Area Forecast Discussion
National Weather Service Springfield MO
526 PM CST Fri Jan 19 2018


.SHORT TERM...(This evening through Saturday)
Issued at 244 PM CST Fri Jan 19 2018

Surface high pressure is located across the Gulf Coast states this
afternoon as an area of low pressure is located across the western
Plains. This has resulted in southerly winds developing across
the area. Southerly winds will gust over 20mph at times this
afternoon into Saturday. A warmer air mass is spreading into the
area as temperatures this afternoon are currently in the lower to
middle 50s.

The southerly winds will usher in an increase in low level
moisture tonight into Saturday. The gusty winds should result more
in the way of low level stratus clouds developing tonight into
Saturday. The increasing clouds, southerly winds, and warmer air
mass will keep lows in the middle 30s to the lower 40s tonight.
Highs on Saturday will warm into the middle to upper 50s under
mostly cloudy skies.

.LONG TERM...(Saturday Night through Friday)
Issued at 244 PM CST Fri Jan 19 2018

The upper level low and surface low will push across the Plains
Sunday then across the region Sunday night allowing a cold front
to sweep across the area Sunday evening/night. Some scattered light
rain or drizzle will be possible Saturday night into Sunday as
increase moisture continues to spread north into the area ahead of
the system. Lows on Saturday night will remain in the 40s as
highs in the 60s are expected Sunday. Gusty southerly wind gusts
around 30mph will occur Sunday as the pressure gradient tightens
across the region ahead of the approaching area of surface low

Showers and a few thunderstorms will develop across the area as
the front and system tracks across the region. The better
coverage/higher rainfall amounts will generally occur east of
Highway 65 and south of I-44 but the entire area will likely see
some at least some light rain from this system. Locations across
south central Missouri could see up to an inch of rainfall with
this system as amounts decrease to the west and north.

Shear will increase across the area as the system approaches and
moves through the area. A few strong to marginally severe storms
with wind gusts being the main risk will be possible but over all
instability will be weak limited the overall severe risk. If more
instability can develop the strong to severe potential would be a
little better.

Gusty west to northwest winds will develop behind the front on
Monday with gust around 40mph expected. A cooler air mass will
spread into the area behind the front but will not be as cold as
past air mass over the last several weeks. Highs in the 40s and
lows in the upper 20s/lower 30s can be expected each day through
much of next week.
