Discussion: 

Don't forget your hats and gloves for your morning commute to class! Winter is back after unseasonably warm temperatures this past weekend. Temperatures will stay in the mid-twenties for most of the period before a "warmup" brings temperatures to the mid-thirties on Wednesday.

Technical Discussion: 


The problem of the day and for the first part of the week are the frigid temperatures today and tomorrow. Wednesday could see a slight warm-up. While the GFS and NAM sfc maps were in agreement with the placement of the different systems around the country ultimately the GFS was chosen due to its better handling of moisture and temperatures. The NBM was also considered for temperature. 

The 250mb map showed the upper level jet placed along the Midwest as a trough pushes its way through the region. A jet streak will be centered on Missouri Tuesday morning until Wednesday afternoon. The 250mb map does not show any significant upper level divergence. At 500mb vorticity is weak and overall there is strong zonal flow.

 700mb level moisture will remain low through Wednesday for the CWA. Southern portions of Missouri have potential to see wintry precipitation. The 850mb shows strong CAA in the early this afternoon. 

At the surface Missouri is being dominated by a HPS moving east from Kansas  from which is keeping things quiet. The HPS will enter the CWA Tuesday evening and control the area for the remainder of the forecasting period. This keeps the CWA dry and cold for remainder of the forecast period. 

Temperatures will remain in the mid 20s for the highs and mid to upper teens for the lows. This is about 15 degrees below the average January temperatures for Missouri. Wednesday will bring a break to the cold temperatures with a high in the upper 30s. Today and tomorrow will remain cloudy before some sunshine Wednesday to welcome the warmer temperatures.
