.SHORT TERM...(Tonight through Saturday night)
Issued at 252 PM CDT THU APR 10 2014

Latest surface analysis shows a cold front extending from the
central Great Lakes through central Illinois and central Missouri
and into western Oklahoma. Radar shows some light showers
developing along and especially behind the front. Models are in
good agreement positioning the front along the Ohio River into
portions of southeast Missouri by 12z Friday. Models show precip
making it to the Ohio River by 06z, spreading southeast by mid
morning Friday. Where models differ is QPF amounts, with GFS
showing the most significant amounts, and ECMWF the lightest. NAM
is the middle ground, and leaned toward the NAM for amounts. CAPE
values and LI`s still indicate we will see some thunderstorms,
especially during the day Friday, but away from thunderstorms
overall amounts should be two tenths of an inch or less. Also,
better chances and the more substantial QPF will be across our
eastern counties where more moisture will be available, so went
with good chance pops east, to low to slight chance west.

ECMWF shows a bit of QPF lingering in our far eastern counties
Friday evening, while GFS and NAM keep us dry. We already had some
low pops for showers in those areas for Friday evening, so I
backed off some on both pops and coverage.

For Saturday, both NAM and ECMWF show a smattering of light QPF
across our area, while GFS and GEM keep us dry. Prefer to keep the
PAH forecast area dry for now. By Saturday night, clouds will be
on the increase ahead of our next weather system. South winds and
increasing clouds will keep temperatures very mild, with lows in
around 60 degrees, which is about 15 degrees above seasonal

.LONG TERM...(Sunday through Thursday)
Issued at 252 PM CDT THU APR 10 2014

Shower and thunderstorm chances begin to increase from west to east
on Sunday as a slow moving storm system approaches from the plains.
Shower and thunderstorm activity will be widespread Sunday night and
Monday as the system slowly crosses the region. Severe weather
probability with the system does not appear to be an issue at this
time. Precipitation associated with this system will taper off from
west to east Monday night. Storm total precipitation should average
between one half and one inch.

For the remainder of the long term period high pressure at the
surface and weak ridging aloft should keep the region dry.
Temperatures on Sunday are expected to be well above normal with
highs in the mid 70s. Beyond that in the wake of the aforementioned
storm system temperatures will be well below normal, however will
tend to moderate back toward normal by the end of the period.


Issued at 1125 PM CDT THU APR 10 2014

Incoming front will tend to dissipate as it approaches.
Showers/isolated storms to the north of the area will sag south
throughout the night but the coverage does not look too
least not enough to warrant more than a vicnity mention at this
point. Winds could continue to be gusty from time to time through
the night but as the front moves in...the winds should diminish.
Cloud coverage should also increase but remain VFR. As the front
settles into the area on Friday...we could see some scattered
convection during the day, which if it does occur, should impact
mainly KPAH.
