Area Forecast Discussion
National Weather Service Omaha/Valley NE
127 PM CDT Mon May 29 2017

.SHORT TERM...(Today through Wednesday)
Issued at 227 AM CDT Mon May 29 2017

Upper low continues to spin across the western Great Lakes. First
vort lobe is moving through the area now and did trigger a few
sprinkles in northeast NE earlier this morning, but additional
moisture is extremely limited as the vort lobe moves south of the
area. The next lobe rotating around the low could help trigger
isolated showers today across the northern Plains/upper
Mississippi River Valley, in response to the cool temps aloft and
very steep lapse rates. These showers could approach northeast NE
and northwest IA this afternoon/early evening, but very doubtful
anything would be be heavier enough to measure, and will just
mention sprinkles. Otherwise, it will be another breezy day with
increasing winds and highs from 70-78 as a reinforcing cool front
continues to settle southward.

The frontal boundary may eventually wash out near the KS/NE
border. This boundary may still be somewhat present on Tuesday,
with spotter showers possible along it, but possibly just to our
south across KS and MO. Highs Tuesday again from 72 to 78.

Dry weather continues into Wednesday with surface high pressure
across the mid Missouri Valley region. Highs Wednesday a little
warmer 75 to 80.

.LONG TERM...(Wednesday night through Sunday)
Issued at 227 AM CDT Mon May 29 2017

Rain chances return Wednesday night as moisture and instability
return on southerly flow and a strengthening low level jet. Rain
chances linger Thursday morning and lift northward through the
area through the daytime. Thursday night and Friday look dry with
precip chances both north and south of the area. Thursday and
Friday should be warm with highs boosting into the mid 80s on
breezy southerly flow. Another frontal boundary moving into the
region Saturday, which brings precip chances back, along with
slightly cooler temperatures, then dry for Sunday.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 122 PM CDT Mon May 29 2017
