AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
332 PM CDT Thu Apr 9 2015
...Potential for Severe Storms into Early This Evening...
.MESOSCALE DISCUSSION...
Issued at 232 PM CDT THU APR 9 2015
Cold front will continue to push steadily to the east across the
area this afternoon into this evening. A cap remains in place
ahead of the front, but with lift from the cold front and height
falls with the associated upper level low, the cap is weakening
and storms are beginning to develop along the front.
Storms are currently mutilcelluar in nature and will not pose a
large severe risk over the next hour or so but a few of the
stronger storms could still be cable of hail to the size of
quarters and winds in excess of 50 mph with these storms generally
west of Highway 65.
As the cold front continues to march east and height falls and
large scale lift continue to over spread the area, still expecting
a line or line segments to develop along the front late this
afternoon into early this evening generally east of Highway 65.
The main risk with these storms will be winds to 60 mph. This will
not be a widespread risk and not everyone will see severe weather
this afternoon and evening but the potential will exist across any
locations that are affected by a well developed line segment. The
hail risk will remain more marginal in nature with quarters
possible with a few of the stronger updrafts. The tornado risk
will also be limited in nature, associated with well developed
line segments that can surge to the east across the eastern
Ozarks.
&&
.SHORT TERM...(This Evening through Friday)
Issued at 320 PM CDT THU APR 9 2015
The upper trough and associated cold front will swing to the east
of the area tonight. Thunderstorms will end across far south
central Missouri and the eastern Ozarks by mid evening.
Gusty northwesterly winds will persist behind the front this evening
before subsiding overnight. Surface high pressure will build
across the Ozarks Friday providing a tranquil spring weather day.
.LONG TERM...(Friday Night through Thursday)
Issued at 320 PM CDT THU APR 9 2015
Surface high pressure will slide to the east into the Ohio River
Valley Saturday as the upper flow goes zonal within a split flow
regime. This will lead to an extended period of unsettled weather.
An initial disturbance will approach Saturday night while isentropic
upglide develops. This will lead to the development of elevated
convection across the Plains that will spread eastward into Missouri
later Saturday night into Sunday morning.
Looks to be lull in precipitation chances Sunday afternoon before
rainfall potential increases again Sunday night as a northern
stream shortwave tracks across the northern Plains and an
associated front drops southward into the region.
This front will stall just to south Monday before lifting north as a
warm front Tuesday or Wednesday in advance of a southern stream
shortwave trough.
Meanwhile a deeper long wave trough will evolve over the Plains mid
to late week. A deep southerly fetch in advance of this system will
maintain the chance for additional rainfall into at least Thursday.
Medium range models suggest this trough could close off over the
central U.S. resulting in cooler and potentially showery weather
heading into next weekend.
Overall it looks like several days of unsettled spring weather.
However the potential for severe weather appears to be low at this
time.
&&
.AVIATION...(For the 12Z TAFS through 12Z Friday Morning)
Pilots can expect windy conditions and a wind shift this afternoon
as a cold front pushes across the region. Thunderstorms will
develop along the front that could impact the Springfield and
Joplin terminals. Areas of MVFR ceilings could develop where
storms develop as well as a time behind the front.
Southwesterly surface winds will gusts to around 35 kts ahead of
the front before shifting to northwest. Winds will decrease this
evening.
