Smoky Mtn Observations

A heat wave is expected into late next week with highs rising into the low to mid 90s and heat index values reaching or exceeding 100°. Even hotter conditions are expected to our south and west

A partial lunar eclipse will occur late tonight as the moon gets enveloped by the Earth's shadow. Clouds may ruin viewing of the eclipse, but significant uncertainty remains about the degree of sky obscuration that may prevent the region from seeing moon obscuration.

Scattered showers and storms are expected area-wide this afternoon and evening, then across mainly the East Tennessee mountains and southwest North Carolina for Friday. A few storms may produce strong and gusty winds this afternoon, especially in the northern Tennessee valley. Hot and muggy conditions return to the area for early next week.
