System headed our way, with mid clouds racing past us now associated with upper level disturbance that will keep moving on past us. More significant factor is the cold front headed toward the area that will bring some low level moisture will it, and will offer the potential for MVFR ceilings, especially north of KTYS. For now only have ceilings at KTRI, with only SCT low clouds at KTYS and briefly at KCHA. Looking at SREF ceilings, quite a few members clustering around ceiling of 015 at KTRI, so could be lower than the OVC025 in this TAF, but checking upstream, not seeing any ceilings below 020. As drier air pushes into the area during the day on Thursday as well as surface heating and deeper mixing, cloud heights should rise.
