.SHORT TERM /THROUGH TONIGHT/...
Issued at 208 AM CDT Sat Apr 25 2026

High pressure centered across the region will continue to bring
quiet, pleasant weather to the area through tonight. Morning
clouds are possible in northwest Illinois north of Interstate 80
as clouds over southern Lake Michigan expand westward prior to
sunrise. Abundant sunshine today will push high temperatures
into the lower to mid 70s. Clouds will increase across the area
Saturday but low temperatures will be similar to this morning
with temperatures in the 40s.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 208 AM CDT Sat Apr 25 2026

On Sunday, the flow aloft across the area will become more
southwesterly as 500 MB ridging builds to our east and the
closed 500 mb low over Saskatchewan and Manitoba wobbles
northeastward. It will be quiet through the day on Sunday with
temperatures slightly warmer than Saturday with high
temperatures once again in the lower to mid 70s.

Sunday night, a shortwave trough is forecast to move from the
Great Basin into the Plains with several disturbances ejecting
towards the area ahead of that trough. A low level jet of 30 to
40 knots will develop to our west Sunday evening and veer
across the area overnight leading to moisture and warm advection
across the area. This will also lead to the development of
showers and thunderstorms across the area overnight into Monday
morning.

On Monday, a negatively tilted shortwave is forecast to lift
from Colorado/Kansas northeastward into the Great Lakes by 12
UTC on Tuesday with the surface low following a similar path.
The 00z GFS has trended farther to the south with the surface
low into Missouri while the ECWMF, Canadian, and NAM have the
surface low lifting into Minnesota The track of the surface low
will impact moisture and instability across the area on Monday
with a more southerly surface low pushing the instability to
the south and east of the area. Deterministic models show at
least moderate instability developing Monday afternoon/evening
across the warm sector, along with strong deep layer shear as an
upper jet overspreads the warm sector ahead of a surface low.
Machine learning guidance (NCAR/NSSL/CSU) has the highest severe
weather probabilities shifting southeastward with the 00z run.
With that said, SPC has a level 3 of 5 risk across the entire
outlook area for Monday. While the details are unclear this far
out, all severe weather hazards will be possible with favored
timing of the strongest storms during the afternoon and evening.
Stay tuned to the forecast through the weekend!

Tuesday On: Broad trough is forecast to move into the eastern
two thirds of the CONUS. The current forecast is dry for
Tuesday and Wednesday. Deterministic models and ensembles show
a more developed wave diving into the Upper Midwest Thursday
into Thursday night with low chances for rain. Temperatures
during this period will be near normal for the end of April with
high temperatures in the upper 50s to mid 60s and lows in the
upper 30s to lower 40s.
