.DISCUSSION...
Little to no rain is forecast through Wednesday afternoon.
However, from Wednesday night through Thursday, low to medium
(20-50%) chances of showers and storms will return. Minimum
relative humidity values will stay above any critical thresholds
for the most part through Thursday. However, a few spots may dip
to around 35% Wednesday afternoon. Mixing heights are expected to
mainly reach between 3500-5800 feet on Wednesday and between
3000-5500 feet on Thursday. Light northerly transport winds on
Wednesday become west/southwesterly on Thursday and range between
5-10 mph. Lastly, fair daytime dispersions are forecast on
Wednesday with fair to generally good dispersions on Thursday.
Fog potential over the next few days: Other than sporadic patchy
fog in river valleys and next to bodies of water, fog is not
anticipated for most areas tonight. As moisture increases from mid
to late week, low to medium chances of patchy fog will return
each night/early morning.
Potential for Red Flag Conditions: None at this time.
