GENERALLY IN THE 65-70F RANGE.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 340 AM MDT SUN JUL 5 2015

MODELS AND ENSEMBLES IN GOOD AGREEMENT THROUGH THE EXTENDED PERIOD
WITH GENERALLY ACTIVE WEATHER ACROSS THE REGION.

MONDAY...A COLD FRONT IS FORECAST TO HAVE PASSED SOUTH ACROSS THE
EASTERN PLAINS BY MONDAY MORNING WITH LOW LEVEL EASTERLY UPSLOPE
FLOW ACROSS THE REGION. ABUNDANT MOISTURE AND WEAK ENERGY MOVING
ACROSS THE ROCKIES WILL COMBINE WITH THE LOW LEVEL UPSLOPE FLOW TO
PRODUCE WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY ACROSS THE
REGION. PRECIPITATION WILL LIKELY BE MODERATE TO
HEAVY...ESPECIALLY OVER AND ALONG THE LEE SLOPES OF THE EASTERN
MOUNTAINS. AREA STREAMS AND RIVERS WILL NEED TO BE MONITORED FOR
FLOOD CONDITIONS WITH ADDITIONAL RAINFALL ACROSS THE AREA.
TEMPERATURES WILL BE COOLER WITH 70S TO LOWER 80S FOR HIGHS OVER
THE PLAINS.

TUESDAY...THE UPPER LEVEL PATTERN BEGINS TO CHANGE ON TUESDAY WITH
INCREASING SOUTHWESTERLY FLOW ALOFT. THIS WILL CONTINUE TO PUMP
MOISTURE OUT OF THE DESERT SOUTHWEST INTO SOUTHERN COLORADO. LOW
LEVEL FLOW WILL CONTINUE TO BE SOUTHEASTERLY UPSLOPE. SHOWERS AND
THUNDERSTORMS ARE FORECAST TO DEVELOP OVER THE MOUNTAINS BY
TUESDAY AFTERNOON...AND SPREAD EAST ACROSS THE PLAINS THROUGH THE
EVENING HOURS. MODERATE TO HEAVY RAINFALL WILL ONCE AGAIN BE
POSSIBLE...ESPECIALLY OVER THE MOUNTAINS...AND THE FLOOD RISK WILL
CONTINUE TO BE ELEVATED.

WEDNESDAY...MODELS DIFFER ON THE THREAT FOR THREAT FOR STRONG TO
SEVERE STORMS WEDNESDAY AFTERNOON AND EVENING OVER THE PLAINS.
MOISTURE WILL CONTINUE TO MOVE IN FROM THE SOUTHWEST. MOUNTAIN
SHOWERS AND THUNDERSTORMS ARE A GIVEN DURING THE AFTERNOON AND
EVENING HOURS. THE DIFFERENCE COME IN TO PLAY WITH A POSSIBLE
DRYLINE SETTING UP OVER THE FAR EASTERN PLAINS. THE GFS DEVELOPS
THUNDERSTORMS NEAR THE KANSAS BORDER WEDNESDAY AFTERNOON AND
EVENING. SHEAR IS MARGINAL AND INSTABILITY MODEST...SO IF STORMS
DO FOCUS ALONG THE DRYLINE...THEY MAY BECOME STRONG TO SEVERE WITH
LARGE HAIL AND HEAVY RAINFALL THE PRIMARY THREATS. THE ECMWF IS
NOT AS STRONG WITH CONVECTION OVER THE EASTERN PLAINS ALONG A
FOCUSED BOUNDARY. IT PREFERS AN MCS DEVELOPMENT AFTER CONVECTION
ROLLS OFF THE MOUNTAINS AND MOVES EAST ACROSS THE PLAINS. ONE
THING IS FOR CERTAIN...WHERE RAIN FALLS...IT WILL LIKELY BE HEAVY
WITH A CONTINUED FLOOD THREAT ACROSS THE REGION.

THURSDAY THROUGH SATURDAY...A MONSOON LIKE PATTERN IS FORECAST TO
PERSIST THURSDAY INTO FRIDAY WITH DEEP SOUTHWEST FLOW AND ABUNDANT
MOISTURE FLOWING INTO THE AREA. DAILY MOUNTAIN CONVECTION WILL
CONTINUE EACH AFTERNOON AND EVENING...WITH ACTIVITY LIKELY
SPREADING EASTWARD INTO THE PLAINS. LOCALLY HEAVY RAINFALL WILL
REMAIN POSSIBLE. DRIER CONDITIONS ARE EXPECTED ON SATURDAY AS FLOW
TURNS MORE WESTERLY WITH LIMITED ACTIVITY ACROSS THE MOUNTAINS.
TEMPERATURES WILL ALSO WARM ACROSS THE REGION THURSDAY THROUGH
SATURDAY WITH 80S AND 90S FOR HIGHS.  MOZLEY
