The persistent upper level pattern of ridging across the western
CONUS and troughing across the Great lakes and Ohio River Valley
will continue to prevail through the entirety of the forecast
period. This will leave the local area under a dry northwest flow
aloft between the two main upper features. Several shortwaves are
expected to round the trough reinforcing it through the forecast
period forcing a series of cold fronts through the area. The only
chance for precipitation will come on Thursday when one of the
aforementioned shortwaves drops through the northern Plains into
the local area and brings a slight chance for rain showers.
However, dry conditions in place make even that possibility
uncertain. Otherwise, temperatures will fluctuate through the next
week with several cold frontal passages.

The first of the aforementioned cold fronts will pass through the
area this morning ushering in cold air advection and keeping
temperatures in the 30s today. A warm front will push across the
forecast area overnight into tomorrow morning before a surface
trough pushes through during tomorrow afternoon. This should allow
for a much warmer day on Sunday with highs in mid 40s to mid 50s.
Another shortwave dropping through the Upper Midwest on Monday
morning will force another cold front through the area. However,
with no cold air behind the front, increased winds will actually
allow for better mixing and allow temperatures to rise into the
upper 40s to mid 50s. However, Canadian high pressure builds into
the area on Tuesday cooling temperatures. Expect highs in the mid
30s to lower 40s. Another warm front moves through on Wednesday
allowing temperatures to warm into the mid 40s to mid 50s.
However, temperatures will again cool on Thursday as a cold front
brings additional cloud cover and our slight chance for rain with
highs in the 40s. High pressure will dominate the end of next week
into the weekend with temperatures warming into the 50s by
Saturday.
