DISCUSSION.

. Band of Showers and Strong to Severe Storms Will Cross East Central Florida Early This Morning .

Current . Pre-frontal convective band extends from near Lake City to Cedar Key, and extends SW into the Gulf well west of greater Tampa. Strong mean H85-H50 wind max of 50-60KT is supporting a rapid ENE to E motion of about 50-55 MPH across the northern third of FL. Recent SPC mesoanalyses showed substantial erosion of the CIN in place over the peninsula (esp. western FL), while SBCAPE had risen to 1000-1500JKG-1, even a little higher to the west. Potential is in place for strong to isolated severe storms with straight line wind damage the greatest threat. Recent coord with SPC/TBW/JAX for the forthcoming SVR TSTM watch that will be in place from Brevard/ Osceola Cos northward through 16Z/11AM.

Today-tonight . Band of storms will reach Lake/Volusia Counties by 10Z/5 AM, move rapidly across the I-4 corridor around 7-8AM, and then across Osceola/Brevard Counties from 9-11AM. Band should weaken as it reaches the southern CWA into the early afternoon. Rapid end to precip and decrease, with skies rapidly clearing into tonight as gusty west winds immediately behind the front veer WNW by sunset. Max temps in the M70s north to L80s south. Clear and turning much cooler tonight with mins in the U40s-L50s most areas, some M-U50s far SE.

Sun/Sun night . Weak high pressure will be centered near the FL/GA border Sunday morning then scoot eastward into the western Atlc by Sunday night. Light northerly flow will veer quickly out of the east during the day, then Southeast Sun night. Dry airmass will produce clear skies with max temps in the mid 70s, except lower 70s along the Volusia coast and upper 70s around Lake Okeechobee. Min temps early Mon will be in the 50s, except low to mid 60s along the immediate coast due to the onshore flow.

Mon-Fri . The next mid level short wave carves out a larger trough across the central-eastern CONUS this period. Both GFS and ECMWF models push another strong cold front into Florida by Tue night, preceded by a band of showers. Above normal temps in the lower 80s Mon and Tue with scattered showers Tue aftn/night, possibly lingering into early Wed depending on timing of the next front. Turning noticeably cooler Wed-Thu behind the front with highs struggling to get out of the 50s across Lake/Volusia counties Wed with mid to upper 60s elsewhere. Temps slowly moderating Thu-Fri reaching the upper 60s and lower 70s. The coldest morning looks to be Thu with low to mid 40s Volusia and the interior counties and low to mid 50s Brevard-Martin counties.

AVIATION. AVIATION . 06Z TAF package included TEMPO groups for the band of strong storms reaching LEE-DAB 10-11Z, SFB 11-12Z and MCO-ISM 12Z-13Z. TEMPO TS may also be needed farther south, esp for TIX, but prefer to see how convection evolves before adding by the issuance time for the 12Z package. Also included 270/20G30KT for the northern aerodromes, which may need to be nudged up a bit depending upon vigor of the convective band in 2-4 hours.

MARINE. Today-tonight . stout westerly winds 15-20KT near shore and 20-25KT offshore will veer to NW and weaken later today into tonight. Capped seas at 7FT beyond 20NM given buoy data shows both wave models initialized about 2FT too high. SCA continues for all the offshore legs, with 4-6FT and a Cautionary Statement near shore. Conditions will improve pretty quickly tonight as winds diminish.

Sun/Sun night . High pressure center nearby Sun morning will push off the coast onto the western Atlc. North winds around 10 kt to start will veer Easterly by mid aftn, then increase 10-15 knots out of the E/SE Sunday evening and overnight. Seas 3-5 ft.

Mon-Wed . High pressure quickly pushes seaward into the western Atlc with a trailing ridge axis that pushes down the FL peninsula ahead of the next cold front. As a result, winds will veer out of the southeast and increase near 15 knots Monday and south to southwest Tue. Seas 3-5 feet. A cold front is forecast to push across the local Atlc waters Tue night/early Wed followed by an increase in NW winds near 20 knots. Seas will build quickly to 7 feet in the Gulf Stream on Wed.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
