The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS San Juan, PR wrote its last area forecast discussion before the first event at Jun 15, 3:28 PM AST, 32 minutes earlier.
Area Forecast Discussion...CORRECTED National Weather Service San Juan PR 328 PM AST WED JUN 15 2016 .SYNOPSIS...Low to mid level high pressure will maintain a stable atmosphere through at least the end of the work week. In addition...Saharan Air Layer is still present over the area...keeping a dry air mass and subsidence at mid levels. This will help to limit the vertical development of the clouds across the local region. Pattern will change during the weekend as a tropical wave enters the Eastern Caribbean Region...increasing somewhat the potential of showers across the islands. && .DISCUSSION...Fair weather has prevailed once again across Puerto Rico and the U.S. Virgin Islands today. Hazy skies have been observed but visibilities have remained greater than 6 miles across most of the area. No shower activity have been observed across the islands so far this afternoon. If any showers form will be short-lived as very stable conditions prevail across the local area. Similar pattern expected tonight and overnight...with little or no shower activity affecting the islands. Stable pattern will prevail most of the work week as Saharan Air Layer remains over the area...limiting the development of showers across the local region. Southeasterly flow will keep warm to hot temperatures across most of the islands over the next few days. Moisture bands embedded in the trade winds will move at times between Friday and Saturday...allowing scattered showers to develop across portions of PR/USVI. The next surge of moisture is associated with a tropical wave. At this time...operational models suggest that the moisture associated with the tropical wave will likely reach the local region on Sunday. Therefore...showers and thunderstorms will likely affect the local islands as the wave passes by. && .AVIATION...VFR conds will continue through the forecast period. Winds will continue from the east-southeast between 10-15 knots. Sea breeze variations will continue thru at least 22z across northern/northwest PR. && .MARINE...Tranquil marine conditions expected over the next few days. Winds of 10-15 knots and seas of 2-4 feet with occasional seas of 5 feet will prevail across most of the local waters. && .PRELIMINARY POINT TEMPS/POPS...
