.SHORT TERM...(This Evening through Saturday)
Cold air was spreading across the Ozarks Region this afternoon as
north breezes were gusting up to 30 mph at times.
This airmass originated from northern Canada, and will create a
hard freeze tonight into Saturday morning. Temperatures will fall
into the low to mid 20s, under clear skies and light winds.
Despite the return of southerly winds and sunshine on Saturday,
temperatures will struggle to warm out of the 40s in most
locations. Readings in the 50s are possible near Joplin and
No rain possible through Saturday.
.LONG TERM...(Saturday Night through Friday)
Showers and thunderstorms return to the Ozarks Region by Monday.
Models are in good agreement with the gradual approach of a
positively tilted long wave trough. This feature will force a
large band of convection from Texas up into the Great Lakes.
Widespread rainfall amounts will range from one to two inches
Monday through Tuesday night.
Models have sped up the passage of this wave, suggesting rain will
end northwest to southeast Tuesday into Tuesday night.
Beyond Tuesday night, the ECMWF and GFS diverge in handling an
upper level cutoff wave over Texas. The GFS progresses it across
the deep south, leaving the Ozarks Region dry. The ECMWF pulls it
north and creates a pattern for rain showers.
