Discussion A highly amplified pattern has set up over the east coast. Sharp mid- upper level ridging has slipped off the east coast and extends from the bahamas northward through the new england states and into quebec. Deep troughing extends south through the mississippi river valley and into the northeastern gulf of mexico. This trough will lend support to the weather system moving through the florida panhandle this morning and expected to move through the florida peninsula later today. The trough will exit to the northeast late Friday evening into Saturday morning as a zonal pattern sets up over the southeast u.S. Through the weekend. Strong upper ridging builds over florida late Monday into Tuesday and will persist through most of next week. On the surface, an area of low pressure and associated frontal boundary moves eastward across northern florida. Latest radar imagery is showing the stronger storms moving through the northern coastal waters and levy county. SPC continues to hold most of the florida peninsula in a marginal risk for severe weather today. The greatest threat will be damaging winds with passing storms. Storms are currently moving through the nature coast, with the latest hrrr model guidance slowly progressing the storms southeastward through central florida late morning early afternoon and exiting southwest florida by the early evening. High pressure builds in behind this front on Saturday and will persist through all of next week producing rain-free conditions and warm weather. Aviation Vfr conditions expected to prevail through around 15z. As the front approaches the northern terminals at that time, some brief MVFR ifr CIGS and vsby restrictions will be possible at tpa pie lal srq, then becomingVFR between 18-21z. Some brief MVFR ifr CIGS and vsby restrictions will be possible for the southern terminals at pgd fmy rsw a little later around 18z, then becomingVFR between 21- 00z. S-se wind at |
8-10 knots expected overnight until around 12-15z, then becoming gusty around 15 knots with gusts approaching 20-25 knots as the front moves through. Winds shift to the west- northwest after 16z and decrease to around 10 knots. No other aviation impacts expected. Marine A frontal boundary moves through the coastal waters through the day producing high chances of showers and storms and increasing winds around 15 knots and seas around 3-4 feet. Mariners should take caution when operating in the gulf waters today. The winds will shift to the north-northwest in the wake of the front by early Saturday morning. High pressure moves into the area by Saturday afternoon and will persist into next week. Tranquil boating conditions with winds less than 10 knots and seas less than 2 feet can be expected starting Sunday and continuing through next week. No other marine impacts are expected. Fire weather Abundant moisture will keep humidity values above critical levels through the end of the week with no red flag conditions expected. High rain chances can be expected today as a cold front moves through the region. Increasing 20 foot winds and transport winds in the vicinity of the front will support high dispersion indices across the forecast area today. Drier air will move in behind the front on Saturday with some rh indices dropping below 35 percent, but winds and erc values will not meet red flag criteria. No other fire weather concerns are expected.

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. |
