Spot Forecast for Royal Trails / Bottany Woods Drive...Florida Highway Patrol
National Weather Service Melbourne FL
538 PM EDT Sat Apr 29 2017

Forecast is based on request time of 1800 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 allow high temperatures to reach the
lower 90s in vicinity of the fire site, resulting in high mixing 
heights that will lead to very good to excellent dispersion. While
critical relative humidity values are not expected to fall below
35 percent for more than an hour, the daytime Fire Danger will remain
"high" to "very high" especially due to the 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.
