Area Forecast Discussion National Weather Service Houston/Galveston TX Issued by National Weather Service Lake Charles LA 1230 PM CDT Thu Sep 14 2023 ...New AVIATION... .UPDATE... Issued at 1008 AM CDT Thu Sep 14 2023 No changes to the forecast at this time. Latest upper air sounding from over in KLCH and down in KCRP, along with LAPS analysis shows good moisture profile across the region with PWAT values near or above 2 inches. A short wave moving out of central Texas will work with the moisture to produce scattered showers and thunderstorms through the afternoon hours. Main concerns with the storms will be cloud to ground lightning and some brief heavy downpours. Rua/WFOLCH && .SHORT TERM... (Today through Friday Night) Issued at 306 AM CDT Thu Sep 14 2023 Shortwave embedded in the zonal flow aloft is making its way toward the Hill Country early this morning. Look for this feature to bring an increase in shra/tstm coverage across our region as it treks closer and into Southeast Texas as we head through the morning into mid-late afternoon hours. Similar to yesterday, overall forcing/dynamics aren't that impressive, though cannot rule out a isolated pulse stronger-sever cell or two. Brief strong winds would be the issue if/where this occurs. Considering the resident 2.2" PW's in place, think that localized heavy downpours are a fairly decent possibility. With the dry ground in place, rains are very much welcomed and it should be able to absorb precipitation without any widespread issues. What we'll be looking at is the rainfall rates themselves...and moreso over urbanized locations where rates at or above 2"+/hour could pose some minor, and localized, street flooding. Overall, guidance varies on amounts and hotspots, but would anticipate average 0.5-1.5" amounts. Yesterday, a cell near the Texas City area put down some 2-4" totals...and that would probably be a reasonable higher end estimate today where the stronger cells pass through and/or mesoscale interactions occur. Think we'll probably see precip taper down heading into the late afternoon and evening hours. We'll then turn our attention upstream late tonight and Friday for additional hard-to-time disturbances as they make their way toward and/or into the area and bring additional chances for precipitation. Models remain a mixed bag in regards to timing and finer details. As such, overall confidence is somewhat low (other than knowing decent shots of rain are favorable in this type pattern). 47 && .LONG TERM... (Saturday through Wednesday) Issued at 306 AM CDT Thu Sep 14 2023 Additional rain chances will arrive as we head into the weekend with the weakly defined boundary remaining in place over the area through Sunday. Shower and thunderstorm development will be further aided on Saturday and Sunday by the approach of a midlevel shortwave embedded within the dominant longwave trough/closed low over the northern central CONUS. With relatively abundant moisture remaining in place (PWs of up to 2 in), there should be fairly widespread convective development throughout the course of the weekend with most locations carrying 40-60% rain chances on Saturday and 30-40% rain chances on Sunday. Precipitation, along with widespread cloud cover, should work to keep temperatures in the upper 80s to lower 90s while lows will settle into the upper 60s to mid 70s. As the weak boundary pushes offshore on Sunday, there will be a brief shift to northerly winds that should allow some drier air to filter into the area. With surface dew points being largely driven down into the 60s as a result, conditions should feel a bit more pleasant heading into the beginning of next week. A broad midlevel ridge will gradually build to our SW over the course of next week, resulting in reduced but not completely eliminated rainfall chances as surface winds shift back to an onshore regime and surface moisture increases once again. That being said, most storm development will be tied to diurnal activity and daily rainfall chances currently range in the 20-30% range along the coast and lower further inland. Increasing midlevel heights and a return of SE winds will result in a slight increase in high temperatures with most locations seeing daily highs return to the mid 90s and overnight lows in the mid to upper 70s. Cady && .AVIATION... (18Z TAF Issuance) Issued at 1224 PM CDT Thu Sep 14 2023 An upper level disturbance and moist airmass will work together the bring about scattered showers and thunderstorms this afternoon affecting the terminals. Went with tempo groups for all terminals during mainly the 14/18z-22z time period. Gusty winds along with visibility restrictions and ceilings lowering to the MVFR/IFR levels. Activity is expected to end by sunset as the upper level disturbance moves off to the east and daytime heating ends. During the night should be mainly quiet with the exception of spots dealing with low clouds and patchy fog late tonight into early Friday morning. Rua/WFOLCH && .MARINE... Issued at 306 AM CDT Thu Sep 14 2023 Scattered showers and storms will continue to impact the bays and coastal waters for the remainder of the week and into the weekend, with some storms potentially producing strong gusts at times. Wind speeds will generally remain below caution thresholds outside of any brief strong gusts associated with thunderstorm activity. As the weak boundary overhead pushes offshore on Sunday, there will be a brief shift to offshore winds before a southeast flow re- develops heading into the beginning of next week.
