temps into the 50s across the cwfa.

Upper ridge will peak over the Northern Plains on Monday, with
many areas reaching into the lower 60s. A weak upper wave will
flatten the ridge on Tuesday, pushing a cool front through the
Northern Plains. Moisture quite limited but could some light
showers in our northern zones. Breezy/windy W/NW winds expected

region late Thursday into Friday with a few more light rain/snow showers
possible. Could see elevated fire wx conditions Thursday with
gusty SW winds and low RH ahead of the upper trof. Mild and dry
for the weekend.
