One more day of very warm to hot conditions, with high temperatures rising into the mid/upper 90s, and heat indexes from the upper 90s to 110 degrees. Minimum afternoon relative humidity values should decrease into the upper 40s to lower 50s percent range. Winds today should be from the west 4-7 mph. Transport winds from the west around 15 mph, and mixing heights above 7000 ft ASL will produce Very Good smoke dispersion rates today. A cold front approaching from the NW will bring scattered showers and thunderstorms across Northern Alabama this afternoon into the early evening. Some of the storms could become strong to severe in intensity, with strong to damaging downburst-type wind gusts over 60 mph. Torrential downpours could also occur in the stronger storms and/or heavier showers. Shower activity should gradually end as we go into the mid and late evening. Conditions should not be as hot on Tuesday, with highs in the lower 90s. The heat could return Wednesday and Thursday with highs back into the mid 90s. Fog potential over the next few days: Patchy fog could form in and near sheltered valley locations in the late night and early morning. Additional fog could form late tonight in locations that received wetting rainfall. Potential for Red Flag Conditions: Not forecast at this time.
