Area Forecast Discussion
National Weather Service Goodland KS
Issued by National Weather Service Dodge City KS
204 PM MDT Thu Apr 27 2023

.SHORT TERM...(This evening through Friday)
Issued at 203 PM MDT Thu Apr 27 2023

This mid-afternoon water vapor loop and RAP analysis overlay
revealed quite the impressive shortwave trough diving south within
the broader longwave trough pattern. The mid tropospheric potential
vorticity anomaly was centered across central Montana early in the
afternoon with impressive downstream upward vertical motion ahead of
the storm moving into eastern Wyoming and western Nebraska. This
enhanced region of lift continued to draw closer to the tri-state
region, and afternoon Day Cloud Phase Distinction RGB imagery showed
a growing boundary layer cumulus field across northeastern Colorado
into far northwest Kansas and adjacent far southwest Nebraska.

The HRRR model seems to have a pretty good handle on this storm
system, and there has been run-to-run continuity of surface-based
shower and thunderstorm development across the northwest half of the
the GLD CWA after 21Z. Boundary layer moisture was limited, however
500/700mb temperatures of -20/0C along with surface temperatures
warming to the lower 70s resulted in deep layer, steep lapse rates
and SBCAPE increasing to around 500 to 700 J/kg despite surface
dewpoints in the mid to upper 30s degF. Thus, the greatest severe
weather risk will be damaging straight line winds with the deepest
convective plume late afternoon/early this evening. The threat of 60-
65 mph peak wind gusts has been messaged given this latest forecast
thinking. As the strongest forcing for ascent moves across the tri-
state region this evening, the HRRR suggests the leading axis of
convection may form a loosely organized multi-cell line cluster as a
modest cold pool develops.

It will be difficult to differentiate an initial convective cold
pool from the actual synoptic cold front itself, but there may be a
bit of a separation between the two meteorological features.
Regardless, the synoptic cold front will be pushing south quickly
later on tonight. By that time, the axis of greatest lift and
subsequent numerous showers will push south of our region down into
southeastern Colorado and southwestern Kansas. North-northwest winds
behind the synoptic cold front will likely be 25 to 35 mph sustained
with gusts well in excess of 40 mph at times...through at least the
first half of the day Friday as northwest Kansas and surrounding
region remains in the fairly tight MSLP gradient as the upper level
cyclone continues to move south-southeast down into New Mexico and
the Texas Panhandle.

Back to the precipitation forecast, the official forecast will
reflect a precipitation type changeover to a wet snow before ending
over the higher elevation areas of the GLD forecast area
(western/southwestern half, particularly in vicinity of the Palmer
Divide), but any snow before ending will likely be fleeting with
essentially no accumulation expected.

.LONG TERM...(Friday night through Thursday)
Issued at 203 PM MDT Thu Apr 27 2023

Over the weekend, the northwest flow pattern on the longwave scale
will continue across much of the western Great Plains and adjacent
Rockies as a deep gyre becomes established across the Great Lakes
region. Another deep trough will develop along the West Coast early
next week with another deep upper low likely to develop out of the
trough out west. The hemispheric scale regime looks quite blocky
with the tri-state region in between these large gyres with very
little in the way of sensible weather to affect the region. This
will likely result in fairly light winds for the most part and
temperatures quite seasonable with the warmest air mass shunted well
to the south through at least Tuesday. The latest models suggest the
Great Lakes region and West Coast gyres dissolving with more
westerly momentum crossing the Rockies mid to late next week. Mid
next week and beyond, the forecast becomes far more uncertain in
terms of temperature forecasting and (severe?) convection.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1056 AM MDT Thu Apr 27 2023

The onset of this new TAF period will be fairly good, however
aviation weather conditions will deteriorate by late afternoon as
an initial band of showers and thunderstorms develop out ahead of
an advancing cold front. This convection is expected to impact
both GLD and MCK terminals with thunder in vicinity for a couple
hours late afternoon/early evening. Winds will likely be very
strong in vicinity of showers/storms with gusts 45 to 50 knots
possible. Thereafter the remainder of the night, scattered to
numerous showers will continue, however probability of thunder
will decrease later in into the evening as lower level instability
decreases. MVFR flight category is expected as stratus clouds move
in behind the front late tonight with forecast ceiling 1500 to
2500 feet BKN-OVC. North-northwest winds will remain quite strong
20 to 25 knots sustained, gusting 40+ knots at times through the
end of this TAF period.
