.PREV DISCUSSION... /ISSUED 253 AM CDT SUN AUG 30 2015/

DISCUSSION...
A SURFACE RIDGE AXIS OVER THE NORTHEAST CWA SHOULD SLIDE OFF TO EAST
THIS MORNING. AM CONCERNED THAT SOME FOG MAY FORM IN ASSOCIATION
WITH THIS RIDGE AXIS...ESPECIALLY AS WINDS TURN MORE TO THE
SOUTHEAST AND ADVECT IN HIGHER DEW POINTS. HAVE ADDED PATCHY FOG TO
THE FORECAST IN THE NORTHEAST FOR NOW. BUT THIS AREA WILL BE WATCHED
FOR THE POSSIBILITY OF DENSE FOG. OTHERWISE...A SURFACE TROUGH WILL
RE-ESTABLISH ITSELF ALONG THE LEE-SIDE OF THE ROCKIES. THIS SURFACE
TROUGH ALONG WITH WARMING 850 MB TEMPS SHOULD HELP HIGH TEMPERATURES
WARM A COUPLE OF DEGREES FROM THE PREVIOUS DAY BOTH TODAY AND MONDAY.

THE UPPER LEVEL RIDGE FROM SOUTHERN NEW MEXICO INTO THE GREAT LAKES
WILL KEEP MOST OF THE SHOWERS AND THUNDERSTORMS TO OUR WEST TODAY.
THE WESTERN SIDE OF THE RIDGE MAY GET KNOCKED DOWN JUST ENOUGH TO
ALLOW SOME SHOWERS AND THUNDERSTORMS INTO THE NORTHWEST CWA MONDAY
THROUGH TUESDAY.

THE FORECAST THEN GOES DRY AGAIN AS THE RIDGE HOLDS STRONG WEDNESDAY
AND THURSDAY. THE WESTERN SIDE OF THE RIDGE WILL WEAKEN AGAIN BY
FRIDAY WHICH WILL ALLOW ADDED SUBTROPICAL MOISTURE ALONG WITH A FEW
UPPER LEVEL SHORT WAVE TROUGHS TO PASS OVER. SO...SHOWER AND
THUNDERSTORMS SHOULD INCREASE AGAIN TOWARDS THE END OF THIS WEEK.

.AMA WATCHES/WARNINGS/ADVISORIES...

OK...NONE.
