DISCUSSION...HIGH PRESSURE WILL CONTINUE TO DOMINATE THROUGH
MIDWEEK WITH A LOW PRESSURE SYSTEM EXPECTED TO ARRIVE ON
THURSDAY. VERY WARM TEMPERATURES AND BONE DRY CONDITIONS WILL BE
THE NORM FOR THE NEXT FEW DAYS WITH WINDS PRIMARILY DRIVEN BY
DIURNAL SLOPE FLOWS AT THE HENRIE KNOLLS SITE. ALTHOUGH
TRANSPORT WINDS WILL REMAIN ON THE LIGHT SIDE...CLEARING INDICES
WILL REMAIN EXCELLENT DURING THE DAYTIME HOURS DUE TO SIGNIFICANT
LOW LEVEL INSTABILITY. SAID INSTABILITY WILL ALLOW FOR AFTERNOON

AFTER 1200. THIS SAID...NOT LOOKING FOR ANY WETTING POTENTIAL.
