332 PM MDT SAT MAY 10 2014
.SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 332 PM MDT SAT MAY 10 2014
THE STORM WHICH WILL IMPACT THE REGION DURING THE REMAINDER OF THE
WEEKEND TAKING SHAPE OVER THE PACIFIC NORTHWEST EARLY TODAY. AHEAD
OF THIS SYSTEM A WEAK DISTURBANCE WAS MOVING OVER THE AREA
GENERATING SOME LIGHT OVERRUNNING SHOWERS...MAINLY NORTH OF THE
I-70 CORRIDOR. SHOWERS WILL BECOME MORE CONVECTIVE IN NATURE THIS
AFTERNOON AS LAPSE RATES STEEPEN IN RESPONSE TO DAYTIME HEATING. A
FEW THUNDERSTORMS ARE POSSIBLE. SNOW LEVEL FROM 9500 TO 10000 FEET
SO EXPECT SOME LIGHT ACCUMULATIONS IN THE HIGH PASSES. IN LIGHT OF
THIS...CONSIDERED STARTING WINTER STORM WARNINGS EARLY FOR THE
NORTHERN MOUNTAINS BUT BELIEVE IMPACTS WILL BE MINOR BEFORE
SUNDOWN SO HELD OFF.
MODELS REMAIN CONSISTENT IN DROPPING THE STORM/S CENTER SOUTH-
SOUTHEASTWARD FROM NEAR BOISE THIS EVENING TO SOUTHWEST UTAH BY
12Z SUNDAY. AS THIS OCCURS...FRONTOGENETIC FORCING WILL INTENSIFY
BAROCLINICITY ALONG THE WARM FRONT DRAPED OVER THE NORTH. LOW-
LEVEL CONVERGENCE ALONG THE BOUNDARY COMBINED WITH INCREASING
MID-LEVEL DIVQ AND STRONG JET LEVEL DIVERGENCE WILL RESULT IN
WIDESPREAD PRECIPITATION FOR AREAS ALONG...BUT MAINLY NORTH OF THE
I-70 CORRIDOR. SNOW LEVELS REACH THE MOUNTAIN BASES OF THE ELKHEAD
AND EASTERN UINTA MOUNTAINS BY SUNRISE SO LOWER ELEVATIONS OF THE
NORTH AND ALONG THE I-70 CORRIDOR WILL REMAIN IN RAIN THROUGH THE
NIGHT. SHOWER ACTIVITY MORE SCATTERED OVER THE LOWER ELEVATIONS OF
SOUTHEAST AND SOUTHWEST COLORADO WHERE DYNAMIC FORCING AND
MOISTURE MORE LIMITED THOUGH INSTABILITY MORE FAVORABLE FOR
ISOLATED THUNDERSTORMS.
THE STORM CENTER SHIFTS TO SOUTHWEST COLORADO DURING THE LATTER
PART OF THE DAY SUNDAY. UPWARD FORCING REMAINS IMPRESSIVE ACROSS
THE FORECAST AREA WHICH SHOULD TRANSLATE INTO PRECIPITATION IN ONE
FORM OR ANOTHER REGIONWIDE. CAA ACROSS THE NORTH AND ON THE
BACKSIDE OF THE LOW OVER SOUTHEAST UTAH WILL BRING SNOW TO THE
LOWER ELEVATIONS IN THESE AREAS. MEANWHILE...WARM SECTOR REMAINS
OVER SOUTHWEST COLORADO SO EXPECT RAIN ALONG WITH A FEW
THUNDERSTORMS. MOUNTAINS WILL CONTINUE TO RECEIVE MODERATE TO
HEAVY SNOW AND SOME BLOWING SNOW...ESPECIALLY ACROSS THE EASTERN
UINTA MOUNTAINS WHERE 7H WINDS RANGE FROM 40 TO 50 KTS FROM THE
NORTHEAST. EXPECT FLOW OVER THE EASTERN END OF THE UINTAS LIKELY
TO BRING ADVISORY LEVEL WIND TO A GOOD PORTION OF THE EASTERN
UINTA BASIN AND WILL HOIST NPW WITH THIS PACKAGE.
THOUGH DYNAMICS WANE SUNDAY NIGHT PLENTY OF MOISTURE AND INSTABILITY
TO KEEP SNOW GOING IN THE COLORADO MOUNTAINS AND ITS HIGH VALLEYS
THROUGH THE NIGHT. CURRENT WINTER HILITES APPEARED ON TRACK AND
MADE NO CHANGES TO THIS PACKAGE. LOWER VALLEYS STILL APPEARED TOO
WARM FOR ANY ACCUMULATING SNOW UNTIL LATE SUNDAY NIGHT WHEN
PRECIPITATION CHANCES ON THE DECLINE.
