.DISCUSSION...
Issued at 103 AM EST Wed Nov 12 2025

Auroral and starry skies have been gracing across the region so
far tonight, with gusty winds at times lending to another cold
night. Clear to mostly clear skies are expected to remain until
late tomorrow night when patchy fog and high cirrus both may be
building in. So, should tomorrow evening also have aurora
potential, the local weather here looks favorable again for
viewing.

This week is dry, with upper ridging to our west and high pressure
in the southeast and later Ohio River valley keeping us dry.
Nonzero chances off a very weak shortwave for rain in southwest
Virginia Friday night, but any rainfall would be negligible. A
front sweeps much of the Eastern US Tennessee and north on Sunday,
but southward extend looks to be limited. This should equate to
mild weather continuing into next week, where confidence is lower
on how the next rainy system will evolve from the west.
