DISCUSSION
UPDATED TO SHOW INCREASED CONFIDENCE FOR GUSTY SOUTHWESTERLY
WINDS SATURDAY NIGHT.
SATURDAY WE ARE STILL HIGHLIGHTING HOT AND DRY CONDITIONS, WITH
AN EASTERLY WIND COMPONENT. THE SURFACE INVERSION IS CURRENTLY
BREAKING WITH WINDS INCREASING SLIGHTLY THROUGH THE AFTERNOON, LIKELY
GUSTING 15 MPH ALONG THE RIDGES. TEMPS WILL REACH THE MID TO UPPER
80S, WITH RH DROPPING INTO THE LOW 20S.
INCREASED CONFIDENCE FOR ELEVATED WINDS TONIGHT:
NEAR 10 PM SATURDAY NIGHT, THERE IS INCREASED CONFIDENCE FOR A
SOUTH-SOUTHWEST SURGE OF ELEVATED WINDS. ONCE THIS SURGE HITS,
EXPECT A FEW HOURS OF GUSTY 15 TO 25 MPH WINDS, WITH THE HIGHEST WINDS
ALONG EXPOSED RIDGES. WE WILL SEE THESE WINDS DECREASE LATER
SUNDAY MORNING BUT REMAIN SOUTHWESTERLY. THERE ARE A FEW
OBSERVATIONS SITES TO THE SOUTHWEST OF NENANA SO WE SHOULD BE ABLE
TO SEE THESE SOUTHWEST WINDS FORM.
WE REMAIN INCREASINGLY CONFIDENT FOR SLOW MOVING THUNDERSTORMS
SUNDAY INTO MONDAY PUSHING INTO THE INTERIOR. KEEP A SHARP LOOKOUT
FOR VIRGA AND GUSTY/ERRATIC WINDS.
