Frost Next Saturday??

1:25 PM Saturday, October 5, 2019

There are more concerted indications in the weather pattern that Fall is going to take over.

The focus is on next weekend when there is agreement among our long-range
global models that will show the flow aloft being dominated by a low over the western Great Lakes. 

That Saturday morning a chilly surface ridge is expected to settle into our area as noted by the forecast map below.


Here is one model's forecast low temperatures Saturday morning October 12th. These temperatures could open the door for scattered frost in some areas.  It is still several days away and the forecast will change.  

The below-normal temperatures are expected to continue after that from October 12 through October 17. During this period the average highs are around 73º and average lows are around 48º. Below are the projections from the 3 main long-term models.



This certainly suggests that frost could be possible during that period.  By the way, the average date for the first frost in Jackson, TN is October 17th.
