National Weather Service Shreveport LA 303 PM CST Thu Dec 14 2017 .DISCUSSION... Wv imagery this aftn shows entrenched upper ridge over the wrn CONUS and trof axis extending from Baja all the way ne into the Great Lakes region. Swwd extension of the trof tapping into Pacific moisture, transporting it newd into much of TX/LA. Nrn extent of the trof will progress ewd Friday and Saturday, leaving behind a large, cut-off low over wrn Mexico. Meanwhile, another disturbance will emerge and dive swd along the ern periphery of the upper ridge. This Will force the cut-off low to begin lifting newd Saturday towards our region. Top-down moistening of the column along with some rapid ll moisture return will result in shwrs/isold tstms developing and spreading newd into the ArkLaTex by Saturday evening. Good widespread averages near an inch to two inches look to be possible with this disturbance before it moves on Sunday morning. Upper flow will remain swly as the second disturbance becomes cut off over AZ. Developing low pressure along the TX Gulf Coast will provide some additional moisture as the disturbance moves ewd into the Srn Plains early next week. Some question as to the coverage of any associated convection, but have retained some conservative PoPs into the fcst for that timeframe. Mild and drier airmass will filter in in the wake of this disturbance as we move into the middle part of next work week under zonal flow aloft to take us to the end of the pd. /12/National Ag.
