a sprawling low level anticyclone, currently centered over the
western/northern great lakes at ~1030 mb, will sink slowly south to
overhead by wednesday, and off to the southeast by thursday and
friday. this will allow our stretch of pleasant weather to persist
through at least friday morning. temperatures will gradually climb,
especially by thursday and friday when increasing southwesterly flow
on the backside of the aforementioned high pressure system will
advect in warmer air. the more dramatic increase in column moisture
appears delayed until later friday and saturday. this incoming high
theta-e air in conjunction with several mid level disturbances
traversing the area in flattened quasi-zonal flow aloft could yield
periodic scattered showers and storms, particularly on saturday with
heavier downpours possible. the bulk of available model guidance
suggests a return to drier wx sunday into early next week in wake of
saturday`s wave, though did retain nbm`s low chance pops given
limited ensemble support for a frontal boundary to linger in the
vicinity.

allow for quiet weather to persist. vfr conditions are expected
through the taf forecast period. winds are coming from the
east/northeast this afternoon at around 10-15 kts; winds are
expected to become light and variable overnight as diurnal
heating diminishes and high pressure drifts overhead.
