NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Sep 21, 11:28 AM CST, 1 minute earlier.
Area Forecast Discussion National Weather Service Houston/Galveston TX 1228 PM CDT Thu Sep 21 2017 .AVIATION... Widespread showers and thunderstorms will continue throughout the afternoon before eventually dissipating after sunset. Vis under 2SM are possible in the heavier storms along with gusts to 20-25kt. Some fog and low cigs will be possible again tonight, primarily north of KIAH. Some patchy dense fog will be possible, particularly in areas that receive rain today. Some showers and storms will be possible again tomorrow afternoon, but coverage should be much more isolated than today. 11 && .PREV DISCUSSION... /ISSUED 1000 AM CDT Thu Sep 21 2017/ DISCUSSION... Just did some very minor changes to the grids on the morning update. Shower and thunderstorm coverage has been increasing across the area this morning, and expect this trend to continue for the remaining morning and afternoon hours. So far, everything is moving along at a pretty good clip. We'll be watching for any training that sets up which could lead to some possible localized flooding issues. 42 CLIMATE... Yesterday's rains at IAH brought their yearly total up to 71.78 inches. Only 1.09 inches of rain is needed through the end of the year to make 2017 the wettest year on record for the City of Houston (first place is currently 72.86 inches set in 1900). 42 PREV DISCUSSION... /ISSUED 337 AM CDT Thu Sep 21 2017/ DISCUSSION... The pattern over Southeast Texas early this morning consisted of an upper low pressure trough that extended from the Mid Atlantic coast through Louisiana into our area. An upper level high pressure ridge was across North and Central Texas and bordered the northern and western portions of the forecast area. An abundance of moisture was present south of the Interstate 10 but mainly off of the coast into South Texas. Models show that this moist airmass will push northward this morning. Given the unstable airmass do expect isolated showers currently occurring along and off of the coast to spread inland and become more widespread this morning and afternoon. Model forecast soundings show the potential for locally heavy rainfall given that PWs reach 2.0 to 2.1 inches and K-indices reach to between 34 and 36. There is also the potential for isolated strong storms as CAPE values will reach to between 2800 and 3300 during the mid and late afternoon period. The shower and thunderstorm coverage should decrease on Friday and Saturday as the upper level high pressure ridge builds overhead from the west. A combination of an approaching upper trough and a weakening of the ridge will lead to a more unstable airmass beginning on Sunday. This in turn will lead to increasing rain chances through the first half of the week. 40 MARINE... Light to moderate southeast winds and seas around 3 feet are forecast to persist along the Upper Texas Coast through at least the next week. Scattered showers and a few thunderstorms will be possible this morning through today as higher moisture moves inland from the Gulf. Showers and a few thunderstorms will be possible each day going into next week with the best chances in the morning for the coastal areas. Tide levels will likely be about a half foot above normal through the rest of the week with maybe a slight increase to 1 foot above normal over the weekend.
