, keeping the atmosphere quite still. Sea fog has developed over the Gulf of Mexico and will continue streaming in over the course of the morning. Expect visibility to drop below 1/4 mile in many areas. Some mist and drizzle will accompany the fog. Conditions will improve by mid morning. Skies will then remain mostly cloudy for the remainder of the day. A few showers are possible, with rainfall totals less than 1/10th of an inch.
The upper trough will pull out of the Rockies, inducing the development of low pressure over the plains. This low will track northeast, dragging a cold front along with it. Southerly winds ahead of the front will keep it mild to warm tonight and through most of Saturday. A few showers are possible Saturday, with chances for rain gradually increasing toward the afternoon and evening hours.
The front will enter the region early Sunday morning. Rainfall is likely during that period. Some thunderstorms are possible, and even a few strong ones. The bigger storms are more likely for the far inland areas, with general rain and a few storms for areas south of I-10. The front will sweep through, with rainfall gradually ending during the day. Winds will shift to the north, and temperatures will fall from the mid 60s during the morning, to the mid 50s by sundown. Monday should be clear with temperatures more December like.
