NWS Amarillo, TX wrote its last area forecast discussion before the first event at Jun 26, 11:23 AM CST, 1 hour 17 minutes earlier.
Area Forecast Discussion National Weather Service Amarillo TX 1223 PM CDT SUN JUN 26 2016 .Aviation... 18Z TAF Cycle The remnants of a frontal boundary across the southern Texas Panhandle today along with a closed upper low over southwest Texas lifting north will help to trigger scattered convection mainly across the Texas Panhandle this afternoon into this evening. The Amarillo and possibly the Dalhart TAF sites will likely be affected by the convection between 18Z today and 03Z Monday. Light mostly southwest to southeast winds 10 knots or less are expected at all three TAF sites this afternoon and then becoming light and variable after 06Z to 08Z Monday. VFR conditions will prevail at all three TAF sites except in and near the convection where MVFR conditions are expected. Schneider && .Prev Discussion... /Issued 628 AM CDT SUN JUN 26 2016/ Aviation... The fog at DHT with MVFR conditions should be short lived, so have not inserted it into this forecast. Otherwise, VFR conditions should prevail outside of thunderstorms at all sites through this forecast. The best chance of thunderstorms will be this evening, so have inserted a PROB30 at all sites during this timeframe. Winds will be light and variable for the first part of the forecast, then they should become southeast, but they should remain around 10 knots or less. Prev Discussion... /Issued 347 AM CDT SUN JUN 26 2016/ Discussion... Thunderstorms formed last evening in a fairly narrow corridor near a surface trough that extended from northeast New Mexico into Kansas. This boundary probably had some tie to northern Plains shortwave baroclinicity along the boundary was weak or non-existent in analysis earlier in the day prior to convective development. Thunderstorms became fairly numerous during the evening before diminishing later in the night. Cold pool/mesohigh and outflow has masked this boundary making it diffuse and recovery from this tomorrow is in question. Models vary in surface pressure pattern depiction tomorrow with most not showing a synoptic scale boundary and several showing an increasingly diffluent surface wind field during the afternoon. For this reason, have limited precipitation probabilities to the high end of chance category during the afternoon and evening. Despite lack of a notable low level convergent signal in short term guidance, thermodynamics support convective development with moist low-levels in an uncapped environment that will become increasingly unstable as heating commences. Weak forcing for ascent may be present on the northern edge of an upper low that will drift slowly east-northeast into central Texas tomorrow afternoon. Highest precipitation probabilities were aligned with model placement of strongest pressure gradient on 1.5 PVU surface, but trends will be monitored and adjustments to this will be made based on observational data through the day. Relatively weak mid level lapse rates should limit MLCAPE to around 1,000-1,500 J/kg this afternoon. Winds aloft continue to be weak with 0-6 km shear around or under 10 knots and cloud layer shear around 15 knots at best. This is insufficient for sustained/organized updrafts and will limit the severe potential to isolated brief marginally severe gusts. Slow storm movement and deep moisture (model projected PWAT around or slightly over 1.5") will support locally heavy rainfall amounts. We saw this today with 1.68 inches measured at the Eva mesosnet. Similar thermodynamics Monday along with subtle height falls by evening from deepening Great Lakes trough should be enough to justify high chance probabilities once again. There is some question on placement and degree of amplification of western of southwestern CONUS trough though and this could ultimately be further east/stronger leading to reduced chances. The ridge should build in substantially enough Tuesday to limit chances to slight/low across most of the area. Mid-upper level flow will increase and veer to northwesterly by late Tuesday. This persists through at least the end of the week with periodic shortwaves embedded within the flow affecting the area. When and exactly where these enhance convective development is uncertain, although models are in agreement on a fairly pronounced shortwave passing by Wednesday, possibly resulting in an MCS that may affect the northeastern portion of the forecast area Wednesday evening. We have confined highest probabilities then to those areas. Late Thursday through Friday evening may be when the highest chances for precipitation exist. Models shift or reorient the upper ridge further south which results in west-northwesterly flow over our area and a series of perturbations pass through. These along with mountain diurnal convection and overall faster mid level flow suggest an organized thunderstorm complex or two may pass through during that period, especially across the northern half of the area. A weak cold front may move southward into the area then too bringing slightly cooler temperatures late in the week and into the weekend. BRB && .AMA Watches/Warnings/Advisories... TX...NONE.
