Spot Forecast for Highland Prop-2...MDNR
National Weather Service Detroit/Pontiac MI
904 AM EDT Sun Apr 22 2018

Forecast is based on ignition time of 0900 EDT on April 22.
If conditions become unrepresentative...contact the National
Weather Service.

Easterly surface wind trajectories are forecasted today for all
of far western Oakland County as a pressure gradient sets up
between surface high pressure in Ontario and a low pressure system
passing through the southern United States. The gradient is
expected to remain strong enough today to limit any potential for
wind shifts associated from lake breezes. For the Highland area,
minimum RH will fall to around 19 to 20 percent between 2 PM and 6
PM EDT today.
