MODELS SIMILAR THROUGH 48 HOURS AND THEN SOME DIFFERENCES. THE GFS
BRINGS AN UPPER LEVEL NORTH FROM THE GULF OF ALASKA SAT AS DOES
THE NAM AND THE ECMWF BUT THE GFS CONTINUES IT AND GIVES IT MORE
PLAY. HOWEVER...THE 06Z GFS RUN DOES WEAKEN IT SUBSTANTIALLY MORE
AND EVEN DISSIPATES IT IN PLACE IN THE CENTRAL INTERIOR. THE ONLY
REAL REASON IS THAT THIS IS OF ANY IMPORTANCE IS BECAUSE OF
CONVECTIVE CONSEQUENCES. THE GFS WOULD PROVIDE A LITTLE MORE
INSTABILITY TO THE CENTRAL AND EASTERN INTERIOR IN THE SHORT TERM.
THE ABOVE NORMAL TEMPERATURES HAVE BEGAN AS PREVIOUSLY THOUGHT.
THESE WILL CONTINUE FOR THE FORESEEABLE FUTURE. THIS WILL SPEED UP
BREAK UP. FLOODING FROM BREAK UP IS WORKING ITS WAY WEST AS IS
ALLUDED TO IN THE WATCH STATEMENTS.
A SHORT WAVE MOVING NORTH ALONG THE WEST COAST IS GOING TO BE HELD
AT BAY BY THE EXPANDING RIDGE THAT IS BUILDING WESTWARD. MOST OF
THAT MOISTURE WILL BE WEST OF MAINLAND ALASKA. IT WILL SKIRT THE
Y-K DELTA AND THEN IMPACT ST. LAWRENCE ISLAND. ANOTHER WAVE WILL
ROTATE WESTWARD FROM THE GULF OF ALASKA ON MON AND WILL PROVIDE
SOME MORE LIGHT SHOWERS TO ZONE 214 AND 215 MON AND MON NIGHT.
500H CONTINUE TO CLIMB WHILE 850H TEMPERATURES CLIMB AS WELL
BEGINNING THE FIRST PART OF THE WEEK. THIS SHOULD LIMIT CONVECTION
AS THE AIR MASS STABILIZES.

UPPER LEVEL RIDGE WITH EAST WEST AXIS CONTINUES TO BUILD INTO
EASTERN AND CENTRAL INTERIOR ALASKA THROUGH MONDAY AND CONTINUES
TO BUILD TO THE WEST THROUGH THE MIDDLE OF THE WEEK. ON THE
SURFACE A LOW SOUTH OF COLD BAY WILL CONTINUE TO MOVE NORTH AND
WEST INTO THE SOUTHERN BERING SEA WHILE A WEAK TROUGH OVER THE
GULF OF ANADYR MOVES NORTHEAST. A LOW 300 NM NORTHWEST OF BARROW
WILL CONTINUE TO MOVE EAST WHILE WEAK RIDGING BUILDS OVER THE
NORTH SLOPE. AREAS OF FOG WILL CONTINUE OVER NIGHT ALONG THE NORTH
SLOPE.
FORECAST FOCUS IS ON THE SUMMER LIKE TEMPERATURES AT THE SURFACE
ALONG WITH FREEZING LEVELS AT OR ABOVE 6500 FT ACROSS THE INTERIOR
THROUGH MIDDLE OF NEXT WEEK. WILL NEED TO MONITOR RUN OFF INTO
INTERIOR STREAMS AND SMALL RIVERS AS DEEP AND LATE SEASON SNOW
PACK STILL EXISTS ACROSS MUCH OF THE INTERIOR ABOVE 2500 FT.
SMALL RIVERS AND STREAMS IN THE EASTERN AND CENTRAL INTERIOR WILL
BE RUNNING AT OR NEAR BANK FULL. RVS ISSUED THIS MORNING...WILL
NEED TO MONITOR FOR ADDITIONAL STATEMENTS OR HEADLINES.
MODELS ARE IN GOOD AGREEMENT THROUGH THE MIDDLE OF NEXT WEEK WITH
UPPER LEVEL HIGH PRESSURE RIDGE PARKING OVER EASTERN AND CENTRAL
INTERIOR THIS WEEKEND AND EXPANDING TO THE WESTERN INTERIOR AND
WEST COAST THROUGH MIDDLE OF THE WEEK.
&&
.FIRE WEATHER...
