335 AM EDT Fri Jun 5 2026
.KEY MESSAGES...
- Pleasant again today amid increasing winds...gusts to 20-30 mph
this afternoon
- Chances of showers/t-storms north late today/tonight...more
widespread showers possible late Saturday-Saturday night
- Very warm and humid starting Sunday, periods of showers/t-storms
&&
.DISCUSSION (Today through Thursday)...
Issued at 335 AM EDT Fri Jun 5 2026
Transition from recent pleasant early-summer conditions to prolonged
more-humid, and at times unsettled mid-summer pattern...to occur
today and Saturday. Increasing, quasi-stacked southwesterly flow
today to boost precipitable water aloft and surface
dewpoints...although better forcing sliding by to the northwest of
the region should only allow a few showers/stray rumble of thunder
along the Upper Wabash Valley through early evening.
Several opportunities for showers and generally non-severe t-storms
will follow tonight through Saturday night as small ripples of
forcing slide west to east amid an overall zonal pattern...with
cross product of these ingredients most likely north of I-70. Cannot
rule out a couple marginally strong/severe gusts late tonight north/
west of Crawfordsville...although best chances for any organized or
stronger convection will be Saturday night, especially along an axis
north of the I-74 corridor, when marginally strong/severe gusts and
perhaps isolated large hail are on the table.
Upper pattern to then rearrange into another H500 subtropical ridge,
this time with the quasi-stationary axis aligned from the Great
Lakes into eastern Canada...which will favor deep Gulf moisture into
Indiana through much of the remaining period. High humidity can be
expected, will dewpoints trending from upper 60s by Sunday morning,
into at least the low 70s by Tuesday. Scattered to at times
numerous showers and at least a few embedded t-storms can be
expected through at least Wednesday. One low-confidence variable
will be short wave/ vort max spinning northeastward through the
western Midwest early next week which could enhance convection and
present a greater potential for strong/severe cells...and possibly
less-active conditions in its wake.
Potential for isolated flash flooding will trend upward through the
early week for any areas receiving multiple rounds of heavier rains.
Temperatures to range from lows near 70F to highs in the 80s under
often considerable cloudiness. Potential for first-90s by the late
week should the upper ridge build over the central US and allow
ample sunshine back into Indiana. Indianapolis` highest reading so
far this year was 88F on March 22.

.AVIATION (06Z TAF Issuance)...
Issued at 1232 AM EDT Fri Jun 5 2026
Impacts:
- Wind gusts peaking at 20 to 25kts this afternoon
- Scattered showers and storms possible near KLAF this evening
Discussion:
Predominantly VFR conditions are expected through the forecast
period.
High pressure will remain the primary feature impacting the Ohio
Valley for much of today as it shifts into the southeast States.
This will enable the frontal boundary focused from the upper Midwest
through the central and southern Plains to move closer to the region
by this evening. Deeper moisture advection will commence as Gulf
moisture is drawn north on the back side of the high. This will
result in greater diurnal cu coverage for this afternoon along with
a steady increase in mid and high clouds. Potential is there for
scattered convection to impact KLAF by this evening but primary
impacts from rain and storms should hold off at the terminals until
late tonight into Saturday.
Southwest winds will gust up to 20 to 25kts at times this afternoon
then diminish to light southerly tonight.

.IND WATCHES/WARNINGS/ADVISORIES...None.
