Sun & The Moon

Planting by the Moon 

14th A most barren period. Kill plant pests and do general farm work.

15th – 16th Sow grains and forage crops. Plant flowers. Favorable for planting peas, beans, tomatoes, and other fall crops bearing aboveground.

17th – 18th Start seedbeds. Extra good for fall cabbage, lettuce, cauliflower, mustard greens, and other leafy vegetables. Good for any aboveground crop that can be planted now.

19th – 20th Barren days, neither plant nor sow.

21st – 22nd Any aboveground crops that can be planted now will do well.

23rd – 24th Good days for killing weeds, briars, and other plant pests. Poor for planting.

25th – 27th Set strawberry plants. Good days for transplanting. Good days for planting beets, carrots, radishes, salsify, turnips, peanuts, and other root crops. Also good for vine crops.

28th – 29th A barren period.

On This Day in Wx History

1998- A widespread severe weather outbreak strikes Middle Tennessee, with over six dozen reports of large hail, damaging winds, and two tornadoes. One of the tornadoes tracks for 11 miles across Pickett and Fentress Counties – the first tornado on record to occur in July in either county. Another tornado is captured on video by numerous residents as it moves through the Double Springs area just west of Cookeville. Hail up to the size of apples falls across Cookeville.

Yesterday’s National Temperature Extremes

High:  121° at Death Valley, California

Low:   35° at Sand Creek Station, Oregon 

Wednesday Weather 101

In colder air, the molecules are more tightly packed. It’s like in cold water, where molecules may become so tightly packed that we call it ice. In warmer air, the molecules are much more spaced apart. This causes cold air to be heavier than warmer air. Since gravity has a greater effect on heavier things (drop a bowling ball and a feather to prove! ha), colder air sinks toward the ground. The lighter, warmer air is able to rise. This is why cold air tends to sink, while warm air tends to rise.

Today’s Tennessee Weather 

It’s a warm and humid day across Tennessee. The warmth and humidity will lead to a few thunderstorms in the afternoon and early evening. That rain chance varies from 20% in the west to 30% in the east. Under partly to mostly sunny skies, afternoon highs will warm into the mid to upper 80s.

Tonight’s Tennessee Weather 

After a few evening showers and thundershowers, skies should be clear to partly cloudy by midnight. Warm and humid overnight lows should fall to around 70 degrees statewide.

Tomorrow’s Tennessee Weather 

Thursday is looking like a typical middle-of-July Tennessee day! Look for partly to mostly sunny skies and a chance for an afternoon or evening shower or thunderstorm. Most of us should stay dry but all of us will be humid. Afternoon high should climb into the mid to upper 80s, with many of our cities touching 90.

Drought Monitor

The drought monitor is updated each Thursday.

Weather SnapShots

A very photogenic tornado in the South Park Valley near Hartsel/Fairplay/Como, Colorado. The elevation is around 8,800 feet. Tornadoes here are very rare, but they are so beautiful when they do happen. At that altitude, the air is often drier and so there isn’t much precip to hide the tornadoes. Photo by Raymond James.