WARM AND DRY AIR MASS OVER THE INTERIOR WILL DROP MIN RH VALUES
INTO THE MID TEENS FOR ZONES 220 223 AND 224 WHERE RED FLAG
WARNINGS ARE HOISTED FOR TOMORROW. WINDS HOWEVER ARE EXPECTED TO
REMAIN LIGHT.
&&
.HYDROLOGY...
THE ICE FRONT ON THE YUKON PASSED DOWN RIVER OF RAMPART AT 230 AM
THIS MORNING AND IS MOVING DOWN RIVER TOWARD TANANA. FLOOD WATCH
REMAINS IN EFFECT FOR THE YUKON RIVER FROM RAMPART DOWN RIVER TO
TANANA. AN ICE JAM FORMED THIS MORNING ON THE KUSKOKWIM JUST DOWN
RIVER FROM THE MCGRATH AIRPORT WHERE A FLOOD WATCH IS ALSO IN
EFFECT. A FLOOD ADVISORY FOR THE SNAKE AND NOME RIVERS ON NEAR
NOME WILL BE ALLOWED TO EXPIRE THIS AFTERNOON AS WATERS CONTINUE
TO RECEDE. RVS ISSUED THIS MORNING FOR ZONES 222...223...224 AND
226 WITH CONCERNS WITH SMALL STREAMS AND RIVERS WATER LEVELS
INCREASING TO NEAR BANK FULL AS SUMMER LIKE TEMPERATURES CAUSE
MELT OFF FROM DEEP AND LATE SEASON SNOW PACK ACROSS THE INTERIOR

MODELS IN DECENT AGREEMENT THROUGH ABOUT 60 HOURS WITH ONLY MINOR
POSITION DIFFERENCES. UPPER LEVEL RIDGE IS WEAK OVER THE INTERIOR
AS IT STRETCHES WESTWARD TO THE WEST COAST TODAY. THERMAL TROUGH
IS WEAK WITHIN THE RIDGE UNTIL LATE AFTERNOON WHEN THE TROUGH
BEGINS TO STRENGTHEN. THE 500H WAVERS BACK AND FORTH A FEW
DECAMETERS OVER THE COURSE OF THE NEXT 120 HOURS AND BEYOND.
NONE OF THE MODELS ARE EXCITED ABOUT ANY CONVECTIVE POTENTIAL
THROUGH AT LEAST SAT. BEGINNING SUN...500H REMAIN NEARLY CONSTANT
WHILE LOWER LEVEL TEMPERATURES DRASTICALLY INCREASE WHICH WITHIN
THE THERMAL TROUGH WOULD LIKELY BE ENOUGH OF A TRIGGER TO AT LEAST
SPAWN A FEW SHOWERS IN THE FAR EASTERN INTERIOR SUN AND MON.
TEMPERATURES WILL CONTINUE TO BE ON THE INCLINE OVER THE NEXT
SEVERAL DAYS. THE CLIMB IN TEMPERATURES WILL CREATE ABOVE NORMAL
TEMPERATURES FOR MUCH OF NORTHERN ALASKA THROUGH AT LEAST THE
FIRST PART OF THE WEEK. THIS WILL AID IN THE SNOW MELT AND COULD
EXACERBATE AN ALREADY DELICATE BREAK UP ON INTERIOR RIVERS. A
MODERATELY STRONG COLD FRONT IS ADVERTISED TO SWEEP DOWN OVER THE
NORTHWEST ARCTIC COAST BY TUE ACCORDING TO THE GFS WHILE THE ECMWF
SHOWS NO COLD FRONT ANYWHERE NEAR ALASKA. BUT BOTH MODELS DO SHOW
A DECENT THERMAL TROUGH OVER THE EASTERN INTERIOR.
&&
.FIRE WEATHER...A GENERAL INCREASE IN LOWER LEVEL MOISTURE OVER
MUCH OF NORTHERN ALASKA WILL CONTINUE TO KEEP RH VALUES ABOVE 30
PERCENT FOR MANY LOCATION EXCEPT FOR THE FAR EASTERN
INTERIOR...PARTICULARLY ALONG THE ALCAN BORDER.

