anomalously chilly air will prevail over the region through
friday as an upper low lingers over hudson bay. this low brought
showers and chilly air to the region yesterday behind a cold
front. the cold air will bring the likelihood of frost formation
tonight especially north of highway 30 as temperatures drop
into the 30s. highs both today and thursday will only be in the
50s. pondered headlines for this upcoming night with surrounding
offices - the consensus was to defer any headlines to the
dayshift. the possibility, extent and amount of cloud formation
tonight under the high-based subsidence inversion will make low
temperature forecasts challenging.
a milder and more unsettled pattern is farther ahead into early
next week as the upper level trof over the great lakes region
shifts east and as the upstream flow becomes more zonal. ample
upper level disturbances will travel east in the upper flow and
bring chances for showers. at this time, severe weather chances
appear low.

a low level trough axis shifting across the southern great
lakes has resulted in better low level fgen forcing slipping
south of the terminals with an increase in low level dry air
advection. the potential of measurable rain has come to an end
at the terminals this morning. after some brief clearing or
partial clearing this morning, additional mid level cloud cover
is expected today as a series of sheared short waves approach in
westerly flow regime associated with upstream positively tilted
upper trough. in addition the mid clouds, some sct-bkn vfr low
clouds are possible this afternoon. a weak westerly gradient
will be maintained today allowing some northwest winds around 10
knots, eventually becoming light and variable early this
evening with loss of daytime mixing and the approach of low
level ridge axis from the mid ms rvr valley.
