Area Forecast Discussion National Weather Service Houston/Galveston TX 1235 PM CDT Sun Apr 5 2020

AVIATION. LIFR/IFR ceilings are gradually becoming MVFR inland and SCT near the coast as some drier air filters into the area from the east. A mix of MVFR and VFR ceilings are expected this afternoon with NE to E winds. Uncertain as to how much lowering ceilings and/or visibilities we'll be seeing tonight as onshore flow and associated increase in moisture does not settle back into the area until the daytime hours tomorrow. For now, have most sites becoming MVFR during the overnight hours. With the onshore winds tomorrow, think we might stay MVFR for most of the day. Rain chances are currently too low to include mentioning in the TAFs. 42

PREV DISCUSSION. /ISSUED 412 AM CDT Sun Apr 5 2020/

SHORT TERM [Through Monday] . Cloudy, cool & foggy across the region early this morning. Northerly surface winds will gradually be veering to the east and southeast today-Mon as high pressure moves away from the area. Llvl moisture should be trapped under the inversion for a good portion of the day and cirrus will continue streaming overhead so mcldy conditions should prevail. Can't totally rule out some isolated sprinkles or a shower, but overall column moisture has diminished and don't see much upstream which should lead to much in the way of precip today. Deterministic and hires models have also backed off the rain chances for Monday. The sharper northward moving warm front previously depicted now appears to be just a gradual veering of the winds along with a less active sw flow aloft (which may or may not be the case). Lowered POPs down a touch from NBM suggestions, and dayshift may need to make further cuts across parts of the area if trends continue. 47

LONG TERM [Monday Night Through Sunday] . A gradual warming trend remains in the fcst as Gulf ridging edges northward into midweek. Higher PW's, daytime heating and possibly some impulses riding over the top of the ridge should be enough to trigger some isolated-scattered precip across inland areas into midweek.

Another shallow cold front will try to slowly sag into the region as we head into Thurs/Fri and bring our next shot of shra/tstms to the region. Upper pattern around that time is still a bit hazy as models struggle with (any) eastward progression of the upper trof currently digging southward along the west coast. 47

MARINE . While offshore winds have decreased overnight, seas have remained elevated As such. did extend the SCA for the offshore waters un- til later this morning Otherwise. not a lot of changes with the ongoing forecast of winds slowly shifting to the east this after- noon/tonight . then becoming more southeast by tomorrow (with the passage of the warm front inland). Intermittent periods of shower and thunderstorm activity are expected through much of the upcom- ing week along with a persistent light/moderate onshore flow. Long range models are hinting that the next cold front could move into the coastal waters late Thurs/early Fri. 41

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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