April 24: Drying Out…Finally!

WEATHER

Some HEAVY rain fell over the weekend, causing widespread flooding problems.  Just a sampling of the rainfall observations gives you an idea of the amounts:

Nashville went into the weekend about 3 inches below-average for year-to-date rainfall…now we’re about an inch above average.

The weekend’s rain has now dissipated, leaving us with just a few light showers in eastern Middle Tennessee today.  The HRRR model’s radar simulation shows the meager rain chance east of I-65:

Despite the drier weather, mostly cloudy skies will prevail today, with high temperatures only reaching the mid to upper 60s:

Some dense fog will develop late tonight into early Tuesday morning — once that burns off, we’ll see a lot more sunshine on Tuesday, with highs near 80°:

Partly cloudy and warm during the day Wednesday with highs in the mid 80s, then the next chance of showers and thunderstorms moves in late Wednesday night and Thursday morning.  An early look ahead with the RPM model shows the storms weakening quite a bit as they move in from the west:

More showers and storms possible on Friday, but that chance is still up in the air at this point.  The American GFS model keeps us mostly dry, while the Canadian and European models show widespread showers and storms.  I don’t trust the GFS model as far as I could throw the supercomputer that runs it, so I’ve tipped the forecast in a wet direction:

We should be mostly dry on Saturday, which is good news for the Country Music Marathon (yes, it’s technically the Rock ‘N’ Roll Nashville Marathon, but come on).  The bad news is that it’s going to be steamy: temperatures will start in the 60s and warm up quickly, reaching the mid 80s by Saturday afternoon:

Dew points will be in the low 60s, which means the mugginess will be a significant factor for folks trying to finish the half-marathon or the full marathon route.  Another round of potentially-severe storms will head our way late Sunday — that’s a LONG way off in the forecast right now, so don’t adjust any plans yet.  We’ll keep you updated as the weekend gets closer.

Doing double-duty on weather and traffic this morning, so no time for the nerd-links.  I’m off tomorrow, but the nerdiness will be back in full force on Wednesday.
