October 18: Heat Wave Continues, Daily Links

WEATHER

The October heat wave rolls on — we have near-record high temperatures in the forecast both today and tomorrow, with highs in the upper 80s.  Today’s record of 87° in Nashville is likely to be broken:
tuesday-highs
And we’ll at least approach tomorrow’s record of 89°:
wednesday-highs

We’re far from alone in this weather pattern…today’s high temperatures will be near record territory across the region:
tuesday-region

A good chance of showers and thunderstorms moves in Thursday, which will bring an end of the warm spell.  The timing of the storms is still up in the air, but the forecast models are indicating some morning shower activity:
rpm-6a-thu rpm-9a-thu
Which then gives way to some stronger storms from midday, through the afternoon and into early evening:
rpm-12p-thu rpm-3p-thu rpm-6p-thu rpm-9p-thu
The atmospheric setup won’t be all that favorable for severe storms, but any time there’s such a sharp temperature change we can expect some fireworks.  The Storm Prediction Center has outlined a “Marginal Risk” of severe thunderstorms producing damaging thunderstorm winds:

I’m not too worried about it at this point, but we’ll dive into some details tomorrow as the overall situation comes into better focus.

Temperatures will drop significantly behind that storm system, with highs Friday and Saturday only in the 60s, and overnight lows dropping to the 40s!
