Area Forecast Discussion National Weather Service Saint Louis MO 350 AM CDT Sat Oct 16 2021

SHORT TERM. (Through Late Sunday Afternoon) Issued at 244 AM CDT Sat Oct 16 2021

An upper level trough extends from eastern WI south-southwest into AR. A large surface ridge was centered over western KS. Cool and dry conditions can be expected today and tonight with northwesterly upper level flow, and as the surface ridge continues to build into MO. Despite full sunshine today high temperatures will be about 5 degrees below normal for the middle of October. The coldest temperatures of the Fall Season so far can be expected tonight due to good radiational cooling with a clear sky, light surface wind, and surface dew points only in the 30s. Lows tonight will be in the upper 30s to lower 40s. Could not rule out isolated light frost late tonight/early Sunday morning in the normally colder, low lying areas, mainly in parts of central and southeast MO near the surface ridge axis. Will see the start of a warming trend Sunday afternoon due to rising upper level heights as an upper level ridge in the Plains approaches MO, and as the surface wind begins to back around to a southwest direction as the surface ridge shifts southeast of our area.

GKS

LONG TERM. (Sunday Night through Friday) Issued at 244 AM CDT Sat Oct 16 2021

Warmer temperatures can be expected Monday through Wednesday with upper level ridging over the region combined with persistent southerly winds. High temperatures will be about 5 to 10 degrees above normal. The chance of showers will return Wednesday and Wednesday night as an upper level trough/low moves eastward through the Northern Plains and into the Great Lakes region and sends a cold front southeastward through our forecast area Wednesday afternoon and night. At least scattered showers and a few storms can be expected along and just ahead of this front. The models are fairly consistent, although there is slight timing differences in the progression of the upper level trough and associated cold front. Cooler temperatures can be expected Thursday through Friday after passage of the cold front, although there is a growing spread in the model temperature guidance for the end of the work week. The operational GFS appears to be an outlier, bringing a strong surface ridge into the region from the Northern Plains along with much colder air by Friday and Friday night. Followed the more moderate NBM guidance with highs on Friday only about 5 degrees below normal.

GKS

AVIATION. (For the 06z TAFs through 06z Saturday Night) Issued at 1046 PM CDT Fri Oct 15 2021

All terminals are clear of precipitation through the forecast period. The departing system to the east and building surface high from the southwest will result in quieter, northwesterly flow. The only impact to mention will be gusty winds during the day Saturday. VFR conditions will extend through entirety of the forecast period.
