Today expect rain this afternoon with a small thunderstorm chance, falling temps tonight, maybe a few snowflakes overnight with little or no accumulation, and a lot of wind. This is “Marchuary” (a term used by Tom Johnstone, who is the Warning Coordination Meteorologist at the NWS in Nashville) at it’s finest.
The NWS explains the Wind Advisory below. NWS’s system is set up in all caps. They’re not trying to yell at you. Science!
AS BOTH A SURFACE AND UPPER LEVEL LOW PRESSURE SYSTEM MOVE ACROSS MIDDLE TENNESSEE THIS AFTERNOON AND TONIGHT…A TIGHT SURFACE PRESSURE GRADIENT WILL DEVELOP WITH SUSTAINED WINDS OF 20 TO 30 MPH AND GUSTS TO 40 MPH POSSIBLE. WINDS WILL BEGIN TO DIMINISH AFTER SUNRISE ON MONDAY.
…WIND ADVISORY IN EFFECT FROM 1 PM THIS AFTERNOON TO 7 AM CDT
MONDAY…* WINDS…SUSTAINED 20 TO 30 MPH WITH GUSTS TO 40 MPH.
* IMPACTS…TREE LIMBS MAY BE BLOWN DOWN AND DRIVING HIGH PROFILE VEHICLES WILL BE MORE DIFFICULT. LOOSE OBJECTS MAY BE TOSSED AROUND.
A WIND ADVISORY MEANS THAT WINDS OF 25 TO 39 MPH AND/OR GUSTS OF 35 TO 57 MPH ARE EXPECTED. WINDS THIS STRONG CAN MAKE DRIVING DIFFICULT … ESPECIALLY FOR HIGH PROFILE VEHICLES. USE EXTRA CAUTION.
Here’s NOAA’s take on the percentage chance of Snow greater than 1″ from 7am Monday thorugh 7am Tuesday. We are somewhere in the 5% to 10% chance.
As in all things weather, embrace the uncertainty.
