Weak upper level ridging is in place
across the Dakotas this morning while
very strong upper level low is poised to
move onshore over the Pacific Northwest.
At the surface, a large Canadian high
pressure system has moved over the
southern Great Plains leading to some
very cold temperatures over the southern
US and Gulf Coast. Another area of high
pressure is found over the northern
Rockies with a weak low over the Hudson
Bay. Locally, a weak warm front is
stretched from northwestern MN
southwestward through central SD. East
of the trough, winds are out of the
south with temperatures in the single
digits while west of the trough winds
are out of the west with temperatures
ranging from the mid-teens to lower 30s.
Skies are clear statewide.
That warm front will move east with time
today reaching the MN/SD border by
sundown. This will allow temperatures to
be much warmer than in previous days
with highs ranging from the 20s/30s over
eastern SD to the mid- to upper 40s over
western SD. Westerly winds from 10-20
mph and clear skies are expected.
Look for even warmer temperatures
tomorrow as weak upper level ridging
continues. High temperatures will be in
the upper 40s to mid-50s over western
SD, in the 40s over central SD, and in
the upper 30s to lower 40s over eastern
SD. Winds will be out of the southwest
from 5-15 mph. Skies are expected to be
mostly clear to partly cloudy.
No critical fire
weather is expected.
