HUNTSVILLE, Ala. – You won’t need a jacket this week, but you might need to get your air conditioning going again. A ridge of high pressure will center itself over Alabama and continue the trend of hot, dry weather that we’ve been stuck in since the summer. High pressure causes sinking air and when air sinks it’s forced to compress and heat up. So, when high pressure settles right overhead, it causes temperatures to soar.
So once again, we’ll be talking about unseasonably warm temperatures in the Valley. Average highs in mid October range from 73ºF-76ºF, but our high temperatures will be reaching into the upper 80s and even touching close to 90 this week. The record high temperatures Monday-Wednesday of this week range from 88ºF-90ºF, but it’s likely that we could set new records this week.
This record breaking heat will be followed by a cold front Thursday though, which could bring some big changes. Temperatures by next weekend could even fall below average, with highs back down in the upper 60s!
