.DISCUSSION...
Issued at 238 PM CDT Fri May 22 2026

Rain is tapering off this afternoon from the southwest to the
northeast. The remaining areas of precipitation along and north of I-
90 will continue to taper off and move northeast over the next few
hours. An additional line of weak showers is forming along the
leading edge of an occluding front just west of the James River
Valley. No severe weather is expected from this line. However, the
southern portion as it passes through areas south of Highway 18 may
produce some thunder and gusty winds to 45 mph. As far as rainfall
totals are concerned, an additional tenth or two is possible along
and north of I-90.

Early Saturday morning patchy fog is possible as low temperatures
approach dew points in the 40s. Fog is expected to burn off by mid-
morning. Clouds will scatter out through the day becoming mostly
sunny by afternoon. Winds will be light out of the west and highs
are expected to climb into the upper 60s and 70s. Modest mid-level
moisture advection and weak elevated instability may result in
isolated to scattered light showers and thunderstorms Sunday. Sunday
will be warm with highs in the upper 70s and 80s. Late Sunday night
into early Monday morning better dynamic parameters may allow for a
few isolated strong to severe thunderstorms for areas along and
south of Highway 18. This area is currently under an SPC Day 3
Marginal outlook (level 1 of 5). Monday is expected to be even
warmer with highs in the mid 80s to low 90s, with the warmest
temperatures expected along and west of the James River Valley.
Monday will also be on the muggy side with dewpoints in the mid 50s
to low 60s.

Periodic rain chances remain in the forecast for the remainder of
next week. The next best chance for stronger thunderstorms looks to
be Thursday, however details at this time are lacking. Highs for
Tuesday will once again be in the mid 80s to low 90s. The rest of
the week highs will generally be in the 80s.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1247 PM CDT Fri May 22 2026

Showers and thunderstorms have begun to wane this afternoon. Areas
to the east of I-29 will continue to see more organized showers and
possibly a thunderstorm or two for the next couple hours.
Precipitation should be fully clear of the area by early evening
tonight. A mix of MVFR down to LIFR ceilings and visibilities will
improve in concert with the showers as they move to the northeast.
VFR conditions should be widespread once again around midnight.

Afternoon winds are southeasterly ahead of the surface front,
becoming westerly behind. Breezy gusts of 15-25 kts will taper off
after sunset becoming light. As they do so patchy dense fog may
develop early Saturday morning. Any fog should burn off by mid-
morning.
