A cold front will whip through the area on Wednesday Night bringing a few showers then an extended stretch of cool temperatures.

THE FORECAST:

Today and Tonight: Again, clouds and fog will be slow to break for mostly sunny afternoon skies. We’ll define the word seasonable Tuesday Afternoon with no humidity and high temperatures topping out in the mid 70s—right as it should be in the first third of November. Overnight will be quiet with a low around 60. Some fog may try to form by the morning hours.  

Looking Ahead: On Wednesday, clouds will increase ahead of an approaching cold front. Highs will make it into the low 80s and a touch of humidity will be noted as well. Current forecast model timing hones in on the overnight hours for rain associated with the front. Expect a thin line of showers to pass with little more than some gusty wind. The widespread, organized severe weather threat will remain well to the north.

In the Upper Mississippi River Valley, the threat of damaging wind and a few tornadoes serves as a reminder that the second severe weather season is just getting started. Read more, HERE.

By Thursday Afternoon, that cold front will be through the area, removing rain chances and keeping highs in the 60s. Friday and Saturday will be sunny with highs in the mid 60s and lows in the mid 40s.  

THE SCIENCE: 

Forecast Discussion: A shortwave trough cutting through the nation’s mid-section will set up a widespread severe weather on Wednesday. At the surface, a strong low pressure will move from Kansas to the Great Lakes with a cold front draped southwestward. A very strong jet stream will exist from North Louisiana into Iowa. Instability will be marginal. Given the position of the trough, low, and strongest upper level support, the severe weather threat is expected to stay well north of the Baton Rouge area. A cold front passing through on Wednesday Night should be accompanied by a band of showers and thunderstorms, some of which could have gusty wind. This will be a much more progressive system with only a brief window of rain followed by clearing skies and cooling temperatures. A surface high pressure system will move from Texas to Alabama from Friday to Sunday holding a northerly component to local winds and keeping temperatures below average through that period. While low 40s are in the low temperature forecasts for those mornings, our typical cool spots could flirt with the upper 30s.
