POTENTIAL RAINFALL

TODAY’S MAP

NWS TECHNICAL DISCUSSION

The pesky upper low will continue to influence the weather across
central Indiana through the short term.

Energy rotating around the upper low will bring some showers to
northern portions of central Indiana early this morning, while
forcing to the upper low itself will keep some rain across the far
southern forecast area. Patchy light rain will be in between.

During the day today, the upper low will drift northeast through
Kentucky and weaken some. At the surface, a weak low will weaken
as it lingers. Forcing from these will be enough to keep some chance
PoPs across the area.

Although temperatures warm some aloft today, some breaks in the
clouds could produce a bit of instability, which will aid in
producing the scattered showers. However, feel that instability
will remain low enough to leave out mention of thunder for now.

Clouds will lift today. resulting in better insolation at the
surface. The will allow temperatures to reach around 60 for
highs.

Tonight, the upper low will move northeast into Ohio. At the
surface, a stronger trough will move into the northeast forecast
area. This will be enough for some high chance to low end likely
PoPs there, with lower PoPs to the southwest.

Low temperatures will be in the mid 40s to near 50.

.LONG TERM (Tuesday through Sunday)...
Issued at 236 AM EDT Mon May 5 2025

Continue to expect a somewhat blocky and stagnant pattern in the
long term period, though perhaps a bit more progressive than in
previous forecasts. Guidance continues to trend more toward at least
a brief attempt at a Rex block type pattern that would suppress the
second low currently over the southwestern CONUS more to the south
and leave central Indiana largely drier and with temperatures
seasonably mild, somewhere near normal much of the period.

The first closed low bringing cool and dreary conditions to central
Indiana currently will be on the way out by Tuesday morning,
allowing for gradual clearing and lingering precip chances in the
northeast to come to an end by Tuesday evening.

Surface and upper level ridging now appears likely to exert some
influence over the area, particularly northern portions, leading to
less cloud cover and lower precipitation chances than appeared
likely a few days ago. Will likely have to carry some low shower
chances in the south on at least a couple of afternoons through the
long term, especially as the tail end of the longwave trough that
looks to absorb our current closed low sideswipes the region to the
east late in the week, but no more than 20 percent PoPs are
warranted at this time given model-to-model and run-to-run
inconsistencies.

Temperatures will return to numbers closer to seasonal normals for
the majority of the week. Blend has been trending toward above
normal readings over the coming weekend, but this may be premature
given the intrusion of a second cool airmass with the aforementioned
trough. Needless to say, uncertainties in the forecast grow and
become somewhat significant with time late this week.
