Service.

.DISCUSSION...
Dry conditions are expected to continue through at least Thursday.
There is a front that will cross the region overnight from the NNW
to SSE, but with limited moisture to work with, it should only
result in increased cloud coverage overnight and into Wednesday
morning. Cooler temperatures behind the front will help keep
relative humidity above critical thresholds despite drier air
moving into the area. Ensemble guidance suggests only a 10 to 20
percent chance of minimum RH falling below 40 percent.
