Area Forecast Discussion National Weather Service Melbourne FL 942 AM EST Mon Nov 30 2020

UPDATE.

. A Few Strong Storms This Morning Across East-Central Florida . . Cold Temperatures Beginning Tonight through early Wednesday, with Frost Possible Wednesday Morning .

A strong cold front is making its way towards ECFL today, currently located in northern FL as of 9 AM. Ahead of the cold front, moving quickly to the southeast, is a line of showers and embedded lightning storms. The convective line stretches from Daytona to Kissimmee in our CWA and continues on down through Tampa's southern CWA.

The current forecast is on track, only made a few slight adjustment to the PoPs and cloud cover to better reflect the speed and timing of the convective band. Local impacts from the storms will be gusty winds up to 50 mph, with isolated gusts up to 60 mph possible, and lightning strikes. The trailing cold front is still expected to move south of I-4 around 11 AM, Melbourne by early afternoon, and clearing the Treasure Coast by around sunset. Highest rain chances (around 50-60 percent)will occur in the northern part of the CWA this morning, and will continue to move southeast throughout the day. As the convective band moves southeast, the band is expected to break up and weaken. Cloud cover this morning will be mostly cloudy along the north, and partly cloudy across the south. As the front approaches and the convective band moves SE, cloud cover will increase in the south, and will become mostly cloudy. Behind the front, cloud cover is expected to decrease, becoming clear to mostly clear this evening. Today's high temperature will reach in the low to mid 70s across the north and upper 70s to low 80s across the south. As the cold front passes the area, cool dry air will fall in behind it. Overnight lows will fall to the upper 30s to low 40s across the north, and mid to upper 40s across the south, except along Martin county where lows are expected to reach 50.

Aviation. A strong cold front is making its way to ECFL, brining with it shower and embedded strong storm out ahead of the front. As of 9 AM, the convective band is stretching from Daytona, to Kissimmee and on down through Tampa's southern CWA. Included VCSH for all sites, except KLEE since convection has moved passed that terminal, starting in the northern terminals at 12Z and increasing in time farther south. Included TEMPO groups with MVFR CIGs/VIS TSRA and wind gusts 20-25 KT, starting in the northern terminals and going out in time southward. Did not include TEMPO groups for KVRB southward, as convection is expected to weaken by the time it reaches those terminals, so just included VCSH for those terminals. As cold front moves through the area, cool dry air will fall in behind it. Convection is expected to clear southern terminals by early this evening. Winds will be gusty this afternoon, around 20 KT out of the W, before dropping off this evening to around 10 KT across all terminals. Seas will build to 4-6 FT this morning and briefly reach 7 FT in the far northern offshore waters this afternoon, before further increasing to 4-6 FT in the nearshore and 6-8 FT in the offshore waters this evening.

Marine. As of 9AM showers more moving in a general eastward direction around 20-30 KT. A small craft advisory is now in effect across all local waters. Winds will be from the NW and are forecast to briefly fall below 20 KT this morning and afternoon, but will increase back to 20-25 KT by this evening. Seas will build to 4-6 ft this morning, with seas reaching 7 ft in the far north offshore waters this afternoon, before further increasing to 4-6 ft in the nearshore waters and 6-8 ft in the offshore waters by tonight.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
