for the most part the forecast is still on track. one thing that
has slightly changed is the forecasted precipitation amounts
with values trending lower over the last several model runs.
the current thinking is the disturbance sliding a bit further
east than previous runs. the current precipitation forecast has
generally around 0.50" for most locations northwest of the i-69
corridor and slightly higher amounts towards the 0.75" mark.
there is likely to be locally higher amounts especially where
any thunderstorms develop.
otherwise, still looking at warming gradually through the
weekend and increasing moisture today into saturday with dew
point values getting into the upper 50s and even mid to upper
60s in the southeastern parts of the cwa. this will make for
humid conditions and make for generally uncomfortable
conditions. the pattern holds fairly steady with bouts of
scattered showers and a few embedded thunderstorms each day into
next week, better chances will be in the afternoon periods
especially for any thunderstorm activity. highs by memorial day
and through next week will get into the lower to mid 80s. air
conditioning use will be on an uptick over the next several
days to help mitigate the impacts of the moist airmass in
place.

vfr conditions expected through 14z for kfwa and 20z fri for
ksbn with an influx of low level moisture pushing northward
associated with a disturbance moving out of the southwest
bringing mvfr cigs. light rain and showers look to make it into
kfwa between 22z fri through 00z sat accompanied by lower ifr
cigs. ksbn cigs lower to ifr cat after 02z sat and rain showers
push into the terminal. there is the possibility for a few
embedded thunderstorms mainly after 02z sat however confidence
is low in timing and coverage. easterly winds becoming gusty
after 12z to 14z with gusts around 25 kts at times.
