NWS Miami, FL wrote its last area forecast discussion before the first event at May 13, 12:41 PM EST, 4 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 141 PM EDT Sat May 13 2017 .AVIATION...Expect all east coast sites except KTMB to go SSE or SE by 19Z at 10-13kts with seabreeze. KAPF and KTMB remain SSW 10-12kts. All sites may see gusts to 20kts through sunset. Isold TSRA/SHRA with late afternoon seabreeze collision along east coast, with best chances near KPBI where have added VCSH 22Z-00Z. Winds diminish and become SSW 5-8kts after 00Z. Front approaches late tonight, with VCSH for KAPF after 14/09Z, and for KPBI-KFXE- KFLL after 14/15Z. TSRA threat too low to mention at time, but may need to be added later as front approaches. && .PREV DISCUSSION... /issued 1020 AM EDT Sat May 13 2017/ UPDATE...South-southwesterly flow is already picking up across the region late this morning, and expect another hot and breezy day for most locations. As with yesterday, no records are expected, but temperatures will continue 4-5 degrees above normal. The southerly flow has brought an increase in low level moisture, though not in the mid levels as the morning sounding still shows a very dry atmosphere above 850mb. With dewpoints back in the upper 60s and low 70s, afternoon temperatures will feel more like in the mid 90s at times. Band of convection moving into the the Nature Coast well ahead of the main cold front this morning looks to remain out of our area today, but it's forward progression will have to be watched in addition to any outflow boundaries it produces. With a little more moisture, we could see a few showers or storms along the east coast late afternoon/early evening where the seabreeze collision takes place. The overall threat remains isolated at this time. Any significant increase in rain chances look to hold of until late tonight as the main cold front approaches. PREV DISCUSSION... /issued 331 AM EDT Sat May 13 2017/ DISCUSSION...Low pressure centered over Mississippi with associated cold front stretching from the low south into the northern Gulf coast. This low pressure will gradually make its way into the Florida Panhandle shifting the low level flow more southerly overnight. This as a result, will act to increase moisture tonight. This in addition to the moisture will enhance patchy areas of fog tonight mainly over the northern counties. During the day, southerly flow will increase from south to southwest as the gradient strengthens across South FL. A southwest flow pattern will act to raise temperatures along the east. Dewpoints in the upper 60s combined with max temperatures near 90 degrees will lead to heat indexes from the low to mid 90s. Front still remains north of the area keeping most of the convection out of the area with dry conditions continuing for one more day. Mother's Day, both the GFS and ECMWF prog the cold front to press over southern Florida continuing the trend of higher pops over South Florida for most of the day. Expect showers and a couple of thunderstorms along the eastern metro areas with fropa Sunday. In the evening, the front should be exiting the area clearing conditions over Palm Beach, Broward and most of the northwest counties. There will still be some lingering moisture over the southern counties continuing the chance of isolated showers Sunday night. Long Term (Monday-Friday): Lingering moisture associated to the front will remain over the area with light southerly flow over the peninsula. This will help develop both sea breeze through mid week. Surface high pressure over the Atlantic will strengthen Wednesday increasing easterly flow across South Florida. Temperatures will remain around the upper 80s to low 90s through much of the week. MARINE...Low pressure approaching the region will increase southwest to southerly flow through the day with the potential for SCEC conditions to develop over the Atlantic. The southerly flow decouples in the evening hours and shift southwest into Sunday with the approach of the front to South FL. Showers and some isolated thunderstorms will be possible Sunday over the coastal waters and begin to diminish into the late evening as the front exits and moves further south. Southerly winds and seas remain low through the weekend and early next week. By mid week, ridge strengthens over the Atlantic waters shifting winds to the east. Gradient will gradually strengthen with SCEC conditions returning and increase close to SCA by the end of the week. FIRE WEATHER...High pressure will continue to bring dry and warm weather through Saturday. Relative humidity will be on the increase through the day but values over Glades County could see brief periods of RH between 35 to 40%. Therefore, Fire Weather Watch remains. Gusty south- southwesterly flow is expected to increase on Saturday, leading to very good to excellent dispersions across the region. There will be a chance of showers and thunderstorms on Sunday as a front approaches South Florida. && .PRELIMINARY POINT TEMPS/POPS...
