Overall this evening the primary forecast focus is on the cold
temperatures predicted for tonight. The PRESSURE GRADIENT is
expected to remain tight overnight due to the RIDGE still well to
the west of the region. This will keep surface winds in the 5 to 10
mph RANGE, which will be more than sufficient to prevent
temperatures from crashing too quickly. However, the magnitude of
the cold advection is such that temperatures should still be able to
drop into the mid to upper 30s across much of the area. Although it
will be quite chilly, FROST is not expected (thus no frost ADVISORY
overnight) due to both expected surface winds and dry airmass in

Based on this, relatively little change has been applied to the
inherited forecast package. Will make a FEW minor tweaks to the MIN
TEMPERATURE forecast based on the latest trends. Did go ahead and
issue the FREEZE WATCH for Friday NIGHT due to increasing confidence
that our first WIDESPREAD freeze will occur by Saturday morning AS
cold high pressure settles directly overhead.
