.SHORT TERM...(Today through Saturday)
Issued at 334 AM CST Thu Nov 16 2017

Satl imagery this morning was showing near zonal flow extending
across the CONUS. At the surface...a wedge of high pressure was
situated across the Plains.

Tonight...increasing isentropic upglide coincident to boundary layer
moisture axis extending from eastern KS into western IA. Sounding
profiles are more conducive for light drizzle initially Friday
morning and mainly over the IA CWA where condensation pressure
deficits will be least. Dry then during the afternoon hours. A
cold front is progged to drop into the northern CWA Friday
evening. Soundings at that time indicate the column will be
saturated enough to support rain. Precip activity...possible
rain/snow mix at times...expands then over the rest of the CWA
through Saturday morning. Given the amount of moisture feeding
into the region...a few locations might well rainfall amounts of a
tenth of an inch or so. Dry then Saturday/Saturday evening.

.LONG TERM...(Saturday night through Wednesday)
Issued at 334 AM CST Thu Nov 16 2017

Only minor tweaks applied to the extended periods as medium range
models continue to show a progressive pattern well into next week
with no significant systems moving through to induce precip.
Otherwise...looking highs at or just above normal ranging from the
upper 40s to low 50s. Lows also just above normal ranging from
the mid 20s to low 30s.
