...PORTIONS OF THE NORTHERN/CENTRAL ROCKIES...
NO MAJOR CHANGES ARE MADE TO THE ONGOING ISOLATED DRY-THUNDER AREA.
CONVECTION SHOULD INCREASE IN COVERAGE THIS AFTERNOON...AS WEAK
MID-LEVEL IMPULSES CROSS THE REGION AND OROGRAPHIC CIRCULATIONS
INTENSIFY. REGIONAL 12Z RAOBS DEPICT FAVORABLE PW VALUES /E.G.
AROUND 0.6-0.7 INCHES AT BOI...SLC...GJT/...SUCH THAT ISOLATED DRY
LIGHTNING STRIKES SHOULD BE REALIZED LATER TODAY. FUELS ACROSS MUCH
OF THE REGION REMAIN QUITE DRY...FURTHERING THE POTENTIAL FOR

...SYNOPSIS...
A WEAK UPPER LEVEL IMPULSE WILL MOVE ACROSS PORTIONS OF THE NORTHERN
ROCKIES TODAY. MEAGER MIDLEVEL MOISTURE BENEATH THE LARGER-SCALE
UPPER RIDGE WILL BE SUFFICIENT FOR ISOLATED THUNDERSTORMS DURING THE
AFTERNOON FROM NE UT/NW CO NORTHWARD THROUGH WRN WY AND INTO SW MT
AND ADJACENT PARTS OF CNTRL/ERN ID. PW VALUES WILL BE QUITE
LOW...GENERALLY BETWEEN 0.5 AND 0.7 INCHES WITH A DEEP...DRY
SUB-CLOUD LAYER. THIS WILL PROMOTE DRY THUNDERSTORM POTENTIAL OVER
DRY FUELS. ELSEWHERE...FIRE WEATHER CONCERNS ARE NOT ANTICIPATED.
