Title:

Eastern Range Operations Forecast Op Number:  F8615 Issued:  23 Aug 03 Valid:   25 Aug 03 (0135 EDT) Note:  Forecasts available on the 45th Weather Squadron web site at: https://www.patrick.af.mil/45OG/45WS/

Vehicle/Payload:

Delta II / SIRTF

Location:

Pad 17-B

Launch Weather Officer:

Joel Tumbiolo

Synoptic Discussion:

Weak and dissipating frontal boundary approaching from the north will be move through central FL over the weekend, before returning northward during the day on Monday.  Main threat for thunderstorms along the east coast will be Saturday.  By Sunday, winds turn E-NE and all thunderstorm activity will remain west and south of the area.  Forecast beyond Tuesday will depend on evolution of the strong tropical wave (former TD #9) as this system has the potential to redevelop. Main concerns for the instantaneous launch window will be the proximity of residual cloud cover associated showers and thunderstorms that develop during the afternoon and evening hours.
