.DISCUSSION...
Issued at 227 PM CST Sat Jan 10 2026

The main concern in the short term comes late this afternoon into
this evening as a strong PV anomaly will move through the area
pushing a cold front through the CWA. While moisture is lacking, the
forcing associated with this front will be strong, allowing
rain/snow showers to develop. No accumulation is expected however, a
snow shower coupled with gusty northwest winds 25-30mph may lead to
a brief, localized, reduction in visibility in a stronger shower.
Overnight into tomorrow, a surface ridge of high pressure will build
into the area from the northern Plains. This will allow winds to
weaken with morning lows falling into the upper teens to lower 20s.
the ridge of high pressure will remain over the area tomorrow
providing copious sunshine but weak mixing. this will hold highs
near seasonal normal in the mid 30s to lower 40s. Tomorrow night
into Monday, the surface ridge will slide south and east of the area
allowing downsloping westerly flow to prevail over the region. This
will allow highs to rise into the upper 40s to mid 50s.

The work week looks to be mainly dry as moisture will continue to be
lacking. Downslope westerly flow that develops on Monday will
continue into Tuesday allowing temperatures to soar nearly 20
degrees above normal with highs in the mid 50s to lower 60s. Tuesday
night a upper level trough with dig from the Upper Midwest into the
Great Lakes region. This will force a cold front through the area
with strong CAA in its wake. This will return highs to near normal
in the upper 30s to upper 40s. Thursday, the departing upper level
trough will leave the area under strong northwest flow aloft as a
Canadian surface ridge of high pressure build into the region. This
will keep highs near normal in the mid 30s to upper 40s. Thursday
night into Friday a upper level trough will dig from the northern
Plains into the Upper Midwest forcing an cold front through the
area. This will hold highs near normal in the upper 30s to upper
40s.
