...Periods Of Heavy Rainfall Through Wednesday Night...
A frontal boundary is expected to slowly drop southward over the
state late tonight into Wednesday night. South winds ahead of the
front will continue to lift a warm and very moist air mass into
the region. As a result showers and storms will be on the
increase and will potentially contain heavy rainfall.
Latest data indicates total rainfall amounts could range from
2 to 4 inches through Wednesday night. Locally higher amounts
will be possible with thunderstorms. A good portion of the rain
will likely occur Wednesday or Wednesday night as a low pressure
system tracks along this front. Where the locally heavy rainfall
of 4 inches and possibly more will occur will depend on the
location of the front.
A rise on area streams and rivers will occur with these amounts.
Depending on rate of rainfall and runoff, flooding affects may
also include ponding of water in low lying areas and urban areas.
Locally higher excessive rainfall amounts with storms could lead
to flash flooding.
Stay tuned to later forecasts this week.
