Area forecast discussion, Jun 7, 3:19 PM CDT, 1 hour 19 minutes before
Area Forecast Discussion National Weather Service Lubbock TX 319 PM CDT Thu Jun 7 2018 .DISCUSSION... An overnight MCS across Oklahoma has continued to propagate through the day extending and reinforcing existing outflow boundaries well back to the west across the southern Texas Panhandle, South Plains and northern Rolling Plains. Warm temperatures aloft, in the upper teens C at H7, held off strong storms until now. We expect increased coverage of showers and storms as we head through the evening hours, mostly from the Caprock escarpment eastward into the Rolling Plains where a more unstable airmass is in place. Though, similar to what we've seen the past few days, we could see some strong storms develop as far back as the I27 corridor. Some of these thunderstorms may eventually produce strong or even severe wind gusts up to 70 mph and hail up to two inches, given their high bases. Overnight convection will continue southeast out of our area while gradually eroding during the overnight hours. Tomorrow will unfold similar to today as the center of the upper level ridge is draped across West Texas and eastern New Mexico. But with lee surface pressure falls to the north and a series of weak shortwaves in the upper level flow we'll see more conditional instability. In fact, similar evolution of ridging and weak instability aloft with above normal temperatures that gradually moderate back toward more seasonal levels by the middle of next week. Rain chances late Friday into Saturday seem to be dwindling somewhat as the upper level Pacific trough shifts eastward around the persistent ridging over the Central and South Plains. Surface winds will eventually become more southwesterly which will dampen rain chances. Guidance keeps afternoon dewpoints steadily in the upper 40s/lower 50s across our northwest zones to upper 50s/low 60s through across our southeast zones. With no drastic pattern change indicated in operational guidance we'll like continue to see numerous days beyond today and tomorrow, with spotty convection, especially as we head into next week. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 55
