Area forecast discussion, Jul 1, 11:29 PM CDT, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1129 PM CDT WED JUL 1 2015

.AVIATION UPDATE...FOR 06Z AVIATION FORECASTS.

SCATTERED TSTMS ARE EXPECTED TO CONTINUE DEVELOPING OVER MIDDLE
TENNESSEE FOR THE NEXT SEVERAL HOURS, LIKELY BECOMING NUMEROUS
BETWEEN 09Z AND 13Z AS SEVERAL MESO COMPLEXES SPREAD IN FROM THE
NORTHWEST.

EXPECT MAINLY MVFR CONDITIONS AT AREA TERMINALS THROUGH THE
FORECAST PERIOD, AS AIR MASS REMAINS UNSTABLE AND CONDUCIVE TO
INTERMITTENT PERIODS OF TSTMS AND CIGS BTWN 25K AND 30K FT. EACH
TERMINAL SHOULD BE ABLE TO SQUEEZE OUT AT LEAST BRIEF PERIODS OF
VFR CONDITIONS WHEN TSTMS ARE LEAST NUMEROUS, BUT IT'S HARD TO
PREDICT THOSE PERIODS WITH ANY DEGREE OF CONFIDENCE. THIS WILL BE
A DAY WHEN PILOTS WILL NEED TO KEEP AN ESPECIALLY CLOSE EYE ON
RADAR TRENDS WHEN MAKING FLIGHT PLANS, AND STAY ABREAST OF ANY AND
ALL TAF AMENDMENTS.
