KEY MESSAGES
- THERE IS A SLIGHT RISK FOR SEVERE STORMS THIS AFTERNOON AND
EVENING FOR THE ENTIRE AREA. SUPERCELLS WILL BE POSSIBLE,
CAPABLE OF PRODUCING LARGE HAIL, DAMAGING WINDS AND BLOWING
DUST, AND PERHAPS A TORNADO.
- STORM CHANCES CONTINUE THROUGH MUCH OF THE WEEK. SEVERE
WEATHER IS POSSIBLE TUESDAY.
SHORT TERM /THROUGH TUESDAY NIGHT/
ISSUED AT 1231 PM MDT MON JUN 1 2026
CURRENT SATELLITE OBSERVATIONS HAVE A LARGE UPPER LOW OVER THE
NORTHWESTERN UNITED STATES WITH RIDGING OVER THE SOUTHERN UNITED
STATES. THE OBSERVATIONS ARE ALSO SHOWING CUMULUS CLOUDS FORMING
AROUND AND SOUTH OF HIGHWAY 40 IN NW KANSAS. THIS AREA IS OUR FIRST
AREA OF CONCERN FOR STORMS THIS AFTERNOON. WHILE THE EARLIER STORMS
DID USE UP SOME OF THE INSTABILITY, CLEARING SKIES AND CONTINUED LOW
LEVEL MOISTURE ADVECTION IS ALLOWING FOR DECENT RECOVERY. WITH THE
EARLIER OUTFLOW IN THE AREA, AM EXPECTING THIS AREA TO HAVE STORMS
DEVELOP AROUND 1-3PM MT. THIS IS JUST A BIT FASTER THAN PRIOR
FORECASTS, BUT NOT TOO MUCH OF A CHANGE. WE ARE STILL EXPECTING THE
STORMS TO DEVELOP AND MAKE THEIR WAY TO THE EAST/NORTHEAST. THE
ENVIRONMENT IS FORECAST TO HAVE PLENTY OF SHEAR WITH 0-6KM SHEAR
AROUND 40-50 KTS. WITH THE SHEAR AND MUCAPE AROUND 1500-3000 J/KG,
WE HAVE PLENTY OF SUPPORT FOR STORMS TO SUSTAIN THEMSELVES. THIS
DOES LEAD TO A CONCERN FOR SUPERCELLS WITH HAIL POTENTIALLY ABOVE 2
INCHES IN DIAMETER. OTHERWISE, STORMS THAT CLUSTER FAIRLY QUICKLY
SHOULD HAVE HAIL BETWEEN 0.5-2.0" WITH WIND GUSTS UP TO 70 MPH. THE
TORNADO THREAT IS FORECAST TO INITIALLY BE LOW WITH LCLS ABOVE 1500
METERS. BUT GIVEN A PERSISTENT ENOUGH STORM, LCLS SHOULD LOWER WITH
0-1KM SHEAR AROUND 10-20 KTS. THIS COULD ALLOW FOR A TORNADO TO FORM.
A SECONDARY LINE IS FORECAST TO FORM IN EASTERN COLORADO CLOSER TO
THE CENTER OF THE LOW AND ALONG THE PALMER DIVIDE. THESE STORMS
SHOULD PUSH STEADILY TO THE EAST NORTHEAST, MAINLY IMPACTING ALONG
AND NORTH OF I70 (THOUGH ALL OF EASTERN COLORADO HAS A CHANCE). THE
THREATS ARE FAIRLY SIMILAR TO THE OTHER STORMS AS THERE ISN'T
FORECAST TO BE MUCH OF A CHANGE IN THE ENVIRONMENT.
