...Updated Long Term...

.SHORT TERM...(This afternoon through Friday night)
Issued at 1200 PM CST Thu Mar 4 2021

Closed cyclone tracking across southern Colorado right on schedule
at midday, with the associated surface low organizing over SE
Colorado. Forcing for ascent and diffluence aloft continue to
increase at midday, and southeast winds will continue to increase
for the next several hours, gusting over 30 mph. Paltry moisture
advection continues, with dewpoints now into the upper 30s. There
is not much moisture to tap upstream in Oklahoma; only expecting
low to mid 40s into SW Kansas by late afternoon and evening.
Additional moistening is ongoing from aloft, with widespread virga
already present visually and on radar. 12z NAM is focusing its
instability axis (MU CAPE of 500-1000 J/kg) from roughly the Dodge
City vicinity to the Red Hills by early this evening. This is
actually a very favorable setup for severe convection, given the
diurnal timing, lift/forcing, and shear....minus the needed
moisture and instability. Some strong to marginally severe low
topped storms/supercells are plausible this afternoon and evening,
as mid level cold advection continues over minimal boundary layer
moisture. Marginal hail (quarters or less) and wind gusts (< 60
mph) are possible. Measurable rain will be scattered around with
this activity, but confidence on the widespread beneficial
rainfall remains focused overnight, in the deformation zone north
of the southeast-digging mid level cyclone as it tracks into
western Oklahoma by sunrise Friday. Storm total QPF grids still
show a widespread 0.25-0.50 inch rainfall, and HRRR guidance
suggests most of this will fall between midnight and sunrise
Friday. Temperatures will remain well above freezing through this
entire event, and all precipitation will fall as rain. Winds will
be quite elevated and gusty from the northeast during the rain,
gusting over 30 mph. Temperatures sunrise Friday in the upper 30s
and lower 40s.

Light rain will linger across especially the southern zones for
the first few hours of Friday morning, with some more measurable
QPF mainly south of US 50. Widespread stratus and low clouds will
prevail Friday morning, but rapidly dissipate through the
afternoon amid strong subsidence. Models do show minimal cold
advection behind the departing trough, with a net decrease of
about -3C at 850 mb versus Thursday, but with plenty of early
March afternoon sun, mid to upper 50s are still expected. NE winds
of 15-25 mph will gradually weaken through late afternoon.

.LONG TERM...(Saturday through Thursday)
Issued at 135 PM CST Thu Mar 4 2021

The forecast is completely dry, Saturday through at least Tuesday.
Broad high pressure ridging will provide for a fantastic early
spring weekend. Afternoon temperatures will be recovering through
the 60s Saturday and Sunday, but the typical Kansas south winds of
20-30 mph will be blowing both afternoons. Still a bargain for
early March.

More of the same Monday, windy and warm, as flow aloft begins to
trend SWly in response to an expansive long wave trough arriving
in western North America. Afternoon temperatures in the lower 70s.

We continue to monitor Tuesday for potentially extreme danger of
wildfire spread. Model consensus places primary lee cyclone
(<996 mb) in the vicinity of SW Nebraska 6 pm Tuesday, with a
strong dryline trailing southward through the high plains.
Pressure gradients will be tight, with the tightest gradients
likely east of the dryline in central Kansas (850 mb winds of
45-50 kts). Still, locations behind the dryline will likely be
windier drier and warmer than any guidance, and will likely have
fire weather headlines Tuesday. Afternoon temperatures from the
NBM were near 80 and were accepted.

Synoptic pattern appears decidely springlike mid next week, with a
strong established dryline and convective potential given strong
SWly flow aloft. Expansive longwave trough across the Rockies
Wednesday will edge out onto the plains late Wednesday. Details
will waffle this far out, but the deterministic 12z ECMWF
currently suggests severe convection late Wednesday from the
southeast zones northeast through central/NE Kansas. This severe
potential will have to be watched closely, given a strong SWly jet
aloft and an open gulf, but climatology says most will be
southeast of SW Kansas. Cold frontal passage is expected Wednesday
night, followed by cooler/more stable air Thursday.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1028 AM CST Thu Mar 4 2021

High confidence that flight categories will degrade sharply this
TAF period, with ceilings falling to IFR and reduced visibility in
rain expected at all terminals. Increasing and lowering cloud
decks will continue this afternoon, with SE winds gusting to near
30 kts. Scattered rain showers and isolated thunderstorms are
expected to develop 18z Thu-00z Fri, at least in the vicinity of
all airports. The most degraded flight categories are expected
00-12z Fri, with widespread stratiform rain and stratus cigs
lowering to IFR. Visibility will be reduced to 3-4 sm at times.
Southeast winds this afternoon will back to northeast and remain
strong/gusty overnight, continuing to gust to near 30 kts at
GCK/DDC/LBL. Lingering light rain and stratus are expected 12-15z
Fri, followed by decreasing clouds and VFR by afternoon.
