We’ll start our day with mostly cloudy skies but we should see some limited clearing by afternoon. This should push the temperatures into the low 90’s easily with we get some sunshine. Storms will again develop, this time along the Tn/Al state line and south. I’ve posted the Noon hour for today, Saturday and Sunday. Of the the three days Sunday is looking the wettest.

An isolated shower is possible tonight, but most spots will stay dry.  Watch out for patchy fog after midnight, especially in the rain-soaked locales.

Friday’s rain chance is small, but we have to mention a possible shower or t’shower from morning through the early afternoon, mainly for the “southwest half” of Middle Tennessee.  Does that make sense?  Imagine a line from Clarksville to Nashville to Manchester to Chattanooga - areas southwest of that line stand the best t’shower chance.

After over an inch of rain yesterday (1.35″ - our biggest rain in 65 days at BNA) we wake up with more rain this morning. Still thinking that most of the rain/storm activity will slow drift south as the day progresses. Nashville and north will see this morning rain continue up to the noon hour at least; then the storms/rain will move across the southern counties. Some of these areas were under a Flash Flood Watch yesterday so be cautious if more heavy rain comes today- flooding of area creeks and small rivers would occur rapidly. Here is a sequence of Predictor images showing the southern drift of rain chances through the afternoon (12 to 5p) and a front on Sunday. Still a lot of time until now and Sunday afternoon but right now it looks like a cold front sweeps in just during the peak of afternoon heating: storms!

Nashville International saw 1.34″ of rain on Wednesday (through 9:00 PM).  Clarksville picked up 1.21″ of rain, mainly in the morning, although more rain is moving through Montgomery County as I type.  Not every one saw such generous rain totals, but most places managed to see around 0.5″ so no complaints there.

A few additional showers and thundershowers are possible tonight.  We’re still waiting for a front to slide in from the north.  In the meantime, Middle Tennessee stays in a humid airmass that is capable of producing additional wet weather as weak disturbances pass by aloft.

After such a wet day, I wonder about fog developing tonight…but because the sky is mostly cloudy I don’t think fog will be a widespread problem.  Still, with temperatures and dewpoints near 70 degrees later tonight (i.e., high relative humidity) some patchy fog is possible, especially in areas that saw heavy rain.

The front slides south of Tennessee tomorrow, but a shower or thundershower is still possible.  By midday and afternoon, the most likely spot for rain will be south of I-40.  A mostly cloudy sky should keep temperatures in the middle 80s.  Rain chances are much smaller north of I-40 after Thursday morning, and that should send temperatures into the upper 80s in those areas.

Nashville International Airport picked up a quick 1.2″ of rain this afternoon (on top of the 0.2″ this morning).  Many areas in Middle Tennessee have seen rain totals of at least 0.5″ so far today.

The heavy downpours are thinning out at 5:30 PM, but isolated thunderstorms will continue to move across the area the rest of this evening and tonight.

I’ll post more on Thursday’s rain chances later this evening…

Scattered thunderstorms will continue through this afternoon, mainly along and south of I-40.

At 1:45 PM it’s dry in Nashville, but I expect another round of  thundershowers to dampen many parts of Davidson County as we pass 2:00 PM.

There was a severe thunderstorm warning earlier this afternoon for northern Decatur County, on account of gusty wind and the possibility of hail (in addition to lots of lightning and heavy downpours).  A few more severe thunderstorm warnings may be issued by the National Weather Service as needed, and we’ll crawl that information on News 2 and do weather cut-ins as necessary.

We’ve got good chances of rain this afternoon. Some around this morning when I started my shift but when the front gets closer by the noon hour we should have some wide spread coverage. Not expecting severe weather but some good soakings could occur in isolated areas. Our high for the day should be around noon and then drop during the clouds/rain this afternoon and early evening.  Yesterday was the hottest day yet recorded this summer at Nashville (95) but today we will barely high 90 if that. Southern counties will still hit 90 plus as the rain will arrive last there. There is even a chance we have a wet commute tomorrow as the frontal boundary gets hung up over the state and allows for a small complex of storms to move over along the boundary. Predictor puts it south:

A front moves into Tennessee on Wednesday, bringing the opportunity for widespread showers and thundershowers.  A passing shower is possible in the morning, but rain is most likely from late morning through afternoon.

Yesterday certainly produced more in cloud cover- temperatures dropped in the afternoon thanks to the rain-cooled air around the airport. Today we don’t see the MCS dropping rapidly south like it did on Monday. We’ll likely see a few outflow boundries however and in this humid air (dewpoints in your summer-typical upper-60’s) a few storms are bound to develop. Otherwise most of us will see the clouds build in again this afternoon. Where there is more sunshine we’ll hit near the mid-90’s (like yesterday in Murfreesboro) but where the clouds build low 90’s will be the rule.

The rain chances really pick up tomorrow late as a frontal boundary draws close from the north. Below you see how the Predictor shows today’s rain and then tomorow’s front:
