Spot Forecast for Spring Green West Rx...The Nature Conservancy
National Weather Service Milwaukee/Sullivan WI
420 AM CDT Sat Apr 13 2024

Forecast is based on ignition time of 0700 CDT on April 13.

Please contact the National Weather Service if conditions become
unrepresentative or if you have questions/concerns about this forecast.

.DISCUSSION...
Temperatures will rise starkly through the day from around 40 degrees
at ignition to 70+ degrees by the mid to late afternoon. Winds
initially from the west but will turn to largely be from the
south/southwest with gusts as high as 20 mph later this afternoon.
Given the location the fire could climb the elevation fairly
easily given the southerly winds. RH will fall to as low as 25
percent today but we should not expect much in the way of
potential for RH to drop below 25 percent.
