.DISCUSSION...
A cold front will cross the region this morning with high pressure
building over the area in its wake by this evening. The high will
maintain influence through Tuesday before the next cold front
pushes southeast across the local area Wednesday. High pressure
will return Thursday and Friday. Moist fuels from weekend rainfall
and mid-week rain chances will keep the fire weather risk low
this week.
