Cold Front/ Frosty Air on the Way

Colder weather may be on tap as we move into October. Growers may want to move to protect tender or cold sensitive plants, from light frosts, before next weekend.
Retailers need to move house plants and tropical foliage into heated greenhouse space. Autumn is definitely here and we can expect to see frost on the pumpkins real soon.

This in from the NOAA Weather service.....

There is remarkable agreement among medium range models and ensembles alike indicating a sharp turn to a strongly positive PNA pattern...which supports a deep trough over the eastern US. Look at the plunge in the 1000-850 mb thicknesses late Thursday once the front swings through. If these verify...we could see min temperatures Friday morning of next week in the upper 30s to lower 40s. If this pattern holds, we will really need to undercut MOS guidance during this period. Notice this pattern is projected to hold through nearly the first half of October. It should be interesting to see if this does indeed hold up and if we will need to break out those sweaters.
