AVIATION. IFR/LIFR conditions will possible at southern terminal for a few more hours. After that fog and CIGS will lift and we can expect VFR conditions through the TAF period at all sites. Winds will remain out of the north and northeast and stay below 15kts for the next 24 hours.

Prev Discussion. /issued 300 AM EST Sat Jan 25 2020/

DISCUSSION . A deep low pressure system currently just north of the Ohio Valley tracks northeastward into southwest Quebec on Sun . trailing a cold front across the area early this morning and into far south FL during the afternoon. The front stalls along the Florida Keys and stretches northwest over the Gulf of Mexico tonight. High pressure builds in along the central Gulf coast today then tracks to FL and the adjacent Atlantic waters Sun afternoon. There have been isolated light showers that have occasionaly pushed inland along with patchy fog and low cloudiness ahead of and along the front . but these continue to track south and will clear central locations around daybreak and exit southern locations around 10 am or so. Behind the front dry and stable air filters in on northwesterly lower level flow that gradually becomes northerly and diminishes. Temperatures start off around normal but then slowly drop . to about 5 degrees below normal on Sun.

Sun night through Fri: Broad and relaxed cyclonic flow aloft dominates the central and eastern states for most of the period. An embedded short wave trough scooting along the northeast Gulf coast and north FL Sun night-Mon along with a weak wave/low forming on the Gulf front will support a chance of showers. A second short wave trough slides by just to the north Wed with some low chances of showers. A third short wave trough deepens into a low over the western Gulf coast Fri . with a surface reflection trailing a front south across the Gulf. Showers will be on the increase for the end of the week. Temperatures will run slightly below to near normal.


MARINE . High pressure behind a cold front tracking south through the waters today will support some exercise caution winds . 15 to 20 knots . on Gulf waters. The high settles in and shifts across the state during the rest of the weekend with veering and diminishing winds. A weak low moves in from the western Gulf for the start of the week with scattered showers. After today winds are expected to stay below headline criteria.

FIRE WEATHER . Drier air working in today will drop the min RH to less than 35 percent for many inland locations today and also Sun. However durations will be limited . perhaps 3 hours only down south . with light winds and low ERC values in most counties. Red flag conditions are not expected. Moisture begins to recover Mon with the RH above critical levels for the rest of the week. No significant fog is expected for the next couple of nights.

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.
