Forecast Discussion
Wednesday: A couple of shortwaves will move through the area. However, without a return flow ahead of the shortwaves only limited moisture will be in place. The day will be mostly cloudy with a slight chance of some light showers if any of the limited moisture can be squeezed out of the atmosphere. Winds will be from the north around 5 mph. PM2.5 will continue a slow rise and is expected to be in the upper green range. ML

Thursday: A second upper-level disturbance in as many days within an elongated trough. The disturbance will move eastward in the northern Gulf to bring a slight chance of light showers in the area through the morning hours. Clouds will begin to somewhat break later in the day as the disturbance moves east of the area. Winds will be from the N and NW around 5-10 mph. PM2.5 will stay relatively steady along the green/yellow borderline and thinking is that it will be in the upper green range for the day overall. ML
