          KEY MESSAGE 1)
          An upper level trough will shift east across the Great Lakes and
          Ohio Valley through Monday. With a cold airmass settling in across
          the region today, highs this afternoon will only range from the mid
          50s north to around 60 degrees in the south. Lows tonight will range
          from near 30 degrees in the north to the mid 30s south. Will
          therefore issue a Freeze Warning for about the northern half of our
          area and a Frost Advisory for the south. Temperatures will remain
          seasonably cold on Tuesday with afternoon highs mainly in the 50s.
          
          Mid level ridging will build into the region through mid week,
          resulting in a warming trend. Highs by Tuesday and Wednesday will be
          back into the 70s.
          
          &&
          
          .AVIATION /12Z SUNDAY THROUGH THURSDAY/...
          We will see a period of clear skies this morning. A weak embedded
          mid level short wave will move across the southern Great Lakes later
          today. This will lead to an increase in mid level clouds heading
          into the afternoon hours and it will be tough to rule out a few
          sprinkles or light rain showers, mainly along and to the north of the
          I-70 corridor. West winds will also increase later this morning and
          gust to around 25 knots or so through the afternoon. Skies will
          clear overnight along with a decreasing wind trend.
          
          OUTLOOK....MVFR conditions are possible on Wednesday.
