Area Forecast Discussion
National Weather Service Lincoln IL
315 PM CDT Mon Jun 26 2017

.SHORT TERM...(This evening through Tuesday)
ISSUED AT 315 PM CDT Mon Jun 26 2017

A weak front will continue to move south through the CWA this
evening. The clearing that has occurred has allowed some heating
and instability to occur/develop over parts of the area. Isolated
to scattered showers and storms will remain possible late this
afternoon through early this evening. The precip should wane
around sunset leaving the remainder of the evening dry with skies
becoming clear. Dry weather is expected then to build into the
area late tonight and into tomorrow as high pressure builds into
the region.

Temps will remain on the cool side tonight and through tomorrow.


.LONG TERM...(Tuesday night through Monday)
ISSUED AT 315 PM CDT Mon Jun 26 2017

High pressure will continue to dominate the weather across the
area Tue night as the pattern becomes more zonal. Then another
weather system will quickly move into the area beginning Wed. As
the front moves through the CWA it will become parallel with the
flow by Thur and then sit somewhere over the area through the rest
of the week. Models appear to be in fairly good agreement with the
front draped across central IL through this period, which means
showers and storms will remain possible. Models also look similar
with timing of individual waves moving along the front so
consensus forecast of likely pops somewhere in central IL Wed
night through Fri looks like a good forecast at the moment. Into
the weekend the front should get pushed out of the area to the
southeast. However, additional chances of precip will return for
later part of the weekend and into the beginning of next week as
the pattern returns to a somewhat northwest flow with a upper
level trough over the Great Lakes region.

Temps will also get warmer again ahead of the next system and then
remain that way through the week, evening with precip/clouds and
the front somewhere across the area.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1229 PM CDT Mon Jun 26 2017

A weak front will slide south through the area this afternoon.
Cloud cover will limit heating and instability along and ahead of
the front so will just have VCSH at all TAF sites for this
afternoon and into early this evening at SPI/DEC/CMI. Cloud cover
will remain mostly mid clouds around 8-10kft but some lower
scattered clouds are possible with a passing shower. Once the
front moves through late this afternoon to early this evening,
clouds will quickly scatter out and high cirrus will be left.
Winds will westerly with gusts to around 20kts this afternoon then
become light and variable remainder of the forecast period behind
the front as high pressure builds into the area.
