.NEAR TERM...
(Today)
Issued at 431 AM CDT Sun Apr 27 2025

An upper level low moving across the New England region, as it
departs the coast, will induce upper level ridging across the
southern CONUS. A surface high situated over the Great Lakes will
bring drier and somewhat cooler air across the area. A larger
temperature/dewpoint separation and a light NE flow for the most
part has hampered development of fog unlike last night. There was
earlier fog development in those more sheltered valley locations
like DeKalb county. The fog had dissipated as drier air filtered
in.

An area of high altitude clouds from dissipating complexes that
brought convection across AR/LA to MO were moving across this
region. Showers associated with those systems were also fading as
they moved into a generally drier environment under the influence
of the Great Lakes high. Thus am staying with a dry forecast to
start off the week. Under partly cloudy skies, high temperatures
should rise into the mid 70s to around 80 with light NE-E winds.

.SHORT TERM...
(Sunday night through Tuesday)
Issued at 1033 PM CDT Sat Apr 26 2025

A frontal boundary is forecast to move back into the area Monday
from the southwest, allowing low rain chances (20% or less) Monday
afternoon into Tuesday. However, dry conditions will likely
persist through mid week as upper level ridging continues to
influence the area from the west. During this time, high
temperatures are forecast to reach the low to mid 80s with
overnight lows in the 50s-60s.

.LONG TERM...
(Tuesday night through Saturday)
Issued at 1033 PM CDT Sat Apr 26 2025

An upper level shortwave is forecast to move in from the west by
mid week, bringing low chances of shower/storm chances to the area
on Wednesday before they increase on Thursday to medium to high
chances. Any shower development on Thursday will have a low chance
of becoming strong as the environment continues to look favorable
for threats of gusty winds and small hail in addition to moderate
to heavy rainfall. Friday, low to medium rain chances continue
into the afternoon with a cold frontal passage. Zonal flow is
forecast to replace this and subsequent dry conditions return to
the area to end the week. We have low confidence in timing and
chances of this system due to it being several days out, but we
encourage everyone to check back in for updates throughout the
week. Otherwise, high temperatures during this time are forecast
to reach the 70s-80s with overnight lows in the 50s-60s.

.AVIATION...
(12Z TAFS)
Issued at 631 AM CDT Sun Apr 27 2025

VFR weather should continue for the TAF. Surface high pressure
over the southern Great Lakes will build across the western Mid
Atlantic by this evening. A weak upper level disturbance over the
Mississippi Delta will move east, bringing slightly higher amounts
of lower level moisture. Daytime heating should result in the
formation of cumulus, and maybe a few towering cumulus this
afternoon. Although a brief shower cannot be ruled out, chances of
them impacting a terminal are too low for inclusion in the TAF.
NE-E winds this morning will veer to a SW direction at KHSV this
afternoon, and should remain more from the E at KMSL. Winds will
become light and variable shortly after dusk.
