Area Forecast Discussion National Weather Service Houston/Galveston TX 606 AM CST Sat Dec 14 2019

AVIATION. VFR through the day into evening hours . calm to light breezes waking up from the east and veering light onshore this afternoon. Increasing lower level moisture within a cooling near surface layer will pick up the probabilities of lowering cats to MVFR as ceilings fill in and fall to around 2k ft after midnight. MVFR with more isolated IFR decks with MVFR visibility-reducing haze or light fog will impact many regional terminals before and through Sunday sunrise. 31

PREV DISCUSSION. /ISSUED 349 AM CST Sat Dec 14 2019/

SHORT TERM [Through Sunday] . Mainly clear overnight Saturday morning skies has allowed a few sites' temperatures to fall to within a degree or two of their respective dew points. This has created very isolated radiative fog to form over the Angleton and Cleveland areas. Light northeast breezes behind yesterday's washed out boundary will veer around the eastern side of the dial and become onshore through the day. This warmer flow will have regional temperatures warming back up into the areawide middle to upper 70s by early afternoon. Increasing boundary layer moisture will assist in keeping Sunday morning's temperatures around 10 degrees warmer than tonight's minimums (in the mid to upper 40s). The onshore pressure gradient tightens evermore on Sunday to produce a stout southerly wind. Despite windier conditions and thickening cloudiness Sunday, areawide temperatures will warm into the areawide lower 80s. These unseasonably warm conditions will flirt with maximum temperature records (see Climate section below). 31

LONG TERM [Sunday Night Through Saturday] . Sunday night will be our last "warm" night as some spots struggle to fall below the mid to upper 60s (these lows are actually close to the normal high temperatures for mid December). Expect to see increasing shower coverage (maybe an isolated thunderstorm or two) starting after midnight as instability begins to increase ahead of the next cold front. Best shower/thunderstorm chances come on Monday as the front sweeps through the northern counties in the morning, central counties in the late morning or early afternoon and off the coast in the afternoon. Look for temperatures to fall behind the front (and rains to come to an end) with readings likely to drop into the 50s (especially up north) in the afternoon. Drier and much cooler weather will take over beginning Tuesday night through Wednesday night with lows as cold as the upper 20s/lower 30s inland and highs in the 50s. A slight warm up can be expected in the Thursday/Friday time period (lows in the 40s/50s and highs in the 60s) while the next storm system moves across the state and brings parts of the area some rain. If the timing is right, next weekend should end up dry with cool nights and mild days. 42

MARINE . Seas have leveled off at around 2 feet under weak winds to begin the weekend. After a day of light and variable winds, southerly winds will return and strengthen to caution levels tomorrow in response to lowering western Texas pressure. Seas lift back to 3-4 feet nearshore . 4-6 foot offshore heights by Sunday afternoon. A strong cold front is forecast to travel across the waters late Monday night. North winds and seas will significantly strengthen and lift respectively to Advisory levels Tuesday. Strong cold air advection coming across the waters behind the front will maintain a tight enough offshore pressure gradient to keep winds and seas at Advisory levels through Wednesday morning . falling off through the afternoon into evening hours. Surface high pressure re- positioning itself over the southeastern U.S. will veer light winds around to onshore by Thursday. 31

CLIMATE . Near record high temperature are possible on Sunday (12/15). Here are some record highs and their date of occurrence:

CLL . 84/1924 IAH . 82/1995 HOU . 81/1995 GLS . 77/2012

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.
