Area Forecast Discussion

309 AM CDT Sun Sep 8 2013

.DISCUSSION...
ISSUED 309 AM CDT Sun Sep 8 2013

SHORT TERM...Today through Tuesday

Isolated showers and high-based thunderstorms have been
percolating across mainly the northwest third of the CWA early this
morning. This is occurring in an area of moisture convergence,
ahead of a weak shortwave in southeast IA, and ahead of a weak
front which was drifting south through eastern IA and northern IL.
Latest surface analysis also placed a subtle frontal wave in
extreme SE IA which was aiding in ascent. SPC mesoanalysis showed
MU CAPES up to 1k J/kg in a region of 30 kts effective bulk shear
NW of the IL River, which was allowing a few stronger updrafts to
develop. As these synoptic features gradually shift south today,
widely scattered showers and thunderstorms can be expected.
Forecast soundings continue to indicate a warm wedge off the
surface which will keep any storms rooted around the 7k ft level.
With easterly flow developing in the frontal zone and anticipated
mid-level clouds highs have trended highs towards the mid 80s for
the north half, while some 90 degree readings possible especially
south of the boundary. This boundary loses definition this evening
as it shifts through the southern CWA, as stronger low pressure
develops over the northern Plains and broad southerly flow gets
re- established over much of the Midwest. Any lingering evening
showers across the south should dissipate as frontal convergence
is lost.

Monday and Tuesday still look like the hottest days of this
forecast package. Low pressure tracks into the northern Great
Lakes, slowly dragging a cold front into the Upper Midwest. South
to southwest flow ahead of the front brings the Plains thermal
ridge up across the CWA and should produce widespread low to mid
90s highs. Mid to upper 90s may be possible Tuesday across the
west as more favored southwest sfc winds blow ahead of the front
dropping into northern IL. This would approach records for the day
which are 97 at Peoria and Lincoln, and 98 at Springfield. A mid-
level wave rotating around the west side strong mid level ridging
over the southeast U.S. could spark scattered thunderstorms in the
Ohio Valley region Tuesday afternoon, and will need to monitor
this as it could affect the SE CWA but kept out of forecast as
focus should be farther to our east.

LONG TERM...Wednesday through Saturday

The cold front dropping through the area Wednesday/Wednesday night
brings the only chance of rain in the extended forecast. Prospects
for beneficial rains still look low given confluent mid level
flow, weak convergence along the boundary, and a lack of deep
moisture. Therefore have kept pops at low chance. Current timing
brings front near the I-72 corridor by late afternoon, so another
day of 90+ heat for the south half is possible.

Thursday through Saturday will be dominated by a large Canadian
high pressure ridge shifting across the Great Lakes. Low level
cold advection lags initial frontal passage, so Thursday will
still be several degrees above normal with highs in the mid 80s.
As the ridge shifts into the western Lakes Thursday night and
Friday, northeast winds will bring a more seasonable airmass into
the region. There are signs this respite from the heat will be
short-lived, as mid-level ridging over the Plains brings rising
heights back to the region by late next weekend.

.AVIATION...
ISSUED 1100 PM CDT Sat Sep 7 2013

Latest surface analysis indicating a weak cool front edging slowly
south from just north of ORD west-southwest thru southeast Iowa.
Widely scattered showers were occurring along the boundary and that
will be the main forecast concern overnight along with the potential
for some brief mvfr cigs immediately behind the cool front by dawn
Sunday, affecting mainly PIA and BMI. Rather low confidence on
placement of any showers tracking east southeast into our area
overnight so VCTS or VCSH should cover it as even if we do get a
shower to pass over a TAF site, cigs will remain VFR as it looks
now. Forecast soundings do try to bring some mvfr cigs south to north
central IL by morning which may affect PIA and BMI for a time in the
12z-16z time frame. Will continue with previous trends in keeping a
lower scattered group for now and see how the lower cigs progress
south overnight.

Forecast soundings also indicating the potential for some sct-bkn
cumulus to develop by late morning or early afternoon just behind
the frontal boundary...which by early afternoon should be south of
the TAF sites. Surface winds tonight will be light from a southeast
to south direction, and then as the front pushes thru the area, winds
will shift into an easterly direction at 7 to 12 kts on Sunday.
