.AVIATION /20Z SATURDAY THROUGH THURSDAY/... Through 18Z Sunday...A very challenging aviation fcst for the next 6 to 12 hours with changeable conditions anticipated. For example SLK went from LIFR cigs to VFR in the past 10 minutes, so expect bouncing cigs/vis conditions at many of our sites this aftn into the evening hours. Highest probability of IFR conditions wl be at Rutland associated with block northerly flow down the Champlain Valley, with intervals of IFR cigs likely at SLK/MPV and BTV thru this aftn with mostly a mix of VFR/MVFR at MSS/PBG and EFK. As additional rain redevelops toward midnight tonight, along with light and variable winds, expect widespread IFR cigs with potential for LIFR cigs at RUT/SLK and MPV. These conditions should prevail thru 12z, before slowly lifting on Sunday to a mix of MVFR/IFR. Given the clouds/precip, thinking fog is unlikely attm, but some reduction in vis btwn 1-3SM is possible in -ra/mist overnight. Outlook... Sunday Night: Mainly VFR, with local MVFR possible. Chance SHRA. Monday: Mainly VFR, with local MVFR possible. Chance SHRA. Monday Night: Mainly VFR, with areas MVFR possible. Chance SHRA. Tuesday: Mainly VFR, with local IFR possible. Likely SHRA.
