Area Forecast Discussion
National Weather Service Springfield MO
320 PM CDT Wed Jun 30 2021
.SHORT TERM...(This evening through Thursday)
Issued at 307 PM CDT Wed Jun 30 2021
More widespread convection this afternoon associated with a
shortwave trough moving through the area. High precipitable water
values continue to bring a very heavy rainfall threat and flooding
threat where training convection occurs. Could also see some
strong to possibly severe storms into this evening with winds the
primary hazard.
Should see a lull for a few hours late this evening into early
tonight before the upper trough and surface cold front move in
late tonight into Thursday. Another round of showers and storms
with heavy rainfall will be likely, but not expecting any severe
threat this time. Precip will end from north to south in the later
afternoon into evening hours.
.LONG TERM...(Thursday Night through Wednesday)
Issued at 307 PM CDT Wed Jun 30 2021
Forecast is dry for the most part (perhaps some showers over the
southern CWA on Friday) through Friday through early next week.
Humidity will be lower with highs in the low to mid 80s and lows
in the mid 50s to 70s, making for a pleasant Independence Day
weekend.
A more active pattern is possible toward the last half of next
week, but confidence is limited.
&&
.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1230 PM CDT Wed Jun 30 2021
Scattered showers and thunderstorms will continue through much of
the day. For the most part should see VFR conditions with MVFR or
lower conditions under convection.
Less coverage of convection is expected from late this evening
into the early overnight hours before coverage increases again
later tonight into Thursday. A cold front will move through the
area Thursday, possibly resulting in lowered ceilings to IFR.
