Issued: Monday, May 12
Launch Weather Officer: Jim Sardonia, 45th Weather Squadron
Synoptic Discussion: "Conditions will remain favorable for (mobile launch platform) rollback this afternoon, winds will be light and there will be almost no chance of lightning within 5 nautical miles of SLC 41 today or tomorrow. All thunderstorm activity associated with the old frontal boundary to our north has ceased, and none is expected as the boundary moves through later tonight.
"Weather for tomorrow will be ideal for rollout and launch. Dry air behind the front will produce predominantly Clear skies and light northerly winds. Temperatures will only be slightly 'cooler' tomorrow with Highs in the mid 80's. The only slight concern for tomorrow is the chance of a few Cumulus clouds inland within 10 nautical miles of SLC 41 becoming enhanced by the sea breeze.
"In the event of a delay to Wed, 14 May, conditions worsen only slightly as an increase in temperatures and moisture is expected, increasing the chances of enhanced Cumulus Clouds on Wed afternoon."
