Area Forecast Discussion National Weather Service Corpus Christi TX 114 PM CDT Mon Sep 25 2017 .DISCUSSION... Update for 18Z aviation cycle. && .AVIATION... Today...VFR. Some heavier showers and isolated thunderstorms will continue across the region this afternoon and evening. Brief reduction to MVFR/IFR possible with wind gusts upward of 25 knots. Otherwise no other impacts to the terminals. Medium to high confidence. Tonight...VFR/MVFR. Continued shower/storm activity across the west is expected while some streamer storms develop just off the coast and move inland during the mid-morning hours. Brief lower restrictions possible within the storms. Medium confidence. Tuesday...VFR. Expecting more showers and storms across the region but may hold off until after the current TAF cycle. Conditions generally look like a carbon copy of today with a bit more activity across the west than there currently is. Medium to high confidence. && .PREVIOUS DISCUSSION... /Issued 1143 AM CDT Mon Sep 25 2017/ DISCUSSION... Seeing some better coverage of showers across the Coastal Bend into the Coastal Plains near Victoria. Have increased PoPs a bit to account for this and expected activity through the evening hours. Seabreeze will continue to move inland and provide some better lift for showers towards the Brush Country later this afternoon. Have been watching an area of activity across part of the SdB mountains track towards the northeast. This may send an outflow towards the Rio Grande Plains later today helping to combine with the seabreeze for even more activity. Tried to show a general trend in the hourly temperatures to account for the rain activity, so they were lowered where the higher PoPs are in place. Otherwise the forecast is in good shape. PREVIOUS DISCUSSION... /Issued 639 AM CDT Mon Sep 25 2017/ DISCUSSION...See Aviation section for 12Z TAFs. AVIATION...GOES 16 channel difference for low clouds/fog indicated generally scattered low clouds over Coastal Bend this morning with some areas over the Brush Country showing broken clouds with MVFR ceilings. Sufficient moisture and steep low level lapse rates had led to isolated streamer showers over the coastal plains this morning. The activity will become more scattered after some heating and drift inland with the sea breeze through the afternoon. Showers and thunderstorms will provide MVFR ceilings/vsbys. Weak upper level disturbance moving out of northeast Mexico late this afternoon into evening should lead to scattered convection moving into the LRD area in the evening and early overnight period. Will show MVFR ceilings and vsbys with the convection. Coastal convergence zone will lead to redevelopment of coastal showers over the southern Coastal Bend that will affect CRP/ALI areas. MVFR ceilings expected to become prevalent over the coastal plains by 08Z Tuesday. PREVIOUS DISCUSSION... /Issued 437 AM CDT Mon Sep 25 2017/ SHORT TERM (Today through Tuesday)... The mid to upper level ridge axis over the region will translate eastward into the western Gulf of Mexico through Tuesday. Although GOES 16 image of precipitable water shows a region of drier air over the upper Texas coast making its way into the northeast part of the forecast area, higher moisture remains along the lower Texas coast up to the Coastal Bend with PWAT values from 1.8-1.9 inches. The NAM may have a better handle on how steep the low level lapse rates are over the coastal waters into the Coastal Bend this morning compared to the GFS/RAP. KCRP radar loop has shown a steady stream of isolated showers into the Coastal Bend over the past couple of hours. Expect with a little bit of heating, the coverage of convection will become scattered this morning from the coastal plains into the eastern Brush Country. Low level convergence zone will move inland with the sea breeze boundary this afternoon. Image of precipitable water showed the deeper moisture axis along the Rio Grande with PWAT values around 2 inches. Will show slightly better chance for convection over the Brush Country this afternoon. With the ridge axis moving east by tonight, a short wave trough will move out of Mexico, from Coahuila into the northern Brush Country up to the Hill Country by 12Z Tuesday. The upper level flow will be weakly diffluent while the low level flow will gradually strengthen from the southeast during the overnight hours. Will show PoPs of 40-60 percent over the Brush Country for tonight. After dry period this evening along the coast, low level convergence axis will strengthen overnight and expect scattered convection to develop over the Coastal Bend. Will increase PoPs back to chance category for overnight. NAM/GFS/ECMWF models show the short wave trough moving across the region on Tuesday. Deep moisture will be in place over South Texas on Tuesday with PWAT values above 2 inches along the coast to near 2.4 inches over the western Brush Country. PoPs will be tapered from 40 percent at the coast to likely at 60 percent over the Brush Country. LONG TERM (Tuesday night through Sunday)... Forecast remains favorable for a wet mid week especially across the western half of the CWA (Rio Grande Plains and Brush Country). The upper level closed low which will form over the southwest states will slowly progress east northeastward into the Four Corners region during the mid week. Deep Pacific moisture will be drawn into the region, with precipitable water values climbing above normal (well above 2 inches). With the position of this upper level disturbance the heaviest rainfall will remain to the north and west of the region over the up stream Rio Grande river basin, and may bring some rises along the river. Locally though, still anticipate moderate to locally heavy rainfall will be possible with widespread showers and thunderstorms across the western zones, and more scattered convection to the east Tuesday night into Wednesday. Rain chances will slowly decrease Thursday into Friday as the closed low opens and lifts the the northeast. As the disturbance lifts to the northeast a cold front will move south across the state and into South Texas. The cold front is forecast to move into the region Friday, though seeing some differences in the models between the strength of the front and continued rain chances across the region late into the weekend. Anticipate more of a northeast shift to the winds and slight lowering of temperatures late in the week into early next week. Lower dewpoints and less humid conditions late in the period will also bring more seasonable conditions to the region. High temperatures will gradually go from the upper 80s/lower 90s to the mid/upper 80s, and lows from the lower 70s falling to the lower/mid 60s. && .PRELIMINARY POINT TEMPS/POPS...
