.KEY MESSAGES...
- Unseasonably warm and windy through Saturday, with highs in
the 70s. A wind advisory is in effect after midnight into
Saturday evening. Gusts up to 45 to 55 mph are expected, with
the strongest gusts most likely Saturday afternoon.
- Burning is not recommended Saturday as any fires will be
difficult to contain and could quickly get out of control.
- Strong to severe storms are possible late tonight into
Saturday morning and then again Saturday afternoon. Damaging
wind gusts are the primary threat. There is an isolated
tornado threat late tonight into early Saturday, mainly west
of Interstate 69.

.UPDATE...
Issued at 1051 PM EDT Fri Mar 14 2025
Opted to go ahead and upgrade the high wind watch to an advisory
for the entire area, and expand the advisory to start after
midnight tonight and continue through 8 pm EDT Saturday evening.
Also adjusted the gale warning on Lake Michigan with similar
timing. We've decoupled as of this writing, with gusts mainly
in the western half around 20 to 25 mph range. Expect sustained
winds and general gustiness to increase out ahead of the
approaching line of storms (non- convective gusts), as has been
happening upstream. Further south gusts of 45 to 60 mph have
been observed ahead of the line associated with a deeper mixed
layer, and with the stronger jet building in aloft, winds around
40 to 60 knots will be at about 2-3Kft. Once that better mixed
layer moves east we could start seeing the stronger gusts reach
the surface.
Within the line of approaching showers and thunderstorms, it's
possible we have even higher wind gusts-hence the
enhanced/slight risk for severe weather west of I 69. The
primary threat with this line of showers and storms is damaging
winds (one gust up to 75 in Clinton Co, IA; up to 70 in
Cambridge, IL, others in the 45-60 mph range as of now),
however an isolated tornado risk cannot be ruled out (QLCS). The
best potential for any tornadoes would be further west and
south, especially west of IN-15 where deeper moisture may pool
(lower LCL's).
We may see a brief lull in the winds after the line goes
through, but by Saturday afternoon we'll see gusts up to 45 to
55 mph. A few gusts up to around 60 mph are possible, however I
think they will be isolated so felt more confident in advisory
criteria (versus going full blown warning). There are questions
with respect to cloud cover/mixing profiles during the day-how
the overnight/early convection impacts the environment. The
potential remains for additional severe threat Saturday
afternoon, and will depend once again on how things evolve
tonight-early Sat.

.DISCUSSION...
Issued at 158 PM EDT Fri Mar 14 2025
Intense shortwave disturbance over nwrn OK will deepen newd into se
MN by daybreak tomorrow. Stout sfc dryline through ern KS/wrn MO
already sparking storms and expect these will explode going forward
through this aftn as broad downstream warm sector continues to
moisten. 12Z guidance though had trended slower with ewd progression
of what should be an extensive but weakening line of storms late
tonight. Presence of LLJ near 80kts would usually portents some risk
for damaging winds however stable boundary layer beneath marginal
instability wedge aloft curtails a more certain svr storm risk.
Strong secondary frontal wave development within base of sharp upper
trough over the lower OH valley tomorrow aftn will rocket newd into
se ON by daybreak Sun. Wrn bound of stalling composite frontal zone
uncertain but most likely to lie near the IN/OH stateline. Svr
risk through wrn OH looks limited here as mid MS valley storms
dominate Sat aftn and evening and limit better moisture flux
farther north. Otherwise primary question Sat is gradient wind
risk as boundary layer heats through the morning beneath tail of
exiting LLJ streak. Suspect morning cloud debris will limit a
deeper mixed layer from developing and thus limit gust potential
to aob 40kts. Not confident enough to sandbag high wind watch
as mid morning LLJ still quite strong, in excess of 55kts and
will punt headline decision to overnight shift.
Thereafter buckle up with a general windy week ahead with widely
ranging temperatures as flow aloft convulses in response to strong
plains cyclogenesis mid week with rain changing to snow and sharply
colder temps Thu-Sat.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 1144 PM EDT Fri Mar 14 2025
Strong to severe storms over IL were moving rapidly east.
Adjusted time & impacts slightly based on radar, sfc obs and
high res model trends. There should be a fairly small window
with the passage of the showers and storms when gusts greater
than 40 knots are possible. More rain is expected late in the
TAF period as the upper level trof moves east. Low MVFR and
possibly IFR ceilings are expected.
