Area Forecast Discussion
National Weather Service Lincoln IL
622 AM CDT Thu May 4 2017
.SHORT TERM...(Today and tonight)
ISSUED AT 323 AM CDT Thu May 4 2017
Deep and slow moving storm system currently to the south/southwest
over Central Arkansas this morning continues to bring plenty of
rain to the region. Rain this morning heaviest to the south and
east of the IL River Valley. This general area expected to
continue to see rain through today and slowly shift eastward
through the overnight. General instability is limited and forecast
soundings keep a very weak lapse rate over the FA should limit
thunder...though proximity of the low/trof later this afternoon
could result in some scattered thunder mainly S of I-70.
Windy day expected with a tightening pressure gradient as well as
the wind just off the surface in excess of 30 kts mixing down with
some of the showers/rain. Not quite to wind advisory
criteria...but will have to be watched with the 12z soundings to
see some of the momentum transfer potential. Flash Flood Watch
remains in place with more rain expected throughout the day and
saturated ground in place...and another inch or so possible today.
Cool temps with all the cloud cover and rain...similar tonight
until the rain moves out...with winds staying up through the
overnight hours.
.LONG TERM...(Friday through Wednesday)
ISSUED AT 323 AM CDT Thu May 4 2017
No significant changes to the forecast as the models are painting
similar pictures with the slow movement of the deep low through
the Ohio River Valley through the end of the week. Rain chances
extending through Friday in the south and east. Sunshine in the
west slowly trying to bring temps back up to low 60s in the west
on Friday...and across the entire area on Saturday. Warmer temps
under the western ridge start to edge into the Midwest behind the
slow exiting trough...with sunshine trying to rebound the temps to
more springlike conditions. Prev solutions brought another round
of precip to at least eastern IL...potentially over the
weekend...and the 00Z ECMWF is even more heavy handed with that
wave...but Saturday forecast has only minimal pops for lack of
confidence. Windy conditions expected to continue Saturday in the
wake of the system. Winds come around to include a more southerly
component for the beginning of next week...with a slow increase
in temperatures. Pops kept to a minimum in the extended forecast
until the end of next week.
&&
.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 609 AM CDT Thu May 4 2017
Not much of a shift in the forecast...mainly rain... PIA on the
edge of the showers now...eventually SPI will follow suit as the
showers drift eastward. Taking the cigs down to IFR in some
locations...and bouncing btwn IFR and VFR in others. Strong
winds, gusting to 30-35kts later today...between the pressure
gradient and showers mixing down some higher gusts from just off
the surface. Keeping winds up through the overnight hours. Previous
guidance tried to hint at a LLWS issue...but has been marginal
after midnight tonight and very low confidence so for now it has
been left out.
