.DISCUSSION...
MODELS IN GOOD AGREEMENT THROUGH END OF THE WEEK WITH A 575 TO 585
DM BLOCKING HIGH PRESSURE MEANDERING OVER NORTHERN ALASKA. MINOR
HEIGHT FALLS IN EASTERN ALASKA AS SHORTWAVE CONTINUES TO MOVE
SOUTH AND WEST AND AS THE HIGH PRESSURE NUDGES TO THE NORTHWEST.
RECORD OR NEAR RECORD HEAT ON TAP FOR MUCH OF NORTHERN ALASKA
THROUGH MID WEEK AND WELL ABOVE NORMAL TEMPERATURES THROUGH THE
END OF THE WEEK. A SHORTWAVE ROTATING NORTHWESTWARD INTO THE
SOUTHERN INTERIOR FRIDAY WILL PROVIDE AN OPPORTUNITY FOR INCREASED
CLOUD COVER AND POTENTIAL FOR ISOLATED THUNDERSTORMS. ANOTHER
SHORTWAVE MOVES INTO THE SOUTHERN INTERIOR ON SUNDAY WITH THE
POTENTIAL FOR ISOLATED THUNDERSTORMS. INCREASED CLOUD COVER AND
SLIGHTLY COOLER TEMPERATURES WILL IMPROVE MINIMUM RH VALUES
HOWEVER THAT WILL BE OFFSET BY THE POTENTIAL FOR LIGHTNING CAUSED
FIRES.
RELATIVE MEASURES OF PREDICTABILITY ARE HIGH AND CONTINUE TO BE
HIGH WHICH LEADS TO A HIGH FORECAST CONFIDENCE.
COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
