Area forecast discussion, Jun 12, 6:30 PM CDT, 1 hour 29 minutes before
Area Forecast Discussion National Weather Service Lubbock TX 630 PM CDT Mon Jun 12 2017 .AVIATION... Thunderstorm activity near KPVW may hold together trough 03Z-05Z as it makes its way toward KCDS. Further south toward KLBB, a lower risk of TSTMs will exist until about 02Z. This activity should be fairly short lived at any given terminal. VFR to persist outside of convection. && .PREV DISCUSSION... /issued 302 PM CDT Mon Jun 12 2017/ DISCUSSION... We will see our first significant thunderstorm chances in a while over the next couple of days. Southwest flow aloft has increased today and will continue to do so through Tuesday. This was in response to a deep upper level low currently in the Great Basin. This low will eject out of the Great Basin into the northern Rockies and then the northern Plains tomorrow. Dryline convergence will continue to sharpen by late this afternoon centering around the I-27 corridor. A minor secondary dryline will also sharpen in eastern New Mexico but is not expected to have much of an impact on convective chances. there is still some minor capping this afternoon which prevented convection the past several days. However, this capping is expected to become weak enough to allow convection to develop. Surface dew points in the lower 60s have allowed mixed layer instabilities to climb to around 2000 J/kg already and could go slightly higher in the next few hours. Deep layer shear has improved from yesterday with values on the order of 25-30kt today. Although a cu field is completely absent at the moment, convection is still expected to develop as all hi-res models depict. Initiation time is anticipated to be around 23Z or so. Even better chances for convection will come on Tuesday as the flow aloft further increases. Instability is progged to be slightly less than today with only a very weak cap by the afternoon again with an earlier initiation time. We will begin to see rising heights on Wednesday with a strengthening ridge to the south of the region. The dryline will be sticking around the area but this ridge will fight the dryline convergence in creating convection on Wednesday and Thursday afternoons. This ridge will also lead to very warm temperatures with daytime highs likely eclipsing 100 degrees possibly for a few days peaking Friday-Saturday. Since low level moisture will also be around, morning lows will only drop into the lower 70s. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 99/99/26
