Deep moisture, which has been confined to south FL, will begin returning northward today. Weak frontal boundary, which passed to the south several days ago, will return northward. This boundary marks the transition to the deep moist air mass. Any low pressure development near the Yucatan will remain well to the west as it moves northward. By Saturday, once the moisture is in place, normal local triggers (sea breeze, day time heating etc.) with result in the return of showers and thunderstorms. Main concern for the launch windows will be for remnant cloud cover associated with the showers and thunderstorms. <br /> <br /> <br /> <br />Clouds<br /> Coverage<br /> Bases (feet)<br /> Tops (feet)<br /> <br />SCT030<br /> 2/8<br /> 3,000 <br /> 6,000<br /> <br />BKN080<br /> 5/8<br /> 8,000<br /> 12,000<br /> <br />BKN250<br /> 6/8<br /> 25,000<br /> 27,000<br /> <br />Visibility:<br /> 7 miles<br /> <br /> <br /> <br /> <br />Wind:<br /> 160 degrees / 10 - 15 Knots<br /> Pressure:<br /> 30.06 IN HG<br /> <br /> <br /> <br /> <br />Temperature:<br /> 76 F - 78 F<br /> RH:<br /> 70%<br /> <br /> <br /> <br /> <br /> <br /> <br />Weather:<br /> Mostly Cloudy<br /> <br /> <br /> <br /> <br />Overall probability of violating weather constraints:<br /> 40%<br /> <br />Primary concern(s):<br /> Anvil Cloud Rule, Debris Cloud Rule, Thick Cloud Rule<br /> <br /> <br /> <br /> <br />Overall probability of violating weather constraints for 24 hour delay:<br /> 40%<br /> <br />Primary concern(s):<br /> Anvil Cloud Rule, Debris Cloud Rule, Thick Cloud Rule<br /> <br /> <br /> <br /> <br />Overall probability of violating weather constraints for 48 hour delay:<br /> 40%<br /> <br />Primary concern(s):<br /> Anvil Cloud Rule, Debris Cloud Rule, Thick Cloud Rule<br /> <br /> <br /> <br /> <br />Sunrise:<br /> 28 June 03 / 0628 EDT<br /><br />29 June 03 / 0628 EDT<br /><br />30 June 03 / 0628 EDT<br /> Moonrise/<br /><br />% illumination<br /> 28 June 03 / 0519 EDT / 1%<br /><br />29 June 03 / 0607 EDT / 0%<br /><br />30 June 03 / 0701 EDT / 1%<br /> <br />Sunset:<br /> 28 June 03 / 2024 EDT<br /><br />29 June 03 / 2024 EDT<br /><br />30 June 03 / 2024 EDT<br /> Moonset:<br /> 28 June 03 / 1947 EDT<br /><br />29 June 03 / 2042 EDT<br /><br />30 June 03 / 2133 EDT<br /><br /> <br /> <br />Next forecast will be issued:<br /> 28 June 03
