First things first. SHARNADO!
Those of you following on Twitter know I’ve been way too excited for “Sharknado,” airing tonight at 8 p.m. on Syfy. I love terrible tornado movies (which means I love all tornado movies).
Sharknado! And Your (Mostly Perfect) Weekend Forecast
Storms Possible Tonight; Transition Thursday to a Wonderful Friday
Today – Thunderstorms Possible – High 94
The heat index made it over 100 today.
Our NWS gives us a 60% chance for thunderstorms tonight and into the overnight. We are not exactly sure if we will get the full brunt of these storms, get clipped by them, or have them miss us completely.
Storms Likely Tomorrow
Today – Pop-Up Thunderstorms Possible – High 93
There could be a few random blips of rain in the area today. Most of the action is well to the east, near Cookeville. We may see a few showers try to sneak in from the northwest later on, but the HRRR isn’t a believer on them getting here.
Typical Pop-Up July Showers; Thunderstorms Wednesday
Tonight – High 88
Rain is starting to bubble up, mostly notably north of and in downtown. Classic summertime weather. This should diminish after dark. Patchy fog will be developing late tonight.
Tuesday – Pop-Up Thunderstorms Possible – High 91
Back to Normal: Humid, Chance of Afternoon Thunderstorms
Today – Drying Out Afternoon Maybe a Few Showers – High 87
Today’s rain appeared in east Tennessee (near Chattanooga). So far, nothing for us.
South winds will deliver humid air over the next few days. With that comes a slight chance for some isolated rain showers (but don’t bet on it today).
Rain Finally Ending; High Humidity Returning
Today – FLASH FLOOD WATCH – High 74
Clouds are exiting Middle Tennessee, moving north-northeast. The relentless rain shield has moved out.
The HRRR model gives us a few more stray showers tonight. Here it is from Saturday 4 PM to Sunday 1 AM:
More Rain on the Way: 3″ Expected Through Sunday Night
Strong high pressure over Bermuda is pulling moisture in. A trough has set up to our west. This is working to squeeze out the moisture, like wringing out a wet t-shirt.

Wet Fourth Continues Through The Weekend
Friday – FLASH FLOOD WATCH Until 7 p.m. Showers & Thunderstorms, High 82
(7 am 68 . 10 am 77 . 1 pm 81 . 4 pm 82 . 7 pm 80 . 10 pm 74).
Most weather models predict the rain end around 6 a.m. to 8 a.m, if not before then. We may be dry through lunch, and maybe even as late as mid-afternoon. Then, rain chances increase the later in the day we get. Another batch of rain is expected Friday night.

Fourthcast: Flash Flood Watch
Overview
You won’t find any jokes in this fourthcast, because it sucks.
An unusually wet weather pattern is arriving, and it won’t change for the next several days. This will be like a tropical system, full of moisture and thunderstorm chances. Strong to severe thunderstorms cannot be ruled out at any time over the next several days.
But the main story will be rain. A lot of rain.
Tonight
Rain will be close by. Weather models keep the rain in East Tennessee, but extend it as far west as I-65. This may be our last dry night for a while.
Fourthcast
