Area Forecast Discussion
National Weather Service Paducah KY
1120 PM CST Mon Mar 6 2017

.UPDATE...
Issued at 1120 PM CST Mon Mar 6 2017

Updated for 06Z aviation forecast discussion.

&&

.SHORT TERM...(Tonight through Wednesday night)
Issued at 252 PM CST Mon Mar 6 2017

Strong/deepening transport of moist air is ongoing over the Quad
State, well out ahead of a developing cold front, as evidenced by a
surge of 60s surface dew points already nosing into SEMO. Gridded
time/height cross sections show some dry air still between about 850-
600 mb, but fully saturating by late evening into the overnight
hours. Soundings reveal PW's on the order of 1.3", or near the 99th
percentile for this time of year.

As the column moistens, it also destabilizes. We don't see it doing
so enough to support prevalent thunder mention til after 00z,
although this is marginal for the far western Ozark counties in the
21z-00z time frame. However, by midnight, we see 0-1KM MUCapes
approach 4 digits in the western Ozarks, and maybe reach the 500-
1000 J/KG range perhaps across the remainder of SEMO. With the cold
front extending northeast to southwest across the Show Me State at
06z, we'll see pre frontal convection/including thunder start to
develop best in our (western) counties in the 03z-06z time frame. A
Slight Risk of Severe will exist (SWODY1) for damaging winds as wind
fields/shear deepen upon the front's approach, with an Enhanced Risk
primarily (just) west of the CWA within the heart of the instability
axis/peak wind shear. Surface gradient winds will likewise be
increasing thru the teens/perhaps into the 20s mph, and may include
gusts into the 30s mph, but should stop shy of advisory criteria.

That then translates on eastward across the FA, as the front moves
in, and bears down on the Ohio river by tmrw morning. As it does,
the instability fields are sorta pinched off to the south/west, but
bulk shear still exists and should maintain enough to support the
mention of thunder, including the SLGT risk of svr, at least for
about the western half of the FA for the first half of the night.
Even so, it'll be increasingly transitioning to a heavy rain event
after midnight, particularly from 09z-15z. Anticipate good soaking
rains given high spring-like seasonal PW's and still good forcing
even after max instability fields start to diminish.

The front is a little slower than previous runs, so we carry the
heavy rain along it thru our southeast counties thru tmrw morning.
Afternoon hours is when we see the drier air start working further
down the column in more earnest, and pcpn shutting off more
completely as the front departs/finally fully exits to the east.

.LONG TERM...(Thursday through Monday)
Issued at 252 PM CST Mon Mar 6 2017

Confidence in the long term portion of this forecast is low. The
12Z model suite brings a stream of 3 storm systems through our
region from Thursday through next Monday in a relatively fast west
northwesterly flow aloft. Each of these systems start out as jet
energy over the northern Rockies, that amplifies to some extent
over the Plains/MS Valley. The models have not locked in very
well, which is to be expected with this type of pattern.

A 1040+ surface high will attempt to spill down out of the
northern Plains Thursday, and a surface wave will develop along
the leading edge over Missouri by 00Z Friday. The surface wave
will move eastward over or near our area Thursday night. Elevated
instability is generated in the models, so will keep a chance of
thunderstorms in the forecast.

Friday should be dry, but temperatures are iffy with the Arctic
high trying to spill into our region. The models have trended
cooler with the system arriving early Saturday morning, and that
has led to an introduction of some snow mention in the far north
early Saturday morning. If the 12Z models are correct, our
temperature forecast is likely too warm, and there may be more of
a concern for measurable snow Saturday. Will have to wait and see
what the models do with that cold surface high before getting too
excited about a brief bout of winter. On the flip side, if that
cold air does not make it to our area, thunderstorms may be more
of a concern than wintry weather.

