.Short Term...(This Evening through Tuesday Night)
Issued at 243 PM EDT Mon Apr 12 2021
Thicker stratocu has finally shifted east and is now as of mid
afternoon impacting just the far northeast portions of central
Indiana. Elsewhere...cumulus lingers but is gradually scattering as
drier air advects in from the west. Despite gusty westerly
winds...temperatures have warmed nicely with 1830Z readings now in
the low to mid 60s over much of central Indiana.
A largely quiet weather pattern will establish through the short term
with just a small threat for very light rain in far southern
portions of central Indiana late tonight and early Tuesday.
An elongated west-east upper level trough will continue to organize
across the northern tier of the country largely aided by a deep
cutoff upper low over the Upper Midwest this afternoon. This feature
will drift E/SE into the Great Lakes through Tuesday night as energy
aloft carves out an anchor low over the Intermountain West. South of
these dual waves aloft...expect quasizonal flow with weak ridging
tonight and early Tuesday being replaced by falling heights as the
primary upper low shifts into the Great Lakes. At the surface...an
inverted trough over Texas this afternoon will sidle east/northeast
into the Tennessee Valley by early Wednesday with multiple surface
waves traversing the boundary.
Moisture aloft will organize along the northern flank of the
inverted trough this evening and shift northeast into the Ohio
Valley overnight. Initially...a bank of mid level clouds across
Kansas and Missouri this afternoon will lift into the southern half
of the forecast area this evening. As isentropic lift increases
subtly late tonight across the Ohio Valley...light rain showers may
develop over far southern portions of central Indiana. CAMs analysis
attempting to pull light rain even further north briefly reaching
the I-70 corridor in the predawn hours before pulling back south.
All of the moisture further north across the forecast area however
is confined above 700mb with little to no isentropic lift present in
the associated 300k layer. With that in mind...have a hard time
seeing more than sprinkles north of a Sullivan-Bloomington-
Greensburg line and even that may be generous. As the axis of mid
level moisture transitions east Tuesday morning...any light rain
showers will go with it and should have all precip out of southern
counties by midday or shortly after.
Mid level clouds that overspread much of the southern half of the
region this evening will take until Tuesday morning to shift back to
the southeast. Model soundings and RH progs show much drier air
residing through the column just north of the mid level moisture
axis with this area of drier air expanding back south and leading to
increasingly sunny skies over much of the forecast area for Tuesday
afternoon. Clouds are likely to expand back into the southern
forecast area from the south Tuesday night as another surface wave
tracks along the inverted trough to the south. The axis of deepest
moisture though will remain near and south of the Ohio River through
Wednesday morning.
Temps...even with cloudy periods...low temperatures should have no
trouble falling into the lower and middle 40s both tonight and
Tuesday night. There is even some potential for a few spots in
northern counties to slip into the upper 30s. An overall model blend
will work well both nights. With a subtle delay in the arrival of
cooler boundary layer air until Tuesday night...highs on Tuesday
will likely approach readings being experienced this afternoon with
highs into the 60s.

width, destroyed 235 of 247 buildings, leaving no trace of lumber or
contents in many cases. Many survivors were bruised by large hail which
fell after the passage of the tornado. (David Ludlum) (The Weather Channel)
...1934...
Winds atop Mount Washington NH averaged 186 mph for five minutes, with a
peak gust of 231 mph, the highest wind speed ever clocked in the world.
(David Ludlum)
...2001...
A record high temperature of 85 degrees was recorded at the Jackson Weather
