High temps in the upper 80s with clouds hanging overhead all day. TD Gordon keeping our dewpoints high; humidity is oppressive.
TD Gordon has moved into western Mississippi – seen here as the small area of blue and white convection over the MS delta. Today it’ll move further west into Arkansas, pushing more moisture into Davidson and Williamson counties.
Tropical Storm Gordon made landfall last night just west of the Alabama/Mississippi state line. This morning, the center was located near Jackson, Mississippi and is working its way toward Louisiana and Arkansas.
Hot and muggy. High temps in the low 90s with a heat index in the upper 90s.
The HRRR model thinks we could see a few scattered storms this afternoon/evening. This model thought the same thing yesterday and nothing happened. But, it could be right today. Any storms that go up will be traveling quickly from south to north.
Today is turning out “Sweaty not Wetty.” High pressure defeated any effort to sprout storms. A few defiant cells may sprout over the next few hours. We’ll tweet them @NashSevereWx (and here) if they do.
It’s hot today but not sure it’s a “scorcher.”
We wrote “Sweaty Not Wetty” last night only to wake up this morning to HRRR model runs popping off isolated late afternoon/early evening downpours and thunderstorms:
The Storm Prediction Center does not think we will see Labor Day thunderstorms:
The Weather Prediction Center forecasts for us no Labor Day rain:
NWS-Nashville agrees, figuring only a 10% probability of precipitation (black arrow) and betting no rain will actually hit the pavement (red arrow):
It’s possible an isolated shower or storm will pop up this afternoon. The HRRR model thinks so:
As usual for summer, shower/storm locations are unknown. Buy a lottery ticket and hope for the best.
Happy First Day of September!
Meteorological Fall
If you follow the meteorology community on social media, you may see the term “Meteorological Fall” thrown around today. This refers to the beginning of what are considered the “fall months” of September, October, November. Not be confused with the fall season which begins on September 22! Fall temps are still out of reach.
Ok, everyone on 3… 1, 2, 3, Summer! Time! Pattern! Today is another day in the hot soupy mess. Temperatures will be approaching 90º for a high today with dew points in the 70º range. It will be hot, even in the shade today.
Clouds will be pretty widespread today, keeping high temps in the upper 80s. Dewpoints are oppressive, in the low 70s, a normal for late-August.
Morning showers over Nashville left our atmosphere with plenty of moisture and instability that could kick off afternoon showers and storms. Any storms that go up aren’t expected to reach severe levels.