AS BOTH CLUSTERS PUSH EAST/NORTHEAST, THEY AREA FORECAST TO MOVE
INTO AN ENVIRONMENT WITH SLIGHTLY LESS INSTABILITY DUE TO THE EARLY
CLOUD COVER AND OUTFLOW FROM THE EARLIER STORMS. THAT BEING SAID,
THERE IS MORE MOISTURE FORECAST TO BE AVAILABLE. THIS MAY LEAD TO
THE CHANCES FOR SEVERE WEATHER DECREASING, BUT WILL ALSO HELP A LOW
CHANCE PERSIST THROUGH THE NIGHT AS LONG AS WE HAVE STORMS. THIS
WILL ALSO LEAD TO A CONCERN FOR FLASH FLOODING AS STORMS CONVERGE IN
THE NORTHEAST PART OF THE AREA, AND THEN POTENTIALLY REIGNITE ALONG
OUTFLOWS. THE OVERALL CHANCE IS AROUND 20% OR LESS AS STORMS WOULD
LIKELY HAVE TO STALL OVER AN AREA. WITH DOWNSHEAR VECTORS AROUND 40-
50 KTS, THIS DOESN'T SEE TOO LIKELY. BUT CLUSTERING/TRAINING OVER AN
AREA COULD LEAD TO 2-4 INCHES OF RAIN. OVERNIGHT STORMS CHANCES
SHOULD GENERALLY FAVOR NW KANSAS AND SW NEBRASKA. WITH THE STORMS
AND CLOUD COVER, TEMPERATURES SHOULD GENERALLY STAY IN THE 60S AND
70S. SOME FOG MAY ALSO OCCUR IN EASTERN COLORADO AND ADJACENT
COUNTIES AS LONG AS STORMS STAY TO THE EAST AND ALLOW FOR SOME
CLEARING AND COOLING.
FOR TOMORROW, SHOWERS AND STORMS COULD CONTINUE INTO THE MORNING AS
LONG AS OUTFLOW BOUNDARIES REMAIN IN THE AREA. BUT THEY SHOULD PUSH
OUT OF THE AREA LATER IN THE MORNING AS INSTABILITY DROPS DUE TO THE
PERSISTENT STORMS AND AS THE SURFACE LOW PUSHES A BIT MORE TO THE
WEST. THE UPPER LEVEL RIDGE IS ALSO FORECAST TO AMPLIFY A BIT MORE
INTO THE PLAINS AS THE UPPER TROUGH SHIFTS A BIT MORE TO THE NORTH.
WHILE THE PRECIP CHANCES MAY LOWER, THE CLOUD COVER IS FORECAST TO
BE FAIRLY THICK FOR MOST OF THE DAY, WHICH SHOULD KEEP TEMPERATURES
IN THE 70S AND 80S.
AS THE DAY GOES ON, THE UPPER TROUGH AXIS TO THE NORTHWEST IS
FORECAST TO SHIFT A BIT EASTWARD ALONG WITH THE SURFACE LOW. THIS
MAY BE JUST ENOUGH TO GET STORMS GOING AGAIN, THOUGH ANY PRIOR
ACTIVITY MAY STABILIZE THE AIR TOO MUCH. IF IT DOESN'T, IT LOOKS
LIKE STORMS SHOULD FIRE UP ALONG THE PALMER DIVIDE AGAIN AND MAYBE
CLOSE TO GREELEY COUNTY IF A SURFACE CONVERGENCE ZONE SETS UP. THE
MAIN DIFFERENCE FOR TOMORROW IS THAT THE FLOW AS A WHOLE IS FORECAST
TO BE WEAKER, LEADING TO LOWER SHEAR AND LOWER WIND GUST POTENTIAL.
THIS SHOULD LEAD TO MORE CLUSTERING STORMS THAT MAY STRUGGLE TO HOLD
TOGETHER. THE SEVERE HAZARDS SHOULD ALSO BE A LITTLE LOWER IN
INTENSITY, THOUGH AN ISOLATED STORM MAY BE ABLE TO STILL PRODUCE
VERY LARGE HAIL AND MAYBE A TORNADO. AS STORMS PROGRESS EAST, THE
INSTABILITY IS FORECAST TO LOWER WHICH SHOULD HAVE MOST STORMS
DISSIPATE OR BECOME SHOWERS. MAY STILL HAVE STORMS LINGER THROUGH
THE NIGHT IN OUR EASTERN AREAS IF THEY CAN KEEP FORMING ON OUTFLOW
BOUNDARIES. TEMPERATURES SHOULD REMAIN IN THE 60S AND 70S FOR MOST
OF THE NIGHT WITH THE CLOUD COVER AND LINGER PRECIPITATION.
