Area Forecast Discussion National Weather Service Houston/Galveston TX 1135 PM CST Sat Dec 14 2019

AVIATION. Ceilings have developed and deteriorated much faster than expected with a blanket of IFR ceilings over all but the southernmost TAF sites. A persistent onshore flow will continue to bring low level moisture into the region beneath a strong cap. Winds will not decouple tonight so expecting low stratus for much of the night into early Sunday. Winds will increase further and there should be enough heating to lift ceilings by afternoon with a mix of MVFR/VFR ceilings. Sea fog may develop toward evening at KGLS. Not sure if ceilings will redevelop toward evening and kept things VFR for now. Introduced a VCSH for KIAH for the last six hours of the TAF period. 43

PREV DISCUSSION. /ISSUED 1000 PM CST Sat Dec 14 2019/

UPDATE .

As winds shifted southerly this afternoon/evening, warm and moist air mass from the Gulf filtered into the region. Low level moisture has increased dewpoint values sufficiently enough to create favorable conditions for fog development tonight through Sunday morning. Earlier dewpoint/temperature/wind analysis showed southern regions affected by fog starting near midnight, spreading into the central and northern regions a few hours thereafter. Well, it began even earlier than expected. Areas of fog have already been spotted over portions of Brazoria, Galveston, Harris, and Fort Bend counties and it continues to spread out. However, winds look to pick up as the pressure gradient tightens. This may not allow for dense fog to stick as much over these areas. The fog is expected to lift during the morning hours Sunday, but could re-appear along areas near the bays and coasts due to possible sea fog formation Sunday evening. Onshore flow will prevail Sunday, continuing the warming trend across SE Texas. High temperatures Sunday afternoon will reach the low 80s across most of the region, slightly cooler along the coasts and Barrier Islands. No rainfall is expected, but will remain party to variably cloudy.

Main Changes: Updated the temperatures to better represent the current observations. Included patchy fog for the Brazoria, Galveston, Harris, and Fort Bend counties a few hours earlier from what was previously forecasted. The rest of the forecast remains unchanged. 24

Marine .

Winds will increase tonight as the pressure gradient tightens, and in turn elevate seas; SCEC flags have been issued for the offshore waters through 5 AM CST.

Dewpoints will be increasing to near 70s Sunday and with water temperatures around 64, there is potential for sea fog to develop across the bays and nearshore Gulf waters during the evening through Monday morning. Fog development will cease with the passage of the next cold front Monday, as drier and colder air mass moves into the local waters. 43/24

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