A GRADUAL TRANSITION TO A SUMMER DOG-DAYS LIKE UPPER AIR PATTERN
IS EXPECTED OVER THE NEXT FEW DAYS AS A BROAD HIGH PRESSURE RIDGE
ALOFT GRADUALLY BUILDS OVER THE INTERIOR. ECMWF AND GEFS ENSEMBLE
MEANS INDICATING THE RIDGE PERSISTING THROUGH NEXT WEEK. NCEP/CPC
ENSEMBLE MEAN TEMPERATURE FORECAST INDICATES POSITIVE TEMPERATURE
ANOMALIES OF 2-3 DEGREES CELSIUS OVER MOST OF NORTHERN ALASKA FROM
THE BROOKS RANGE SOUTHWARD. A WEAK SHORT WAVE MAY POKE NORTHWARD
INTO THE EASTERN INTERIOR MONDAY...THIS COULD INCREASE THE CHANCE
OF SOME ISOLATED THUNDERSTORM ACTIVITY. OTHERWISE...ENOUGH LOW
LEVEL INSTABILITY FOR SOME SHALLOW CONVECTION...VIRGA AND/OR
ISOLATED SHOWERS...IN PARTS OF THE EASTERN INTERIOR.
&&
.FIRE WEATHER...
WARMER AND DRIER CONDITIONS EXPECTED OVER MUCH OF THE INTERIOR
FRI INTO NEXT WEEK. MIN RH COULD BE NEAR 15 PERCENT AT SOME
LOCATIONS THROUGH THE WEEKEND. SURFACE WINDS ARE EXPECTED
TO REMAIN LIGHT...SO ANY RED FLAG WARNINGS WOULD BE FOR LOW RH.

MODELS ARE MOSTLY SIMILAR THROUGH 48 HOURS. UPPER LEVEL LOW IN
WESTERN CANADA WILL CONTINUE TO TRACK NORTHWARD TO SOUTH OF BANKS
ISLAND BY FRI AFTERNOON. THIS WILL ALLOW THE UPPER LEVEL RIDGE TO
BUILD IN FROM WESTERN CANADA AND EXTEND WESTWARD ACROSS NORTHERN
ALASKA REACHING THE WEST COAST BY SAT EVENING.
THIS BUILDING OF THE RIDGE WILL PUSH MUCH WARMER AIR INTO ALASKA
AND WATCH THE HEIGHTS CONTINUE TO CLIMB. A VERY WEAK UPPER LEVEL
TROUGH WILL MOVE NORTH SAT BUT THE CONVECTIVE PARAMETERS ARE SO
PATHETIC OVER THE CENTRAL INTERIOR THAT AT THIS POINT IT IS
UNLIKELY THAT IT WILL PRODUCE ANYTHING MORE THAN A COUPLE OF STRAY
SHOWERS. HOWEVER...ON SUN AND MON MORE INSTABILITY CREEPS BACK
INTO THE EASTERN INTERIOR WITH THE BUILDING THERMAL TROUGH AND A
WEAK UPPER LEVEL TROUGH DRAPED ACROSS THE CENTRAL INTERIOR RUNNING
NORTHEAST THROUGH SOUTHWEST. THIS COULD PRODUCE A BETTER CHANCE OF
MORE WIDELY SCATTERED SHOWERS.
AN APPROACHING COLD FRONT ALONG THE NORTHWEST ARCTIC COAST WILL
WEAKEN CONSIDERABLE AS IT TRIES TO PUSH EAST BUT WILL GET HUNG UP
OVER THE EASTERN BROOKS RANGE WHICH WILL LIKELY PRODUCE SOME
SHOWERS AT LOWER ELEVATIONS AND SNOWFALL IN THE MOUNTAINS.
THE THERMAL TROUGH WILL EXTEND FROM THE EAST THROUGH THE WEST
BEGINNING SAT EVENING AND THE ISOLATED SHOWERS MAY BE SEEN AS FAR
WEST AS ANVIK ON MON.
GIVEN THE RAPID INCREASE IN TEMPERATURES AND THE EXPECTED
LONGEVITY OF THE NOW ABOVE NORMAL TEMPERATURES...RAPID SNOW MELT
IS GOING TO OCCUR AND THIS COULD CAUSE HYDRO PROBLEMS IN THE
SMALLER STREAMS AND RIVERS. THE RMOPS INDICATE WELL ABOVE NORMAL
TEMPERATURES IN THE UPPER LEVEL RIDGE THAT WILL REMAIN CONSTANT
OVER NORTHERN ALASKA THROUGH 360 HOURS.
FLOODING ALONG THE YUKON RIVER REMAINS THE MAIN TOPIC THOUGH. FORT
YUKON HAS BEEN SPARED THUS FAR BUT UNSURE AS TO WHETHER THE MAIN
JAM UPSTREAM HAS RELEASED...ALTHOUGH IT DOES APPEAR THAT AT LEAST
A PORTION HAS DUE TO OBSERVED ICE FLOW.
