LOADED LATEST OBSERVATIONS INTO FRONT END OF FORECAST GRIDS.

UPDATE ISSUED AT 553 PM MDT THU JUN 25 2015

ADDED LARGE HAIL AND DAMAGING WIND THREAT TO NORTHEAST EL PASO
COUNTY FOR NEXT FEW HOURS. ALSO...LOADED LATEST OBSERVATIONS INTO

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 303 PM MDT THU JUN 25 2015

...MAIN CONCERN IS HOW SHORTWAVE DROPPING SE ACROSS THE PLAINS THIS
EVENING WILL AFFECT OUR WX...

CURRENTLY...

SHOWERS AND THUNDERSTORMS WERE PREDOMINANTLY ALONG THE MTNS...WITH
THE ACTIVITY MOVING SOUTHEAST. ONE OR TWO STORMS WERE ALSO NOTED
ALONG THE RATON MESA. A SHORTWAVE IN THE NW FLOW ALOFT WAS
APPROACHING NE COLO. CAPES WERE IN THE 1000-2000 RANGE ON THE
PLAINS...WITH THE HIGHER VALUES N OF US50. MARGINAL DEEP SHEAR WAS
NOTED OVER THE REGION.

REST OF THIS AFTERNOON INTO THIS EVENING...

WITH FLOW ALOFT TURNING WNW...STORMS WILL MOVE GENERALLY SOUTHEAST
WITH ANY OF THE STRONGER ROTATING CELLS MOVING GENERALLY DUE SOUTH.
MOST OF THE CONVECTION THROUGH 00Z WILL GENERALLY BE ALONG THE MTNS
AND DOWN ALONG THE RATON MESA. MAIN CONCERNS WILL BE
LIGHTNING...MARGINAL SEVERE AND LOCALLY HEAVY RAIN.

AFTER ABOUT 02Z...AREA WILL START TO BE INFLUENCED BY SHORTWAVE
MOVING SOUTHEAST AREA THE GREATER FAR NE COLORADO REGION. THIS WILL
BE OUR BEST CHANCE OF A STRONG TO SEVERE STORM TO AFFECT THE REGION.
LATEST GUIDANCE IS INDICATING BEST CHANCE WILL BE OVER THE FAR SE
COLO PLAINS. HOWEVER...HRRR DOES INDICATE ONE OR TWO ISOLD CELLS
MOVING S-SE CLOSER TO THE MTNS LATER THIS EVENING.

LATE TONIGHT...DEPENDING ON HOW STRONG THE CONVECTION IS WITH THE KS
MCS...WE WILL LIKELY SEE THE THREAT OF LOW CLOUDS AFFECTING THE
REGION...ESPECIALLY AFTER 09Z.

TOMORROW...

LIKELY WILL BE MOSTLY CLOUDY ACROSS THE PLAINS EARLY TOMORROW
MORNING...WITH PC SKIES OVER THE HIGHER TERRAIN. IT APPEARS THE
BEST FORCING FOR CONVECTION TOMORROW WILL BE THE S MTN REGION
(PIKES PEAK...WETS...SANGRES) AS THIS AREA WILL HAVE THE BEST
INSTABILITY. SPC HAS BACKED OFF ON THE STRENGTH OF THE STORMS
TOMORROW...WITH ONLY GENERAL THUNDER OVER THE FORECAST AREA.
DEPENDING HOW MUCH RICH LOW LEVEL MOISTURE REMAINS OVER THE
REGION TOMORROW...LOCALLY HEAVY RAIN WILL BE POSSIBLE...ESPECIALLY
IN THE S MTN REGION...AND POSSIBLY THE EAST SLOPES OF THE SAN
JUANS. IF CAP CAN BREAK...THEN WE MAY BE DEALING WITH A FEW
STRONGER STORMS GIVEN THE CAPE AND MARGINAL SHEAR OVER THE REGION.

TEMPS TOMORROW WILL BE ABOUT 4-8F COOLER ACROSS THE PLAINS...WITH
HIGHS MAINLY IN THE L80S.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 303 PM MDT THU JUN 25 2015

VERY LITTLE CHANGE NEEDED TO THE OVERALL TREND WHEN IT COMES TO THE
ONGOING LONG TERM FORECAST.

A RIDGE OF HIGH PRESSURE WILL REMAIN CENTERED OVER THE GREAT BASIN
THROUGH THE EXTENDED PERIOD...WITH THE FORECAST AREA LOCATED TO THE
EAST OF THE RIDGE UNDER LIGHT NORTH TO NORTHWEST FLOW ALOFT.
TEMPERATURES ARE EXPECTED TO REMAIN NEAR SEASONAL NORMS WITH MAX
TEMPS EACH DAY IN THE MID 80S TO MID 90S FOR THE PLAINS...AND 80S
FOR THE HIGH VALLEYS. THE WARMEST DAYS IN THE EXTENDED LOOK TO BE
TUE AND WED.

CONVECTION MAY LINGER A BIT LATER INTO THE OVERNIGHT PERIOD FRI
NIGHT...OTHERWISE SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED TO BE
MAINLY DIURNAL IN NATURE...DEVELOPING OVER THE HIGHER TERRAIN BY
MIDDAY EACH DAY AND THEN PROGRESSING ACROSS THE ADJACENT AREAS
THROUGH THE AFTERNOON AND EVE. CONVECTION WILL BE SCATTERED IN
NATURE OVER THE MTS...AND ISOLATED OVER THE LOWER ELEVATIONS. THE
DRIEST DAYS OF THE EXTENDED LOOK TO BE MON AND TUE...AND THE
PLAINS ON THOSE DAYS MAY REMAIN PCPN-FREE. THE GFS IS INDICATING
THAT A COLD FRONT FORECAST FOR WED WILL BE A BIT SLOWER...ARRIVING
ACROSS THE EASTERN PLAINS WED AFTERNOON/EVE. THIS WILL INCREASE
CONVECTION CHANCES ONCE AGAIN LATE WED NIGHT THROUGH THU. MOORE

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)
ISSUED AT 303 PM MDT THU JUN 25 2015

MAIN CONCERN AT THE TAF SITES WILL BE AFTERNOON CONVECTION BOTH
TODAY AND TOMORROW AFTERNOON....AND LOW CIGS AT KCOS AND KPUB
TONIGHT. ISOLD TSRA WILL LIKELY OCCUR AT ALL TAF SITES THIS
AFTERNOON AND TOMORROW AFTERNOON...WITH BRIEF MVFR CONDITIONS DUE
TOT THE STORMS. MAY ALSO SEE SOME LOCALLY STRONG GUSTY WINDS.

AT KPUB AND KCOS...LOWER CIGS WILL LIKELY DEVELOP LATER TONIGHT AND
LAST INTO TOMORROW MORNING AS A MOIST AIRMASS IN W KS PUSHES BACK TO
THE MTNS. LOWE CIGS...IF THEY DEVELOP...SHOULD DISSIPATE BY MID
MORNING TOMORROW.
