..SYNOPSIS
UPPER-LEVEL RIDGING WILL CONTINUE TO BUILD ACROSS THE WESTERN CONUS
AS AN UPPER LOW TRAVERSES THE CANADIAN PRAIRIES, PERMITTING STRONG
NORTHWESTERLY FLOW TO OVERSPREAD THE NORTHERN PLAINS. AHEAD OF AN
APPROACHING COLD FRONT, DAYTIME HIGH TEMPERATURES WILL REACH 90+
DEGREES F AS RH VALUES QUICKLY DECLINE TO LESS THAN 20% AND
WEST-NORTHWESTERLY WINDS INCREASE TO 15-20 MPH. THE AFOREMENTIONED
COLD FRONT WILL ENTER MONTANA SOMETIME DAY 2/THURSDAY AFTERNOON,
THOUGH APPROXIMATE TIMING IS UNCERTAIN GIVEN VARYING MODEL
SOLUTIONS. AS THE FRONT PASSES, WINDS WILL SHIFT TO BROADLY
NORTHERLY AT 15-25 MPH (GUSTS OVER 30 MPH) FOR A COUPLE OF HOURS
WHILE RH INCREASES OVERNIGHT. ELEVATED HIGHLIGHTS HAVE BEEN
INTRODUCED ACROSS PORTIONS OF THE COLORADO PLATEAU INTO THE NORTHERN
PLAINS WHERE ERCS WILL RANGE FROM THE 80-95TH PERCENTILE, AND NDVI
PORTRAYS A SIGNIFICANT 30-DAY DECREASE IN LIVE GREEN VEGETATION.
PROLONGED ABOVE NORMAL TEMPERATURES, A DRY BOUNDARY LAYER, AND
BRIEFLY BREEZY WINDS MAY ENCOURAGE LOCALLY ELEVATED FIRE CONDITIONS
TO EMERGE ACROSS THE CALIFORNIA VALLEYS AND ADJACENT HIGHER TERRAIN
WHERE WIDESPREAD ERCS EXCEED THE 90TH PERCENTILE.
