000 FXUS64 KHGX 052344 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 544 PM CST Sat Dec 5 2020 .AVIATION [00Z TAF Issuance]... Fairly challenging short term forecast, but fortunately most of the nuances are not very high impact. Uncertain how far north from the coast showers will stretch, so have at least VCSH everywhere, with prevailing as far as IAH. There is a chance at briefly seeing some MVFR CIGs late tonight into tomorrow morning, particularly closer to the coast. Hint at this with some cloud mentions at MVFR height, but stay VFR for now as low levels have had a hard time saturating. && .PREV DISCUSSION /Issued 335 PM CST Sat Dec 5 2020/... .SHORT TERM [Tonight Through Sunday Night]... Some spotty showers still linger across the area today and through the night with more concentration along the coast. Troughing along the coast still expected to develop tonight as low pressure moves into NETX tomorrow morning. Very little measurable accumulation is expected with the showers. High pressure will build into the area throughout the day tomorrow and rain chances diminish through the morning. Skies will clear through the day as the upper levels dry out with a northerly wind flow setting in. Tonight, lows will drop in the upper 30s in the northwestern counties as skies clear early in the morning. Along I-45 and south of I-10 will get into the low 40s and around 50 at the coast. Tomorrow, mostly clear skies and drier air will allow the area to warm into the low to mid 60s and then drop to around 40 at night. Light westerly winds tonight will veer from the northwest tomorrow through the end of the weekend. 35 .LONG TERM [Monday Through Saturday]... Clear, dry, and cool conditions will persist through the middle of next week as the dominant upper trough over the central CONUS pushes eastward and surface high pressure takes hold across SE Texas. Through Wednesday, a gradual warming trend is expected as offshore flow erodes, with southerly winds eventually developing by Thursday as the aforementioned surface high slides to the east. As a result, highs should warm from the lower 60s on Monday to just over 70 by Wednesday. With the synoptic pressure gradient tightening as a deepening lee cyclone forms over the eastern Rockies, moisture will be on the increase by Thursday with dew points recovering to the 50s/low 60s in the evening hours. Global models have come into a bit better agreement regarding the approach of our next upper low/surface cold front at the end of next week. ECMWF/GFS both place a closed 300mb low over Baja California by early Thursday, with both solutions now bringing it quickly towards SE TX as a longwave trough by late Friday/early Saturday. As an associated surface cyclone pushes through the Central Plains, both models show a cold front extending from this feature making its way into SE TX on late Friday/early Saturday. Given the more ample moisture expected to be in place (total PWs around 1.5 in), showers and thunderstorms should accompany the fropa. Models begin to diverge around Day 7-8, with GFS indicating a reinforcing front which brings a second round of precipitation to the area while the EC favors a drier weekend. Cady .MARINE... Troughing along the coastline will cause a brief period in increased winds close to caution level in the southern waters. Along with the peak in seas to 4ft, the winds will calm Monday evening to a northerly flow around 10KTs or less. Seas will subside through Monday to around 2-3ft and by mid week to 2ft or less through the end of next week as onshore flow pattern sets in by the end of the week. At the end of next week, higher winds and build seas are looking to be around advisory levels. 35 && .PRELIMINARY POINT TEMPS/POPS...
