AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
235 AM MDT THU JUN 23 2005
.SHORT TERM (TODAY THROUGH FRIDAY NIGHT)...
A BROAD AREA OF HIGH PRESSURE CONTINUED TO SPIN OVER THE SOUTHERN
PLAINS EARLY THIS MORNING. AS A RESULT...SUB-TROPICAL MOISTURE PLUME
ORIGINATING OVER MEXICO PERSISTED OVER THE AREA. ON A LOCAL SCALE...
A SHORTWAVE TROF OVER NORTHERN UTAH WAS MOVING SLOWLY NORTHEASTWARD
AND SHOULD EXIT INTO SOUTHERN WY EARLY THIS MORNING. MEANWHILE...A
TRAILING WAVE WAS MOVING NORTHEAST ACROSS SOUTHEAST UTAH AND WAS
GENERATING AN AREA OF SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
ACROSS EAST-CENTRAL UTAH AND WEST-CENTRAL CO.
NAM SEEMED TO HAVE THE BEST HANDLE ON THE SHORTWAVES MENTIONED ABOVE
SO BASED FORECAST ON THIS MODEL. SECOND SHORTWAVE WILL CONTINUE TO
BRING SHOWERS AND A FEW THUNDERSTORMS TO THE CENTRAL AND NORTHERN
MOUNTAINS AND SURROUNDING AREAS THIS MORNING. THEREFORE...INCREASED
POPS INTO THE SCATTERED CATEGORY IN THOSE AREAS. AS MENTIONED IN
PREVIOUS DISCUSSION...MOISTURE DEEPER WITH RELATIVELY HIGH DEW POINTS
ACROSS THE CWFA. THIS COMBINED WITH DIURNAL WARMING SHOULD BRING
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. SHEAR AND CAPE LIMITED SO
NOT EXPECTING STORMS TO BE PARTICULARLY STRONG. DRY THUNDERSTORMS NO
LONGER A THREAT AS AIRMASS HAS MOISTENED CONSIDERABLY OVER THE PAST
COUPLE OF DAYS. TEMPERATURES WILL CONTINUE SLOW COOLING TREND TODAY
LARGELY DUE TO CLOUDS AND SHOWERS. NOCTURNAL SHOWERS STILL A
POSSIBILITY TONIGHT...THOUGH CANNOT POINT TO ANY SPECIFIC DYNAMIC
FEATURE TO KEEP MOIST CONVECTION GOING. OVERNIGHT LOWS WILL CONTINUE
TO BE MILD AS A RESULT OF CLOUDS AND MOISTURE.
MORE OF THE SAME ON FRIDAY...THOUGH NAM HINTS AT SOME DRYING
ESPECIALLY IN THE FOUR CORNERS AREA. NOT ENTIRELY CONFIDENT OF THIS
SOLUTION SO CONTINUED WITH SCATTERED MOUNTAIN TSTMS WITH ISOLATED
POPS OVER THE LOWER VALLEY AREAS. LITTLE CHANGE IN TEMPERATURES
EXPECTED AS PATTERN SHOWS NO APPRECIABLE CHANGE.
.LONG TERM (SATURDAY THROUGH THURSDAY)...MODELS IN GOOD AGREEMENT.
THE RIDGE CURRENTLY CENTERED OVER NEW MEXICO WILL BEGIN TO SHIFT
EAST EARLY NEXT WEEK AS THE EASTERN PACIFIC TROF COMES ONSHORE. THIS
WILL BRING DRIER AND LESS HOT CONDITIONS TO THE REGION.
SATURDAY AND SUNDAY...CONTINUED DIURNAL THUNDERSTORMS EXPECTED WITH
PLENTY OF SUBTROPICAL MOISTURE TRAPPED IN THE RIDGE. TEMPS KEPT
BELOW RECORD WARMTH BY AFTERNOON CLOUDS/SHOWERS. THE STRONG
SHORTWAVE PROGGED IN THE GFS FOR SUNDAY IS REJECTED FOR NOW BUT
BEARS WATCHING.
MONDAY AND TUESDAY...THE NAM IS SLOWER BRINGING THE PACIFIC TROF
ONSHORE IN SPITE OF A MORE OPEN SOLUTION. STILL LEAN TOWARDS A SLOWER
SOLUTION AND HAVE KEPT LINGERING LATE DAY POPS MAINLY ALONG THE
CONTINENTAL DIVIDE. GFS SOLUTION WOULD LIMIT POPS TO THE NORTHERN
ZONES ON TUESDAY AS THE PAC TROF WORKS THRU CANADA.
WEDNESDAY AND THURSDAY...A DRIER BENIGN SW-W FLOW IN STORE...MORE
TYPICAL OF JUNE. RAMEY
&&
.HYDROLOGY...VERY WARM TEMPERATURES WILL CONTINUE TO MELT OUT MUCH OF
THE REMAINING HIGH ELEVATION SNOWPACK. THE UINTA MOUNTAINS OF
NORTHEAST UTAH HAVE THE HIGHEST REMAINING AMOUNTS LEFT TO MELT...AND
WILL KEEP THE DUCHESNE RIVER IN UINTAH COUNTY IN FLOOD CONDITION OVER
THE NEXT FEW DAYS.
