20-FOOT WIND FORECAST OF 'LIGHT WINDS' INDICATES MAINLY
TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
DISCUSSION
A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS TODAY
IN THE WHITE MOUNTAINS, OTHERWISE DRY CONDITIONS PREVAIL TODAY AND
CONTINUE AREA-WIDE THROUGH THE WORK WEEK. WINDS THIS WEEK WILL
FOLLOW DIURNAL TRENDS WITH TYPICAL AFTERNOON BREEZES. A WEATHER
SYSTEM THIS WEEKEND WILL RESULT IN INCREASED SOUTH TO SOUTHWEST
WINDS, ALONG WITH PRECIPITATION CHANCES. THE COMBINATION OF THE GUSTY
WINDS AND LOW RELATIVE HUMIDITY MAY RESULT IN ELEVATED FIRE WEATHER
CONCERNS THIS WEEKEND, THOUGH AN INCREASE IN MOISTURE MAY MITIGATE
CRITICAL RH VALUES. THIS IS SOMETHING WE'LL BE MONITORING THROUGH
THE COURSE OF THE WEEK. MEANWHILE, MINIMUM RH VALUES 10 TO 20
PERCENT IN THE VALLEYS AND 20 TO 40 PERCENT IN THE MOUNTAINS TODAY,
LOWERING BACK DOWN TO THE HIGH SINGLE DIGITS TO TEENS AREAWIDE
WEDNESDAY THROUGH FRIDAY.
