Area Forecast Discussion
National Weather Service Indianapolis IN
251 PM EDT Thu Apr 29 2021

.Short Term...(This evening through Friday night)
Issued at 251 PM EDT Thu Apr 29 2021

A return to quiet weather is in the offing over the next couple of
days as surface high pressure builds into the region. First, though,
an upper level trough axis will move through the area late this
afternoon into this evening. It appears that the extent of the
precipitation along with this trough is the band ongoing from
eastern Michigan down into far northwest central Indiana. Expect
this to traverse the northern fringe of the area this afternoon and
be done with by 00Z, so will carry no precip chances this evening. A
stray drop or two would not be entirely shocking, but with the
column rapidly drying from aloft, do not feel pops are merited.

Stratocumulus will gradually erode and dissipate during the evening
hours with mostly clear skies expected by late tonight. Convective
temperatures may be reachable tomorrow, with some fair weather
cumulus possible as a secondary upper low slides southeastward
through the northern and eastern Great Lakes, but despite some steep
low level lapse rates, a general lack of moisture should prevent any
precipitation extending this far down into the area. Conditions will
likely be a bit breezy however, with gusts into the 20-30KT range
across the area tomorrow, highest to the northeast, thanks in part
to the aforementioned steep lapse rates and good mixing.

Dry weather and clearing skies can be expected Friday night as the
surface high slides directly overhead.

Last night's ample rainfall will prevent any fire weather issues
tomorrow despite good wind and mixing promoting afternoon RH values
dropping well into the 30s in spots.

Given anticipated sky cover conditions, blend temperatures look
pretty spot on throughout the short term. Expect a fairly wide range
of temperatures from northeast to southwest across the area tomorrow
afternoon as a backdoor cold front slides into the area with the
upper low pushing through the Great Lakes.

&&

.Long Term...(Saturday through Thursday)
Issued at 251 PM EDT Thu Apr 29 2021

Active spring weather pattern setting up for Saturday through
Thursday as several passing systems will impact Central Indiana.

Saturday will start with dry weather as models indicate weak ridging
in place across the country along with NW flow in place across
Indiana. An upper low is seen on Saturday morning over TX...but that
should be far enough off to the southwest to not impact Central
Indiana until Sunday and Sunday Night. Meanwhile surface high
pressure over the southeastern United States will allow for a
westerly flow of warm air advection. Thus will trend toward a dry
forecast with warmer temps.

On Sunday into Monday the models eject the upper low over TX
northeast...allowing it to become involved with the flow aloft. This
will result in SW flow aloft on Sunday before a slightly negatively
tilted trough arrives in Indiana on Monday...before departing by
Monday night. Mid level moisture fields suggest higher RHs arriving
ahead of the trough by Sunday afternoon and persisting through
Monday morning with the arrival of the upper trough axis. Thus will
at least include some pops from Sunday afternoon through late Monday
morning for now.

Aloft on Tuesday and Wednesday another weak but broad trough is
shown to be residing through the plains and into the Ohio Valley. On
Tuesday...little to no upper support appears present but residual
moisture from the previous system appears to be lingering. By
Tuesday night...a short wave within the flow is depicted to be
arriving...providing better chances for forcing and precipitation.
Will include chances for pops then. This wave looks to exit area on
Wednesday morning as an associated surface cold front exits to the
southeast and high pressure builds across the area for Thursday.
Thus for the moment...dry weather by Wednesday afternoon through
Thursday.

.Aviation...(18Z TAF Issuance)
Issued at 110 PM EDT Thu Apr 29 2021

IMPACTS:
* Borderline IFR conditions gradually improving to widespread MVFR
  through the afternoon, with VFR returning this evening.

* Winds 310-330 degrees through the early evening at 10-15KT gusting
  18-21KT.

* Gusts return late in the period (late morning Friday).

DISCUSSION: A cold front continues to exit the area this afternoon.
Vast majority of the precipitation has exited the area with it,
although there is a band of weak showers associated with the
trailing upper trough that may impact primarily LAF in the first few
hours of the period. Ceilings have been mainly IFR this morning but
are starting to improve to low end MVFR. Will likely ride the
borderline for the next few hours before improvement to widespread
MVFR and then a return to VFR by this evening, with VFR conditions
continuing through the rest of the period. Winds this afternoon in
the wake of the front will be northwesterly and breezy, with
sustained winds as high as 15KT and gusts into the low 20KT range.
This may cause some impacts to IND configuration through the
afternoon, although winds should weaken during the evening and allow
a return to normal for overnight traffic. Gusts will return late in
the period on what should be a breezy but more mild/pleasant day
Friday.
