AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
430 AM MDT SAT APR 16 2016

.SHORT TERM...(TODAY THROUGH SUNDAY)
ISSUED AT 430 AM MDT SAT APR 16 2016

THE STORM SYSTEM DISCUSSED EXTENSIVELY OVER THE PAST SEVERAL DAYS
CONTINUED TO BRING RAIN AND SNOW TO THE AREA DURING THE NIGHT.
LATEST SATELLITE IMAGERY PLACED THE MID-LEVEL STORM CENTER OVER
GALLUP...NM EARLY THIS MORNING. SNOW LEVELS HAVE FALLEN IN THE
WAKE OF THE COLD FRONT ASSOCIATED WITH THIS SYSTEM WITH CORTEZ
INDICATING LIGHT SNOW AS OF 0307 MDT. AS MENTIONED IN THE PREVIOUS
DISCUSSION THE HEAVY...WET SNOW MAY BRING SOME LIGHT ACCUMULATIONS
TO GRASSY AREAS BUT WILL LARGELY MELT ON PAVEMENT. CONSEQUENTLY
...DO NOT ANTICIPATE EXPANDING WINTER WEATHER HIGHLIGHTS INTO THE
LOWER ELEVATIONS. MEANWHILE...MOUNTAIN SNOTELS INDICATED
ACCUMULATIONS BETWEEN 4 AND 8 INCHES SINCE THE STORM BEGAN.

THE LOW IS EXPECTED TO CONTINUE TO SHIFT THE NORTHEAST DURING THE
DAY. BANDS OF ENERGY EJECTED FROM THE STORM CENTER WILL CONTINUE
TO BRING RAIN AND SNOW TO THE AREA DURING THE DAY. DAYTIME WARMING
WILL CAUSE SNOW LEVELS TO RISE FROM VALLEY BOTTOMS. MEANWHILE...
AS THE LOW SHIFTS A TIGHT SURFACE AND MID-LEVEL GRADIENT FORMS
OVER NORTHWEST COLORADO AND EASTERN UTAH. 40 TO 50 KT WINDS AT THE
7H LEVEL ARE INDICATED OVER THIS AREA. GIVEN STRONG 7H FLOW LIKELY
ENHANCED BY SHOWER ACTIVITY AND THE STRONG SURFACE GRADIENT...HAVE
BECOME CONVINCED THAT ADVISORY CRITERIA WILL BE MET OVER MUCH OF
THE AREA DESCRIBED. CONSEQUENTLY...HAVE HOISTED A WIND ADVISORY AS
DELINEATED IN THE WATCH/WARNING/ADVISORY SECTION WHICH FOLLOWS
BEGINNING AT 0900 MDT AND CONTINUING THROUGH 1900 MDT THIS
EVENING.

THE STORM CENTER RETROGRADES TONIGHT THROUGH MONDAY SO EXPECT
PERIODS OF SHOWER ACTIVITY WILL CONTINUE. THERE IS THE POTENTIAL
THAT WINTER WEATHER HIGHLIGHTS FOR THE COLORADO DIVIDE MAY NEED TO
BE EXTENDED...BUT PREMATURE TO MAKE THE CALL AT THIS POINT.

TEMPERATURES WILL REMAIN COOLER THAN NORMAL TODAY THROUGH MONDAY
AS THE STORM LINGERS OVER THE AREA. DAYTIME HIGHS WILL CONTINUE TO
RUN 10 TO 15 DEGREES BELOW SEASONAL NORMS AND OVERNIGHT LOWS WILL
BE ABOUT 5 TO 10 DEGREES BELOW NORMAL.

.LONG TERM...(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 430 AM MDT SAT APR 16 2016

HARD TO BELIEVE...BUT THE DEEP UPPER LOW OVER THE REGION WILL
STILL BE WREAKING HAVOC ON THE FORECAST AREA THROUGH THE DAY ON
MONDAY AS FLOW BECOME MORE WESTERLY WITH THE MAIN CENTER OF
CIRCULATION NOW SETTING UP OVER SOUTH CENTRAL WYOMING (AS STATED
ABOVE...THIS IS A COMPLEX STORM). IN ANY CASE...MOISTURE OVER THE
REGION AND FAVORABLE WESTERLY COMPONENT WILL KEEP SNOW GOING OVER
THE NORTHERN AND CENTRAL MOUNTAINS. VALLEYS SHOWERS WILL STILL BE
IN PLAY AS WELL...ESPECIALLY ACROSS NORTHWEST COLORADO. THE LOW
FINALLY KICKS EAST MONDAY NIGHT. RESIDUAL MOISTURE IS LIKELY TO
CONTINUE TO BRING SNOW SHOWERS TO THE DIVIDE MOUNTAINS THROUGH
MIDWEEK BEFORE HIGH PRESSURE BUILDS OVER THE AREA WEDNESDAY NIGHT.
DRY CONDITIONS AND MILDER TEMPERATURES IN STORE DURING THE LATTER
HALF OF THE WEEK.