AS THE UPPER LOW MOVES NORTH ALONG THE ALCAN BORDER...THIS WILL
ALLOW FOR THE LOWER LEVEL WINDS TO TURN MORE SOUTHWESTERLY OVER
MUCH OF NORTHERN ALASKA AND USHER IN MORE MOISTURE. IT DOES NOT
APPEAR THAT THE RH VALUES WILL DROP BACK DOWN TO THE LOW VALUES
THAT WERE SEEN ON WED DUE TO THE INFLUX OF LOW AND MID LEVEL MOISTURE.
&&
.FIRE WEATHER...THE UPPER LEVEL RIDGE BUILDING IN FROM THE EAST
WILL CONTINUE TO DRY THINGS OUT OVER NORTHERN ALASKA.
HOWEVER...THROUGH AT LEAST THE WEEKEND THUNDERSTORMS DO NOT APPEAR
TO BE A MAJOR CONCERN. THERE DOES APPEAR TO BE AN INCREASING
CHANCE FOR THE FAR EASTERN INTERIOR TO POSSIBLY GET A VERY
ISOLATED THUNDERSTORM ON MON THOUGH NORTH OF CHICKEN TO NEAR EAGLE.
&&
.HYDROLOGY...FLOODING FROM THE YUKON RIVER REMAINS TO BE A THREAT
FOR VILLAGES DOWN RIVER FROM FORT YUKON DUE TO RAPIDLY WARMING
TEMPERATURES. RAPID SNOW MELT THAT WILL NOW OCCUR IS ALSO GOING TO
BE ANOTHER PROBLEM THAT COULD EXACERBATE THE FLOODING.

AN UPPER LOW EXTENDING FROM EAST OF THE KAMCHATKA
PENINSULA TO THE NORTHERN BERING SEA WILL GRADUALLY WEAKEN
THROUGH FRIDAY...THEN LIFT NORTHEASTWARD ACROSS THE BEAUFORT
SEA OVER THE WEEKEND. UPPER LEVEL RIDGING WILL BEGIN TO
BUILD OVER THE INTERIOR FRIDAY...BECOMING WELL ESTABLISHED
BY SUNDAY. GFS INTERIOR 850 MB TEMPERATURES ARE RUNNING
WARMER THAN THE ECMWF IN THE EXTENDED PERIOD...BUT EVEN
THE COOLER ECMWF SOLUTION INDICATES HIGH TEMPERATURES
NEAR 70 OR HIGHER OVER MUCH OF THE INTERIOR FROM FRIDAY
INTO MOST OR ALL OF NEXT WEEK. LATEST GEFS ENSEMBLE
MEAN 500 MB CHARTS INDICATE A MEAN RIDGE OVER THE INTERIOR
OUT THROUGH DAY 15. NCEP/CPC CSV2 ENSEMBLE MEAN TEMPERATURE
FORECAST CONTINUES MUCH ABOVE NORMAL MEAN TEMPERATURES
FOR MOST OF NORTHERN ALASKA FOR THE NEXT 2 WEEKS.
A 1004 MB LOW NEAR OF ST LAWRENCE ISLAND WILL WEAKEN TO
A 1008 MB LOW LOW SOUTH OF CAPE NAVARIN BY THURSDAY.
MAINLY SCATTERED SHOWERS OR AREAS OF RAIN OVER THE
WEST COAST TONIGHT AND THURSDAY...SHOWER ACTIVITY
DECREASING THURSDAY. ISOLATED AFTERNOON AND EARLY EVENING
RAIN SHOWERS OVER PARTS OF THE INTERIOR WEDNESDAY AND
THURSDAY...THIS WILL LIKELY BE LOW TOP CONVECTION WITH
CAPES LESS THAN 100 J/KG...LIFTED INDEXES BL TO 500 MB DO NOT
GET MUCH LOWER THAN +2 TO +4. SURFACE LIFTED INDEXES SHOW
LARGER NUMBERS AND SUGGEST LOWER TOP CONVECTION...SOME
ISOLATED CONTOURS OF 100 J/KG. THIS MAY BE ENOUGH FOR
SOME ISOLATED THUNDERSTORMS OVER THE SOUTHERN UPLANDS IN THE
EASTERN INTERIOR...BUT WOULD NOT EXPECT MORE THAN A FEW
CELLS. SCATTERED RAIN/SNOW SHOWERS TONIGHT OVER THE WESTERN
ARCTIC COAST AND WESTERN INTERIOR ARCTIC SLOPE/BROOKS RANGE
TONIGHT...A CHANCE OF RAIN OVER THE WESTERN INTERIOR ARCTIC
SLOPE/BROOKS RANGE THURSDAY.
