...HOT AND DRY CONDITIONS EXPECTED AGAIN TODAY...

.DISCUSSION...
A STRONG UPPER LEVEL RIDGE OVER THE FOUR CORNERS WILL COMBINE WITH
A SURFACE THERMAL TROUGH OVER THE IDAHO / OREGON BORDER THIS AFTERNOON. THIS
WILL BRING ANOTHER HOT AND DRY DAY TODAY. HIGH LEVEL MOISTURE WILL MAKE
ITS WAY ACROSS THE BURNS BLM BUT ANY RISK OF CONVECTION WILL BE LIMITED
TO NORTH OF BURNS TODAY.  CLOUDS WILL REMAIN OVER THE AREA TONIGHT BRINGING
POOR RH RECOVERY TO ALL AREAS. A PACIFIC COLD FRONT WILL BEGIN TO MOVE INTO
THE PACIFIC NORTHWEST TUESDAY AFTERNOON BUT ONCE AGAIN THE MAIN THREAT OF
CONVECTION IS EXPECTED TO BE MORE IN IDAHO. THE MAIN CONCERN FOR TUESDAY
AFTERNOON WILL BE STRONG AND POST FRONTAL GUSTY WINDS.