LONG TERM /WEDNESDAY THROUGH MONDAY/
ISSUED AT 117 PM MDT SUN MAY 31 2026
FOR THE EXTENDED PERIOD OF THE WEEK, WEDNESDAY THERE IS A WEAK RIDGE
THAT IS SANDWICHED BETWEEN TWO LOWS. THE LOW PRESSURE SYSTEM TO THE
NORTHWEST OF THE RIDGE, WILL KICK OUT SOME SHORTWAVE DISTURBANCES
THAT WILL BRING PRECIPITATION CHANCES TO THE REGION. THEN THE UPPER
FLOW TRANSITIONS TO MORE ZONAL FLOW. AS NEXT WEEKEND APPROACHES, THE
UPPER PATTERN BEGINS TO CHANGE. THERE ARE SIGNS OF A TROUGH THAT
MOVES INTO THE AREA FROM THE PACIFIC NORTHWEST.
GUIDANCE HAS BEEN SHOWING THE HIGH TEMPERATURES TO BE IN THE MID 80S
TO LOW 90S FOR THE MAJORITY OF THIS PERIOD. THE LOWS ARE FORECAST TO
BE IN THE 50-60S RANGE. WINDS LOOK TO REMAIN RELATIVELY CALM AND
FROM THE SOUTH TO SOUTHEAST. THE ONLY OUTLIER IN THIS IS WEDNESDAY
WHERE TEMPERATURES HANGOUT IN THE MID TO LOW 80S. HOWEVER, THE LOWS
REMAIN IN THE 50 TO 60 RANGE.
AS FOR PRECIPITATION CHANCES, THE CWA IS IN THE TYPICAL AFTERNOON
SHOWER/STORM CHANCES IN THE AFTERNOON/EVENING. WEDNESDAY THROUGH
FRIDAY POPS ARE IN THE 20-70% RANGE. SATURDAY AND SUNDAY'S
PRECIPITATION CHANCES DECREASE TO 10-30%. EACH DAY IS CURRENTLY
FORECAST TO HAVE ATLEAST 1000 J/KG OF SFC CAPE WHICH WOULD SUPPORT
STORM DEVELOPMENT.
AS FOR SEVERE POTENTIAL, THERE IS NO STRONG SIGNAL FOR ANYTHING YET.
HOWEVER, DIFFERENT GUIDANCE OUTPUTS HAVE SUGGESTED THAT THE
SHORTWAVE DISTURBANCES COULD BE STRONGER. ALSO, MORE MOISTURE COULD
BE ADVECTED IN INCREASING MORE FUEL FOR STORMS.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1109 AM MDT MON JUN 1 2026
FOR KGLD & KMCK... VFR CONDITIONS ARE FORECAST THROUGH 09Z, BUT
STORM CHANCES ARE FORECAST TO INCREASE AS WE GET INTO THE LATE
AFTERNOON AND EVENING HOURS. THESE STORMS ARE LIKELY TO FORM
WEST AND SOUTH OF THE TERMINALS BEFORE MOVING OVER. SEVERE
WEATHER IS POSSIBLE WITH LARGE HAIL AND WIND GUSTS OF 50-60 KTS.
BLOWING DUST MAY ALSO DEVELOP AND REDUCE VISIBILITY TO A MILE AT
TIMES. KMCK HAS THE HIGHER CHANCES FOR STORMS AND MAY SEE THEM
FOR AN EXTENDED PERIOD AFTER 00Z. ONCE THE STORMS CLEAR,
CEILINGS ARE FORECAST TO LOWER TO AROUND OR BELOW 1000FT FOR THE
EARLY MORNING HOURS. IF STORMS OR SHOWERS REMAIN IN THE
VICINITY, CEILINGS MAY STAY CLOSER TO 2500FT OR MORE. THE PRECIP
AND LOW CLOUDS SHOULD ALL BE CLEARING BY 15Z.
