DISCUSSION
WEATHER PATTERN OVERVIEW:
THE FORECAST BEGINS TODAY WITH UPPER LEVEL NORTHWEST FLOW WITH A
WARMING TREND CONTINUING INTO TUESDAY.
A COLD FRONTAL PASSAGE LATE TUESDAY WILL LEAD TO EVENING
THUNDERSTORMS, AND CONTINUED SHOWERS AND POTENTIAL THUNDER INTO
WEDNESDAY. AT THIS TIME, HREF IS SHOWING A FEW STORMS IN THE NW
FLOW COULD BRING WIND GUSTS OF 60-65 MPH AND LARGE HAIL. SPC HAS
UPGRADED THE NE TWO-THIRDS OF THE CWA TO A MARGINAL RISK OF SEVERE
THUNDERSTORMS. THESE LOOK TO MAINLY OCCUR FROM 4 PM-9 PM. WITH
THE JET STREAM OVERHEAD OF THESE STORMS, IT WON'T TAKE MUCH TO
GET A GUST TO 60 MPH.
THERE COULD BE A MINOR CONCERN FOR FIRE WEATHER ISSUES IN THE
SOUTHWEST ZONES LATE TUESDAY BUT FUELS HAVE BEEN TOO GREEN LATELY
FOR MAJOR CONCERNS.
INCREASING WEST WINDS BEHIND THE FRONT MAY ALSO NECESSITATE THE
A LAKE WIND ADVISORY FOR FORT PECK LAKE.
WEDNESDAY'S STORMS COULD BE SIMILAR AS THIS W-NW FLOW IS QUICK.
WINDS COULD BE THE BETTER THREAT AT THIS POINT. (HREF NOT ABLE TO
SHOW THIS YET)
A QUIET PERIOD CAN BE EXPECTED THURSDAY-FRIDAY BUT AN UPPER TROUGH
MOVES IN FROM THE PACIFIC NW THIS WEEKEND THAT LOOKS TO BRING
ANOTHER ROUND OF THUNDERSTORMS.
FORECAST CONFIDENCE & DEVIATIONS:
POPS THROUGH TUESDAY WERE BLENDED WITH THE LATEST CAMS. NBM HAS
BEEN TOO DRY LATELY WITH THIS CYCLONIC NW FLOW.
THE REST OF THE FORECAST USED THE NBM. TFJ
AVIATION
UPDATED: MONDAY JUNE 15 AT 2010Z.

DISCUSSION: SCATTERED CUMULUS CLOUDS SHOULD LINGER INTO THE

ISOLATED SHOWERS THAT LINGER INTO TUESDAY. A BETTER CHANCE OF
SHOWERS/THUNDERSTORMS MOVE IN LATE TUESDAY WITH A GOOD CHANCE OF
SEVERE WIND GUSTS.

FROM THE WEST LATER TUESDAY. TFJ
