a dynamic low pressure system exiting the region is resulting in
improving conditions across the area. northerly winds wrapping
around the backside of the departing low will allow cooler,
drier air to filter into the region, keeping temperatures below
normal for the next few days. skies will clear from west to east
this evening, and good radiational cooling will bring overnight
lows in the low to mid 50s. tuesday will be mild with highs in
the mid 70s.
the low-level flow shifts to the southwest again on wednesday,
and warm air advection ahead of the next weather system will
facilitate highs in the upper 70s. showers and storms return
wednesday evening, but with only marginal shear and instability,
severe weather is not expected, although brief heavy downpours
are possible. scattered showers will remain possible thursday
through saturday as a series of shortwaves move through the
region. high pressure builds back into the midwest on sunday and
monday with high temperatures in the mid to upper 80s.

gusty north-northwest winds to begin this forecast period will
become light north this evening with boundary layer decoupling
and an expansive ridge of high pressure building in from the
west. wind gusts at ksbn have reached into the 25 to 30 knot
late this afternoon and these gusts appear to be aided by
passage of marine enhanced boundary. slow progression of upper
level height pattern will make for slow eastward migration of
this ridge axis. position of the ridge axis should be far
enough west to support northwest winds around 10 knots tuesday
afternoon. some higher gusts closer to 20 knots are possible at
ksbn mid-late tuesday afternoon with some potential marine
enhancement once again. otherwise, vfr conditions are expected
this forecast period with vfr low clouds diminishing this
evening.
