September 13: Increasing Heat and Humidity, Daily Links

WEATHER

The past couple of days were very pleasant, with warm afternoons and cool nights…and best of all, low humidity!  This morning started off pleasant for most of us, but the heat and humidity will be increasing today — and the summertime weather looks like it will stick around the rest of the week.

Today’s highs will top out around or just above 90 degrees:

Dew points were in the 50s the past couple of days, but they’ll be back in the not-so-comfortable mid 60s by this afternoon:

As the humidity increases, we’ll see a chance of pop-up storms this afternoon, mainly south of I-40 and along the Cumberland Plateau.  The HRRR model’s radar simulation looks impressive in southeastern Middle Tennessee, but even there I think it’s just a 30% chance this afternoon:

More of the same tomorrow through the rest of the work week.  The changes arrive this weekend, with better storm chances and slightly cooler temperatures:

Don’t cancel any outdoor plans this weekend — there’s still some uncertainty regarding the evolution of the overall weather pattern, and even a 50% rain chance leaves us with plenty of dry hours as well.  It’s still too early to focus on the exact timing and placement of those rain chances…hopefully those details will come into better focus in the next couple of days.

    Yet another streak
    The last few months we’ve had a number of record and near-record streaks related to heat, and here’s another one most should find pleasant. We’re currently enjoying the longest stretch of fair weather since the summer of 2012. It’s been 17 days of partly to mostly sunny days and today might be the 18th, eclipsing the streak of 12 days from last October. There were 19 such days back in 2012, running from 6-13 thru 7-01. That was the last year when Nashville had a lot of sunny days. This spell of fine weather is a welcome break from rather cloudy and hazy conditions that dominated most of July and August.
