SOUTHEAST ALASKA FORECAST DISCUSSION
630 AM AST TUE NOV 13 2007

.SYNOPSIS...
.SHORT RANGE...THE LATEST SATELLITE IMAGERY SHOWS THE PANHANDLE
UNDER MOSTLY CLOUDY SKIES WITH SOME SHOWERS MOVING OVER THE
PANHANDLE. IT IS COLD ENOUGH IN THE NORTHERN AREAS THAT SOME
LIGHT SNOW IS FALLING BUT THINK THROUGH THE MORNING TIME FRAME
THESE SNOW SHOWERS WILL BECOME MIXED WITH RAIN AND BECOME ALL
RAIN BY THE AFTERNOON. THERE WILL NOT BE THAT MUCH ACCUMULATIONS
WITH THESE SNOW SHOWERS. THE WINDS ARE RELATIVELY ON THE LIGHT
SIDE BUT THERE IS SOME STRONGER WINDS IN LYNN CANAL.

RAIN WILL CONTINUE TO INCREASE THROUGH THE DAY OVER THE FORECAST
AREA AS A MODERATE 90KT JET FROM THE SW KEEPS A PERSISTENT
ONSHORE FLOW. ALONG WITH THE ONSHORE FLOW A SURFACE TROF OVER THE
CENTRAL GULF WILL PUSH EAST THROUGH TO DAY AND LIFT OVER THE SE
AK BY THIS EVENING. THIS TROF WILL ENHANCE THE RAIN NEAR PAYA AND
THEY MAY SEE RAIN HEAVY AT TIMES LATER THIS AFTERNOON AND
CONTINUE INTO TONIGHT AS THERE IS STRONG UPPER LEVEL DYNAMICS
ALONG WITH THE JET SUPPORT. THE REST OF THE PANHANDLE WILL
CONTINUE TO SEE LIGHT TO MODERATE RAIN THROUGH TONIGHT. THINK
MOST OF THE PRECIP WILL FALL IN THE LIQUID FORM AS WITH THE FLOW
COMING OFF THE OCEAN TEMPERATURE WILL BE TEMPERATE. PLACES THAT
COULD SEE SOME SIGNIFICANT SNOW WOULD BE ALONG THE HAINES AND
KLONDIKE HIGHWAYS AS THEY WILL REMAIN ON THE COOLER SIDE AND
COULD SEE UP TO 3 INCHES TONIGHT.

THE WINDS OVER THE PANHANDLE WILL INCREASE THROUGH TODAY AS THE
SURFACE MOVES INTO THE EASTERN GULF. WINDS WILL INCREASE TO 20 TO
30 KT OVER THE COASTAL AREAS THROUGH TONIGHT AS THE WINDS OVER
THE INSIDE WILL INCREASE TO 15 TO 25 KT. OVER LAND IT WILL BECOME
BREEZY BY TONIGHT AS THE PRESSURE GRADIENT INCREASES. THE
STRONGEST WINDS WILL UP NEAR PAHN AND PAGY AS WHEN THE TROF LIFTS
INTO CANADA THE SOUTHERLY WINDS WILL RAPIDLY INCREASE WITH A
SURFACE HIGH OVER THE SOUTHERN BC BUILDS OVER THE SOUTHERN AREAS
TONIGHT TO ENHANCE THE PRESSURE GRADIENT. WINDS WILL BE NEAR WIND
ADV BUT ATTM THINK GUSTS WILL BE NEAR 35 MPH BUT IF THE
ORIENTATION OF THE GRADIENT BECOMES MORE OF A SOUTH/NORTH INSTEAD
OF A SE/NW THEN A WIND AVD MAY BE WARRANTED.

.LONG RANGE...THE WEAK LONG WAVE FEATURES IN THE EASTERN PACIFIC
SHOULD SHARPEN THROUGH THE LATER PART OF THE WEEK AS AN UPPER
LEVEL LOW DEEPENS IN THE GULF OF ALASKA AND A RIDGE ALOFT
AMPLIFIES TO THE WEST ALONG LONGITUDE 180. ALTHOUGH MODEL
DIFFERENCES ARE SMALLER DIFFERENCES THAN PREVIOUS CYCLES...THERE
IS STILL DISAGREEMENT ON THE POSITION OF THE UPPER LOW AS WELL AS
THE SPEED AND INTENSITY OF INDIVIDUAL SHORTWAVES ROTATING AROUND
IT. PREFER TO NUDGE THE GFS POSITION MORE TO THE WEST AND SOUTH
WHICH IS CLOSER TO THE ENSEMBLE MEAN.

AT THE SURFACE...A DEEP 960 MB LOW IS EXPECTED TO DEVELOP SOUTH
OF THE PANHANDLE BRINGING GALES TO THE OUTER COAST AND SOUTHERN
INSIDE WATERS THU NIGHT. NORTHEASTERLY OFFSHORE WINDS WILL
STRENGTHEN IN THE NORTHERN INNER CHANNELS. THE LOW SLOWLY FILLS
AS IT CURVES NORTHWESTWARD FRI. ALTHOUGH CLOUDS WILL EXTEND OVER
MOST OF PANHANDLE...PRECIPITATION WILL BE CONFINED PRIMARILY TO
SOUTHERN SECTIONS DUE TO DOWNSLOPE DRYING FROM THE NORTHEAST
OFFSHORE FLOW.
