.DISCUSSION...
Issued at 256 AM CDT Thu Jun 6 2024

There is a secondary cold front entering central Illinois this
morning. This will help dry us out the rest of the way, dropping dew
points into the upper 40s to low 50s during the day. Behind the
front, the pressure gradient has tightened and will deliver some
breezier gradient winds to the CWA. The 00z HREF shows a 40-60%
chance of wind gusts greater than 30 mph this evening after 5pm.

Starting Friday, the synoptic pattern has an unseasonably deep upper-
low anchored over Ontario and the Great Lakes and a strong high over
the Desert Southwest into the Southern Plains taking a stronghold
over central Illinois. Central Illinois will remain sandwiched
between these two features embedded within deep-layer northwesterly
flow. The forecast will remain mostly dry, but some MCS activity
this weekend to our south/southwest could bring some rain up our
way. There is a slight chance (15-30%) that the precipitation could
be as far north as a Lincoln to Champaign line Saturday afternoon
through Sunday morning.

The temperatures will continue to be slightly below normal through
the extended forecast. High temperatures stay in the mid to upper
70s through next Wednesday, before warming back up into the 80s to
near 90 for late next week. Overnight lows will dip down into the
50s through Tuesday night, warming back into the 60s for late week.
