As I write this Andrew is on YouTube Live covering two Severe Thunderstorm Warnings. Will is on the tweeter, tweeting about them. These are hail storms. Lightning frequent and intense. Severe straight line winds are possible but there is no reason for early morning tornado concerns.
Nashville. Williamson County. Saturday morning. A weary community awakes.
A warm front arrives. Behind it, a waterlogged atmosphere.
HRRR Model
7 AM, rain begins. Will Co first. First rain drops south of I-40. Soon the tattered rain curtain covers both counties.
Check out today’s sunrise over the hills surrounding Grassland in Williamson county.
After last night’s severe weather, we dry out for most of today followed by decreasing clouds throughout the morning. We’ll be topping out near the upper 60s for our high temperature and the lower 50s for our low overnight tonight.
If you only take one thing away from this blog please remember this: Stay connected all day today. We will be updating you on Twitter (@NashSevereWx) all day. We will go on YouTube Live if a warning is issued in either of our two counties. Do not read this blog and tune out. Things will change as this situation develops.
Our current thinking is that storms will come in two rounds. HRRR below shows round 1. We’ll see rain begin to move into the area around 8 am. Although this will not be the severe weather event, we will begin to see high rain totals. Do not mistake this for the main event.
Rain is approaching from the west this morning. The HRRR model (below) thinks it’ll break up before it gets to us.
As we publish this, the rain line is two counties away, moving closer, and has not (yet) broken up. We’ll follow this through the morning on Twitter.
Rain is pretty likely Tuesday. Notice how it scatters and breaks up as it gets into Middle Tennessee on the Euro model (but we still get rained on):
The HRRR model doesn’t think it’ll break up. It thinks a heavier band of rain will cross through after lunch.
All these upper 60s-low 70s have us feeling:
An upper level low will pass through the midwest Tuesday. This should spark some off and on rain Tuesday, maybe into Wednesday.
But the data isn’t giving any clues to timing. It’s possible all the rain misses your backyard.
March 20 marks the first day of spring in the Northern Hemisphere! Satellites caught something pretty cool this morning:
Editor’s Note:
Clouds will continue to move out this afternoon, giving way to beautiful skies.
Chilly (maybe sprinkly at times) today until clouds clear. Image below from 9:21 AM. Clearing line may not arrive until late this afternoon. Therefore only 54°. Cold north wind.
Close to freezing around dawn Saturday and Sunday mornings. Then we warm up.
