DISCUSSION
AREAS EAST OF THE JAMES RIVER WILL HAVE WINDS OUT OF THE NORTHEAST
THIS MORNING TURNING TO BE FROM THE EAST SOUTHEAST THIS AFTERNOON
AND EVENING. THESE WINDS COULD GUST UP AROUND 15 TO 20 MPH. THE
MINIMUM RELATIVE HUMIDITY THIS AFTERNOON WILL BE BETWEEN 38 TO 50
PERCENT OVER THIS AREA.
AREAS TO THE WEST OF THE JAMES RIVER WILL SEE EASTERLY WINDS THIS
MORNING TURN TO BE FROM THE SOUTHEAST THIS AFTERNOON AND EVENING.
THESE WINDS WILL GUST A BIT STRONGER IN THE AFTERNOON THAN AREAS TO
THE EAST, WITH GUSTS OF 20 TO 35 MPH. THE STRONGEST OF THESE GUSTS
WILL BE IN AREA WEST OF THE MISSOURI RIVER. WHILE THESE STRONGER
WINDS DO RAISE SOME FIRE WEATHER CONCERNS, THE MOISTURE MOVING INTO
THIS AREA WILL HELP TO EASE THE CONCERNS SLIGHTLY. THE MINIMUM
RELATIVE HUMIDITY THIS AFTERNOON WILL BE BETWEEN 30 TO 45 PERCENT.
IT MIGHT BE HARDER FOR SOMETHING TO IGNITE IN THESE CONDITIONS, BUT
IF IT DOES, THAN THE STRONGER WINDS COULD MAKE IT DIFFICULT TO
CONTROL OR SUPPRESS.
THERE ARE LOWER CHANCES FOR SHOWERS AND STORMS TO FORM THIS
AFTERNOON THROUGH THE OVERNIGHT HOURS DUE TO THE WARMER TEMPERATURES
MAKING IT HARDER FOR THEM TO DEVELOP AND STAY ALIVE. THERE COULD BE
SOME SHOWERS AND STORMS TRY TO DEVELOP AND THEN DIE OFF FAIRLY
QUICKLY, CREATING PULSE SHOWERS AND STORMS. THESE STORMS COULD HAVE
DRY LIGHTNING DEPENDING ON IF THE RAIN REACHED THE GROUND OR NOT AS
WELL AS SOME GUSTY WINDS AS THE STORMS DIE OFF.