INFLUX OF COLDER AIR NOT SO PROFOUND YET TONIGHT...BUT BY SUNDAY
AFTERNOON TEMPERATURES WILL BE MUCH COLDER (ON THE ORDER OF 15 TO
20 DEGREES). FREEZING TEMPERATURES FOR LOWER ELEVATIONS POSSIBLE
LATE SUNDAY NIGHT AND WILL ISSUE FREEZE WATCH FOR THOSE AREAS
WHERE VEGETATION THREATENED.
.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 332 PM MDT SAT MAY 10 2014
TROUGH IS A LITTLE SLOW LEAVING ON MONDAY AS SECONDARY ENERGY ON ITS
BACKSIDE DROPS SOUTH ACROSS THE FORECAST AREA AND WILL KEEP SOME
SHOWERS IN MAINLY WESTERN CO. BOOSTED POPS A BIT ON MONDAY AS A
RESULT. 700 MB WIND FIELD SHOWED THIS ENERGY FORMING A WEAK LOW
CIRCULATION OVER SW CO MONDAY AFTERNOON AND NIGHT...SO ALSO KEPT A
CHANCE OF SHOWERS OVER THE SAN JUANS MONDAY NIGHT WHILE TAPERING
OFF POPS ACROSS THE NORTHERN AND CENTRAL MTNS AFTER MIDNIGHT.
MONDAY NIGHT LOOKS QUITE CHILLY WITH WIDESPREAD FREEZING TEMPS
POSSIBLE AS SKIES BEGIN TO CLEAR IN CONTINUED NORTHERLY FLOW AND
WEAK COLD ADVECTION.
NORTHERLY FLOW CONTINUES ON TUESDAY BUT SHOULD BE DRIER WITH PRECIP
WATER VALUES DROPPING TO OR BELOW 1/4 INCH. DOWNWARD QG FORCING
SHOULD ALSO WORK TO SUPPRESS PRECIPITATION WITH ONLY SOME ISOLATED
SHOWERS POSSIBLE OVER THE CENTRAL AND SOUTHERN CO MTNS.
TEMPERATURES RECOVER TO SEASONABLE OR ABOVE NORMAL LEVELS THE LAST
HALF OF NEXT WEEK AS A RIDGE OF HIGH PRESSURE DEVELOPS OVER THE FAR
WEST...THEN SHIFTS OVER THE GREAT BASIN BY NEXT WEEKEND. HIGHS
AROUND 90 ARE POSSIBLE IN FAR SE UT FRIDAY AND SATURDAY.
GENERALLY DRY NORTHWEST FLOW IS EXPECTED INTO FRI THOUGH SMALL
EMBEDDED DISTURBANCES WILL BRING SOME CLOUDS AND A SLIGHT CHANCE
OF SHOWERS TO THE NRN CO MTNS ABOUT THURSDAY.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 1108 AM MDT SAT MAY 10 2014
OVERRUNNING AND THICK CLOUD DECK OVER ALL BUT THE SOUTHERN EDGE
OF THE FORECAST AREA THIS MORNING AND WILL CONTINUE TO LOWER
THROUGH THIS AFTERNOON AS A MAJOR WINTER LIKE STORM APPROACHES.
LIGHT MOUNTAIN SNOW/VALLEY RAIN SHOWERS OVER THE CENTRAL-NORTHERN
PORTION WILL ALSO SPREAD AND INCREASE IN COVERAGE AND INTENSITY
THIS AFTERNOON...WITH A CHANCE OF THUNDER DEVELOPING. MVFR WILL BE
EXPECTED WITH SOME SHOWERS AND LOW CLOUDS THIS AFTERNOON...WITH
ISOLATED IFR POSSIBLE. CONDITIONS WILL DETERIORATE THIS EVENING AS
PRECIPITATION INCREASES AND THE SNOW LEVEL LOWERS. WIDESPREAD
MOUNTAIN OBSCURATIONS WILL ARE EXPECTED. THESE POOR FLYING
CONDITIONS WILL PERSIST THROUGH SUNDAY...WITH SNOW DROPPING INTO
ALL BUT THE LOWEST VALLEYS. ALSO ALONG EXPOSED PEAKS AND
RIDGES...SOME MECHANICAL TURBULENCE WILL RESULT FROM MODERATE TO
STRONG SOUTHWEST WINDS THROUGH THE EVENING.
