Title:

Eastern Range Operations Forecast Op Number:  F8615 Issued:  21 Aug 03  0930 EDT 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:

Deep tropical air mass remains entrenched over FL.  Light S-SW steering flow will result in early development and inland penetration of the east coast sea breeze.  This will result in a majority of showers and thunderstorms remaining west of I-95.  Weak frontal boundary approaching from the north will be over FL-GA border over the weekend, and dissipate over northern and central FL by Monday.   A southeasterly flow reestablishes itself on Tuesday as a tropical wave approaches from the SE.  This wave is expected to remain south of the area.  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.
