IF THEY MANAGE TO STAY TOGETHER FROM NATRONA COUNTY (LOW CONFIDENCE SCENARIO). A NOCTURNAL INVERSION
LOOKS TO SET UP EARLY IN THE MORNING POSSIBLY LIMITING SMOKE DISPERSAL BUT THINGS SHOULD BECOME
BETTER ONCE DIURNAL MIXING STARTS. FRIDAY AFTERNOON WIND GUSTS UP TO 30 MPH LOOKS POSSIBLE AS THE
700MB PRESSURE GRADIENT TIGHTENS FROM THE LOW PRESSURE SYSTEM MOVING ALONG THE CANADIAN BORDER.
THERE ARE SOME THUNDERSTORMS FORECASTED FOR TOMORROW AND BETWEEN 3 AND 6 PM CURRENTLY LOOK TO BE
THE BEST TIMING FOR THOSE SHOWERS TO MOVE OVER THE BINFORD AREA. THE CHANCE FOR WETTING RAIN IS
