SHORT TERM /THROUGH TONIGHT/
ISSUED AT 1245 PM MDT SAT JUL 5 2025
THE TRI-STATE AREA REMAINS SITUATED IN A WEAK FORCING REGIME,
ON THE NORTHERN PERIPHERY OF AN UPPER LEVEL RIDGE (ANCHORED OVER
NORTHERN MEXICO AND THE SOUTHERN PLAINS), IN W TO WSW FLOW
ALOFT. WEAK LOW-LEVEL AND MID-LEVEL FLOW, <= 15 KNOTS FROM THE
SURFACE TO 15 KFT AGL (UP TO ~500 MB) PERSIST, WITH STRONGER
FLOW CONFINED TO THE 200-300 MB LEVEL (25-35 KFT AGL). WHILE
WEAK FORCING CONTINUES TO FRUSTRATE CONVECTION ALLOWING
GUIDANCE, THERE APPEARS TO BE A GENERAL TREND/CONSENSUS THAT
SCATTERED CONVECTION DEVELOPING ALONG THE COLORADO FRONT RANGE
AND PALMER DIVIDE WILL PROGRESS EAST TOWARD THE CO-KS BORDER
(VIA MODEST WESTERLY STEERING FLOW) LATE THIS AFTERNOON AND
EVENING (~5-10 PM MDT). ISOLATED CONVECTIVE DEVELOPMENT COULD
OCCUR NEAR HIGHWAY 50 IN HAMILTON/KEARNY COUNTIES (PERHAPS
SOUTHERN GREELEY/WICHITA COUNTIES) ~20-22 UTC THIS AFTERNOON..
WHERE OBSERVATIONAL DATA INDICATES THAT MOISTURE POOLING IS
OCCURRING IN VICINITY OF A WEAK CONVERGENCE ZONE.. AND DIURNAL
CU WAS ALREADY PRESENT NEARBY TO THE WEST, OVER KIOWA/PROWERS
COUNTIES. A SEVERE STORM IS POSSIBLE ~20-22 UTC IF DEVELOPMENT
DOES OCCUR OVER SOUTHERN PORTIONS OF GREELEY/WICHITA COUNTIES,
THOUGH.. WITH RIGHT-MOVER MOTION FROM THE N AT ~25 KNOTS.. LEFT-
MOVER MOTION FROM THE W AT ~10 KNOTS AND THE MEAN WIND FROM THE
NW AT 15-20 KNOTS.. IT WOULD BE SHORT-LIVED IN NATURE (FOR THE
GOODLAND COUNTY WARNING AREA). IN CONTRAST TO YESTERDAY,
UNIMPEDED INSOLATION AND THE PRESENCE OF AN ELEVATED MIXED LAYER
(700-500 MB LAPSE RATES ~7.0 TO 8.5 C/KM) WILL YIELD SEASONABLY
STRONG DCAPE (1500-1800 J/KG), SUGGESTING AN INHERENTLY GREATER
POTENTIAL FOR SEVERE DOWNBURSTS ASSOCIATED WITH ANY CONVECTION.
LONG TERM /SUNDAY THROUGH SATURDAY/
ISSUED AT 1245 PM MDT SAT JUL 5 2025
SUN-MON: GUIDANCE INDICATES RELATIVELY LITTLE CHANGE IN THE
'BIG PICTURE', I.E. THE TRI-STATE AREA WILL REMAIN IN A WEAK
FORCING REGIME ON THE NORTHERN PERIPHERY OF AN UPPER LEVEL
RIDGE (ANCHORED OVER THE SOUTHERN PLAINS AND NORTHERN MEXICO) IN
WSW FLOW ALOFT. CONVECTIVE DEVELOPMENT, COVERAGE AND EVOLUTION
IN THE GOODLAND COUNTY WARNING AREA MAY BE INFLUENCED (DIRECTLY
OR INDIRECTLY) BY UPSTREAM AND/OR ANTECEDENT CONVECTION ON EACH
DAY. BOTTOM LINE, LOW CONFIDENCE IN FORECAST SPECIFICS
(CONVECTIVE MODE, COVERAGE, EVOLUTION). GUIDANCE DOES INDICATE
THAT AN UPPER LEVEL LOW DIGGING SOUTHWARD ALONG THE PACIFIC
COAST WILL TIGHTEN THE HEIGHT GRADIENT (AND MAGNITUDE OF WSW
FLOW ALOFT) OVER THE DESERT SOUTHWEST, 4-CORNERS AND PORTIONS
OF THE CENTRAL ROCKIES.. SUGGESTING THAT STRONGER DEEP LAYER
SHEAR (AND GREATER OVERALL SEVERE WEATHER POTENTIAL) WILL EXIST
ON BOTH SUN-MON.
TUE-SAT: LONG RANGE GUIDANCE INDICATES THAT RIDGING ALOFT WILL
PREVAIL OVER THE SOUTHERN CONUS, AND THAT THE TRI-STATE AREA
WILL REMAIN SITUATED ON THE NORTHERN PERIPHERY OF THE RIDGE, AT
OR NEAR THE SOUTHERN FRINGE OF THE MID-LATITUDE WESTERLIES.
BROADLY SPEAKING, EXPECT NEAR TO ABOVE AVERAGE TEMPERATURES AND
A DAILY POTENTIAL FOR LATE AFT-EVE CONVECTION (MAINLY IN
CLIMATOLOGICALLY FAVORED LOCATIONS DOWNSTREAM OF THE COLORADO
FRONT RANGE).. DEPENDING ON THE ORIENTATION OF THE RIDGE AND
PROXIMITY OF THE MID-LATITUDE WESTERLIES.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 943 PM MDT SAT JUL 5 2025
RAINFALL IS FORECAST TO BE OUT OF THE VICINITY OF THE KGLD
TERMINAL BY THE START OF THE TAF PERIOD. ADDITIONAL
REDEVELOPMENT IS POSSIBLE ACROSS EASTERN COLORADO THROUGH THE
NIGHT BUT AT THIS TIME DO THINK IT SHOULD REMAIN AWAY FROM THE
KGLD TERMINAL. WINDS ARE FORECAST TO BECOME SOUTHEASTERLY AGAIN
AROUND 12Z WITH MOISTURE ADVECTION. OVERALL GOOD CONSENSUS WITH
ANOTHER ROUND OF STORMS DEVELOPING DURING THE AFTERNOON AROUND
KMCK AND POTENTIALLY MERGING WITH ANOTHER ROUND OF CELLS MOVING
IN FROM THE THE WEST EVENTUALLY BECOMING A SOUTHWARD MOVING MCS.
DAMAGING WINDS AND PERHAPS SOME HAIL ALONG WITH VERY RAINFALL
IS FORECAST TO BE ASSOCIATED WITH ANY CELL. WILL INTRODUCE THE
PROB30 FOR NOW BUT IF THE SIGNAL CONTINUES THEN A TEMPO MAY BE
WARRANTED.
