Area Forecast Discussion
National Weather Service Hastings NE
636 PM CDT Mon Sep 25 2017

.SHORT TERM...(This evening through Tuesday)
Issued at 401 PM CDT Mon Sep 25 2017

As expected, it`s been a cool, dreary day across the area, with
the main band of precipitation continuing to push east through
the CWA. Aloft, flow remains southwesterly, with satellite imagery
showing the main upper low spinning over WY. At the surface, we
remain north of the main frontal boundary, which extends from the
OK/TX panhandle regions northeastward into the western Great
Lakes, keeping winds out of the north around 10-15 MPH. The region
remains socked in with low level stratus, most under 1000ft, and
temperatures currently sit generally in the mid 50s.

Looking to the rest of the short term, models are in good
agreement showing the main upper level system continuing on a
northeastward track, ending up over the western Dakotas by 12Z
tomorrow and into southwestern Ontario by the end of the day. The
southward extending trough axis will continue to gradually swing
through the Plains, and though the main axis of precipitation is
shifting just of to our east-southeast, at least scattered
additional development will remain possible across the CWA through
tomorrow morning. Kept some lingering PoPs across the far
southeast in the 12-18Z period tomorrow, with the afternoon being
dry. At the surface, the main front continues pushing south, as
high pressure settles in from the north. Northerly winds will
continue, with speeds topping out around 10 MPH. Low level stratus
looks to linger across the area overnight and into at least part
of tomorrow, but lessening sky cover is expected from west to east
through the afternoon. High temperatures are forecast to be below
normal, topping out in the mid 50s.

.LONG TERM...(Tuesday night through Monday)
Issued at 401 PM CDT Mon Sep 25 2017

As we get into the middle/later portions of the work week, the
forecast remains dry. As today`s system continues pushing
northeast, the next system is digging south along the west
coast. By the time Wednesday morning rolls around, a closed low
has developed over the CA/AZ/NV border area. Shortwave ridging
develops over portions of the Plains, expected to keep things dry.
A blocking pattern sets up, at least briefly, across the west,
but as we get closer to Friday, the upper low starts making more
of a push northeast. Precipitation chances return to the forecast
Friday night and into the weekend as a more unsettled pattern sets
up, but there is plenty of differences between models, so
confidence isn`t high. Not expecting any big swings in
temperatures through the long term period, generally topping out
in the 70s.

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Tuesday)
Issued at 636 PM CDT Mon Sep 25 2017

IFR conditions are expected overnight at both terminals with low
stratus and some light showers possible. Northerly winds will
persist throughout the TAF period. IFR ceilings will lift to MVFR
in the morning before skies start to clear from west to east
during the afternoon hours.
