Spot Forecast for I95 and Dunn Avenue...Florida Highway Patrol
National Weather Service Melbourne FL
607 PM EDT Sat Apr 29 2017

Forecast is based on request time of 1900 EDT on April 29.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...A high pressure ridge north of Florida will generate
a brisk southeast surface and transport flow across the area through
the weekend. These winds will push high temperatures into the upper
80s to mid 90s, resulting in high mixing heights that will lead to
very good to excellent dispersion across the area. While critical
relative humidity values are not expected to fall below 35 percent
for more than an hour or two tomorrow afternoon, the Fire Danger will
remain "high" to "very high" due to the high dispersion values. Other
than brief, isolated showers, conditions will remain dry through the
weekend.

Fog potential and other remarks...Surface and transport winds are
expected to remain strong enough to prevent fog formation through
the weekend.
