TODAY AND TONIGHT...
TODAY WILL START OFF WARM AND DRY AS A BROAD UPPER HIGH SITS OFF TO
OUR SOUTHWEST. HIGH TEMPERATURES WILL BE REALIZED EARLY IN THE DAY,
WARM BUT LESS SO THAN YESTERDAY, WITH 80S OVER THE VALLEYS AND MID-
80S TO HIGH-90S OVER THE EASTERN PLAINS. SHORTLY AFTER MIDDAY, A
SHORTWAVE DISTURBANCE WILL PASS THROUGH THE FLOW AS AN UPPER TROUGH
PASSES TO OUR NORTHEAST. A COLD FRONT WILL SURGE SOUTH ACROSS THE
PLAINS, LIKELY HITTING THE PALMER BY 1-2 PM AND MOVING SOUTH FROM
THERE THROUGH THE REST OF THE AFTERNOON. SHOWERS AND THUNDERSTORMS
WILL FIRE ALONG THE MOUNTAINS/PLAINS INTERFACE, WITH BREEZY STEERING
FLOW MOVING THINGS EAST THROUGH THE AFTERNOON AND INTO THE EVENING.
MOST OF THE SHORT-TERM GUIDANCE IS SHOWING THE STORMS ORGANIZING
SOMEWHAT, WITH A LINE OF CONVECTION CROSSING INTO KANSAS SOMETIME
BETWEEN 9 AND 11 PM OR SO. THERE IS A BIT OF VARIATION BETWEEN THE
MODELS AS FAR AS STORM ORGANIZATION IS CONCERNED, MAINLY LATER IN
THE EVENING, BUT THAT WILL CHANGE BASED ON HOW MUCH OUTFLOW
INTERACTIONS WE GET. SEVERE PARAMETERS LOOK DECENT AS WELL, WITH 500-
900 J/KG OF CAPE (DEPENDING ON THE MODEL), INCREASING OVER 1000 J/KG
CLOSER TO THE KS BORDER. EVEN SO, MID-LEVEL FLOW LOOKS A BIT WEAK,
MEANING SHEAR MAY NOT EXCEED 20 KNOTS IN MOST PLACES. THERE IS A
SLIGHT OUTLOOK FOR SEVERE STORMS OVER PORTIONS OF THE FAR EASTERN
PLAINS, AND A MARGINAL BACK TO THE SOUTHEAST MOUNTAINS, BUT THE
STRONGER STORMS MIGHT BE A BIT MORE DEPENDENT ON EITHER OUTFLOW
INTERACTIONS OR ENHANCED LOCAL FORCING FROM THE PASSING FRONT.
OVERNIGHT, PRECIPITATION WILL MOVE OFF TO THE EAST, WITH LOWS IN THE
50S TO LOW-60S OVER THE PLAINS, AND 40S IN THE HIGH VALLEYS.
MONDAY...
WITH THE FRONT THROUGH, MONDAY WILL BE A FAIR BIT COOLER THAN THE
LAST WEEK OR SO, WITH HIGHS ONLY HITTING THE 70S TO MID-80S OVER THE
EASTERN PLAINS. PRECIPITATION COVERAGE WILL QUICKLY INCREASE IN THE
AFTERNOON, SCATTERED OVER THE PLAINS WHILE THE MOUNTAINS, VALLEYS,
AND I-25 CORRIDOR WILL SEE MORE WIDESPREAD SHOWERS AND THUNDERSTORMS
THROUGH THE AFTERNOON AND EVENING HOURS. GIVEN THE INCREASED
MOISTURE, AND MORE ORGANIZED MID-LEVEL FLOW, A FEW STRONGER STORMS
WILL BE POSSIBLE AS WELL. WILL ALSO HAVE TO KEEP AN EYE ON THE BURN
SCARS FOR ANY FLASH FLOODING RELATED ISSUES, WHICH WILL LARGELY
DEPEND ON HOW LONG THE HEAVIER RAINFALL LINGERS IN THOSE AREAS.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
ISSUED AT 301 AM MDT SUN JUN 29 2025
TUESDAY THROUGH JULY 4TH WEEKEND...
WEATHER PATTERN THROUGH THIS FCST PERIOD NOT VARY ALL THAT MUCH.
SOME DAYS WILL BE A BIT DRIER THAN OTHERS (WEDNESDAY) BUT OVERALL
EXPECT SCATTERED STORMS IN THE MTNS, WITH MORE ISOLATED ACTIVITY
OVER THE PLAINS. TEMPERATURES WILL BE GENERALLY SEASONABLE THROUGH
THE PERIOD WITH MAINLY U80S TO M90S PLAINS, AROUND 80 LARGER VALLEYS
AND 60S AND 70S MTNS.
PRECIP IN THE MTNS WILL BE DRIVEN BY A MONSOON PATTERN DEVELOPING
OVER THE WEST, I.E., BROAD TROUGH OFF THE WEST COAST AND DOMINANT
RIDGE OVER THE CENTRAL PART OF THE COUNTRY. THIS PATTERN WILL BRING
A BROAD SOUTHERLY WIND FLOW OVER THE SW CONUS, AND WILL BRING UP
MOISTURE FROM OLD MEXICO. GIVEN THIS SETUP, THERE WILL BE A CHANCE
OF SOME LOCALLY HEAVY RAIN AT TIMES IN THE MTNS DURING THIS PERIOD,
AND SOME OF THIS PRECIP WILL LIKELY LINGER INTO THE NIGHTTIME
PERIOD.
WITH A MAJOR HOLIDAY COMING UP, 4TH OF JULY, IT APPEARS AT THIS TIME
SCATTERED AFTERNOON AND EVENING STORMS WILL BE PASSABLE OVER THE
ENTIRE REGION THIS DAY. STORMS DO NOT APPEAR TO BE ALL THAT STRONG.
TEMPS ON THE PLAINS RANGING FROM THE 80S ON THE RIDGES AND MID 90S
OVER THE LOWER ARK RVR VALLEYS, AND TEMPS AROUND 80 IN THE LARGER
VALLEYS WITH 60S AND 70S MTNS. WEATHER FOR THE JULY 4TH WEEKEND
APPEARS SIMILAR TO JULY 4TH ITSELF. \/HODANISH
