Good evening Tennessee Valley and a very happy Thursday! Rain was scattered through the first half of the day, but then the heavier bands moved in as we got into the heart of the afternoon, and now it’s here to stay through the immediate future. This heavy rain is ahead of a cold front that will eventually push through the Tennessee Valley tomorrow morning. Behind that cold front is much drier air that will allow us to see more sunshine on Friday and even most of the day Saturday.
The big concern continues to be the combination of the wind and the heavy rain that only continues to saturate the ground. The highest reported wind gust so far comes from HSV who reported a wind gust of 45mph. Given the possibility for these stronger winds to continue into the early part of the overnight, the NWS has chosen to continue the wind advisory through midnight.
Rain totals will be beyond impressive by the lunch hour Friday everyone east of I-65 may have anywhere between 2” and 4” with folks west of I-65 seeing slightly less. With the passage of the cold front tomorrow morning the rain will gradually come to an end west to east, and the clouds will also begin to fizzle on out of here as well.
Temperatures will be seasonable Friday and Saturday with highs hanging out in the low 50s. I also think we could see a gradual decrease in temperatures through the afternoon. I wouldn’t be the least bit surprised if the forecast high of 65 occurs decently early in the day.
The dry conditions through Friday afternoon and the day Saturday will not last very long. There is another system developing over the SW United States that will eventually push east Sunday and then into NYE. This developing system will increase southerly flow especially heading into NYE. This will once again bring the chance for heavy rain across the Tennessee Valley. I think it is safe to assume any outdoor NYE parties should probably be moved inside. Again the big concerns here will be high rain totals with the potential for another 2+” by noon on January 1st.
The forcing mechanism here will be a cold front that will come through on Tuesday. Behind that cold front are winds from the north that will prevent temperatures from making it much higher than the low 40s both Wednesday and Thursday of next week.
