000 FXUS64 KHGX 080325 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 925 PM CST Wed Mar 7 2018 .DISCUSSION... Only adjustment made on the evening update was to add a little extra cloud cover for the cirrus streaming into the area from the northwest. Mid-evening temperatures range from mainly the mid 40s well inland to around 60 at the coast. If cloud cover does not get out of control, we should have no problem reaching our expected morning lows of the mid to upper 30s inland and the upper 40s to around 50 at the coast (record lows/year set are 25/1932 for College Station, 27/1971 for the City of Houston, 31/1996 for Houston Hobby and 33/1996 for Galveston. 42 && .PREV DISCUSSION... /ISSUED 543 PM CST Wed Mar 7 2018/ AVIATION... VFR. Northerly breezes to weaken tonight and wake up from the east veering southeasterly by tomorrow afternoon. Cirrus decks will likely transition to mid-level ceilings by the PM hours. 31 PREV DISCUSSION... /ISSUED 357 PM CST Wed Mar 7 2018/ DISCUSSION... No significant changes were made to the forecast package this afternoon. Mclear skies, dry atmos and light winds should allow for a fairly quick temp drop this evening and good radiational cooling overnight. Water vapor imagery shows a large area of mid/high Pacific moisture rounding the top of the H5 ridge over the southwestern states. This cloudiness should eventually take a more southeastward track and overhead on Thurs. May need to make some downward adjustments to high temps tomorrow should it arrive earlier and/or thicker than currently progged. Slightly deeper llvl moisture returns Friday as surface high pressure drifts further east of the area. With a lack of a distinct focusing mechanism we`d generally expect some sct waa type shra and embedded tstms. Guidance does show an approaching jet streak Friday night into Saturday, so we may see more support/coverage during that time period across the southern parts of the area and offshore. Later in the day Saturday llvl winds veer more to the sw and capping between 850-700mb starts setting up in the fcst soundings. This should be a limiting factor for any significant precip along the next cold front that`ll be pushing through the area late Saturday night & Sunday morning. Both GFS and ECMWF show a jet streak moving across south Tx sometime between Mon afternoon and Tue afternoon possibly bringing another slight chance of precip...although fcst soundings across inland locations point more toward virga considering the dry sub cloud layer. Another reinforcing front (dry) is expected ~Tue which should keep temps slightly below normal going into the second half of Spring Break week followed by a gradual warm-up going into the weekend. 47 MARINE... High pressure should settle over the northern Gulf coast tonight into Thursday and this is expected to diminish winds. Winds will become NE tonight as the high moves east and will veer to the east on Thursday as the high moves further east. Southeast winds will develop late Thursday night as low pressure develops in the lee of the Rockies. A moderate to strong onshore flow is expected Friday night into Saturday which may require caution flags. The low moves NE on Saturday night and winds will briefly veer to the southwest. A cold front will cross the coastal waters Sunday morning. Strong offshore winds are expected to develop in the wake of the front and caution/advisory is likely Sunday night into Monday. Tides were about 0.5-1.0 feet below MLLW in upper portions of the Houston Ship channel and Galveston bay. Tides have since recovered going into high tide and with winds decreasing. Tides get a boost with the strong onshore flow Thursday night into Friday. Tide levels may rise a foot or so above normal but should only rise to 2.5 to 2.7 feet. We may need to watch for low water conditions behind the front on Sunday into Monday. 39 && .PRELIMINARY POINT TEMPS/POPS...
