AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
238 PM MDT TUE JUL 28 2015

.SHORT TERM...VALID FOR WED AND THU...

WINDS WILL TREND DOWN QUICKLY THIS EVENING WITH A DRY AND WARMER
PATTERN DEVELOPING FOR THE REST OF THE WEEK.

WINDS HAVE GUSTED AROUND 60 MPH SINCE MID MORNING OVER SOUTHEAST
MONTANA INCLUDING THE BAKER...MILES CITY AND EKALAKA AREAS. WE
HAVE PROBABLY SEEN THE STRONGEST WIDESPREAD WINDS OF THE DAY
ALREADY AND SHOULD SEE A SLOW WEAKENING TREND FOR THE REST OF THE
AFTERNOON...WITH A QUICK RELAXING OF REMAINING WINDS BY SUNSET.
KEEPING THE HIGH WIND WARNING GOING AS A FEW LIGHT SHOWERS
CROSSING EASTERN MONTANA COULD PUSH DOWN A STRONGER WIND GUST
THROUGH THE EARLY EVENING HOURS. ANY SHOWERS WILL DISSIPATE
QUICKLY THIS EVENING AS WELL LEAVING A MOSTLY CLEAR OVERNIGHT
ACROSS THE FORECAST AREA.

A RETURN TO A TYPICAL SUMMERTIME WEATHER REGIME BEGINS TOMORROW.
FLOW ALOFT BECOMES LESS AMPLIFIED TOMORROW AND A DRY WEST TO
NORTHWEST FLOW WILL PREVAIL INTO THE WEEKEND. EXPECT TEMPERATURES
TO JUMP INTO THE 80S FOR WEDNESDAY AND INTO THE LOWER 90S FOR
THURSDAY UNDER MOSTLY SUNNY SKIES. CHAMBERS

.LONG TERM...VALID FOR FRI...SAT...SUN...MON...TUE...

SUMMERTIME RIDGING...WHICH HAS BEEN UNUSUALLY ABSENT THE LAST FEW
WEEKS...WILL RETURN TO THE FORECAST BY THE TIME THE WEEKEND
ARRIVES. 500MB FLOW WILL BE OUT OF THE WEST NORTHWEST WITH RISING
HEIGHTS AS A RIDGE AXIS STRENGTHENS IN EASTERN WASHINGTON STATE.
THIS SHOULD GIVE OUR FORECAST AREA SOME OF THE WARMEST
TEMPERATURES IN THE PAST TWO WEEKS WITH MOST LOCATIONS IN THE MID
TO UPPER 90S AWAY FROM THE MOUNTAINS ON SATURDAY. MONSOONAL
MOISTURE SHOULD WRAP AROUND THE RIDGE LATE IN THE WEEKEND AND
INCREASE SHOWER AND THUNDERSTORM CHANCES THROUGH THE REMAINDER OF
THE PERIOD. THE INCREASING MOISTURE SHOULD COOL TEMPERATURES
SLIGHTLY BUT WITH OUR AREAS PROXIMITY TO THE RIDGE
AXIS...TEMPERATURES WILL BE WARMER THAN NORMAL OUTSIDE ANY
BACKDOOR COLD FRONT LATE IN THE EXTENDED. DOBBS
