Water vapor shows upper ridge over the Rockies. At the surface,
high is over the far eastern Dakotas with warm advection pushing
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
with slightly cooler temps. Upper ridge then rebounds on Wednesday
into Thursday. A stronger upper trof is still progged to cross the
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.

lead to VFR conditions across all areas by 15z.
