AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
211 PM CDT THU JUL 30 2015

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 206 PM CDT THU JUL 30 2015

THE PRIMARY WEATHER FEATURE FOR THE SHORT TERM WILL BE LARGE AND DRY
SURFACE HIGH PRESSURE ACROSS THE HIGH PLAINS OF MONTANA AND WYOMING.
FLOW AROUND THE HIGH SHOULD CONTINUE TO KEEP MOISTURE LOW WHILE
NORTHWEST FLOW ALOFT OVER THE ROCKIES SHOULD MAINTAIN A WARM
ELEVATED MIXED LAYER ACROSS WESTERN NORTH DAKOTA. THIS WILL MAINTAIN
THE DRY WARMING TREND WITH MAINLY CLEAR SKIES.

FOR FIRE WEATHER...GRASSES CONTINUE TO CURE ACROSS WESTERN NORTH
DAKOTA. HIGHS IN THE 80S TO LOWER 90S WILL KEEP THIS TREND. WHILE
AFTERNOON HUMIDITY WILL FALL INTO THE UPPER TEENS AGAIN FRIDAY AND
SATURDAY WINDS SO FAR REMAIN BELOW SPEEDS THAT WOULD RAISE
CONCERNS.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 206 PM CDT THU JUL 30 2015

AN UPPER LEVEL RIDGE WILL BUILD ACROSS THE WESTERN CONUS THROUGH
THE REST OF THE WEEK. THIS WILL KEEP THE MAJORITY OF NORTH DAKOTA
DRY THROUGH THE NEXT SEVERAL DAYS...WITH TEMPERATURES NEAR NORMAL
(80S TO LOW 90S). SEVERAL FAST MOVING SHORT WAVE TROUGHS
TRAVERSING THE RIDGE MAY BRING SOME LIGHT PRECIPITATION TO THE
AREA THIS WEEKEND...HOWEVER THE BETTER CHANCES HOLD OFF UNTIL
AROUND TUESDAY NEXT WEEK.

DRY CONDITIONS ACROSS SOUTHWEST NORTH DAKOTA MAY LEAD TO ELEVATED
FIRE WEATHER CONCERNS THIS WEEKEND. RH VALUES COULD DROP INTO THE
LOW TEENS ACROSS THE SOUTHWEST. HOWEVER...WINDS SHOULD BE FAIRLY
LIGHT.
