Great Lakes.


.SHORT TERM...(This evening through Monday)
Issued at 304 PM CDT Sun Jun 18 2017

Northern Plains in fast northwest flow. Weak disturbance to the
northwest as seen in WV and on 88d returns. Light showers associated
with this disturbance that will move across western Nebraska this
evening. Have included slight chance of light rainshowers as several
of the short term solutions give enough lift with this disturbance
to squeeze out some light rain or sprinkles with drier lower layers.
Got pretty cool last night over western Nebraska with a low of 38 at
Alliance and mid 40s over much of western Nebraska. With cloud cover
temperatures should hold in the low 50s east and southwest and the
upper 40s northwest. Secondary wave rotates around Great Lakes low
diving across northern plains on Monday with temperatures similar to
todays highs in the 70s north and the low 80s south with cold air
advection continuing over north central Nebraska.

.LONG TERM...(Monday night through Sunday)
Issued at 304 PM CDT Sun Jun 18 2017

Desert Southwest ridge begins to move east Tuesday as Great Lakes
low heads into the Hudson Bay area. 80s and 90s return with
southerly flow on the backside of the surface high. Dew points in
the 60s. Wednesday similar but warmer with most of western Nebraska
in the 90s. A cold front will move across western Nebraska Wednesday
evening with thunderstorms along the front as it moves southeast.
Daytime highs will be realized before the front moves through with
highs in the 80s and 90s. Stronger wave drops into the northern
plains Friday night into Saturday with a stationary boundary across
southern Nebraska that will be the focus for thunderstorm
development. Temperatures falling back into the 70s Friday
through Sunday.


.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1130 PM CDT Sun Jun 18 2017

Local radar display shows unorganized isolated/scattered light
rain showers moving southeast and affecting portions of the
southern Sandhills and southwest NEB. These showers continue to
regenerate and very light rainfall is expected (trace to 0.05").
These showers are expected to continue through the small hours.
Elsewhere, showers are moving southward from south central SD,
however, the impacts from these showers are anticipated to be less
given their areal coverage. Otherwise, VFR ceilings are in place.
Clouds will persist across much of the local forecast area
tonight with improvement coming late tonight into early tomorrow
morning across western NEB.

Light winds will prevail rest of tonight with winds then
increasing tomorrow. Highest gusts expected over north central
NEB with peak gusts up to 25 MPH, elsewhere occasional gusts to
15-20 MPH.
