The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS St. Louis, MO wrote its last area forecast discussion before the first event at Dec 31, 11:45 PM CST, 15 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 1145 PM CST THU DEC 31 2015 .SHORT TERM: (Through Late Tonight) Issued at 1258 PM CST Thu Dec 31 2015 Latest satellite data suggests the clouds may finally clear out of the area this evening, before another batch moves in late tonight. Some diurnal CU has developed on the NW side of the clearing edge, but these clouds shud dissipate with sunset. The original edge of the clouds is expected to be close to leaving the CWA around 00z. Mixing is expected to persist thru the night, which shud help keep temps slightly warmer despite the clear sky. Tilly .LONG TERM: (Friday through Next Thursday) Issued at 1258 PM CST Thu Dec 31 2015 The more zonal pattern breaks way to NW flow this weekend. This will allow a number of s/ws to pass thru the area along with reinforcing cdfnts. Each cdfnt is not expected to cool temps much as some warming ahead of the fnt is expected as well. A deeper trof expected early Mon will help pull a larger arctic sfc ridge into the area which will bring cooler temps with it. This will be offset somewhat with upper level ridge building into the region which will help keep the area dry. The sfc ridge is expected to pull ewd by Wed with sly flow returning to the area. Both the GFS/ECMWF suggest the next chance for precip arriving late next week. However, given the upper level setup, have low confidence in the timing. Believe most precip will hold off more into the weekend. Tilly && .AVIATION: (For the 06z TAFs through 06z Friday Night) Issued at 1145 PM CST Thu Dec 31 2015 First batch of low end VFR clouds (3-4kft) should exit the STL metro area next few hours. Another, and larger, area of primarily low end VFR cigs are currently working its way se across IA, and it appears that the southwest fringe of this cloud deck will be clipping areas along the Mississippi River during the early morning hours. Once this cloudiness rotates out of the area no later than mid morning, mainly clear skies are expected for the rest of the TAF period. Specifics for KSTL: Scattered to briefly broken clouds 3-5kft through mid morning, with generally clear skies during the afternoon and into the early evening hours.
