Next Several Days
A low pressure center at 500 mb (that’s at 18,000 feet) will wander south from the Great Lakes, then spin around through the 4th of July. See the below (patriotic) loop from June 29 through July 7. The low pressure is red. This will “unsettle” our weather through the 4th.
Our NWS says:
THIS DOESNT MEAN IT IS GOING
TO RAIN EVERY MINUTE OF EVERY
HOUR BUT THERE WILL BE AN ON-
GOING CHANCE FOR SHOWERS AND
A FEW THUNDERSTORMS ON A
DAILY BASIS.
They continue:
EVEN AFTER UPPER LOW LIFTS
NORTHWARD INTO CANADA
AROUND JULY 4TH WE HAVE
SUCH A GOOD MOISTURE FEED
FROM THE GULF OF MEXICO
INTO THE TENNESSEE VALLEY
THANKS TO A RATHER STRONG
BERMUDA HIGH KEEPING THE
CHANCE OF SHOWERS AND
THUNDERSTORMS.
Here’s the GFS (weather model) opinion on the precipitation for the same time frame (June 29 to July 7).
Sunday – High 80, Chance of Showers or a Thunderstorm
Monday – High 82, Chance of Showers or a Thunderstorm
Fireworks Forecast
It’s way too far away to know, but there is a chance of rain. The GFS pumps moisture in, but the European model sends it into east Tennessee.
Enjoy this weekend!
