Critical grassland fire danger

Winds are supposed to start accelerating throughout the morning and continue blowing straight through to Friday afternoon.  Combined with the (glorious, unseasonable) warmth and cracklingly dry air, our Grassland Fire Danger will hit the “Extreme” level by mid-afternoon…… hence, the Red Flag Warning, which will run from noon until 6 p.m. today.

 Here are the Butler County fire weather conditions for the next 24-36 hours:

Peak temperatures:  We’ll hit mid-60s today, followed by a high around 60 tomorrow.

Relative humidity:   The moisture bottoms out after lunch at 20% (or lower), then struggles to rise at all before sunset. Tomorrow will average around 50%.

Wind direction:  We’ll stay primarily south/southwest through mid- afternoon Friday; at that point, winds will start to switch to west/northwest.

Wind speeds:  The forecast calls for sustained winds in the mid-to-upper 20s through the night, accompanied by gusts of 35+ mph. Though sustained winds taper a bit after dawn (lower-20s) the gusts will remain quite fierce through mid-Friday. Breezes will finally fade away to single digits by sunset tomorrow (as the directional switch happens).

Grassland Fire Danger:  We’ll hit “Very High” at noon, peaking at the “Extreme” level around 3:00 p.m.  Our fire danger falls off steadily during the evening hours, hiccuping briefly around lunchtime tomorrow (at less than half of today’s value).
