.PREV DISCUSSION... (Issued 327 AM CST Mon Jan 27 2020)

SHORT TERM...

Today through Tuesday...Forecast Confidence is Medium...

Mostly quiet conditions are expected for today and tomorrow. The
only wrinkle in the forecast is a couple slight chances for
freezing drizzle and light snow early this morning and late
tonight. With low level moisture in place, a surface front moving
through early this morning may spark off areas of freezing
drizzle or light snow. Any precipitation is expected to end by
sunrise. Tonight another boundary, at 850mb, moves through between
midnight and 6am. This will be the best window for any freezing
drizzle or light snow and could cause some slick spots on roads.

LONG TERM...

Wednesday Night through Sunday night...Forecast Confidence High...

Relatively quiet and cloudy conditions will continue through the
rest of the workweek. Other than perhaps a stray flurry, Wednesday
and Thursday should be dry. Highs will be in the low to mid 30s,
with lows ranging from the upper teens to mid 20s. Winds will
generally be light and variable.

Somewhat better organized upper level flow will push into the area
Friday and Saturday. This will bring low chances for light rain or
snow. Upper level ridging will then move in for the remainder of
the weekend, with temps approaching 40 by Sunday. A few peaks of
sun will even be possible at times.

AVIATION(09Z TAFS)...

Any IFR ceilings will lift above 1,000 feet late this morning.
Still watching a slight chance for some light freezing drizzle
this morning. Any freezing drizzle would end by 12Z. MVFR ceilings
will continue into Tuesday morning. Watching for another round of
light freezing drizzle after 06Z tonight.

MARINE...

North to northwest winds continue and become lighter as we head
into the middle of the week. High pressure moving through southern
Canada will allow light winds and low wave heights to continue
through Friday.
