OVERVIEW: SOUTHWEST FLOW ALOFT WILL PREVAIL IN THE LEE OF THE
CENTRAL ROCKIES.. ON THE WESTERN PERIPHERY OF AN UPPER LEVEL
RIDGE THAT EXTENDS NORTHEASTWARD FROM THE SOUTHERN PLAINS TO THE
CENTRAL MISSISSIPPI RIVER VALLEY AND UPPER MIDWEST. AN UPPER
LEVEL (~300 MB) SHORTWAVE, LOCATED IN NORTHEAST COLORADO AT 15
UTC THIS MORNING, WILL TRACK NE-NNE THROUGH WESTERN NEBRASKA
(AWAY FROM THE NWS GOODLAND COUNTY WARNING AREA) THIS AFTERNOON
AND DAKOTAS (TONIGHT). IN THE LOWER LEVELS, A WEAK SURFACE TO
850 MB TROUGH WAS PRESENT OVER EASTERN COLORADO AT 15 UTC..
MAINLY SOUTHEAST COLORADO (E.G. LA JUNTA, LAMAR, SPRINGFIELD).
FURTHER NORTH, WHERE LOW OVERCAST AND INTERMITTENT LIGHT SHOWERS
ARE INFLUENCING THE EVOLUTION OF LOW-LEVEL HEIGHT/WIND FIELDS,
A MODEST MESO-HIGH WAS PRESENT.
AN ATYPICALLY MOIST AIRMASS CHARACTERIZED BY SURFACE DEWPOINTS
~65-70F, 850 MB DEWPOINTS ~17-18C, NEAR MOIST-ADIABATIC (5.5 TO
6.0 C/KM) MID-LEVEL (700-500 MB) LAPSE RATES AND PRECIPITABLE
WATER VALUES ~1.50" TO 1.75" WILL PREVAIL OVER THE REGION TODAY.
WITHOUT AN ELEVATED MIXED LAYER, EXPECT LITTLE IN THE WAY OF
CONVECTIVE INHIBITION (CAP) THIS AFTERNOON. WEAK, MUDDLED
FORCING AND THE PRESENCE OF A FAIRLY UNIFORM/HOMOGENEOUS AIRMASS
(ASSISTED BY PERVASIVE MORNING STRATUS).. LEND LITTLE
CONFIDENCE WITH REGARD TO CONVECTIVE DEVELOPMENT, COVERAGE AND
EVOLUTION IN THE GOODLAND COUNTY WARNING AREA TODAY-TONIGHT, AS
ONE MIGHT SURMISE FROM SIMULATED REFLECTIVITY FORECASTS VIA
CURRENT AND RECENT RUNS OF CONVECTION ALLOWING GUIDANCE. WEAK
LOW-LEVEL/MID-LEVEL FLOW AND MODEST (15-30 KNOT) EFFECTIVE DEEP
LAYER SHEAR SUGGEST THAT CONVECTIVE ORGANIZATION, IF ANY, WOULD
LIKELY BE TRANSIENT IN NATURE.. AND THAT SEVERE WEATHER
POTENTIAL, IF ANY, WOULD LIKELY BE CONFINED TO BRIEF, LOCALIZED
WET DOWNBURSTS. PEOPLE ATTENDING OUTDOOR GATHERINGS FOR
INDEPENDENCE DAY ARE URGED TO KEEP AN EYE ON THE SKY, AND TO
CONSIDER THAT.. DANGEROUS CLOUD-TO-GROUND LIGHTNING CAN STRIKE
10 MILES AWAY FROM A THUNDERSTORM.
LONG TERM /SATURDAY THROUGH THURSDAY/
ISSUED AT 138 PM MDT WED JUL 2 2025
NOT MUCH CHANGE TO OVERALL FORECAST THINKING. A WASH, RINSE,
REPEAT PATTERN. THE MAINTENANCE OF THE MONSOONAL HIGH OVER THE
4-CORNERS REGION WILL INVOKE UPSLOPE FLOW ACROSS OUR AREA
TOWARDS THE FRONT RANGE OF THE ROCKIES. WITH ANY SHORTWAVE
ENERGY RIDING ALONG THE N-PERIPHERY OF THE MONSOONAL HIGH,
DIVING CYCLONICALLY E/SE ACROSS THE REGION WHICH WILL LIKELY
SEEN A MAINTENANCE OF HEAT AND HUMIDITY WITH THE S FLOW, WE
SHOULD SEE THE DEVELOPMENT OF THUNDERSTORMS THAT COULD POSE
POTENTIAL THREATS OF WIND, HAIL AND LOCALLY HEAVY RAIN. BUT
CONFIDENCE WITH REGARDS TO SPECIFICS REMAIN LOW AT THIS TIME.
SO, OVERALL, ON AND OFF AFTERNOON INTO EVENING THUNDERSTORM
CHANCES WITH HIGHS AROUND 90 AND LOWS AROUND 60 WITH BREEZY S
WINDS PREVAILING.
AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
ISSUED AT 506 AM MDT FRI JUL 4 2025
LOW CLOUDS CONTINUE TO OVERSPREAD THE AREA FROM THE SOUTH WITH
MVFR CEILINGS EXPECTED TO PREVAIL AT BOTH KGLD AND KMCK THROUGH
ABOUT 18Z BEFORE LIFTING. THIS AFTERNOON, SCATTERED
THUNDERSTORMS WILL DEVELOP AS A DISTURBANCE MOVES IN FROM
COLORADO. BRIEF DOWNPOURS AND GUSTY WINDS WILL ACCOMPANY ANY
THUNDERSTORM WHICH MOVES OVER A TERMINAL. STORMS WILL BECOME
MORE SCATTERED TONIGHT, BUT CANNOT RULE OUT IMPACTS AT EITHER
TERMINAL.
