.DISCUSSION...

SURFACE HIGH PRESSURE OVER THE SITE WEDNESDAY MORNING WILL MAKE FOR
NEARLY CALM WINDS EARLY THAT WILL SHIFT TO SOUTHEASTERLY AT AROUND 5
MPH BY IGNITION. LOOK FOR DEVELOPING SURFACE LOW PRESSURE OVER WYOMING
TO GRADUALLY INCREASE THOSE SOUTHEASTERLY WINDS THROUGH THE DAY...WITH
10 TO 15 MPH EXPECTED BY LATE AFTERNOON. THERE IS A VERY SLIGHT
CHANCE OF AN EVENING SHOWER OR THUNDERSTORM WEDNESDAY...BUT WE EXPECT
STORMS TO REMAIN NORTHWEST OF YOUR SITE.
