Forecast for Wednesday, June 21

Issued: Tuesday, June 20 Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron Synoptic Discussion: "Continued no changes to forecast reasoning with overall favorable conditions expected. Surface high pressure ridge axis will be positioned north of the region, resulting in a continuation of low level layer easterly flow. This pattern typically indicates early sea breeze development which moves quickly inland during the afternoon. Westward moving late morning, early afternoon thundershowers along the coast and afternoon inland thunderstorms accompany this pattern. Easterly wave over the Bahamas will slowly move westward but is not expected to affect FL until possibly late Thurs, more likely Friday timeframe. At the beginning of the launch window most of the activity will be concentrated over the central interior and western half of the FL Peninsula. "Main concerns are offshore Cumulus Clouds and showers moving westward, and Anvil Clouds from thunderstorms over interior FL." Clouds: Cumulus Scattered at 3,000 feet and tops at 10,000 feet; Altocumulus Scattered at 12,000 feet and tops at 15,000 feet; Cirrus Scattered at 25,000 feet and tops at 26,000 feet Visibility: 10 miles Launch Pad Winds: Easterly from 080 degrees at 10 gusting to 15 knots Temperature: 82 to 84 degrees F Relative Humidity: 70 percent Weather: Showers in the vicinity offshore; Isolated thunderstorm west Probability of Violating Weather Constraints: 30 percent Concerns: Anvil Cloud Rule, Cumulus Cloud Rule
