.DISCUSSION...

There is a 30% chance of very light and localized rain showers moving
through the fire from 1100 to 1400 LT today just ahead of a cold
front moving southeast across the Northland today. After a two
to three hour break, scattered thunderstorms may (40% chance)
move near the fire site in the late afternoon and early evening
hours today. Isolated strong thunderstorms with localized erratic
wind gusts up to 45 mph and small hail possible in the strongest
storms. Localized rainfall amounts of 0.10-0.25" are likely with
any showers or storms, but the scattered nature of the rain could
lead to areas seeing less than a tenth of an inch. Winds start out
southwesterly from 5 to 8 mph ahead of the front during the
morning, but quickly shift westerly and increase in speed by early
afternoon, and then further shift northwesterly in the mid- to
late afternoon with 20 ft winds increasing to around 15-18 mph.
Minimum RH in the afternoon drops to 45-50 percent, but
showers/storms could lead to localized increases in humidity if
they move overhead.
