Area Forecast Discussion National Weather Service Amarillo TX 1235 AM CDT Mon Jul 13 2020 .AVIATION...06Z TAFs. VFR conditions expected through the period at all TAF sites. Thunder, currently near GUY as of 0530z, should be far enough east of the terminal for no impact, so have left it out of the TAF. Main issue in the short term is wind direction, with the showers and isolated storms sliding eastward across the Panhandles leading to temporary shifts to northwesterly winds at all TAF sites. Expect winds to cease being northwesterly within the next couple hours and become light and variable overnight. For tomorrow, expect a return to southerly and southwesterly winds at all sites by the mid morning hours. Attention then turns to another potential round of showers and thunderstorms approaching from the west, mainly after 00z. At this time, probability of occurrence is too low for a mention with 2 to 3 TAF cycles before potential onset of thunder. Ferguson && .PREV DISCUSSION... /Issued 435 PM CDT Sun Jul 12 2020/ DISCUSSION... For this afternoon and tonight, a fairly well defined upper level shortwave trof is progged by short range models to rotate southeastward across the southern high plains around the northeast periphery of the upper level ridge of high pressure centered across southern AZ and southern NM. Expect showers and tstms to initially develop over the higher terrain of northeast NM and southeast CO, then track southeast across the fcst area late this afternoon through tonight. Some storms will have the potential to become severe late this afternoon and evening, with large hail and damaging winds the primary hazards. In addition, an isolated landspout tornado is not out of the question, especially across the western OK Panhandle and the northwest Texas Panhandle. The greatest threat for severe storms is expected to be across the northwest zones up against the higher terrain in sern CO and northeast NM. Overall highest pops were placed in the northwest zones, with a gradient down to slight chc values in the southeast Texas Panhandle. The upper level ridge of high pressure is progged to meander around the area through most of this week. The steering flow supports showers and storms that initially form over sern CO and ern NM to move east or east southeast across at least parts of the area mainly during the evening hours Monday through Wednesday night. NBM pops through Wednesday night appear to have caught on to this upper level flow pattern and were utilized, with NBM slight chc values edged just a tad further east into the northwest and far western zones Thursday evening, Friday evening, and Saturday evening given the medium range model progs. Above normal temperatures will continue during the next 7 days, with Heat Advisories becoming necessary for at least parts of the forecast area Monday and Tuesday. 02 && .AMA Watches/Warnings/Advisories...
