Tracking Thursday afternoon/evening storms. Some could be strong.

Threat Tracker.png

8am update

Showers continue in central TN back in to AL/MS. They continue to drift NE and will take a while before they arrive locally. We have a "Marginal Risk" for storms locally, which is the lowest of the categories. Meaning only isolated storms possible. However some could be strong and disruptive this evening.


Timing: (Note timing in graphics)

  • Plateau by 3/4pm.
  • Chattanooga/NW GA/West of I-75 around 5-7pm
  • East of I-75, Cleveland, Dalton, to Murphy 7-10pm.

What to Expect:

  • A line of showers and embedded storms.
  • Some storms could contain gusty to strong winds along the leading edge. Wind gust could exceed 50mph in isolated stronger storms.
  • Can't rule out some small hail.
  • Only a small chance of a brief tornado, but that threat is greater in Central AL.

How much rain?

  • Most will see around a half inch or so. Flash flooding not a major issue, however heavier rain will no doubt cause issues on the roads.

BOTTOM LINE:

Our threat is fairly low and most will see brief heavy rain, rumbles, gusty winds. We just can't let our guards down with any storms this time of year. Rain will end by later tonight. Cloudy, to partly cloudy and cooler Good Friday.

As always, you can follow along on our facebook and twitter pages.

SOME SHOWERS & STORMS THURSDAY

Overnight shower/t-shower chances Wednesday Night continues through Thursday Morning. Again, the slow moving cold front will determine how long the rain continues and if the rainfall amounts get too heavy. At this time, it appears that the heavier rain could stay to our west over Middle Tennessee and into North Central Alabama. The rain coverage of Thursday appears to be off and on. So, between showers & t-showers expect a cloudy and warm pattern with temperatures again in the 70s. As the front moves closer to us during the afternoon and evening, then coverage of showers and storms increases again and continues off and on overnight Thursday Night.

The overall severe storm threat remains low at this time, but we will continue to monitor this. The Storm Prediction Center has most of our viewing area in the "Marginal Risk" category. That is the lowest threat category, but not zero. This means that a few storms could have lightning/thunder and gusty wind, but the threat of widespread severe storms is low. Rainfall amounts could be tricky, especially if the front stalls. For now, rainfall projections could be in the 0.50" to 1.00" range. This is based on the averages of forecast models. If that amount holds, then any flooding threat could remain low. Again. we'll be watching this as the front draws closer.

DRIER START TO THE EASTER WEEKEND

Any remaining showers should end Friday Morning, then drier and slightly cooler by Friday Afternoon with highs in the 60s. A bit chilly Friday Night as temperatures dip back into the low/mid 40s. Saturday looks very nice with a chilly morning, then sunny and mild through the afternoon with mid 60s. Sunrise Easter Sunday is at 7:28amET and temperatures should be in the 40s under a cloudy sky. There is also the chance for some light rain on Easter with afternoon temperatures in the low/mid 60s.

As always, you can depend on the StormTrack 9 Team to keep you updated as the holiday weekend approaches!