The final system will move into the area on Monday. In the
progressive flow pattern, the surface high will push east of the
area allowing for south winds and nice warm, moist advection ahead
of/into this system. This should be an all liquid event, but there
is a brief mention of snow with the rain in the north early
Monday morning. The precipitation is not likely to begin until
later in the morning, so no issues expected at this time. Of
course if we are colder for the Saturday system and actually get
some snow, that could have an impact on the Monday system.

Lots to watch for in this is active week of weather. Stay tuned.

.AVIATION...
Issued at 1120 PM CST Mon Mar 6 2017

Main challenge with the 06z TAF continues to be non convective
winds and timing of main convective line of thunderstorms. Kept
non-thunderstorm wind gusts in the 30-40 kt range but they could
be even higher at times, ahead of the passage of the convective
line. Will keep wind shear outside of the main convective line as
well. Main convective line will pass through during the overnight
hours with rapidly improving conditions during the morning. Could
see strong wind gusts within the convective line as well. Winds
shift behind the line during the early morning hours to NW and
become less gusty.

304 PM CST Mon Mar 6 2017

This Hazardous Weather Outlook is for portions of southern
Illinois, southwest Indiana, western Kentucky, and southeast
Missouri.

.DAY ONE...Tonight

A slight risk of severe storms is forecast for mainly the western
half of the region, with a marginal risk of severe storms for much
of the eastern half. An enhanced risk of severe storms will focus
just to the west of our region, in the Missouri Ozarks.

The primary severe weather hazard with storms will be damaging
winds, with large hail and isolated tornadoes a possibility. The
storm threat will occur along and ahead of an approaching cold
front, and will last from late this evening into the overnight
hours. As the front moves east through the area, the severe weather
threat will gradually transition to a heavy rain threat, which may
cause some localized flooding issues.

Gusty winds outside of storm activity will also pose a heightened
hazard, with gusts into the 30s mph tonight a possibility. Average
winds may reach into the 20s mph. These winds will blow from south
to north, and may cause issues for vehicular traffic, especially
high profile units, on area roadways.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

The cold front will complete its eastward movement and ultimate
departure across our eastern third of the region Tuesday. A marginal
risk of storms reaching severe limits cannot be ruled out. Likewise,
heavy rain may still impact this area, mainly along and east of the
Lakes and across the Pennyrile region of western Kentucky, Tuesday
morning. Localized flood issues may occur. If a severe storm occurs,
damaging winds will be the primary anticipated hazard. Strong
surface winds into the 20s mph, with gusts into the 30s mph, will
also remain a hazard, even outside of storms, until the front's
final passage by early Tuesday afternoon.

A chance of thunderstorms is forecast for the entire area Thursday
night. Lightning and locally heavy rainfall will be the primary
concerns.

.SPOTTER INFORMATION STATEMENT...

Spotters throughout the region should be prepared for activation
late this evening through Tuesday morning.

...Occasional wind gusts between 35 and 50 mph likely ahead of
thunderstorms later tonight...

At 1030 pm CST, the current line of thunderstorms prompting
several warnings across Missouri stretches from the northeast
corner of Missouri to the southwest corner.

As showers continue to develop and move across the area through
midnight. wind gusts between 35 and 45 mph will be likely.

These strong wind gusts will continue to expand across Southern
Illinois, reaching across the Ohio and Wabash Rivers into
Southwest Indiana and West Kentucky between 11 pm and 1 am CST.

Wind gusts may even approach 50 mph over parts of Southern
Illinois and Southeast Missouri near or after midnight, along and
ahead of developing thunderstorms.

If you are traveling tonight, be prepared for gusty winds that may
cause issues for controlling your vehicle. This will be especially
problematic for tractor trailers, recreational vehicles, and other
high profile vehicles.

These winds may down branches and some trees weakened by storms
early last week. If these branches fall on power lines, this may
also cause some power outages.

Stay tuned to NOAA Weather radio, commercial television and
radio, as well as social media for the latest weather updates,
statements and warnings.
