Flooding possible this week

Posted: Updated:
CHATTANOOGA, TN (WRCB) -

Good Tuesday.  A Flood Watch has already been issued for north Georgia for Wednesday morning through Friday morning.  I suspect one will be issued for the entire area at some point as we are expecting 2"-4" of rain to fall during that time period.  That would be on top of the heavy rains many of us have already seen this week, saturating the ground, and priming it for flooding later this week.

For today, we can expect another round of spotty showers and thunderstorms, some producing heavy rain.  They will taper off late tonight. Highs today will be in the mid 80s.

Wednesday, a trough of low pressure to our east will back into the Tennessee Valley, creating more widespread showers and storms Wednesday afternoon.  That trough will sit over the area Wednesday through at least Friday, and could even be with us on Saturday as well.

As long as that trough is over us, it will continue to transport abundant moisture into the area from the Gulf of Mexico which will translate into heavy rain.

The ground is already saturated, so the 2"-4" we are expected will almost certainly produce widespread flooding issues by the weeks' end. 

The 4th of July looks wet for the fireworks, so the backup plan needs to be ready to go for Thursday evening.
