NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 13, 2:33 PM CST, 2 hours 3 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 333 PM CDT Tue Jun 13 2017 .DISCUSSION... The forecast area finds itself between the semi-permanent sub- tropical upper ridge to our south and a pretty strong closed low over the northern Rockies. Mid and upper level southwesterly flow over the southern High Plains is helping the dryline mix eastward into the western part of the forecast area while east of the dryline healthy moisture exists indicated by surface dew point temperatures in the lower to middle 60s across the eastern half of the forecast area. This set up provides a good potential for large hail-producing thunderstorms through early to mid evening. Big CAPE will exist with the rich low level moisture while flow aloft will provide enough deep layer shear to get the strongest updrafts spinning. The previous forecast handles well with only some minor adjustments to the PoP and weather grids. The northern Rockies upper low will lift northeastward into the Prairie Provinces Wednesday, allowing the upper ridge to our south to expand northward. Increasing mid level temps will begin to quash thunderstorm chances with little low level focus and less upper level support than seen today and yesterday. Have lower precip chances slightly, limiting to slight chance range both Wednesday and Thursday. The ridge will amplify northward across the desert southwest during the weekend and expand eastward across Texas. This should effectively shut precip chances down. Of note is a weak cold front that is still progged into the forecast area Sunday before stalling. Ideally, this would serve as the focus for convective initiation. However, the ridge is looking too strong at this time. Regarding temperatures, model blend looks good for both lows and highs. Of note, is the blend came in warmer for daytime highs than MOS. Given the pattern and recent history this is preferred. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 07
