AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MORRISTOWN TN
915 PM EDT MON MAY 20 2013

.DISCUSSION...
MINOR TWEAKS MADE TO THE FORECAST THIS EVENING AS MOST EVERYTHING
APPEARS TO BE ON TRACK. GIVEN THE LATEST OBS/TRENDS...OPTED TO
REMOVE THE LOW-END MENTIONABLE POPS FROM THE FAR NORTHEAST AND
MOUNTAIN ZONES AS ALL CONVECTION HAS REMAINED EAST OF THE MOUNTAINS
IN NC AND IS DISSIPATING WITH THE LOSS OF DAYTIME HEATING. GIVEN
THE MOIST BOUNDARY LAYER CONDITIONS AND CALM WINDS...THE POTENTIAL
FOR AREAS OF FOG TO FORM /ESPECIALLY IN THE USUAL FOG-PRONE AREAS/
SEEMS REASONABLE AS HAVE ADDED A MENTION OF THIS AFTER 08Z. ALSO
LOWERED TEMPERATURES A DEGREE OR SO GIVEN THE EXPECTED CLEARER
CONDITIONS WHICH SHOULD RESULT SOME SLIGHTLY BETTER RADIATIONAL
COOLING.
