Area Forecast Discussion
National Weather Service Hastings NE
1239 AM CDT Thu May 25 2017

.SHORT TERM...(This evening through Thursday)
Issued at 255 PM CDT Wed May 24 2017

For tonight, we will eventually get a low-level jet creeping in
from the west that could potentially give us a rogue shower,
especially north. Not enough instability for thunder the way it

There could be some leftover shower activity during the day on
Thursday, more likely in our north. But thunderstorm activity
could develop in the afternoon in the wake of a cold front.

.LONG TERM...(Thursday night through Wednesday)
Issued at 255 PM CDT Wed May 24 2017

Then Thursday night, we still expect the possibility of
thunderstorm activity developing over Colorado and moving into the
CWA, possibly forming into an MCS with the aid of a narrow
locally enhanced jet, that could swipe our southwest. There could
be enough elevated instability to give us a shot at some severe
weather with this.

A better chance of rain arrives by late Friday night as models
have consistently painted some decent qpf for our area within low-
amplitude flow, and could quite possibly carry over into Saturday
morning. Once again, there is enough instability/shear to have a
shot at some severe weather as convection to the west could once
again form into an MCS, although not the most favorable timing for
as much severe weather, this is our best shot at getting more
rain, and we could squeeze out a good half inch over much of our

Sunday is looking dry, but we could get a small chance of some
showers/thunderstorms within northwest flow on Memorial Day.

We will generally be near or just below normal for the next week.
