National Weather Service Springfield MO
1120 PM CST Tue Nov 21 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 1217 PM CST Tue Nov 21 2017

A dry sfc cold front continues to move through MO. Extensive mid
and high level clouds will clear this afternoon as an upper level
shortwave axis moves off to the east. A very dry Canadian air
mass will move in tonight. The sfc high will shift southeast
through our area Wed afternoon/evening.

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 1230 PM CST Tue Nov 21 2017

Quiet weather is expected Thanksgiving and throughout the holiday
weekend. A prolonged dry period will worsen drought conditions
over southern MO.

Through Fri: Upper level nw flow will keep the weather quiet this
week. A shortwave moving quickly through the northern Rockies and
into the Midwest will support another dry sfc cold frontal
passage Fri evening. We will see a warming trend Thu-Fri with
highs well above normal Fri ahead of the front. Southwest winds on
Friday will pick up with an uptick in fire weather concerns. Will

Sat-Sunday: Sfc high pressure behind the front will move through
this weekend.

Mon-Tue: South winds will again develop as the sfc high shifts
east and another shortwave and sfc front approach. This next
upper system looks a little stronger with more amplitude as it
digs into the Rockies. This will slow the front down, but even
then a lag in modified Gulf moisture return will limit significant
rain chances with the frontal passage passage. There has been a
small/minor uptick in qpf in recent global models for late Tue,
at least over the eastern cwfa.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1051 PM CST Tue Nov 21 2017

Surface high pressure will build into the area through Wednesday
providing VFR conditions. Winds will subside overnight with light
surface winds expected Wednesday.
