NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
642 AM AKDT SAT JUL 7 2012

.SYNOPSIS...
ALOFT...
THE DEEP LOW IN THE GULF OF ALASKA WILL EXPAND NORTHWARD INTO THE
INTERIOR SUN THROUGH TUE...AND MAY PERSIST LONGER. THE RIDGE FROM
NW CANADA ACROSS NE ALASKA WILL MOVE EAST THROUGH TUE. THIS MEANS
CONDITIONS WILL COOL SUN THROUGH TUE.

MODERATE TO STRONG INSTABILITY AND INCREASING MOISTURE WILL ALLOW
ISOLATED OR GREATER THUNDERSTORMS ACROSS THE INTERIOR TODAY AND
SUN.

A SERIES OF SHORT WAVE TROUGHS MOVING NW ACROSS NORTHERN ALASKA
REMAIN THE MAIN WEATHER FEATURES TO FOCUS CONVECTION.
THE 1ST SHORT WAVE FROM NORTON SOUND TO ARCTIC VILLAGE WILL
DISSIPATE OVER NW ALASKA TODAY. EXPECT SCATTERED PM THUNDERSTORMS
ALONG AND NORTH OF THIS.
THE 2ND SHORT WAVE NOW OVER THE SE INTERIOR OF ALASKA WILL MOVE TO
DENALI TO EAGLE BY 4PM SAT AND TO MCGRATH TO BETTLES BY 4PM SUN.
THIS WILL ADD MORE MOISTURE AND HAVE SCATTERED THUNDERSTORMS AHEAD
OF IT.
THE 3RD SHORT WAVE NOW OVER THE GULF OF ALASKA WILL MOVE TO THE
EASTERN ALASKA RANGE BY 4AM SUN AND TO DENALI TO ARCTIC VILLAGE BY
4PM SUN...AND TO MCGRATH TO BETTLES BY 4AM SUN. PRECIPITABLE
WATER LEVELS WILL RISE TO ABOVE ONE INCH AHEAD OF THIS ALONG WITH
VERY UNSTABLE CONDITIONS AND EXPECT WIDESPREAD SHOWERS WITH HEAVY
RAIN AND SCATTERED EMBEDDED THUNDERSTORMS. CONDITIONS DRY AND COOL
SIGNIFICANTLY SE OF THIS TROUGH.

850 MB TEMPERATURES WILL BE 1-2C WARMER TODAY THAN FRI ACROSS
NORTHERN ALASKA SO SURFACE TEMPERATURES TODAY SHOULD BE IN THE
50S AND 60S ALONG THE COAST AND 70S AND LOW 80S INLAND.
TEMPERATURES WILL REMAIN WARM SUN EXPECT THE SE INTERIOR WHERE
TEMPS WILL COOL SIGNIFICANTLY SUN. ON MON MOST OF THE INTERIOR
WILL SEE COOLING.

SURFACE...
STRONG HIGH PRESSURE STRETCHING FROM NORTH OF THE ARCTIC COAST TO
THE NORTHERN BERING SEA WILL PERSIST THROUGH MON. THIS WILL CAUSE
EAST WINDS TO CONTINUE ALONG THE ARCTIC COAST AND NW WINDS ALONG
THE WEST COAST. THIS WILL ALSO CAUSE COASTAL STRATUS AND FOG TO
REMAIN OVER THOSE AREAS.

A WEAK THERMAL LOW PRESSURE OVER THE INTERIOR OF
ALASKA WILL STRENGTHEN SUN AND MOVE OVER THE BROOKS RANGE AND WEST
COAST MON CAUSING WINDS T0 INCREASE ALL AREAS.

A SURFACE RIDGE BUILDING OVER THE COPPER BASIN SAT NIGHT AND SUN
WILL CAUSE GAPS FLOW WINDS THROUGH ALASKA RANG PASSES TONIGHT AND
SUN.

&&

.DISCUSSION...MODELS INITIALIZE WELL AND SHOW SIMILAR SOLLUTIONS
IN THE SHORT RANGE. MUCH UNCERTAINTY BEYOND TUE.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE

&&

.FIRE WEATHER...
TODAY SHOULD SEE SIGNIFICANT NUMBER OF LIGHTNING STRIKES WITH
WELL OVER 1000 EXPECTED. SUN SHOULD HAVE ALMOST AS MANY BUT MORE
RAIN AS WELL.

&&

.HYDROLOGY...
STILL EXPECT 1-1.5 INCH RAIN TONIGHT AND SUN IN ALASKA RANGE
MOVING TO WESTERN INTERIOR SUN. NEED TO WATCH FOR SMALL STREAM
FLOODING IN ALASKA RANGE STARTING LATE TONIGHT.

TANANA RIVER REMAINS HIGH BUT IS NOW DROPPING.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
NONE.
