.KEY MESSAGES...
- Drier and cooler weather through Tuesday
- Freeze Warning in effect for northern half of central Indiana late
tonight into Tuesday morning, frost development possible further
south though confidence is limited
- Warming trend begins Wednesday and continues through next weekend
- Isolated to scattered rain chances return Thursday onward, which
may bring receding rivers back into flood in some areas
&&
.SHORT TERM (This evening through Thursday)...
Issued at 252 PM EDT Mon Apr 6 2026
Mostly quiet weather conditions are expected through the middle of
this week under the influence of a Canadian surface high. Winds are
currently gusting between 20-30 mph due to deep mixing and sunny
skies ahead of the building surface high. Look for these gusts to
diminish towards or shortly after sunset once mixing is cutoff.
Cooler conditions will continue through Tuesday thanks to cold air
advection before the high pressure then shifts eastward allowing
temperatures to quickly warm up. Highs in the mid 40s to low 50s
Tuesday should warm well into the 60s by Wednesday and possibly
near 70F for far SW counties.
A Freeze Warning is in effect late tonight into Tuesday for the
northeast half of central IN, from 2 to 10AM Tuesday. as
temperatures at or below freezing are likely. The Freeze Warning
does include the Indianapolis metro, but nearby surrounding areas
could remain above freezing due to urban heat island effects. Frost
development is possible further south, but there are a few limiting
factors. Winds remaining slightly elevated, increasing clouds late
overnight, and relatively marginal temperatures leads to lower
confidence on frost potential. Some patchy frost still appears
possible and more widespread frost formation cannot be ruled out if
radiational cooling conditions become more favorable.
Make sure to cover any sensitive outdoor plants, even those not
included in the Freeze warning due to some potential for frost.
There is additional frost/freeze potential Tuesday night as lows
will be in the low-mid 30s. The freeze potential is mainly confined
to far eastern counties where temperatures could fall to 29-32
degrees. Winds remaining slightly elevated and additional clouds
moving in overnight limits confidence for the frost/freeze potential
once again.
An approaching system Thursday will promote breezy conditions. Dry
weather should persist due to lingering subsidence induced dry air
across the area. Rain chances return later in the week with more
details regarding this in the long term discussion.
&&
.LONG TERM (Thursday night through Monday)...
Issued at 252 PM EDT Mon Apr 6 2026
Expectation for late this week into the weekend remains a return to
above normal temperatures and a potential return to active weather.
The strong Canadian high will be off the east coast by 00Z Friday,
with a northern stream low near James Bay and moving rapidly
eastward. An elongated cold front stretching from this low back to
the central high Plains will stall somewhere near the region late
week and may produce multiple opportunities for convection, though
model disagreement precludes more than chance PoPs. Potential will
exist for multiple rounds of precipitation, which could prolong or
exacerbate ongoing flooding on main stem rivers given antecedent
conditions as a result of the wet weather in recent weeks.
Hydrologic ensembles do show renewed river rises next weekend in
response to this potential rainfall, though a mostly dry week will
help to hopefully blunt these impacts a bit.
There is little to indicate significant severe threats during the
latter portion of the forecast, and this is backed up by
experimental machine learning guidance. That said, week two outlooks
continue to indicate enhanced likelihood of warmer than normal and
above normal precipitation conditions, thus we may well be back in
an active pattern for mid to late April.

.AVIATION (18Z TAF Issuance)...
Issued at 142 PM EDT Mon Apr 6 2026
Impacts:
- Wind gusts 20-27KT from 300-310 degrees through 00Z this evening
Discussion:
Deep PBL mixing and a passing front earlier in the day will continue
promoting strong winds with sustained winds peaking at 15-19KT and
gusts as high as 20-27KT through the afternoon. Winds and gusts will
subside after sunset, but remain slightly elevated across northern
portions of the area.
A few fair weather cu and thin high clouds will be possible at the
sites today, though skies should remain mostly clear. A slow
increase in clouds can be expected by late tonight.
