SPOT FORECAST FOR PIN OAK PR...MNDNR
NATIONAL WEATHER SERVICE LA CROSSE WI
741 AM CDT TUE APR 24 2012

FORECAST IS BASED ON IGNITION TIME OF 1300 CDT ON APRIL 24.
IF CONDITIONS BECOME UNREPRESENTATIVE CONTACT THE
NATIONAL WEATHER SERVICE IN LA CROSSE.

.DISCUSSION...LOOK FOR CLOUDS TO GRADUALLY DECREASE TODAY WITH
A RIDGE OF HIGH PRESSURE OVER THE IGNITION SITE. DRY AIR
ASSOCIATED WITH THE RIDGE COMBINED WITH DAYTIME HEATING WILL ALLOW
RELATIVE HUMIDITIES TO DROP TO NEAR 35 PERCENT IN THE AFTERNOON.
DUE TO THE RIDGE IN PLACE...PLAN ON LIGHT WINDS. SINCE THE WINDS
ARE LIGHT...SMOKE DISPERSAL WILL NOT BE THE GREATEST...THOUGH
SHOULD IMPROVE SOME IN THE AFTERNOON AS MIXING HEIGHT INCREASES.
CLOUDS WILL INCREASE AGAIN TONIGHT AHEAD OF A LOW PRESSURE SYSTEM
APPROACHING THE AREA FROM THE DAKOTAS. SOME SHOWERS AND A FEW
THUNDERSTORMS COULD MOVE INTO THE IGNITION SITE AFTER
MIDNIGHT...THOUGH BETTER CHANCES ARE WEDNESDAY MORNING. MOST OF
THE PRECIPITATION SHOULD EXIT THE AREA IN THE AFTERNOON...THOUGH A
FEW MORE SHOWERS AND THUNDERSTORMS CANNOT BE RULED OUT WITH THE
LOW PRESSURE SYSTEM STILL NEARBY.
