ISSUED AT 1024 AM MDT FRI JUL 25 2014 MADE MINOR ADJUSTMENTS TO POP FORECAST GRIDS FOR INCREASING CLOUD TOPS OVER EAST CENTRAL UTAH. EXPECTING MORE ACTIVITY IN NORTHERN COLORADO TODAY THAN YESTERDAY...BUT STILL EXPECTING THE SAN JUANS TO BE BUSY THIS AFTERNOON DUE TO DAYTIME HEATING AND INSTABILITY. && .SHORT TERM...(TODAY THROUGH SATURDAY) ISSUED AT 415 AM MDT FRI JUL 25 2014 MONSOONAL MOISTURE CONTINUES TO STREAM OVER THE FORECAST AREA TODAY. PRECIPITABLE WATER REMAINS HIGH WITH VALUES EXCEEDING AN INCH IN THE DESERT VALLEYS. ISOLATED NOCTURNAL STORMS PERSIST IN THIS ENVIRONMENTAL...NO EXCEPTION THIS MORNING WITH AS A CLUSTER OF CELLS MOVED ACROSS MOFFAT AND ROUTT COUNTY. A SMALLER CLUSTER OF CELLS DEVELOPED OVER GRAND COUNTY IN UTAH AND CURRENTLY MOVING INTO MESA COUNTY. RADAR IS PICKING UP SOME RETURNS ACROSS THE FAR SOUTH...BUT NO LIGHTNING HAS BEEN OBSERVED. MORE SHOWERS AND THUNDER IS EXPECTED TODAY WITH CELLS MOVING FROM WSW TO ENE. CELL MOVEMENT IS FAST ENOUGH THAT THE CHANCE FOR ANY PROLONGED HEAVY RAIN IS QUITE SMALL. HOWEVER THE STRONGEST CELLS MAY MANAGE HEAVY RAINS TO CAUSE LOCALIZED MUD DEBRIS FLOWS AND ROCK SLIDES IN THE STEEPEST TERRAIN. ALONG THE WYOMING BORDER...THE THREAT OF CONVECTIVE STORMS DIMINISHES AS A TRAILING SHORT WAVE ADVECTS DRIER MORE STABLE AIR FROM THE WEST. MOST CONVECTION WILL CONTINUE INTO THE EVENING HOURS BUT BY AROUND 9PM...STORMS AND SHOWERS WILL SLOWLY START DYING OFF. EVEN SO...A FEW STRAY SHOWERS AND WEAK STORMS WILL PERSIST MUCH LIKE THURSDAY NIGHT. AS HAS BEEN THE CASE LATELY...AREAS SOUTH OF I-70 REMAIN FAVORED ESPECIALLY THE SAN JUANS. THE LOCATION OF THE HIGH PRESSURE ON SATURDAY APPEARS TO PUSH MONSOONAL MOISTURE MORE INTO UTAH WHICH ALSO SHOWS UP WITH FORECAST PWATS BEING A BIT LOWER THAN FRIDAY. HOWEVER...PLENTY OF MOISTURE WILL REMAIN IN THE ATMOSPHERE FOR ANOTHER ROUND OF CONVECTION TO FIRE WITH THE ROAN/TAVAPUTS...BOOKCLIFFS AND AREAS SOUTH FAVORED YET AGAIN. .LONG TERM...(SATURDAY NIGHT THROUGH THURSDAY) ISSUED AT 415 AM MDT FRI JUL 25 2014 THE AREA OF HIGH PRESSURE WILL CONTINUE TO WOBBLE OVER SRN CO AND NRN NM WITH MODELS HINTING AT A MORE DEFINITE PUSH OF MONSOONAL MOISTURE TO OUR WEST. PWATS LOOK TO DROP TO ABOUT .8 INCHES WHICH IS STILL ABOUT 120 PERCENT OF NORMAL. THAT BEING SAID...MORE CONVECTION ON THE WAY THOUGH COVERAGE WILL BE LESS THAN SEEN THE LAST FEW DAYS...FAVORING THE HIGHER TERRAIN. MONDAY THROUGH THURSDAY...NO SIGNIFICANT PATTERN CHANGE AS THE DESERT SOUTHWEST MONSOON STAYS ACTIVE. MEDIUM RANGE MODEL DO SHOW EASTERLY WAVES THAT ROTATE AROUND THE HIGH PRESSURE CENTER...BUT DIFFICULT TO FINE TUNE THESE DETAILS SEVERAL DAYS IN ADVANCE. THE BROADBRUSH APPROACH IS THE BEST FORECAST...THIS CURRENT PATTERN FAVORS AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS WITH LOCALIZED HEAVY RAINS AND ISOLATED NOCTURNAL STORMS. AFTERNOON TEMPS WILL BE NEAR AVERAGE...BUT NIGHTS WILL BE MILD/WARM AS NOCTURNAL BREEZES PREVENT ANY PRONOUNCED COOLING. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON) ISSUED AT 1024 AM MDT FRI JUL 25 2014 ALL TAF SITES CAN EXPECT SHOWERS AND/OR THUNDERSTORMS IN THE VICINITY THROUGH 04Z TONIGHT. THE MAIN THREAT FROM THUNDERSTORMS ARE EXPECTED TO BE BRIEF HEAVY RAIN AND ERRATIC WIND GUSTS 30-40 KTS...WITH MVFR CIGS AND MOUNTAIN OBSCURATIONS POSSIBLE FROM PASSING +SHRA/+TSRA. DECREASING -SHRA/-TSRA ARE EXPECTED AFTER 04Z TONIGHT. AFTER A MORNING LULL...ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WILL DEVELOP AFTER 18Z SAT AFTERNOON. && .FIRE WEATHER... ISSUED AT 415 AM MDT FRI JUL 25 2014 WINDS AND RH VALUES MAY BECOME NEAR CRITICAL FOR A FEW HOURS THIS AFTERNOON IN THE LITTLE SNAKE FORECAST AREA OF NORTHWESTERN COLORADO. AN UPPER LOW WILL TRACK OVER THE NORTHERN ROCKIES WILL TIGHTEN THE UPPER GRADIENT AND BRING DRIER AIR OVER NORTHWESTERN COLORADO. THE LOW WILL MOVE INTO THE NORTHERN PLAINS AND WINDS WILL RELAX AGAIN ON SATURDAY. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...NONE.
