615 AM EDT Wed Apr 18 2018

Forecast is based on ignition time of 0700 EDT on April 18.

.DISCUSSION...
Mostly sunny conditions are expected across the inner Cape through
the day today. Winds will be mainly west-southwesterly, increasing
through the morning with sustained 15-20 mph and gusts to 30 mph
by late morning and early afternoon. Given this flow is onshore,
temperatures will likely top out in the mid to upper 40s. This
will limit min RH values to 40-50 percent.

If still ongoing, this evening winds slacken and shift more to
the south but generally remain around 10 mph. Rain showers move in
during the early morning hours with on and off rainfall expected
throughout the day.

OUTLOOK...Friday through Tuesday...
Scattered Showers are possible Friday, then drier weather for the
weekend. Temperatures generally remain below normal through the
weekend, warming into early next week.
