NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
618 AM AKDT SUN JUN 24 2012

.DISCUSSION...
TODAY WILL BE THE LAST DAY OF THE WARM SPELL OVER MOST OF THE
CNTRL/ERN INTERIOR. AN UPPER LOW OVER THE SRN BERING SEA WILL PUSH
EWD TO THE AK PEN BY MON AFTN AND INTO THE NRN GLFAK BY TUE AFTN.
THIS WILL RESULT IN LOWERING HEIGHTS ALF AND 850 MB TEMPS COOLING
TO NEAR NORMAL.

THERMAL TROUGH WITH UNSTABLE AIR MASS TODAY EXTENDS E-W FROM THE
UPR YUKON VALLEY TO SELAWIK. NWD MOVING SHORT WAVE WILL PROVIDE
UPPER LEVEL FORCING TO ENHANCE TSTM DEVELOPMENT. TSTM ACTIVITY
MON WILL BE LIMITED MAINLY TO THE BROOKS RANGE...ERN INTERIOR
ARCTIC PLAIN AND IN THE ERN INTERIOR NEAR THE ALCAN BORDER.
RAPID STABILIZATION IS EXPECTED BEHIND THE SHORT WAVE. THE MORNING
PAFA RAOB HAS 1300 J/KG OF CAPE AND A -5 LI BUT THIS WILL LIKELY ALL
GO AWAY BY THIS AFTERNOON.

RAIN OR SHOWERS WILL SPREAD NWD ACROSS THE W COAST AND WRN INTERIOR
TODAY AND TONIGHT WITH A NWD MOVING FRONT. SHOWERS WILL BECOME
SCATTERED BY MON.

GFS/ECMWF OPERATIONAL RUNS AND THEIR ENSEMBLE MEANS ARE IN
GOOD AGREEMENT IN THE MEDIUM RANGE...KEEPING A MEAN UPPER LOW OR
TROUGH OVER THE NRN GLFAK AND MAINLY E TO SE FLOW ALF OVER MUCH OF
THE INTERIOR WITH HEIGHTS AND 850 MB TEMPS MAINLY NEAR TO A BIT BELOW
NORMAL. THIS SHOULD BE A GOOD PATTERN FOR SHOWERS AND ISOLATED
THUNDERSTORMS WITH THE UPPER FLOW BRINGING IN MORE MOISTURE.
SEVERAL WEAK SHORT WAVES WITH MOISTURE SURGES LIKELY TO TRANSIT
WWD ACROSS THE CNTRL/SRN INTERIOR...RAISING THE POTENTIAL FOR
SIGNIFICANT PRECIP FROM SHOWERS. RECENT RUNS OF THE GFS HAVE BEEN
PAINTING SOME SIGNIFICANT QPFS AT TIMES ALONG THE AK RANGE AND IN
THE SE INTERIOR.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE

&&

.FIRE WEATHER...
LOCAL WIND GUSTS TO 25 MPH EXPECTED THIS AFTN AND EVE IN
AKZ219-220-221-222-223 AND IN AK RANGE PASSES. MIN RH
LIKELY TO BE BELOW 30 PERCENT IN OVER MUCH OF THE INTERIOR
N OF THE RANGE. RED FLAG CONDITIONS FOR WIND GUSTS WITH RH
BELOW 30 PERCENT POSSIBLE IN ZONES 218-219-220-221-222-223.

&&

.HYDROLOGY...
FREEZING LEVEL NEAR 10000 FT ALONG THE ERN AK RANGE TODAY...BUT
WILL DROP TO AROUND 9000 FT MON. HIGH ELEVATION SNOWMELT AND
GLACIAL SNOWMELT CONTINUING OVER THE ERN AK RANGE. TANANA RIVER
WILL CONTINUE TO RISE VERY SLOWLY BUT REMAINING BELOW FLOOD
STAGE. FORECAST STAGE AT FAIRBANKS IS ABOUT 21.8 FT BY EARLY WED.
THERE WILL BE INCREASED POTENTIAL FOR HEAVY SHOWERS AS THE
E TO SE UPPER FLOW SETS IN OVER THE CNTRL/SERN INTERIOR AREAS.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY FOR PKZ210-PKZ220-PKZ225.

BRISK WIND ADVISORY FOR PKZ245.
