.FORECAST UPDATE...
Issued at 916 AM EDT Sun May 10 2026

Other than areas of mid level clouds lingering across south central
Indiana...skies were sunny across the region as high pressure builds
in from the north. 13Z temperatures were largely in the 50s with
N/NE winds.

Quiet Mothers Days anticipated for the area as high pressure settles
across the lower Great Lakes. The mid level clouds will gradually
shift closer to the Ohio River as deeper moisture is forced into the
Tennessee Valley. Cannot rule out a few flattened cu underneath the
mid level inversion noted on model soundings for the afternoon but
the lack of appreciable moisture through the boundary layer will
largely limit clouds to thin cirrus.

Low level thermals support highs rising into the mid 60s to lower
70s from north to south. Zone and grid updates out.

.DISCUSSION (Today through Saturday)...
Issued at 336 AM EDT Sun May 10 2026

Dry conditions to return over central Indiana by daybreak as a few
overnight showers yield to Canadian high pressure arriving on light
northerly winds.  This larger air mass will slowly cross the Great
Lakes/Midwest through the early week, bringing another cooler trend
of cool overnights and slightly below normal afternoon readings to
the Hoosier State.  Expect April-like conditions to prevail both
today and Monday, with partly to mostly sunny skies and light cold-
advective breezes promoting highs in the mid-60s to around 70F.
Despite light overnight winds, any frost potential should be
thwarted by low dewpoints limiting condensation, and temperatures no
lower than the low to mid-40s.

Amid steady northwest flow aloft, upper riding on Tuesday and
strengthening south-southwesterly breezes to return seasonably warm
conditions with 70s and dewpoints climbing to 50F by late day.
Broadening short wave pushing through the Great Lakes will bring a
better chance for organized convective showers around the Tuesday
night timeframe along with overall isolated thunder.  Mediocre
duration of better precipitable water and better forcing staying
north should limit any non-zero severe threat, with light rainfall
most likely northeast of Indianapolis.

Remainder of the forecast period to feature an upper ridge building
over the western US...across the Plains and into the Midwest as a
generally zonal flow aloft.  Next round of northern high pressure to
hold mainly near-normal temperatures and rain-free conditions
through the remainder of the mid-week...before possibly more
pronounced moderation towards the weekend which would include
chances for at least widely scattered showers to end the long term.

.AVIATION (12Z TAF Issuance)...
Issued at 648 AM EDT Sun May 10 2026

Impacts:

- Light winds backing steadily within 320-040 degrees this morning

Discussion:

VFR conditions to prevail near central Indiana terminals through
Monday morning.  Anafrontal mid cloud currently departing the region
to the east will be replaced by a couple rounds of mainly FEW/SCT
high cloud. Light, mainly north-northeasterly winds early this
morning will back slowly to 320-350 degrees by 18Z this afternoon
as an axis of high pressure builds east across the southern Great
Lakes. Winds will increase slightly through midday to 5-10KT this
afternoon.

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