WHAT HAS CHANGED

Expired the frost advisory for this morning.

KEY MESSAGES

1) A seasonably cool airmass will be in place across the region through Monday before warmer temperatures return by mid week.

DISCUSSION

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.
