Area Forecast Discussion National Weather Service Houston/Galveston TX 616 AM CST Sun Feb 23 2020

AVIATION.

Ceilings will gradually lower to MVFR categories during the daytime morning hours and remain in this category through early Monday morning. While there may be a few spits here or there today the mentionable chance of rain (showers) will not begin until near the end of this period . or after 09Z Monday as the region falls just downstream of the next cold front. Late period pre-sunrise Monday morning IFR decks are also possible in-line with increasing rain chances focused over more metro and southern area terminals. 31

PREV DISCUSSION. /ISSUED 413 AM CST Sun Feb 23 2020/

SHORT TERM [Today through Monday] .

Strengthened onshore winds will increase moisture through the day as this cloudier morning commences on a slightly milder note; lower to middle 40s over the northeastern third of the CWA to near 50 F over the southwestern forecast area. Clouds will be thickening from the southwest-to-northeast but, despite the thicker cloud cover, afternoon temperatures should warm into the upper 60s to lower 70s under enhanced warm air advection. There will be slight chances for very light rain showers or sprinkles this afternoon. The approach and passage of a weak cold front tomorrow will significantly increase tonight's shower chances . high southern third CWA rain chances from early Monday morning through early afternoon. Primarily morning showers with increased chances for isolated storms later in the morning/early afternoon over more southern counties in association with frontal forcing within weakening mid layer capping. Post-frontal northerly winds kick in Monday evening, thus allowing another overcast day to warm into the areawide lower 70s. 31

LONG TERM [Monday Night through Sunday] .

The first cold front will finish moving through the coastal waters Monday evening. It will be dry and cool behind this front with Tuesday morning's low temperatures some 10 to 20 degrees cooler than occurred on Monday morning. Before any significant moisture has a chance to return to the area and produce any rain, a stronger cold front will race on through Tuesday afternoon through Tuesday evening with much drier/cooler temperatures developing in its wake as a northwest flow aloft sets up. Similar to our last strong front, it looks like it could end up being breezy inland and windy near the coast Tuesday night through Wednesday, and wind advisories might be needed. Besides the winds, it will also be turning colder behind the front with Wednesday through Sunday low temperatures generally in the 30s/40s (Thursday morning looks like the coldest). For highs, 50s/60s on Wednesday-Thursday-Friday will warm up into the 60s/70s over the weekend as surface high pressure initially moving into the area gradually works its way off to the east. 42

MARINE .

Onshore flow has returned and will strengthen to Caution levels across more offshore Gulf waters today. While winds are not expected to reach Caution levels over cooler nearshore / bay waters, they may occasionally gust to Caution levels. Two fronts will cross the local waters this week; a weak front late tomorrow into early Tuesday and a much stronger boundary passage Tuesday night/Wednesday morning. This first frontal passage tomorrow will increase afternoon shower/isolated storm chances while the mid-week stronger (dry) frontal passage will significantly strengthen offshore flow in its wake. A much colder air mass descending down over the warmer Gulf waters will ensure a Wednesday of very strong northerlies that will likely frequently gust near or above gale force through the day. 31

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.
