Area Forecast Discussion
National Weather Service Sioux Falls SD
337 AM CDT Wed Oct 12 2016
.SHORT TERM...(Today and Tonight)
Issued at 337 AM CDT Wed Oct 12 2016
Upper level wave pivoting through the area with much drier air
filtering in behind. Scattered light rain showers will be likely
through about mid morning, but the threat will shift south and east
of the area by then. Cloud cover will diminish through the day but
with a north wind of 10 to 20 mph and high temperatures only from
the mid 40s to lower 50s it will feel pretty chilly outside.
High pressure will fill into the area tonight bringing light winds
to much of the area. Thus a freeze warning has been issued for the
entire county warning area. Locations along and west of the James
River Valley may not get quite as cold or see quite as much frost as
a southerly gradient increases after midnight and should allow winds
to increase to 5 to 10 mph. East of the James River and especially
across parts of northwest Iowa winds will remain light all night
andn these locations will see the highest threat for a killing freeze
and widespread frost. Aiming for lows in the mid 20s in lower spots
across northwest Iowa to 30 to 35 in central SD.
.LONG TERM...(Thursday through Tuesday)
Issued at 337 AM CDT Wed Oct 12 2016
After a cold start on Thursday, temperatures will rebound Thursday
into Friday as southerly flow increases ahead of a trough that works
through the region on Saturday. Have raised winds ahead of the
trough on Saturday. Temperatures on Saturday are tricky as they will
be conditional on how much sunshine will be able to reach the
surface. Appears as though there may be a fair amount of clouds
around, so have lowered highs slightly. With cold frontal passage,
have the potential for shower and thunderstorms across southwest
Minnesota into northwest Iowa. Precipitable water values ahead of
the front exceed 1", but with expected storm motion near 40 -45
knots, am not expecting a lot of precipitation at any particular
location.
Surface ridge builds into the region Saturday night into Sunday
morning, however modest southerly flow develops on Sunday shifts
through the area Sunday night. Could see some shower activity in
the east with this feature.
The feature that shifts through the area Sunday night lifts back to
the north as a warm front on Monday into Monday night keeping the
chance of unsettled weather around.
Cooler and drier conditions are expected Tuesday into Wednesday with
near seasonal temperatures.
&&
.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1027 PM CDT Tue Oct 11 2016
Light rain will gradually build back into the area overnight as
mid-level forcing moves through. Ceilings along and east of I-29
will bounce between MVFR to VFR at times as a layer of dry air
moves through the area. Further west, KHON may have also bounce
between VFR and high MVFR ceilings through daybreak.
Any precipitation tonight should remain on the light side, moving
east of the area after 14Z. Ceilings will gradually lift through
the morning, with clear skies and light winds by the early
evening.
