SHORT TERM. As sfc high pressure moves east, return flow and moisture depth will begin to move back to the area. A very weak frontal boundary will settle just north of the area before stalling Thursday. Most of the weather this boundary will help produce will be north of the area but we could still see some showers move through from time to time starting Thursday. The biggst question here will be fog. This morning looks to be the best chance of it developing. Tonight should be mostly cloudy to cloudy which take away the radiation part but the cooling could come from the water. If this is the case, there could be some fog around by Thursday morning as well.
LONG TERM (Saturday through Tuesday). As shortwave wave exits the region Friday night, strong upper level ridge will begin building across the Gulf of Mexico and spreading northward. The strength of this high pressure system will determine rain chances. If its on the stronger side, it will generally shield most of the area from rain to the north. If not, troughs passing west to east, north of the area, bring rain farther south and into the CWA. Current forecast is slightly wetter than previous but still on the drier side of guidance. Either way, increasing 500mb heights will allow temps to substantially rise over the weekend. Could be looking at highs in the low 80s in a few locations Sunday. Will be keeping previous forecast trend of high temps above NBM and closer to the MEX.
Uncertainty increases rolling into next week. Global models are struggling with resolving the next trough which may be a faster moving shortwave or a slower moving deep upper low. With such big differences in solutions, will just stick with NBM blend.

AVIATION.
VFR through this taf cycle. Some -RA may begin to affect a few terminals by the end of this cycle though. There will also be a chance that a few sites observe some reduction in vis by late tonight as well.
MARINE.
Southerly winds are expected to remain light trough the end of the week. A cold front could move through the northern gulf during the first half of next week bringing some sh/ts and strong northerly winds.

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. |
