.DISCUSSION (Today through Thursday)...
Issued at 251 AM EDT Fri Jun 19 2026

Today...

Quiet weather is expected today with surface high pressure in
control. Passing high clouds will give way to some cumulus this
afternoon, so skies will be mostly sunny to partly cloudy. Highs
today will be in the middle 70s north to around 80 south.

Tonight and Saturday...

A weakening upper trough will move into the lower Great Lakes by 12Z
Saturday, and an associated weak cold front will move into Indiana.
Moisture will be limited for this system to work with. Still, feel
there will be enough for isolated showers to make it into the
northern forecast area very late tonight into Saturday morning.

By afternoon, forcing will have weakened enough that chances for
showers will be too low to mention, so will go dry. (Odds are very
low but non-zero, so a rogue shower could still pop up Saturday
afternoon.)

Lows tonight will mainly be around 60 with highs on Saturday in the
upper 70s to lower 80s.

Sunday and Monday...

A stronger upper wave and associated surface low pressure system
will move through the area during this time. This system will have
much better moisture to work with good moisture transport into the
area. Forcing combined with this moisture will bring widespread
rainfall to the area, especially Sunday afternoon and night.

In addition, the system will have decent shear and instability with
it. This will lead to a threat of isolated strong to perhaps severe
storms. However, at the moment it looks like heavy rain will be the
main threat. Rainfall totals over 2 inches are possible.

Tuesday and beyond...

Tuesday will be quiet, but a couple of upper systems could bring
rain to the area Wednesday into Friday. Confidence in the strength
and timing of these remains low, so will have some broadbrushed
lower PoPs.

The upper pattern will keep temperatures below normal through the
period.
