.KEY MESSAGES...
- Warmer temperatures arrive for Sunday, Monday and Tuesday.
- Wind gusts up to 40 mph expected on Tuesday.
- A wet pattern emerges for Tuesday Night through Friday, with
strong to severe storms possible on Tuesday afternoon and night.
&&
.SHORT TERM (This evening through Sunday)...
Issued at 249 PM EDT Sat Mar 28 2026
Relatively quiet weather conditions are expected through the period
as an expansive surface high pressure system moves overhead today.
Southerly flow will return tonight and persist through the rest of
the short term, bringing the region back to above normal
temperatures starting tomorrow. Highs today will range from the
upper 40s to low 50s, dropping to the mid to upper 30s tonight, and
then highs back in the 60s tomorrow.
The high pressure today is providing clear skies and light, variable
winds today. On the backside of the high, however, increasing
pressure gradients could lead to gusts of up to 20 mph to mix down
the surface tomorrow afternoon. Also expecting partly to mostly
cloudy skies at times tonight and tomorrow.
&&
.LONG TERM (Sunday night through Saturday)...
Issued at 249 PM EDT Sat Mar 28 2026
The Ohio Valley will undergo a pattern change this weekend as a CAA
induced surface high will push eastward, eventually parking over the
Western Atlantic, and establishing a typical Bermuda high. This high
will remain stagnant as subsidence beneath an upper level ridge will
reinforce pressure rises over this area throughout the week. With a
strong high over the Western Atlantic, the central CONUS will
experience well above normal temperatures and strong moisture return
as the mean flow remains predominantly out of the S/SW.
The wave count will also increase next week, of which will lead to
consistent precipitation chances beginning early on Tuesday as a
weak frontal boundary progresses through. The rest of the weak will
be greatly influenced by this boundary as it becomes quasi-
stationary near central Indiana, with a 100-150mile corridor of
precipitation within its vicinity from Tuesday night through
portions of Friday. By next weekend, a new trough is expected to
reach the central CONUS, pushing the boundary northward, but with
additional rain/storm chances as the trough nears. Severe
thunderstorms cannot be ruled out, with the best chances being
Tuesday as the front passes, and Sat/Sun within the trough passage.
Total QPF will likely end up well above normal for early April, with
some areas receiving upwards of 4 inches by the end of the week.
Temperatures will fluctuate some due to the placement of the
aforementioned boundary, regardless, daily highs and lows will remain
above normal within predominant S/SW flow aloft. Current expectation
is for highs to range from the upper 50s to upper 70s throughout the
week, with slight adjustments possible depending on timing of cloud
cover and precipitation.

Discussion:

few gusts up to 20kts Sunday afternoon.
