Remnants of Harvey Soon Knock on the Door

Widespread dense fog is what we wake up to this morning!

Though visibility still struggles, we have improved in many spots. Here’s a current picture of how visibility shapes up at 8:14 am — down to a quarter of a mile for the red, half a mile for the orange and one mile for the yellow shades…VIDEO RADAR

A reminder to allow plenty of time to get to your destination and extra room between you and the car ahead of you…

An upper level system from the Great Lakes will dip far enough south to spark isolated to spotty showers and thunderstorms, especially for areas north of the I-40 corridor. Daytime highs will run closer to average in the upper 80s.

Now, back to Harvey! Over 25″ of rain and still 10-20″ to go across the southeast coast of Texas and Louisiana. Severe weather last night was just an extra added layer to the catastrophic flooding. Just horrific. My heart and prayers go out to all those impacted. The reason why there’s been so much rain in such a short period of time is due to the slow motion of the storm. Still only moving at 3 mph. You can walk faster than that!

Harvey is forecast to push further north and east, bringing unsettled weather into Middle Tennessee as soon as tomorrow (Wednesday) morning with our first rain band, lifting south to north.DAPHNE NEW HARVEY

Here’s what you need to know…WSMV CheckList

Here’s one forecast model on potential rainfall totals. Reminder: this will rely heavily on the exact path of Harvey. A further westerly track, will take away totals from east to west in our area. A further track east will bring more rain from west to east. Make sense? In any case scenario, I am confident that our western counties will get the bulk of the moisture. 1-3″ on average, with local amounts exceeding!DAPHNE ECMWF RAIN

As far as our severe weather threat, the Storm Prediction center keeps all of Middle Tennessee under a ‘Marginal Risk’ (level 1 out of 5) for any storm to reach severe criteria on Thursday.  Damaging winds and localized flooding will be the greatest threats…DAPHNE SEVERE 2 RISK REGION BOX

Harvey also takes a hit on our temperatures! Plenty of clouds and rain will keep daytime highs in the upper 70s to lower 80s…more like September! An early glimpse of fall for all who are ready to break out the pumpkin candles. 🙂WSMV_TEMP CYLINDERS TN

Unsettled weather starts on Wednesday morning and lasts through the holiday weekend. Models are a bit all over the place with the departure of Harvey remnants but I went conservative, keeping a 50% on Sunday. Hopefully it will get out a bit sooner so we can get outside and ENJOY the holiday weekend a bit sooner! Monday looks fantastic, with only an isolated afternoon shower possible.WSMV 7 Day AM

Meteorologist Dan Thomas will have the latest on Harvey and how Middle Tennessee is expected to be impacted coming up at noon today!
