Mixed Bag of Weather this Week

Wow, another stunning day, just different than yesterday.  The temperatures dropped 30-40 degrees across the area from yesterday afternoon to this morning. The wind stayed high enough that there wasn’t much frost to speak of.  We are not done with the cold air, more is in the forecast later this week.  Today highs will reach near 60 degrees, a few degrees below the average for an early April day.


A strong trough of low pressure is moving into Middle Tennessee tomorrow. That will bring showers and thunderstorms by afternoon, however the severe potential is on the low side at this time.  The Storm Predication Center continues to have the mid state in a marginal risk zone, 1 on a 1-5 scale.


The ingredients are coming together. A low level jet will develop tonight and tomorrow.  Winds at the surface will also increase tomorrow, sustained at 15-25 mph with gusts to 40 mph.  There will most likely be a Wind Advisory for tomorrow.

WSMV 4 RPM wind gusts

The latest soundings are showing a favorable wind shear profile and the cold front is estimated to pass through tomorrow afternoon and evening.  But the moisture is limited, so that is one of the reasons that the threat of severe thunderstorms is low.  The greatest threat will be damaging wind. Here’s the latest timing on the Futurecast model.

After that system, the northwest flow aloft intensifies and that means several cold blast of air and a few rounds of showers late Thursday into Friday night.  Expect a light freeze in the communities in northeast Middle Tennessee.  And get this…even a chance of a winter mix on the Cumberland Plateau Friday night.

The sky will clear for the weekend, but the mornings will remain near freezing both days.  If you have already done some planting or set potted plants out, you may want to take some precautions to protect them.  With that said Saturday and Sunday afternoon will be beautiful with lots of sunshine and highs in the 50s  Saturday and the 60s Sunday.
