DISCUSSION
HEY TIM,
HERE'S THE FORECAST WE DISCUSSED. 20FT WINDS AND TRANSPORT WINDS
ARE REALLY GOING TO STRUGGLE TOMORROW AS HIGH PRESSURE MOVES IN.
ALL OF OUR DISPERSAL INDICES ARE BEING IMPACTED BY THOSE NEARLY
NON-EXISTANT WINDS.
HIGH PRESSURE MOVING THROUGH THE AREA WILL ALSO BRING PATCHY FROST
TO THE OCONEE TOMORROW. BUT FRIDAY WILL MARK THE BEGINNING OF A
WARMING TREND THAT WILL CONTINUE INTO THE WEEKEND. AS TEMPS HEAT
UP, WE SHOULD SEE THOSE SOUTHWEST WINDS PICKUP AS WELL IMPROVING
DISPERSION RATES ACROSS THE BOARD.
QUICK NOTE: WE'RE HAVING SOME PHONE PROBLEMS IN THE OFFICE, IF YOU
NEED ANYTHING JUST CALL MY CELL.
