.DISCUSSION...
Issued at 318 AM CDT Tue May 19 2026

A cold front pushed through the area overnight, leaving anafrontal 
showers across eastern portions of the CWA early this morning. 
Modified Canadian high pressure builds in through the day, bringing 
drier conditions and a reinforced cool airmass with highs only 
reaching the mid to upper 60s today through Thursday.

The next forecast challenge arrives late Wednesday night into 
Thursday as a mid-level trough emerges from the Rockies and lifts 
northeast across the region. Moisture return remains limited ahead 
of this system, with surface dewpoints struggling to recover into 
the lower 50s. Instability is expected to be minimal as a result, 
keeping severe weather probability low with low QPF amounts expected.

A warming trend takes hold heading into the holiday weekend as the 
pattern becomes more amplified and southerly flow returns. Highs 
climb into the upper 70s by Saturday with lower 80s possible by 
Memorial Day. Increasing moisture return may bring additional 
precipitation chances late in the extended period, though confidence 
remains limited with spread widening amongst the ENS, GEFS and GEPS 
solutions at this range.
