.DISCUSSION...
Wind gusts of 25-35 mph Thursday, along with RH values as low
as 35-45% Thursday afternoon...
Southerly winds increase to 10-15 mph with gusts possibly as
high as 25-35 mph Thursday afternoon, especially in the north-
south oriented valleys. RH values are currently expected to drop
into the 35-40% range, and could potentially push into the
30-35% range in a few areas in the lower-end of guidance is
correct. The greatest overlap of low RH and gusty winds looks to
be mainly from the Capital District north and east. Most areas
have seen little to no rain over the past several days.
RH values should begin to rise Thursday late afternoon into
early evening as dew points rise ahead of a cold front. This
cold front will bring a widespread wetting rainfall Thursday
evening into Friday morning.
