Area Forecast Discussion...UPDATED
National Weather Service Springfield MO
1217 PM CDT Thu Jun 17 2021

...18Z AVIATION UPDATE...

.MESOSCALE DISCUSSION...
Issued at 930 AM CDT Thu Jun 17 2021

Updated the morning/afternoon forecast to increase the potential
for precip a little more across areas east of Springfield. There
is also a signal for a few storms to become strong to severe given
the high instability and wind shear for storm organization.

Currently a MCV (remnant circulation from storms last night) was
located across west central Missouri. This was slowly drifting
south towards southwest Missouri. Another weak feature was a weak
shortwave across south central Missouri. 12Z SGF sounding showed
some capping with a conv temp of 94F and warming aloft, therefore
there is some question if the MCV can assist with enough lift for
thunderstorm development today, especially as warmer mid level
temps continue to move in during the day. Other thing of note
though was the strong instability and 0-6km shear of 35kts, which
is higher than expected and more than sufficient for storm
organization.

Current expectations are for isolated thunderstorms to develop
from now through this afternoon, mainly east of Springfield where
capping is less. ThetaE diffs of 25-30C would support isolated
damaging wind gusts of 50-60mph as well as hail to the size of
pennies in the more intense thunderstorms. We do expect most
storms to not reach severe levels however a few are possible,
especially in the Gainesville-West Plains-Alton region. We will
monitor areas further west closer to Springfield just in case
something can break the cap today.

Otherwise, mid/high level clouds may be our saving grace for temps
to get too out of control today, however it will likely still
reach the middle 90s across a large part of the area with heat
index values around 100 by afternoon.

&&

.SHORT TERM...(Today and tonight)
Issued at 246 AM CDT Thu Jun 17 2021

An MCV across NW MO is the point of focus in the near term. No
models are handling this convection well at all, making
it a challenge to forecast. A well established cold pool should
promote continued southward progress along the instability
gradient present across the area. Current indications suggest
best precipitation potential across the eastern CWA through the
morning hours. No severe weather is expected, but some stronger
storms may produce small hail and gusty winds. Cloud cover and any
precip should limit temperatures, so have started a downward
trend.

For tonight, expect partly cloud skies with lows in the low to mid
70s.

.LONG TERM...(Friday through Wednesday)
Issued at 246 AM CDT Thu Jun 17 2021

Sunny skies Friday will allow for highs in the mid to upper 90s
and max heat indices of 100-105.

A slightly cooler airmass overhead Saturday and Sunday will result
in highs in the low to mid 90s. A cold front looks to move through
Sunday night into Monday, resulting in a decent chance of
widespread rain (best rain chances in the forecast period).

The forecast looks dry for the most part Tuesday and Wednesday.
Expect highs in the 70s on Tuesday and in the low to mid 80s
Wednesday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1215 PM CDT Thu Jun 17 2021

VFR conditions are expected at the TAF sites with afternoon
cumulus expected. Can not rule out a shower or storm near BBG this
afternoon however confidence is too low to include. Winds will
remain out of the west to southwest around 10kts through the
period.
