Area Forecast Discussion
National Weather Service Lincoln IL
840 PM CDT Mon Jun 30 2014

.DISCUSSION...
ISSUED 840 PM CDT Mon Jun 30 2014

Initial tornado watch was allowed to expire, as the first wave of
storms passed over the far northern CWA. Some capping has been
keeping storms from firing further south so far this evening,
despite extreme MUCAPE values in the 5000 J/kg vicinity. However,
second line of intense storms currently extending from just west
of Rockford into far southeast Iowa, then back into northwest
Missouri. There will be some battling between the cap in our area
vs the air being worked over already in the north (outflow
boundary has made it between Peoria and Lincoln with temps around
70 north of it). However, the latest HRRR has this lined up fairly
well, and shows the line making it to about Jacksonville and
Bloomington between 10-11 pm albeit in a weakening state. Have
updated the grids to significantly beef up the PoP's and rain
totals in the northwest this evening, and refined the southern
extent. Will send out corresponding zones shortly.

.AVIATION...
ISSUED 642 PM CDT Mon Jun 30 2014

Much of the severe convection that was previously forecast to push
into west-central Illinois early this evening has actually tracked
much further north across eastern Iowa into northern Illinois.
Still monitoring outflow boundary left behind by the storms,
stretching from near KPIA to just north of KMCI. Scattered strong
to severe cells have developed along this boundary across northern
Missouri, and are expected to continue to develop/track
northeastward into central Illinois later this evening. Exact
areal coverage still remains uncertain: however, most model
guidance agrees that at least scattered convection will arrive at
the TAF sites after dark. Will therefore carry a TEMPO group for
thunder at all terminals with thunder threat ending after 07z.
Have downplayed the previous wind forecast as an organized line of
severe convection is no longer expected. Once the storms
dissipate, skies will clear overnight into Tuesday morning.
Forecast soundings are fairly dry for Tuesday, with Cu-rule only
suggesting scattered clouds at around 5000ft.

.PREV DISCUSSION...
ISSUED 338 PM CDT Mon Jun 30 2014

Not many changes overall to the expected weather scenario for the
next week. Discussion will be abbreviated due to ongoing severe
weather preparedness & operations.

SHORT TERM...Tonight through Thursday: Lingering uncertainty
exists with respect to the evolution of the storm complex heading
east across Iowa. Most of forecast area remains in a Moderate Risk
for severe weather through tonight, although the main threat
should be over this evening. Current bow echo, surging east into
northwest Illinois, is expected to stay north of the forecast
area as flow backs southwest ahead of an advancing upper trof.
However, additional development remains possible, and is suggested
by many mesoscale models, along the boundary extending southwest
from the main bow in a strongly sheared and highly unstable
environment. Very heavy rain remains a threat with any storms the
impact the area tonight, with precipitable water values in excess
of 1.5 inches, though rapid storm movement should mitigate the
flooding threat to some degree.

Expect storms to taper off overnight with the loss of diurnal
instability and as the surface cold front sweeps through the area.
The bulk of the remainder of the short term period should be quiet
and cooler than normal. Northwest upper level flow will
predominate, with high pressure at the surface more often than
not. Still signs of a spoke of energy moving through the mean
upper trof around Wednesday, which may bring a chance of rainfall
to the area. However, most of the models are less bullish than
they have been.

LONG TERM...Friday through Monday: Temperatures will begin to
moderate heading into the weekend as low level flow turns
southerly on the back side of the surface high. The turning flow
will also help richer moisture to return to the area. A northwest
flow wave is still expected by late in the weekend, and this will
result in our next organized risk of showers/storms.
