Latest Aviation Discussion:

.AVIATION /06Z TUESDAY THROUGH SATURDAY/... Canadian high pressure will support VFR conditions through mid- week. Weak gradients keep lighter winds than yesterday/Monday, with winds gradually shifting from east to southeasterly today. This ridge eventually edges toward the Atlantic coastline which will support mainly southerly winds on Wednesday into Thursday. Some storm chances emerge by Thursday, but these are currently expected to stay west of the area terminals. A cold front moves through early Friday which results in some uptick in shower chances. This may come with a few restrictions if convection becomes more pronounced. In the wake of this frontal passage, winds turn more northerly with afternoon gusts to around 15 knots or so. High pressure building to the north results in a east to southeasterly wind for Saturday. This comes with likely VFR conditions. AVIATION...BRO Update as of: 349 AM EDT Tue Sep 15 2026
