748 FXUS62 KKEY 060230 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1030 PM EDT Sun May 5 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1000 PM EDT Sun May 5 2024 Currently - A robust surface high aligned off the Atlantic Coast stretches southwest and west across the Gulf Coast States. This continues to maintain moderate to fresh easterly breezes across the Keys and surrounding waters. This evenings sounding indicated precipitable water has increased moderately over the past 24 hours. While surface dew points remain near 70, much of this moisture increase was concentrated at a number of lower level layers. At the same time, there are a couple of low level inhibition zones with warmer and relatively drier air. Consequently, all shower activity have been relegated to old sea breeze boundaries that moved into our waters west of mainland Monroe and also west of Andros Island. Short Term Update - Surface winds will remain moderate out of the east due to the broad ridge to our north holding steady. This consistent breeze will limit overnight cooling. Expect lows in the mid to upper 70s with dew points remaining near to slightly above 70. Recent satellite imagery is consistent with guidance in suggesting some lower level drying is moving in across the Keys. However, forecast soundings suggest that this will be subtle. At the same time, lower level inhibition is expected to weaken somewhat. As a result, a few showers nearer the island chain cannot be ruled out. Will maintain slight chance pops. && .MARINE...
