...UPDATE TO SYNOPSIS...

.SYNOPSIS...
Issued at 932 AM CDT Mon May 23 2016

WV imagery indicates a southwest flow aloft prevailing across the
Western High Plains downstream of an elongated upper level trough
set up across the Intermountain West. Meanwhile, an embedded
shortwave within the broader scale trough is digging southeast
along the Pacific Coast of northern California. Near the surface,
a weak frontal boundary extending from north central Kansas
southwestward into southwest Kansas, is advancing slowly east-
southeast.

.SHORT TERM...(Today and tonight)
Issued at 352 AM CDT Mon May 23 2016

A cold front is advancing across central NE into northern KS, which
will reach the central sections of our forecast area mid morning.
Not seeing significant indications any instability will be realized
once this front arrives in our area, and by late morning, the
surface winds begin to veer and remain light northeasterly until
late day.

The main convective threat will be supercells either initiating or
moving north out of Oklahoma focused within the main higher
moisture/surface dew point axis ahead of the surface dryline.
However this may become complicated by the true southward extent of
the aforementioned cold front position.  Another area of interest
will be behind the washed out cold front in the increasingly
easterly upslope surface flow along the KS/CO line where the NAM is
insistent on isolated supercell development with potential for giant
hail, and much less of a tornado threat. Threat ares may need to be
adjusted later today as the convective models refine the best
locations for initiation. Still, low to upper 80s look agreed upon
by numerical models for this aftenroon`s highs

.LONG TERM...(Tuesday through Sunday)
Issued at 352 AM CDT Mon May 23 2016

Little changes in the overall synoptic pattern in the coming days.
The models have been consistent will keeping Wednesday the likeliest
day to be dry and quite (no convection at least), however the rest
of the forecast looks fairly active with at least peak heating
dryline storms and waves exiting the the quasi-stationary western
upper trough. The warming trend will continue into mid week with
90s almost a certainty by wednesday. More clouds and precipitationmay
cool temperatures by late week with models showing a strong
shortwave into the plains. Overnight lows remain somewhat mild in
the mid to upper 50s through the period.

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 635 AM CDT Mon May 23 2016

A cold front that extended from eastern Nebraska into southeast
Colorado early today will become stationary from southeast
Nebraska to the northern Texas Panhandle by 15Z but will retreat
north as a warm front tonight. The front should reach GCK by 12Z
and DDC between 13Z and 14Z. Patchy stratus with local ceilings
near 020 will exist south of the front, and widespread ceilings
025-035 should prevail behind the front. Scattered showers and
thunderstorms can be expected in the HYS vicinity through 13Z.
Scattered thunderstorms likely will develop along the stationary
front late this afternoon, and cluster of thunderstorms is likely
to form in northern Kansas after midnight.

An upper level low will remain nearly stationary in southern
Saskatchewan today, and another low will dig south along the west
coast into southern California by Wednesday morning. An upper
level trough in northwest Arizona early today will move rapidly
into western Nebraska by sunset. Low level winds at TAF locations
will become north to northeast 10 to 15 kts following frontal
passage this morning. Surface pressures will fall in northeast
Colorado this afternoon, and low level winds will become light and
somewhat variable by 20Z.
