Midday update...and for aviation
Updating the forecast package to take morning wording out of
zones. Scattered convection really starting to take off now...so
will have low chance probability of precipitation east and high chance/likely west-northwest.
Update out soon.
Aviation...for 18z tafs
Upper level low spinning over NE Arkansas will bring scattered rain showers/thunderstorms and rain
mainly to ckv and bna from 17z through at least 22z. Convection
thereafter should start to diminish and weaken. From now through
roughly 00z though...sct-bkn clouds around the MVFR/VFR threshold
will affect ckv and bna. Think most convection will stay west of
csv...though the clouds there could still briefly dip into the
MVFR category. Any storm that affects ckv or bna will drop visibilities
into IFR briefly.
Light fog will be possible overnight so will keep the MVFR br
mention in at ckv/bna. May remove the thunderstorms and rain mention in at csv
overnight...not confident in that timing at this point.
