Hail in Nebraska, May 29, 2022

Area Forecast Discussion
National Weather Service Goodland KS
1029 PM MDT Sun May 29 2022

.SHORT TERM...(This evening through Tuesday)
Issued at 326 PM MDT Sun May 29 2022

This Afternoon-Tonight... As of 1940Z, the Tri-State area is sitting
beneath a surface high, which is pushing the cloud deck observed
across the area this morning and the frontal boundary to the
east/northeast. Along the Front range, a surface low is surrounding
the high to the west and south with rain and thunderstorms moving
over the Denver metro to WY state line corridor of I-25. These
storms and the low are expected to continue east-northeast and
remain mainly north of our forecast area. Should any storms move
into Yuma or along the Nebraska border, they are expected to remain
mainly sub-severe given the unfavorable amount of MLCAPE and the
amount of CIN. Lapse rates and shear are supportive of convection.
Over the course of the evening, a few storms could clip south into
the area mainly along and north of Hwy 36. Should storms enter the
area, hazards include up to 60 mph wind gusts and up to quarter size
hail. CAMs have been hinting at a second round of showers and sub-
severe storms overnight that could impact areas along and NW of a
line from Flagler, CO to McCook, NE. A few downbursts could be
possible with any strong updrafts tonight. Overnight lows are
forecast to be in the mid 40s to lower 60s.

Memorial Day... Cooler temperature are anticipated on Monday with
highs in the upper 60s to mid 80s. The trough axis will begin to
move over the area tomorrow with the low expected to be around the
SD/ND/MN borders and another low developing over the TX/OK
Panhandles. A few showers and storms from the overnight hours could
continue to the early afternoon hours tomorrow, with severe weather
not anticipated given the less than 500 J/kg of MLCAPE. Most of the
activity is expected to remain along the Nebraska border, moving
northeast. During the late morning, areas south of the interstate
are expected to dry out similar to today with RH values as low as 11
percent and westerly winds gusting up to 45 mph. After sunset, winds
are expected to shift to be out of the northwest/north-northwest.
Given the potential for several hours of critical fire weather
conditions, decided to upgrade the Fire Weather Watch for Cheyenne
County, Colorado to a Red Flag Warning. Outdoor burning is not
advised. Once the rain/storms clear out, dry conditions are
anticipated for the remainder of the day. Overnight lows are
forecast to fall into the 40s to mid 50s.

Tuesday... The area will be under southwest flow aloft as a broad
upper trough containing several areas of low pressure rotates
over the NW CONUS and into the Upper Midwest. Temperatures are
expected to continue cooling off with highs forecast to be in the
upper 60s to lower 80s and overnight lows in the 40s to around 50
degrees. Dry conditions are anticipated to stick around during the
day, with chances for precipitation and non-severe storms
increasing around sunset from west to east into the overnight
hours while a shortwave trough swings across the Great Basin.

.LONG TERM...(Wednesday through Sunday)
Issued at 109 PM MDT Sun May 29 2022

A short wave trough aloft moves out of the central Rockies and
over the central High Plains region during the day on Wednesday
and east of the region on Thursday. A cooler area of high pressure
pressure moves into the region at the surface Wednesday with
upslope conditions moistening the lower layers while the short
wave aloft assists in producing some embedded showers and
thunderstorms.

Thursday and Thursday night will remain mostly dry as high
pressure pushes further across the Plains states and the Ridge
over the Intermountain and Rocky Mountain regions flattens as
individual waves approach from the west and diurnally driven
convective activity over the Rockies produces vorticity maxes that
are carried east over the plains each evening for an active period
of showers and warmer temperatures through the end of the upcoming
week and into the weekend.

The lowest temperatures of this period are on Wednesday with
highs in the middle 50s to middle 60s and lows in the upper 30s to
middle 40s. by Saturday, highs will be back up into the 80-85
degree range.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1025 PM MDT Sun May 29 2022

VFR conditions are anticipated to prevail through the TAF
period.. with ceilings generally confined at/above 10-12 KFT AGL.
Isolated thunderstorms cannot be ruled out at either terminal on
Monday.. mainly during the morning (12-18Z). With widespread
convection nearby and upstream of the area (northeast CO and
western-central NE) overnight into Monday morning.. and a
deepening low pressure system anticipated to track northward from
western KS into central NE during the day.. confidence in wind
speed/direction are well below average. In general.. expect N to
NW winds at 15-20 knots overnight. Winds will back to the W
(anywhere from WNW to WSW) and increase to 15-25 knots several
hours after sunrise (~15Z).. further increasing to 20-30 knots
during the late morning. A period of strong westerly winds is
possible during the late morning and afternoon hours, particularly
at the GLD terminal.. where sustained winds could reach 25-35
knots with gusts to ~45 knots.. depending on the depth/extent of
vertical mixing.
