New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 1037 AM EDT Thu May 16 2024 Water vapor imagery highlights a broad belt of westerlies across the Gulf of Mexico and the northern Gulf Coast. The deep, mean- layer ridging centered over Panama is well to the south of its normal position. The low-level ridge axis extends west across Cuba. As such, steering and SFC winds are from the southwest.
Satellite derived moisture products place a narrow band of enhanced moisture over the eastern Gulf along a stalled frontal boundary. The Florida Keys are within a plume of drier air, nicely noted by SPC's 850 mb analysis. The forecast calls for high temperatures in the lower 90s this afternoon, well above normal (upper 80s) for this time of year. Dewpoints are a shade below yesterday's values, but still in the upper 70s. Heat indices will peak in the high 100s, so plan accordingly if working or playing outside. Per rain chances, the reverse cloud line bubbled a few showers along and in the lee of the eastern-most Lower Keys yesterday. We will hold onto 10% rain chances to account for a similar scenario today. The forecast is on track.

MARINE
Issued at 1037 AM EDT Thu May 16 2024 A weak frontal boundary to the north of the Florida Keys interacting with an area of high pressure in the western Atlantic will result in a somewhat chaotic wind forecast through the weekend. Breezes will tend to peak in the evening and overnight hours, and then lull in the afternoon hours. Rain and thunder chances will remain low through early next week.

AVIATION
(15Z TAFS)
Issued at 1037 AM EDT Thu May 16 2024 Cloud streamers are evident on GOES 16 Visible satellite data this morning oriented southwest to northeast. These cloud streamers may occasionally result in brief periods of MVFR conditions for CIGs around 020-025. Near surface winds are expected to remain southwest to west near 10 knots with occasional gusts to near 15 knots through the early to mid afternoon. Winds will shift sometime during the mid to afternoon to the west to northwest before becoming briefly variable during the evening and then southeast to south overnight.

CLIMATE
On this day in 1923, a daily record rainfall of 2.89 inches was measured at Key West. May rainfall records for Key West date back to 1871.
